Volkswagen is introducing a new generation of diesel engines with the 2.0 TDI Evo. This new engine is said to greatly undercut the limits of the tough new Euro 6d-Temp emissions standards. Volkwagen posted an interview with Sebastian Willmann, the Head of Diesel Engine Development at Volkswagen. In that interview he says that VW was able to reduce fuel consumption by 0.4 L/100km compared to the previous engine and reduce CO2 emissions by 10g/km. They did both of these things while also increasing power output. He further went on to explain that while there is a stigma surrounding diesel engines because of dieselgate, the diesel is still quite popular for its efficiency, range, and torque. Now, with this new engine, it is also substantially cleaner compared to prior engines. He says that diesels will remain especially effective for vehicles that require a longer range or extra torque for towing. These statements are in contrast to the direction that VW as a whole is taking in the segment of electric vehicles. VW has committed billions of euros to the development of an entire EV range. The first EV, the ID.3 is expected in Europe in early 2020 with top line models having a range of 342 miles on a charge. Reservations of the Volkswagen ID.3 topped 10,000 in its first 24 hours it was available. View full article

The EPA has officially released its assessment of the 2020 Jeep Wrangler EcoDiesel. The EcoDiesel is only available as a 4-door with an 8-speed automatic and in that configuration, the EcoDiesel manages to get 29 mpg highway, 22 mpg city, and 25 combined. That is slightly better than a 4x4 Ram 1500 with the same powertrain. The next closest model in terms of fuel efficiency is the 2-door, 4-cylinder, manual transmission, rear-wheel drive Wrangler at 24 highway mpg, 22 city mpg, and 23 combined. The diesel engine is a $4,000 option though so you may not ultimately save money. Instead, Jeep believes the EcoDiesel option is best suited for those who need the gobs of torque generated by the V6 diesel when going off-road. With 260 horsepower and 442 lb.-ft of torque, the Wrangler EcoDiesel has torque in spades. To the dismay of many, the Ecodiesel does come standard with electronic stop/start. If diesel isn't your thing, there is the 2.0T 4-cylinder which produces 270 horsepower and 295 lb.-ft of torque or the 3.6-liter Pentastar V6 which produces 285 horsepower and 260 lb.-ft of torque. Both engines also come with stop/start or can be upgraded to the eTorque system that smooths out the torque band and either engine is available with a manual transmission or 8-speed automatic.

As we reported last month, Jeep is adding a diesel to the Wrangler lineup. The 3.0-liter diesel will produce 260 horsepower and 442 lb-ft of torque and be paired only with the 8-speed automatic. Electronic Start-Stop is also standard issue. As for how much it is going to cost, be prepared to shell out up to an additional $6,000 over the base model. It breaks down like this: $4,000 for the diesel engine + $2,000 for the automatic transmission. All in all, it ends up being a $3,250 upgrade over a Wrangler with a Pentastar V6 and 8-speed automatic. The diesel will only be offered in 4-door trims of Sport, Sahara, and Rubicon. In the RAM 1500 with the same powertrain, highway fuel economy is rated for 30mpg. Expect the lighter but less aerodynamic Wrangler to match that once EPA numbers are finalized. Diesel Wranglers start down the production line in late November, but the order books are already open if you want to head down to the dealer and put your order in. View full article

Jeep is finally offering the 3.0-Liter EcoDiesel from the Ram 1500 in the Jeep Wrangler as a late availability option for 2020. For the Wrangler, the engine will produce 260 horsepower and 442 lb-ft of torque. The diesel will be offered on Sport, Sahara, and Rubicon editions, and only on 4 door models. The only transmission available to pair with the diesel is the 8-speed automatic. Electronic Start-Stop (ESS) is standard on the diesel and all other engine options. Other changes for the Wrangler include the addition of the mild-hybrid 48 volt eTorque system to either the 2.0-liter 4-cylinder turbo or the 3.6-liter Pentastar V6. The eTorque system takes the place of ESS and also smooths