2012 Chevrolet Corvette Z06 – Click above for high-res image gallery

According to TheDetroitBureau.com, General Motors is planning to alter its strategy with the next-generation Corvette to appeal to a wider range of customers. Traditionally, the Corvette has always been offered with high-displacement eight-cylinder powertrains, but according to sources within GM, the C7 Corvette may also offer a small, turbocharged V8.

Just how small, exactly? TDB reports that the next Corvette's European-style V8 could measure in at just over 3.0 liters, using an overhead-cam setup and dry sump oil system. With the aid of turbocharging, unnamed GM sources expect that this engine will deliver "in excess of 400 horsepower," or about 125 hp per liter. What's more, the smaller V8 could be of the extremely high-revving nature, with TDB citing that engine revs could handle up to 10,000 RPM.

GM's North American president, Mark Reuss, previously told The Bureau that the C7 Corvette will "target a very different sort of buyer."

However, traditional V8 enthusiasts need not worry, as the story states that a full range of engines will be available, including the classic larger displacement units that have traditionally found a home in the Corvette.

Of course, the rumormill about exactly what's in store for the C7 Corvette continues to swirl. We've heard everything from a mid-engine layout to a split rear window design that pays tribute to the 1963 'Vette. Whatever the case, GM just invested $131 million in the Bowling Green, Kentucky plant that builds the Corvette and the all-new model is expected to arrive within the next two to three years.

      I think if they could figure out how to make the HP and still get the mileage I don't think many would have a problem with it, but as my list below of currently available small cube VS Big cube cars shows the big cube cars fare much better in the MPG when compared to small cube cars OF EQUAL HORSEPOWER. Small cubic inch cars Porsche 977 GT2 (3.6 Liter) makes 530 HP and gets 18.8 (US) MPG (12.5L/100km) BMW M5 E60 (5 Liters) makes 500 HP and gets 17 MPG (13.835L/100km) Ferrari 599 GTB makes (5.9 Liter) 620 HP and gets 15 MPG (15.68L/100km) Mercedes S65 AMG (5.5 Liter) makes 603 HP and gets 17 MPG (13.835L/100km) Big cubic inch cars Corvette Z06 (7.0 Liters) makes 505 HP and gets 24 MPG (9.799L/100km) Corvette ZR1 (6.2 Liters) makes 638 HP and gets 20 MPG (11.76L/100km) Dodge Viper (8.4 Liters) makes 600 HP and gets 22 MPG (10.69L/100km) Many will say the big cube cars are running a taller gear ratio which is true, but a Big cube motor usually has a powerband of around 1000 RPM to 6500 RPM, which means it is in it's maximum efficiency when cruising 70 MPH down the highway at 1000 RPM. On the other hand a small cube motor with a powerband of around 5000 to 10,000 RPM is not very efficient when operating below it's powerband, so simply putting a taller gear in a high revving motor is not going to result in better mileage. The simple fact of the matter is if the Porsche, BMW, Ferrari, and Mercedes listed above could get better mileage with a taller gear ratio, why didn't they do it?

        You can't compare a BMW M5 and Merc S65/SL65 against the Corvette, vehicle weights are way to disparate to compare properly. You need vehicles of similar weight and horsepower to compare and get a good set of data. Regardless, the LS family is known to be reliable, and powerful, and fuel efficient while also being much lighter than the similar competition.

        I completely agree. Thanks for doing the research and posting the numbers for people to CLEARLY see! You did leave out the fact that the Chevy engines are actually lighter than their Euro counterparts. Also, I would love to see a slightly smaller and possibly turbo'ed Vette. Say 5.5 or back to 5.7 liter with turbo? I mean they got 420hp out of the 6liter a few years ago. Why not go to this: Multi Displacement. 5.7liter +turbo = 465hp. (I know it's a low number but it still will be higher than the current base one). Louvers on the front like the cobalt for airflow. Descreased drag (even though it's already very good) Lighter Rims /rolling rotational mass This should net a few more mpg with the multi displacement. Could it possibly be the first 400hp with 30mpg highway rating?

