So we know that the Mazda MX-5 Miata will either use a 2.0L Skyactiv-G for markets outside of North America or a 2.5L Skyactiv-G for North America. But a report from Motoring.com.au says there is a more powerful Miata in the cards. "We will have this ND-series model for maybe ten years, which gives us plenty of time to make many variants. And yes, a turbocharged or MPS variant is one of the options we will definitely consider," said Kudo Hidetoshi, Mazda's head of global public relations. Why turbocharging and not using a larger displacement Skyactiv engine? It would allow Mazda to keep some of the weight loss and 50:50 weight distribution. "[Generally speaking] turbocharging is preferable, even to a V6 now. We can use a lighter engine with the same or more power, and achieve [the] emissions and fuel consumption we need," said Hidetoshi. Source: Motoring.com.au -
G. David Felt - Staff Writer Alternative Energy - www.cheersandgears.com Right-of-Way, to give Power to the People in Seattle! Seattle in moving forward to address climate change is using their easement rights all over the city to expand their charging program. Seattle reserves the first 8 feet around your property as an easement that they can come on and pretty much do anything they want. With Seattle DOT EVCROW program, seattle is hoping to push beyond the few thousand charging stations around the city and make it 10's of thousands of charging stations by allowing public and private EV charging infrastructure providers to install EV charging stations on non-residential streets / properties throughout the city to expand the ability for charging of EV / Plug-in Hybrids. The goal is to have 30% plus of all registered auto's to be EV's by 2030. This Electric Vehicle Charging in the public right of way pilot program (EVCROW) is about speeding up the process and addressing the complexity to implement EV chargers everywhere. This program will run till July18th 2018 allowing folks to more easily install EV chargers and the City can see how they can streamline and simplify the installation and use of EV chargers. It looks like people could end up with public chargers on their property that faces the streets so others can charge up. While I am a huge EV fan, not sure I like the city taking over and using my private property as a charge station. What do you think? Seattle DOT Story

If you have read any review of the all-new Subaru Impreza, then you'll know there is one issue that many have pointed out - the anemic 2.0L four-cylinder. Masahiko Inoue, Subaru project general manager product and portfolio division told CarAdvice that he has been getting a lot of complaints with this engine. “Everybody is requesting from me a more powerful engine. Everybody thinks it needs more power. They are satisfied, they understand the Subaru Global Platform and the new 2.0-litre engine – but needing more power is a common complaint from everybody,” said Inoue. Inoue said the brand is looking at various options to solve this issue such as using a larger displacement engine (possibly the 2.5L from the Forester), turbocharging, or even a hybrid. But the final decision ultimately rests on how well the Impreza and sister model, the XV (Crosstrek for North America) sells. “Of course, we are studying, and we are now studying one of the options: a 2.4- or 2.5-litre engine, downsized and turbocharged, and power supported by motor, a hybrid. Every way we are studying for the next model, or the future model," said Inoue. “But we cannot spend money on this vehicle, because this is an entry vehicle for Subaru. We have to keep competitive with the cost for the entry vehicles, so if the turbocharged model is requested, maybe it will go to the Forester, or the Levorg, or another vehicle.” Source: CarAdvice View full article -

Sports and supercars have been stepping up with power it seems with every new model. There comes a point where the question is raised is there such thing as too much power. Someone at Porsche believes so. Andreas Preuninger, the head of Porsche’s GT division (group behind the 911 GT3) tells Car Magazine that future GT models will pass on the horsepower wars. "I’m not a believer in this horsepower monster, up, up, up, more, more, more. For my personal tastes, around 500bhp is enough, because 700-800bhp calls for bigger brakes, sturdier suspension, it gets heavier and heavier logically," said Preuninger. Preuninger went on to suggest that future GT and RS models will focus on shedding weight and hit a power-to-weight ratio, not adding 50 horsepower for each generation. Now you might think that Porsche will shrink the power that comes out of their engines for these models. Preuninger says the automaker will not do that. Source: Car Magazine View full article