out the torque band. The 3.6 Pentastar produces 285 horsepower and 260 lb-ft of torque while the 2.0T produces 270 horsepower and 295 lb-ft of torque. These numbers hold true with or without the eTorque system. Only the Sahara trim gets eTorque. Two special editions take their place in the Wrangler lineup. The Willys edition is aimed at the off-road enthusiast. As far as hardware, it comes with a limited-slip differential, Rubicon rock rails and shots, heavy duty brakes, two-speed transfer case, and big 32-inch all-terrain tires. Visually, it gets 17-inch wheels with grey accents, all-weather floor mats, LED headlights and foglights, and a gloss black grille, along with the Willys badging. The Willys edition can come either in a 2-door for $35,235 or the 4-door for $38,735. A second special editions is primarily cosmetic. Called the Black & Tan edition (pictured above), it is mainly a retro looking that gets a tan soft-top, 17-inch Machine Granite wheels, tan cloths seats, side steps, and more. The Black & Tan edition is available on both 2-door and 4-door models. View full article

The EcoDiesel is a $4,995 option, or $3,000 premium over the 5.7-liter HEMI® V-8 eTorque ($3,300 on Tradesman, Big Horn/Lone Star, Rebel and Laramie base models). “The Ram 1500 EcoDiesel offers the best torque and towing among all half-ton diesel trucks,” said Reid Bigland, Head of Ram Brand. “Now with a 10-year track record, the Ram brand has emerged as a truck powertrain technology leader. Overall, the Ram 1500 EcoDiesel has outstanding pick-up truck capability and is truly in a class of its own.” The 2020 Ram 1500 EcoDiesel is available across all models and configurations, including a first-time offering in the Ram Rebel. The Ram 1500’s all-new 3.0-liter V-6 EcoDiesel leads the half-ton pickup truck segment in torque with 480 lb.-ft. and diesel towing capability of 12,560 pounds. The 2019 Ram 1500 Classic is also offered with the second-generation 3.0-liter EcoDiesel. Pricing for the Ram 1500 Classic EcoDiesel (Crew Cab 4x2) starts at $39,140, plus destination. Fuel economy ratings will be announced closer to when trucks go on sale early in the fourth quarter of this year. All-new EcoDiesel engine The third generation of the turbocharged EcoDiesel V-6 delivers increased torque and horsepower, along with superb fuel economy and minimal levels of noise, vibration and harshness (NVH) to meet the needs of Ram 1500 owners. In the 2020 Ram 1500, the 3.0-liter EcoDiesel V-6 is rated at a best-in-class 480 lb.-ft. of torque at 1,600 rpm, a 14 percent increase from the previous-generation EcoDiesel V-6, which peaks 400 rpm earlier. Horsepower increases 8 percent to 260 hp at 3,600 rpm. Several significant changes contribute to the new EcoDiesel’s improved dynamic and fuel economy performance. A new-generation water-cooled turbocharger with variable geometry is more efficient and provides improved response as engine rpms rise and fall Redesigned intake ports to improve engine performance and fuel economy Introduction of a dual, high-pressure and low-pressure exhaust gas recirculation system, a first for a diesel engine in North America. The EcoDiesel’s existing high-pressure EGR, with cooling exhaust gases drawn from the exhaust manifold, is augmented with a low-pressure EGR system that draws exhaust gases after they exit the diesel particulate filter. The addition of cooler, low-pressure exhaust gas makes a significant contribution to improved fuel economy and lower oxides of nitrogen (NOx) The compression ratio is changed to 16.0:1 from 16.5:1, which helps reduce exhaust emissions, particularly NOx Redesigned high-pressure (29,000 psi/2,000 bar) direct-injection fuel injector nozzles Combustion chamber geometry optimized to improve fuel economy Redesigned aluminum-alloy pistons improve fuel economy. The redesigned pistons use thinner piston rings and coating on the side skits to reduce friction The piston pin is offset 0.3 degrees from the centerline to reduce “piston slap” against the cylinder wall, minimizing NVH The lower portion of the two-piece oil sump uses a sandwiched polymer/metal material to reduce NVH The Selective Catalytic Reduction (SCR) system is 50 percent larger and incorporates a new-generation diesel oxidation catalyst with the Diesel Exhaust