Chevrolet 50th Anniversary Corvette Stingray Concept – Click above for high-res image gallery

According to Motor Trend, which is citing unnamed sources within General Motors, the next-generation Corvette will come with a brand-new engine. Despite rumors to the contrary, it seems that Chevrolet's halo vehicle will continue using its trademark V8 engine and not a V6. Still, the C7's powerplant will be downsized from its current 6.2 or 7.0 liters.

It's likely that this new engine will be the first application of GM's next-gen small block family, and we'd expect it to sport direct injection, E85 capability and a new combustion system design. One thing not to expect, though: overhead cams. You can bank on the fact that The General will stick to its tried-and-true overhead valve design, which serves to lower manufacturing costs and allows for comparatively small overall engine dimensions.

All of these technologies should make the venerable V8 more fuel efficient and cleaner, but also sufficiently powerful to uphold its sportscar heritage. In fact, Motor Trend reports that the C7's V8 will displace 5.5 liters while hammering out 440 horsepower. Though that significantly smaller in displacement, the power figure would actually be up from the current 430 ponies. We can hardly wait... but we'll have to anyway. We don't expect the next Corvette to bow before 2012 at the earliest.

      it looks sweet to me from the drawing, I don't see nothing wrong with the new 5.5 liter, being a OHV V8, esp if that 5.5 OHV V8 makes 440 hp, then if the mpg is the same as now in the current vette or if not better then what's wrong with a new modern OHV V8.
      haha I say do a base model too with the v6 from the camaro with even bertter mpg ..

      If VVT or even just cam phasing can be added affordably, efficiently and without adding a lot of weight/size, I'd love to see it.

      Otherwise, I sure hope this has a new block with new bore centers, because reducing the displacement on an LS just by deboring it doesn't make it smaller and actually makes it heavier, destroking it would make it only very slightly smaller and lighter. So why bother with that?
        • 4 Years Ago
        Wouldn't you need multiple block castings? The cylinder walls would be to thin if you bore it to much. Of course that is me thinking that they will continue to produce higher displacement engines(Z06/ZR1) instead of forced induction.
        • 4 Years Ago
        The Escalade engine has VVT... it's more or less an LS2.

        • 4 Years Ago
        The Escalade has VCT, not VVT.
      • 4 Years Ago
      I'd like the base LS3 to get more power for bragging rights as a final sendoff
      for the C6. Sales are in the toilet and we've got 2 more years at least until the C7 arrives.

      I'm not holding my breath though.
      • 4 Years Ago
      Let's hope it doesn't look like that, it's already dated.
      • 4 Years Ago
      Well that explains the link between their GT2 cars. When they were racing in Le Mans, I was thinking.. 5.5L, wth? Guess they're already hardcore-testing their motors in race applications prior to the street version.
        • 4 Years Ago
        Wrong the ALMS motor is a destroked 6.2
      • 4 Years Ago
      I assume this engine is based off the GT2 car's 5.5 liter for the ALMS series. That's badass... I love seeing race technology make it to the street!!
        • 4 Years Ago
        actually the 5.5L is just a de stroked 6.2 they had to do it for this years regulations. so just think about it. they are doing that well on a stop gap motor.
      • 4 Years Ago
      I wonder how torque output will look like and where hp and tq curves will look like as well with the smaller displacement engine.
      • 4 Years Ago
      A smaller but more powerful engine is a step in the right direction. Now if they can just fix that front end....
      • 4 Years Ago
      Dam the first vette I wanted since my stingray.

      • 4 Years Ago
      I welcome the change. It's good to see a company that was known for being behind the times embrace technology as it has in the last few years.
        • 4 Years Ago
        Their ecotecs and v6's are already mostly all DI, so I don't see how they're far behind the times. Everyone points to the OHV design, but they tried a DOHC V8 when they were working on the last generation of small block, but decided that they liked the OHV design better.