      The sound that kind of engine would make could be nothing short of a choir of angels being beaten by another choir of angels.

      SOunds like they are giving consumers so many choices its going to be a hard choice for a guy like me.....this is a good problem to have.

      A small-displacement turbo V8 with a potential 10K rpm redline? Yes, please! VTEC this!

      Probably the coolest report I've read on the C7, a small displacement OHC (likely DOHC) turbocharged V8 that revs to 10k that makes an excess of 400hp? Sounds way too good to be true but if its true then hell yeah sign me up I'll get rid of my Accord!

      The 5.5 is plausable because that is what they are racing now in ALMS GT. At the same time, that engine is restricted - 450hp or so. Ron Fellows indicated that uncorked, it could touch 600. Now, that would NOT be smog legal, and race engines are seriously overbuilt for the purpose at hand. So detuning and federalizing leaves the 5.5 at a strong 435 or so for the street. And it would still get good MPG. And this raises yet another question - do street cars REALLY need 600hp? I am not so sure, except for bragging rights and bench racing. I have a 92 Vette with a 300hp LT1 and it motivates just fine; I do want more, but not twice as much. 400 or so would be perfect. Now.. a 3 litre DOHC TT... unless GM is committed to doing an all new northstar, then I would be surprised. They won't make an engine EXCLUSIVELY for Corvette anymore. They can't afford it. This is why the LS9 is seen in other guises in the CTS-V and ZL1. Ammortizing cost across the range is the fancy way of saying it. What is interesting, a motor of that nature would be entirely against the Corvette model, but would work great in a mid-engine application, so if GM really is planning a 2 car C7 - the conventional front engine/RWD coupe AND a midengine supercar, both under the banner of Corvette - then it makes some sense. The reason why the current DOHC V6 isn't in the C6 is height, weight and cost! As it stands, the V6 is just too tall to fit. And to get the power up there, think TT, it gets really pricy. Also, you get the stigma of a V6 and the strange exhaust note. A howling 3 litre V8 would sound a lot better. Pushrods are not required, as far as I am concerned. The 1990-95 ZR1 proved that. What a great engine that was... fabulous! Oh, and it was the daddy to the Northstar. It should be noted that Ferrari DID do the 288 GTO and the F40 off of a nominal 3 litre V8. The GTO hit 400 hp and the F40 did 478hp. Impressive at any time, really. Otherwise, wait and see. A lot of this is conjecture, and the Corvette world really starts to get buzzing with false profits during new model release time. After the discussion with Tadge Juechter during the 12 Hours of Sebring, it was decided, by the group in attendance, that the C7 was going to be smaller, evolutionary and diesel powered... oh, and with a better interior! So make your predictions and place your bets... cause I ain't gonna, this is the third new Corvette release I have been through since I became a Corvette geek, and I am not predicting anymore!

      The Mp4-12C's 3.8L turbo V-8 makes 592 so why not?

      10000RPM in a turbo V8! Sounds good to me.

      Nope. GM is NOT going to spend for the development of a 3L V8 with DOHC just for a Corvette run. They already dropped the new Northstar DOHC V8 and no new sedans are supposed to get V8s. The current V8 is hi-tech and highly efficient. A new iteration, slightly smaller capacity might well equal today's power and get 30 mpg on the highway. If Corvette want a smaller engine in their range a budget model with the V8 from the CTS would be an idea. Corvettes provide a different experience to ultra high reving European sportscars and in the real world they provide equal grunt and better low range torque on the road. There is NO WAY Corvette are going to turn their backs on their loyal customers and become a boring "me too".

      Good idea, Would make a good performance engine for other chevs and buick. I love small block Chevs but a modern Malibu, Monte Carlo, Regal or Riviara dosent really need 500 horpower. Or the size and strenght needed to house it.

      When has GM powertrain put out a dud of a performance motor in the last several years? Don't count them out no matter how many cylinders or which type of breathing is used.