Fluid (DEF) system to reduce NOx New-generation brake system vacuum pump with low-friction blades contributes to improved fuel economy The upgrades build on the EcoDiesel V-6’s attributes and performance that made it a winner of Wards 10 Best Engines award for three consecutive years. The 3.0-liter EcoDiesel V-6 uses dual overhead camshafts (DOHC) with four valves per cylinder and a 60-degree angle between the cylinder banks. The block is cast with compacted graphite iron, which provides strength to dampen vibrations, but weighs less than grey cast iron. A compacted graphite iron bedplate adds rigidity to the block. The EcoDiesel V-6 uses a forged steel crankshaft and connecting rods for strength and durability. The aluminum alloy pistons are cooled on the underside via oil jets. Heat-treated aluminum cylinder heads use individual bearing caps to reduce friction and minimize NVH. The chain-driven overhead camshafts employ roller-finger followers. The 3.0-liter EcoDiesel V-6 is produced at the FCA Cento facility in Ferrara, Italy. Ram 1500 The 2020 Ram 1500 is the no-compromise benchmark for durability, technology, efficiency and convenience with features never before offered in a pickup. The Ram 1500 features up to 12,750 pounds of towing capability (5.7-liter HEMI V-8) and 2,300 pounds of payload. Ram’s eTorque mild hybrid system delivers improved fuel efficiency in both V-6 (standard) and V-8 configurations. As a segment disrupter, the new Uconnect 4C with a massive 12-inch touchscreen leads the pickup world in technology, featuring split-screen capability, 360-degree camera views and exclusive content from SiriusXM with 360L.

Once the diesel rolls out for the 2020 Silverado, it will take the title of most fuel efficient full-size truck on the market with an EPA rating of 23 City / 33 Highway / 27 Combined. The 3.0 liter inline six-cylinder diesel generates 277 hp and 460 lb-ft of torque. The diesel is mated to a 10-speed automatic transmission and also features a start stop system. In the Silverado, the price of the diesel engine is the same as upgrading to the 6.2 liter gasoline V8. It adds, $2,495 to the price of an LTZ or High Country model, or $3,890 to the cost of an LT or RST. Naturally, the engine will be available in the GMC Sierra as well. For those counting, this means the Sierra diesel is more efficient than the 4-cylinder diesel in the Chevy Colorado and GMC Canyon. It is also a less costly upgrade than on the two smaller trucks, there costing $5,745 on an LT GM is likely to hold the MPG title for a while as Ford's F-150 diesel was just released for 2019 and is rated for 22 City / 30 Highway / 25 Combined. Ram hasn't sold their 3.0 V6 Ecodiesel since 2017, but it was rated at 20 City / 27 highway / 23 combined. Honda does not field a full size truck. Nissan does, but does not offer a diesel in their standard duty models. Toyota does not offer a diesel at all, though it is rumored that the next Tundra will be coming with a twin-turbo V6 hybrid. The Silverado Diesel arrives in dealerships this fall. View full article

There will be one less engine option for the Chevrolet Equinox and GMC Terrain come the 2020 model year. The Car Connection first reported the news on the Equinox yesterday morning, while Autoblog followed with the Terrain news later in the day. Both stories reported the same reason for cancellation, they didn't sell. "We did discontinue the diesel engine option in the 2020 Chevrolet Equinox due to low demand," said Chevrolet spokesman Kevin Kelly. The news doesn't come as a shock to us. Diesel engines have gotten a bad rap since the Volkswagen diesel emission scandal came to light, causing sales to drop. The value argument was also tough for both models. A diesel Equinox started at $30,795. But only for $100 more, you could have gotten into the 2.0L turbo-four that offered better performance. Over at the Terrain, the diesel cost around $2,000 more than the 2.0 turbo-four. Diesel fuel is more expensive than its gas counterpart as well. That will leave the upcoming Mazda CX-5 Skyactiv-D as the only diesel option in the compact crossover class. But as we have noted previously, the diesel option is quite expensive (begins at $42,045) and fuel economy figures are disappointing (27 City/30 Highway/28 Combined).

