You realize that most Jaguar, BMW, Mercedes and Audis have loads of low end torque. And the GM 2.4 liter and 3.6 liter engines make similar torque to the Asians, often at even higher RPM. But to your point, more gears should help to keep the engine in the sweet spot and get more out of it. The switch from 4-speed to 6 allowed for downsized engines, and the 4-cylinder replacing the V6 in many cars. I remember reading a while back that Mercedes thought 9-speed was the ideal and that 10+ was of no benefit, but of course they are making a 9-speed so that could be a biased point. I will say that the Mercedes 7-speed is the best transmission I ever experienced, so I suspect their 9-speed will be great too. Infiniti's 7-speed though is one of those gear skippers and it hunts for 6th or 7th to save fuel then throws itself down to 2 if you get on the gas, it makes for a jerky car to drive.

BMW News: Rumorpile: 4-Series Means Coupes, Convertibles, and Gran Coup
smk4565 replied to William Maley's topic in BMW
4-series is dumb to me, just like Audi A5 is dumb. It should be 3-series sedan, coupe, convertible, wagon. Multiple body styles on the 3 as it is now. 6-series/Gran Coupe are niche vehicles anyway so I don't mind the use of 6 there, especially since it is more 7-series than 5-series now. Mercedes is going the opposite direction and I think for the better. C-class, E-class, S-class will all have a coupe, no more CLK or CL. Makes more sense. Much like Cadillac having CTS in 3 body styles makes sense, calling it CTS, CTC, CTW, or CTS2, CTS4, or something would be stupid. -
Bi-Turbo V6 Aluminum Body to cut weight. Oh wait, Ford already did that, but better late than never.
-
It is still FWD and still not what a Cadillac should be. I don't think they could get it under 3200 lbs either with the Delta II platform with the added weight of the hybrid system. Unless they use carbon fiber body panels, but then cost is way up. Should just make a diesel ATS and CTS instead because right now hybrids and electric cars suck, unless maybe the top of the line Tesla model S or the Mercedes SLS AMG Electric Drive which has 740 hp and 737 lb-ft of torque and AWD. If Cadillac wants to build a 700 hp electric CTS-V I am on board for that.
-
Maybe GM should spend some money on a new transmission then. And use bi-turbo VVT, DI, etc. No one is telling GM that they can't, shell out the money and build a new engine with all that stuff on it. We can compare the Bentley Mulsanne 6.75 liter bi-turbo pushrod V8 with the S63 AMG 5.5 liter bi-turbo DOHC V8. Bentley makes 505 hp, and 752 lb-ft put through and 8-speed transmission and gets 11/18 mpg. S63 AMG makes 564 hp and 664 lb-ft sent through a 7-speed transmission and gets 15/23 mpg. Both are similar in weight and the Bentley has an extra gear which should offset the weight advantage the S63 has. Perhaps the closest comparison is the Genesis 5.0 and the 300C because both have VVT. The Genesis is rated at 17/26, the 300C at 16/25 mpg even with cylinder deactivation. But again the Genesis has a better transmission, and the Hyundai 5.0 makes 66 more hp than the Hemi.
-
And that engine is gone, the replacement gets up to 563 hp and 664 lb-ft and 15/23 mpg in the S63, slightly less power but 1 mpg more in the E63. The E63 gets 16/24 mpg now. The CTS-V gets 12/18 mpg with automatic and weighs 174 lbs more than the E63, so not really seeing the weight and fuel economy savings of the pushrod there. The sad thing is the CTS-V is the only GM sedan available with a V8 anymore and Ford doesn't have any. The V8 sedan is dying, outside of Mercedes where it seems to be alive and well. Even BMW is pushing the straight six all the up to $100k cars.

Well i can see DOHC V8 having better image...but ..what else? What is there i can use in real live that DOHC v8 does better than OHV v8? Is coyote v8 better than LS3? Yes, best DOHC v8 engine is maybe better than best V8 OHv (but i'm still interested to know which are criterias) but how much does best DOHC v8 cost? Does GM has car in which they could put that engine and price it accordingly? Also,just to see which criteria do you consider important (i don't mean to be offensive just curious) here is a list of some DOHC engines..which one do you think is(just the engine not the car) better? And why? 5.0 l v8 TT from koenigsegg agera 4.5 l v8 from Ferrari italia 458 M838 TT from Mclaren 6.5 l v12 (L539) from Lamborghini aventador Synergy V8 AMG M159 AMG M157 Koenigsegg has the best engine, it makes 1,000 hp end of story. The McLaren V8 is impressive for the amount of power it makes from a small displacement, but the AMG M157 wins there. The AMG engine has almost as much horsepower but way more torque and is more efficient. The Ferrari Italia V8 sounds good, but I'd probably rather have the McLaren or Mercedes V8 instead.

Hit the nail on the head. Not really, he hit his thumb. SOHC and DOHC are not equivalent and if you bothered to read the rest of the thread, you'd see how. I did read the rest, SOHC is worse than DOHC but no one really makes them any more either. But either way, OHC is better than pushrod, the example of the Crown Vic is because the engine was left the same basically form the early 90s. Comparing a bad SOHC V8 to the best pushrod on the market isn't really making any sense. That is like comparing the GM 3900 V6 to the Nissan GT-R V6.