Five months after Chevrolet revealed to the world the 2015 Corvette Z06, the brand has announced the final performance numbers and they are impressive to say in the least. When the model was revealed at the Detroit Auto Show, Chevrolet said the Z06 was producing 'at least 625 horsepower', but they needed to do final testing to get the ratings. Well, the Z06's supercharged 6.2L V8 has been SAE-certified and is rated at 650 horsepower and 650 pound-feet of torque. Not only is this the most powerful production Corvette, it also happens to be the most powerful production model ever built by GM. To put those numbers in perspective, the Z06 is bested by models such as, Ferrari LaFerrari McLaren P1 Porsche 918 Spyder Ferrari F12 Berlinetta Lamborghini Aventador Ferrari FF More impressive is the stats for torque. At idle, Chevrolet claims that 457 pound-feet of torque is available, and that 96 percent of peak torque arrives by 2,800 rpm. “The LT4 small block sets a new benchmark for power and torque at GM,” said Steve Kiefer, vice president, GM Powertrain Engineering. “The engine also puts the new Corvette Z06 on par with the most powerful supercars offered in America, while delivering performance with impeccable manners that make it suitable for daily driving.” Source: Chevrolet William Maley is a staff writer for Cheers & Gears. He can be reached at [email protected] you can follow him on twitter at @realmudmonster. Press Release is on Page 2 2015 Corvette Z06 Rated at 650 Horsepower Supercharged LT4 V-8 engine is the most powerful ever from Chevrolet DETROIT – The all-new 2015 Corvette Z06 is the most powerful production car ever from General Motors and one of a few production cars available in the United States that delivers more than 600 horsepower. The Z06's LT4 supercharged 6.2L V-8 engine is SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650 lb-ft of torque (881 Nm) at 3,600 rpm. "The LT4 Small Block sets a new benchmark for power and torque at GM," said Steve Kiefer, vice president, GM Powertrain Engineering. "The engine also puts the new Corvette Z06 on par with the most powerful supercars offered in America, while delivering performance with impeccable manners that make it suitable for daily driving." Compared with other supercar engines, the LT4 is a veritable fountain of low-end torque, producing 457 lb-ft (619 Nm) just off idle and 625 lb-ft (847 Nm) by only 2,800 rpm. The V-12-powered Ferrari F12 Berlinetta, for example, produces about 28 percent less torque than the Z06, despite offering about 12 percent more horsepower – and its peak torque isn't achieved until 6,000 rpm. The LT4 maintains 90 percent of its peak torque, or 592 lb-ft (802 Nm), from 2,500 to 5,400 rpm. The new LT4 engine eclipses the Porsche 911 Turbo S engine's peak power levels by 90 horsepower (67 kW) and 134 lb-ft of torque (182 Nm). "Torque is the pulling power of an engine and the LT4's abundance of it at every rpm in the engine's speed range helps the 2015 Corvette Z06 accelerate quicker and respond nearly instantaneously," said Jordan Lee, chief engineer for Small Block engines. "It's the very definition of power on demand." The new Z06 engine produces 40 percent more peak torque (180 lb-ft / 244 Nm) than the previous-generation's 7.0L LS7 engine – and 7.5 percent more than the supercharged 2013 Corvette ZR1's 604 lb-ft (819 Nm). At 3,200 rpm, the new LT4 surpasses the LS7 by 208 lb-ft of torque (252 Nm). On the horsepower side of the graph, the LT4's 650-hp rating is 29 percent greater than the LS7's 505 horsepower (376 kW), and 12 horses more than the ZR1's LS9 engine. "The new LT4 engine builds on the design strengths of our previous supercharged engine and leverages the technologies introduced on the Corvette Stingray – direct injection, cylinder deactivation and continuously variable valve timing – to take Corvette performance to an all-new plateau," said Lee. "Our new, very compact supercharger also helps the engine make power more quickly, and perhaps more importantly, it helps produce more torque earlier in the rpm band." "It's also worth mentioning that the LT4's supercar performance numbers are achieved with an engine that is nearly the same size as the very compact LT1 engine introduced in the 2014 Corvette Stingray," Lee said. "The power density of the LT4 makes it one of the smallest and lightest 650-hp engines in the industry." LT4 details The new LT4 engine is based on the same Gen 5 small block foundation as the Corvette Stingray's LT1 6.2L naturally aspirated engine, incorporating several unique features designed to support its higher output and the greater cylinder pressures created by forced induction, including: • Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional aluminum heads • Lightweight titanium intake valves • Machined, forged powder metal steel connecting rods for reduced reciprocating mass • High 10.0:1 compression ratio – for a forced-induction engine – enhances performance and efficiency and is enabled by direct injection • Forged aluminum pistons with unique, stronger structure to ensure strength under high cylinder pressures • Stainless steel exhaust manifolds and an aluminum balancer that are lighter than their LT1 counterparts • Standard dry-sump oiling system with a dual-pressure-control oil pump. A new 1.7L supercharger spins at up to 20,000 rpm – 5,000 rpm more than the supercharger on the Corvette ZR1's engine. The rotors are smaller in diameter, which contributes to their higher-rpm capability – and enables them to produce power-enhancing boost earlier in the rpm band. That boost is achieved more efficiently via a more direct discharge port that creates less turbulence, reducing heat and speeding airflow into the engine. "The Small Block's cam-in-block design heritage has always enabled very high performance and responsiveness in a small, compact package – an attribute amplified by the performance of our new supercharger's design," said Lee. The LT4 is assembled at the new Performance Build Center at GM's Bowling Green Assembly Plant and at GM's Tonawanda engine plant in New York. It is matched with a standard seven-speed manual transmission or an all-new, paddle-shift eight-speed automatic transmission built in Toledo, Ohio. Designed to deliver shift responses on par with the world's best dual-clutch transmissions, it is the first automatic offered in a Z06. It also makes the Z06 one of the few cars this powerful to offer the choice of a conventional manual transmission or an eight-speed automatic. The 2015 Corvette Z06 goes on sale in early 2015. -

"The Small Block's cam-in-block design heritage has always enabled very high performance and responsiveness in a small, compact package – an attribute amplified by the performance of our new supercharger's design," said Lee. The LT4 is assembled at the new Performance Build Center at GM's Bowling Green Assembly Plant and at GM's Tonawanda engine plant in New York. It is matched with a standard seven-speed manual transmission or an all-new, paddle-shift eight-speed automatic transmission built in Toledo, Ohio. Designed to deliver shift responses on par with the world's best dual-clutch transmissions, it is the first automatic offered in a Z06. It also makes the Z06 one of the few cars this powerful to offer the choice of a conventional manual transmission or an eight-speed automatic. The 2015 Corvette Z06 goes on sale in early 2015.