After a brief hiatus, Ram is reintroducing the EcoDiesel for the 2020 Ram 1500 and in doing so, snatches away the torque crown held briefly by GM with their inline 6-cylinder diesel. The 3.0 L V6 Diesel in the 2020 Ram produces 480 lb-ft of torque at 1,600 rpm, 20 more than the 460 in the GM Inline-6, while horsepower increases to 260 hp at 3,600 rpm, a bit lower than the GM's 277 hp and the Ford Powerstroke 250 hp. The EcoDiesel is a DOHC V6 and achieves these numbers with a new generation water-cooled variable geometry turbo charger, higher compression ratio, redesigned cylinder heads, lightweight aluminum alloy pistons, and a redesigned EGR system. The EcoDiesel will be available in all models and configurations, including for the first time, the Ram Rebel. The 2019 Ram 1500 Classic is offered with the previous generation of this engine. The engine will be produced at FCA's facility in Ferrara, Italy. View full article

GM released power figures today for the new inline 6-cylinder diesel engine that will be available in the Chevrolet Silverado and GMC Sierra. Available at the same price as the 6.2 liter model, GM promises the new engine will change perceptions about diesel performance and refinement. GM recently announced the delay of the 3.0-liter diesel until the 2020 model year due to emissions certification delays. Paired with a 10-speed automatic transmission, the diesel produces an SAE-certified 277 horsepower and 460 lb-ft of torque with 95 percent of that torque being available at just 1,250 RPM. Torque peak comes at 1500 rpm and peak horsepower at 3750 rpm. The powertrain is setup to offer diesel exhaust braking to help slow the vehicle when the truck is in tow-haul mode, limiting the number of applications of the brakes to save on brake wear. The engine also has a user selective start-stop function to save additional fuel in city driving. 2019 CHEVROLET SILVERADO 3.0L DURAMAX TURBO-DIESEL SPECIFICATIONS Type: Duramax 3.0L DOHC Turbo Diesel I6 Bore & Stroke (in. / mm): 3.30 x 3.54 inches (84mm x 90mm) Block Material: Aluminum Cylinder Head Material: Aluminum Compression Ratio: 15.0: 1 Firing Order: 1-5-3-6-2-4 Valvetrain: Dual-overhead camshafts, four-valves per cylinder Air Delivery: Single variable-geometry turbocharger; intercooling system. 42.8-psi / 2.95 bar max boost Fuel Delivery: High-pressure, common-rail direct injection (36,250 psi / 2500 bar); electronic throttle valve Ignition System: Compression Max Engine Speed: 5100 rpm Additional Features: Continuously variable oil pump; engine oil cooler, automatic stop/start, Active Thermal Management, Emissions Control: Low-pressure Exhaust Gas Recirculation (EGR); Selective Catalyst Reduction on Filter (SCRF) Horsepower (hp / kW @ rpm): 277 / 204 @ 3750 (SAE certified) Torque (lb.-ft. / Nm @ rpm): 460 / 624 @ 1500 (SAE certified) Manufacturing Location (of globally sourced parts) Flint, Mich. Chevy Press release on page 2 2020 CHEVROLET SILVERADO’S NEW, ADVANCED 3.0L DURAMAX TURBO-DIESEL REDEFINES EXPECTATIONS No-compromise engine delivers refinement, performance and efficiency 2019-06-03 DETROIT — The all-new 2020 Chevrolet Silverado’s available 3.0L Duramax inline-six turbo-diesel engine adds choice and versatility for full-size truck customers, offering class-leading torque and horsepower in addition to focusing on fuel economy and capability. It is the first-ever inline-six turbo-diesel offered in Chevrolet’s full-size light-duty trucks. Chevrolet engineers started with a clean-sheet design and developed an all-new engine that leverages the efficiency and refinement advantages of the inline six-cylinder architecture and incorporates advanced combustion and emissions technologies to optimize performance and efficiency. It is priced identically to the 6.2L V-8 as a $2,495 premium over a 5.3L V-8 model or $3,890 over a 2.7L Turbo model. “From the moment the engine is started, to its idle, acceleration and highway cruising, the 3.0L Duramax performance will change perceptions of what a diesel engine can offer in refinement,” said Nicola Menarini, director for Diesel Truck Engine Program Execution. “With advanced technologies that draw on global diesel expertise, it’s a no-compromise choice for those who want the capability and driving range of a diesel in a light-duty truck.” Available on LT, RST, LTZ and High Country models, the 3.0L Duramax diesel rounds out the new Silverado’s range of six propulsion choices, each tailored to suit customers’ needs for performance, efficiency, technology and value. It is rated at an SAE-certified 277 horsepower and 460 lb-ft of torque delivering 95 percent of peak torque at just 