Hyundai had no V8 5 years ago and had to build one from scratch. And they built DOHC, they spent a lot of money on that engine, it could have been anything they wanted and they went with DOHC. The only reason GM and Chrysler still use them is lack of funds to design the replacement. I understand the argument of GM should continue to use the pushrod rather than spend the money to make a DOHC V8 from scratch at a time when V8s are dying, maybe it isn't a good investment. But I don't buy that pushrods are better, why doesn't Lamborghini or Ferrari use a pushrod V12 or V8 then? How are Lexus, Audi, Mercedes, Aston Martin, McLaren, Jaguar, etc all wrong, and Chrysler/Dodge and Chevy are using the superior engine?

I saw 2 yesterday, although they were both beige, could have been the same car that I saw twice. The only weird thing about it is the hood looks really low and the trunk looks really high. Seems off in proportion. The LED lights on the front look better than the CTS's though.
-
I never experienced a Rolls V12, but that car has loads of sound deadening also. But the BMW inline six is better than their V8 in a lot of ways. The engine is just so smooth, balanced, it revs easily, never sounds harsh. And it is good in a luxury car or good in a sports car.
-
All of you that think you don't need a DOHC V8 don't own one. Once you get used to having a DOHC V8 it is hard to go to anything else. The only thing I have driven that is better is the BMW straight six, that is the smoothest engine out there. Fuel economy concerns though will push the DOHC V8 crowd like myself to DOHC V6s, possibly with turbo or supercharger.
-
At the way the market is moving away from V8s, there might not be much need for one anyway. The Corvette loyalists will buy it whatever the engine is, although Corvette sales are shrinking and the fan base getting older and older. Pick-ups will sell with anything due to so few brand options, and the V6 will become more common there anyway. And the Cadillac flagship will be DOA anyway, and that is the only car that really needs a DOHC V8. The CTS could use one since the E-class and 5-series have one, but they will sell the CTS at a discount to compensate for lack of a V8, much like Audi and Lexus do. And that is why the E and 5 combine to sell 9,000 a month and the A6 and GS sell 2,000, with a smaller profit margin to boot.

If the Encore were a Verano based crossover with the 2.4 liter and the same price point, it might sell. But did Buick notice that this has a higher base price (though slightly lower loaded price) than a Volkswagen Tiguan? And did they notice that the Tiguan even in base form has the award winning VW/Audi 2.0T engine with 200 hp and 207 lb-ft @1700 rpm. 138 hp vs 200 hp, really? And I think the Tiguan has a better interior also.
-
GM needs a 1.6T, that could get them up to 160 hp, rather than the 138 hp of the 1.4T. The 1.4T is okay for a base engine, but they need something else to offer. Especially with Hyundai having a 200 hp turbo 4, Civic has a 197 hp, Ford has the Ecoboost, etc. It is as if GM's small cars are only there for CAFE purposes so they can keep selling Silverados. Sort of what led them to trouble in the 90s.
-
A Kia Soul even has 164 hp, I can't see people buying paying near $30k when optioned up for the Encore. It doesn't look very good because of how short and tall it is, interior looks like it is a dressed up Sonic, and a weak engine. The Encore and Verano do give Buick two sub $25k cars though to try to attract buyers to the brand, or people that in the past would have looked to Saturn or Mercury. The Verano I think is a good idea, the Encore I however I do not.
-
It will still be a cheaper version of an A8, so how much cheaper and how well equipped is the question. Also with the A8 going with a V6 as the base engine, you know the Phaeton has to, and the Phaeton probably will not get a V8. Then you have to ask do people want to pay $60k for a V6 Volkswagen that looks like a Passat with LEDs, when they could otherwise buy an A6, spend more and get an A8, or get a V8 Equus etc.
-
The Encalve and Acadia are hardly new, they are the same car with some slight cosmetic changes. It will be interesting what they do with the LaCrosse and Regal, if they just get a slight refresh like the Enclave or if they do more, such as move the LaCrosse up market a little, to say $35k base to make room for the Impala. GM needs a compact pickup that is fuel efficient and doesn't suck. That is a big void in their lineup right now, I am curious what they do with the Canyon to fix it.
-
Verano is a better deal. If the Encore had some more motor I would say the price is worth it, but with some options you are looking at $30k for a 1.4 liter with 138 hp. If the Encore had more like 170 hp and make it not seem like you are getting a Chevy Sonic SUV with leather.

Lame, if they are going to build a 94 mpg electric type car it should have RWD! -
Cadillac News: Next CTS To Be More "Sophisticated"
smk4565 replied to William Maley's topic in Cadillac
It needs sophistication, but I think a strength of Cadillac styling is the angles. The Evoq concept for example was very well done, and I think the XLR had very good exterior styling, just the wrong interior and wrong price tag. I don't care much for the rounded off Cadillac style, the ATS seems too round, and that rounded off blandness killed the STS. The sophistication is more needed on the interior and under the hood though.- 4 replies

I'd be surprised if they go 6.2 liters again. If they do, I can't see them sustaining it for very long with CAFE. Unless they keep the 6.2 liter V8 and don't offer it in many vehicles. GM still needs to find another 4-5 mpg for CAFE.
-
Needs a real hybrid, the Fusion gets 47/47 mpg, makes the Malibu Eco look pretty sad. Not a fan of the back end styling, it costs too much for what you get, design of the interior is pretty good, but it could use some more in build quality. Haven't driven one to know how it feels, but the Malibu has nothing at all that wows me to make it even worth considering. The 2013 Fusion looks fantastic and gets 47 mpg, that is going to get people to the dealership to look at one.

Cadillac News: Spying: Cadillac ELR Sweating Out In The Desert
smk4565 replied to William Maley's topic in Cadillac
Yes it should be, unless they botch it. But I like that the car is being built with the purpose of being a world class luxury car in mind, rather than adding chrome and leather to an Impala or something.