1,250 rpm. Peak torque is sustained from 1,500 rpm through 3,000 rpm, providing a powerfully smooth and satisfying driving experience. The 3.0L Duramax is paired with GM’s 10L80 10-speed automatic transmission, featuring a centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness, reinforcing its performance, efficiency and refinement. This combination also offers exhaust braking, which uses the diesel engine’s compression to help slow the vehicle, requiring fewer brake applications by the driver when in Tow Haul mode. Innovative Engine Technologies The inline six-cylinder architecture offers inherent efficiency and refinement, but the team expanded with smart technology choices to help improve efficiency and weight while optimizing the truck experience. A lightweight aluminum block and cylinder head reduce overall mass, and Active Thermal Management enhances efficiency and cold-weather warm-up. Ceramic glow plugs also help with shorter heat-up times and a quicker cold start, meaning the engine block heater is not needed until -22 degrees F. Towing is an important part of owning a truck, and customers can gain additional confidence thanks to the exhaust brake available in tow-haul mode. The water charge air cooler, coupled with low pressure EGR, reduces time to torque. The variable geometry turbocharger helps provide a greater balance of performance and efficiency, and an electronically variable intake manifold helps optimize performance across the rpm band. Inherently efficient and balanced Compared to a DOHC V-6, the inline-six architecture offers greater efficiency from the reduced friction of operating only two camshafts and their associated valvetrain components. The I6 configuration offers the perfect balance of primary and secondary forces, without the need for balancing shafts. “In addition to reduced friction, the architecture enables smooth operation,” Menarini said. “The new Duramax 3.0L elevates the 2019 Silverado with one of the most refined and efficient diesel engines in the segment.” Along with supporting elements such as a tuned air induction system and other noise-attenuating elements, the 3.0L Duramax delivers exceptional quietness and smoothness at all engine speeds. All-aluminum construction and tough rotating assembly The 3.0L Duramax cylinder block is made of a cast aluminum alloy that provides the strength required to support the high combustion pressures that occur within a diesel engine, while also offering an approximately 25 percent mass savings over a comparable cast iron engine block. Iron cylinder liners are used within the aluminum block to insure truck durability. There are seven nodular iron main bearing caps that help ensure the block’s strength under those high combustion pressures, while also enabling accurate location of the rotating assembly. A deep-skirt block design, where the block casting extends below the crankshaft centerline, also contributes to the engine’s stiffness and refinement. It’s complemented by a stiffness-enhancing aluminum lower crankcase extension attached to the main bearing caps. The rotating assembly consists of a forged steel crankshaft, forged steel connecting rods and hypereutectic aluminum pistons. The alloys in the respective castings for the rods and pistons make them lightweight and durable. Silicon is blended with the aluminum for heat resistance and tolerance within the piston cylinders, which enhances performance and makes the engine quiet. A thick piston crown — the top of the piston — and reinforced top ring add strength to support the tremendous cylinder pressures enabled by turbocharging and the engine’s high 15.0:1 compression ratio. DOHC Cylinder Head and Rear Cam Drive Overhead camshafts offer a direct, efficient means of operating the valves, while four valves per cylinder activated by maintenance-free finger followers with hydraulic lash adjusters increase airflow in and out of the engine. This arrangement is integrated on the Duramax 3.0L’s lightweight aluminum cylinder head, which is topped with a lightweight composite cam cover that incorporates the crankcase ventilation and oil separation systems. A pair of lightweight, assembled camshafts actuates 28.35 mm diameter (1.12-inch) intake and 24.55 mm diameter (0.97-inch) exhaust valves. The camshaft drivetrain is uniquely located at the rear (flywheel side) of the engine, for greater refinement and packaging considerations for the comparatively long inline-six. A crankshaft-driven chain drives the high-pressure direct-injection fuel pump, while a chain driven by the fuel pump drives both intake and exhaust camshafts. A smaller belt drives the variable flow oil pump from the crankshaft. Additional Technology Highlights Variable geometry turbocharging enables the Duramax 3.0L engine to deliver class-leading horsepower with minimal effect on overall efficiency. The system uses closed loop controlled vanes position and sophisticated electronic controls to automatically adjust boost pressure to the desired value based on engine running conditions and instantaneous power demand. The liquid-cooled turbocharger features a low-friction ball-bearing shaft and is mounted close to the exhaust outlet of the engine for quicker spool-up of the turbine and quicker light-off of the exhaust catalyst. A water-to-air intercooling system produces a cooler higher density air charge for greater power. Maximum boost pressure is 43,5 psi (300 Kpa) absolute. Low-pressure EGR: The Duramax 3.0L utilizes new low-pressure Exhaust Gas Recirculation to optimize performance and efficiency. The EGR system diverts some of the engine-out exhaust gas and mixes it back into the fresh intake air stream, which is drawn into the cylinder head for combustion. That lowers combustion temperatures and rates. Traditionally, EGR systems in diesel applications recirculate exhaust gases between the two high-pressure points, the exhaust manifold(s) and intake manifold. However, it generally requires efficiency-robbing assistance from the turbocharger or other supporting elements to achieve the pressure differential required for sufficient EGR flow rates. The new low-pressure system adds to the high-pressure system, supporting continual adjustment of exhaust backpressure for more efficient operation. It recirculates gases between the low-pressure points in the exhaust system (downstream of the particulate filter) and after the compressor inlet. When the low-pressure EGR is activated by an electronically controlled valve, the engine burns exhaust gas that has already passed through the particulate filter. That increases the turbocharger’s efficiency, which helps overall vehicle efficiency without deteriorating the rate of particulate matter emitted by the engine. A variable intake manifold offers dual air intake pathways for each cylinder. Electronically controlled flaps — one for each cylinder — shorten or lengthen the airflow to each cylinder. This optimizes the airflow into the engine and improves performance and responsiveness across the rpm band, particularly at lower engine speeds. A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump. The engine uses low-friction Diesel Dexos 0W20 oil. Oil jets located in the block are employed for performance and temperature control. They target the inner core of the piston with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more power and enhance long-term durability than engines without the technology. Active Thermal Management helps the engine warm up quickly to achieve and maintain its optimal engine temperature for performance and efficiency over the entire engine operating range. The system uses a three-actuator rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it’s needed to warm up the engine to reduce friction and heat the passenger cabin or cools when needed for high-power operation. The Duramax 3.0L also features split cooling between the block and head. Common rail direct fuel injection of 2,500 bar (36,250 psi) helps generates class-leading horsepower and torque. The system’s pressure is generated by an engine-driven twin-piston pump sending fuel to solenoid-activated injectors with nine-hole nozzles that support precise metering of the fuel for a smooth idle and lower combustion noise. The fuel system is capable of multiple injections per combustion cycle — up to 10 times per injector — for more consistent and stable combustion performance that translates into smoothness and refinement, particularly at idle. Electronic throttle valve: The Duramax 3.0L features an electronic throttle valve to regulate intake manifold pressure in order to optimize exhaust gas recirculation rates. It also contributes to a smooth engine shutdown via a more controlled method of airflow reduction. Ceramic glow plugs used in the Duramax 3.0L heat up more quickly and hotter than conventional metal-based glow plugs, helping the engine start and heat up more quickly in cold weather. The Duramax 3.0L achieves unassisted and assisted starting temperatures of -22 F (-30 C) and -40 F (-40 C) respectively. Stop/start technology helps optimize efficiency in city driving. The driver-selectable system shuts off the engine at stoplights and other stop-and-go situations. The engine automatically restarts when the driver takes their foot off the brake.

GM is delaying the launch of the new inline-6 diesel engine bound for the GMC Sierra 1500 and Chevrolet Silverado 1500. No longer available for ordering on the 2019s, GM has pushed the availability into the 2020 model year. According the GM, the emissions certification process on the engine is taking longer than normal. Customers who ordered a 2019 Silverado or Sierra with the diesel engine will have their orders canceled and will need to resubmit the order for a 2020 model year vehicle once they become available for order. GM has yet to open orders for 2020 truck models with the diesel engine, but a GM spokesperson said that it will be "soon". Assuming the current pricing holds, the 3.0 liter Duramax diesel will be priced $2,495 over a 5.3 liter V8 and $2,890 over the 4-cylinder 2.7-liter turbo. Meanwhile for 2020, GM is expanding the availability of adaptive cruise control and the 10-speed automatic across the lineup. At Chevy, the Silverado will now have the optional 6.2 liter V8 on five out of the eight trim levels. The 6.2 V8 will be paired with the 10-speed automatic and available on the Custom Trail Boss, RST, LT Trail Box, LTZ, and High Country. At GMC, the CarbonPro box will be available at no additional cost when paired with certain other packages on the Sierra AT4 and Sierra Denali, while the double cab Sierra Elevation Trim will now also be available in a crew cab.

Jeep is rumored to be testing a Mercedes-Benz supplied 2.0 liter Turbo-Diesel in 14 test vehicles in the Detroit, Michigan area. However, it is unlikely that such a vehicle would be sold in the U.S. The most likely scenario is that this is testing for the European and Asian markets. The Compasses were converted by an independent supplier for FCA and the suspected engine of choice is the Mercedes-Benz OM654 2.0 diesel producing 192 HP and 295 lb-ft of torque. The engine was released in 2016 for the E-Class, but the engine was designed to be mounted in transverse applications as well. In the U.S., the Compass is only sold with a 2.4 liter gasoline engine. In Europe, the Compass comes with a two different 1.4-liter gasoline engines (140 hp an 170hp), two 2.0-liter diesel engines (140 hp and 170 hp), and a 1.6-liter diesel engine (120 hp). Which engine you can get largely depends on if the car is 4x4 or not. GM currently sells its compact crossovers with a 1.6-liter turbo diesel, and Mazda finally unveiled their diesel CX-5. We think that this diesel Compass would be a good fit in the U.S. and should FCA be reading this, please bring it here. View full article

The European car market as a whole has been in decline for six consecutive months as of March 2019 with 19 out of 27 markets posting declines. March numbers were down 3.6 percent over the same month in 2018. Looking at the first quarter of 2019 paints an even bleaker picture with only 6 countries recording growth. While overall demand is down, the demand for electric vehicles grows. The sales of EVs exceeded 100,000 units for the first time ever with a total of 125,400 EV and PHEVs sold. That is an increase of 31%, mostly in Germany, Norway, Spain, and the Netherlands. Much of that growth is attributed to the Tesla Model 3 entering the market and becoming Europe's top selling electric car. Model 3 sales jumped from 3,747 units in February to 15,755 units in March. It was also the best selling premium mid-size car in the EU. Diesel on the other hand is facing continuing losses. Registrations of new diesels have moved from 44.8 percent of all registrations in March 2017 to 31.2 percent of all registrations in March 2019. Analysts expect diesel to continue to fade as more cities put in diesel bans and stricter emissions regulations come into effect. View full article

It seems like forever since Mazda announced plans to introduce a diesel engine for the U.S. market. You need to go all the way back to 2010 when the Japanese automaker first announced its intentions, with the ambitious goal of meeting stringent emissions standards without a costly exhaust aftertreatment system. Ambitious and one that would end up going nowhere. After almost a decade of various delays, changing plans, and the elephant in the room that is the Volkswagen diesel emission scandal, Mazda has finally announced that they will begin selling a CX-5 turbodiesel beginning this year. No launch window was given, but the company has announced they are beginning to take pre-orders. Time to get excited right? Well, no. On paper, the CX-5 Diesel is quite disappointing. The diesel engine in question is a 2.2L Skyactiv-D four-cylinder producing 168 horsepower and 290 pound-feet of torque (slightly lower from the 170 and 310 figures we have been reporting previously). That's less than the 250 horsepower and 310 pound-feet of torque for the optional turbocharged 2.5L. Fuel economy isn't a bright spot either. EPA figures for the 2.2 are 27 city, 30 highway and 28 combined - not major improvements over the standard 2.5 four-cylinder of 24/30/26. We should note that Mazda is only planning on offering diesel with all-wheel drive. The front-wheel drive variant we reported on last August doesn't seem to exist at the moment. But the final nail in the coffin is the price tag. Mazda is only offering the diesel on the top Signature trim for a base price of $42,045, including $1,045 destination charge. This is a sizeable jump from the Signature with the 2.5T at $38,235. It's evident that Mazda is trying to leverage the diesel engine as part of its premium ambitions. But we can't but wonder if Mazda ultimately stuck with this project just to show they could do it. With all of the delays, so-so fuel economy, and high price tag, it will be a hard sell to consumers. Source: Mazda 2019 MAZDA CX-5 SIGNATURE DIESEL ARRIVES AT NEW YORK INTERNATIONAL AUTO SHOW MAZDA’S PATH TO PREMIUM CONTINUES WITH THE ADDITION OF SKYACTIV-D 2.2 TO U.S. ENGINE LINEUP NEW YORK (April 17, 2019) – Mazda North American Operations (MNAO) announced today at the 2019 New York International Auto Show the arrival of the 2019 Mazda CX-5 Signature AWD featuring the Skyactiv-D 2.2-liter diesel engine with pre-sales beginning immediately. The show is open to the public from April 19-28. In his speech today, Chairman and CEO of MNAO, Masahiro Moro shared updates on Mazda’s journey to Japanese premium along with the ground breaking of Mazda Toyota Manufacturing, U.S.A., Inc. (MTMUS) and the recent leadership enhancements. He introduced Jeffrey Guyton as the new President of MNAO, who brings over 20 years of executive experience from Mazda Motor Europe (MME), as well as vast knowledge related to Mazda’s biggest announcement of the day – the long-awaited arrival of Mazda’s diesel engine to the U.S. As Mazda continues toward premium, Guyton and Moro welcomed the addition of the Skyactiv-D 2.2 engine in the U.S. with the expansion of the powertrain lineup in the CX-5, the brand’s best-selling vehicle in the region. Skyactiv-D 2.2 provides Mazda fans another option to enjoy the popular compact crossover SUV and addresses the strong demand for a diesel engine in the U.S. that offers a premium driving experience. “As Mazda continues our climb toward premium, we will offer more powertrain choices that premium customers expect,” said Guyton. “I am happy to share that Mazda’s Skyactiv-D 2.2-liter diesel engine is joining the U.S. powertrain lineup with our debut model, the 2019 CX-5 Signature AWD with Skyactiv-D.” The 2019 CX-5 Signature AWD with Skyactiv-D 2.2 provides a high torque driving experience and revs freely at high rpms. The Skyactiv-D 2.2 engine is estimated to deliver 168 horsepower at 4,000 rpm and 290 lb-ft of torque at 2,000 rpm with an EPA estimated 27 mpg on city, 30 mpg on highway and 28 mpg overall. A sequential twin turbocharger realizes smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque (up to the 5,500 rpm rev limit). Mazda worked closely with all proper federal and state agencies, such as the California Air Resources Board (CARB), to ensure that the Skyactiv-D 2.2 engine meets the required emission standards and passes all appropriate regulations. With an MSRP[1]of $41,000, the 2019 CX-5 Signature AWD with Skyactiv-D 2.2 is available in four color options: Jet Black or premium paint colors; Snowflake White Pearl, Soul Red Crystal and Machine Gray Metallic. Pre-sale for the 2019 Mazda CX-5 Signature AWD with Skyactiv-D 2.2-liter diesel engine is available now.