        @ spin cycle

        You gotta be kidding me if you think that GM has been ahead of the pack when it comes to technology for all their engines.

        They have only recently gotten around to implementing variable valve tech into their mass-market engines, something that has been around since the '80s from the Japanese. Hell, up until just a couple of years ago, they were still trying to pimp out those awful 3600/3800-series engines onto consumers.
        Have they been improving? Absolutely. The 2L DI turbo engines in the Sky/Solstice were damn impressive. And they have been integrating DI into most or all of their new engines lately, but the last 2 or 3 years is not going to erase 20 or 30 years of being behind the times.

        GM up until recently has been a sea of mediocrity broken up once in a while with an island or two of brilliance. Lets not confuse the Vette as being the "typical" GM car, because it most definitely is not.
        • 4 Years Ago
        Hazdaz:
        I said on integrating DI. Do you disagree?

        The Japanese didn't debut VVT in the US until the VERY late 80s. Mass market it didn't come around until the Civic in 1990ish. Of course, while you are blasting GM's engine for not being high-tech, you don't bother mentioning GM had distributorless ignition in 1984 (1986 for non-hi-po models) and Honda shipped their "high-tech" Civics and Integras with VTEC with distributors and points until 1998 at least.

        I don't think you mean the 3600/3800 series. There's no such thing that I know. The 3800 was the Buick V6 and was an excellent motor. I was a tank, although mpg wasn't great. The 3.4L was another motor, it is the 60-degree V6. I never liked it (or as the 3.1L or 2.8L as seen in the Cimmaron).
        • 4 Years Ago
        You're insane. The LS engines are already very high tech, and GM has been AHEAD of most companies on adopting DI and right in the pack on turbos.
        • 4 Years Ago
        @ spin cycle

        No, I AGREE with you on the DI issue. And I do agree with you that for the last couple of years they have indeed stepped it up, but the way your previous post made it sound was that they have been at the forefront of engine technology since forever and that is simply not the case. And I don't care that technology like VVT was introduced in the late 80s or more mass-market in the early 90s... that still 20 years ago and it took GM WAY the hell too long to adopt that tech. And most of GM's first attempts was through their Isuzu-partner and not actually designed inhouse.

        From the '70s up until the '00s, there are few technologies (especially engine technologies) that they have actually introduced... and the few times they did try to innovate, they were usually 1/2-baked attempts and never gave the technology time to improve - two very real examples were the god awful Olds diesel engines, and the original Cadillac V8-6-4 engines.
        • 4 Years Ago
        Completely agree with that.

        Unfortunately it seems that they had to be prodded into doing it. But whatever. At this point, I want to see the floorgates open up and see what a reinvigorated GM with an emphasis on engineering will be able to do.
        • 4 Years Ago
        ...Which is exactly why I said "in the last few years". Yes all of the advancements you have mentioned have been great, but they are all fairly recent. To illustrate my point, I feel like I should mention the Cobalt (the SS is fast but do you want it?), Colorado, (the thankfully dead) Trailblazer, Impala, the last Malibu, the current Malibu Hybrid, the last Equinox, (in my opinion) the Silverado, and the Uplander. The LZ and LX V6 engines are crap, and those inline 5s are just the worst. Now think of the much better Cruze, Traverse, new Equinox, and (non-hybrid) Malibu. The difference speaks for itself. Plus, I'm pumped for the Volt. It may not be an enthusiasts dream, but I can't help but drool over the potential of the technology.

        Sure, the Corvette is always impressive, but I was speaking to the brand as a whole. By the way, I'm going to make a leap here and say that--assuming it's NA and they don't sacrifice fuel economy or torque--a 5.5L V8 putting out 440hp probably IS more high tech than a 6.2L V8 making 430.
      • 4 Years Ago
      Should be interesting to see what they do with the ohv design to get the power and efficiency they want out of it. Bring It GM!
        • 4 Years Ago
        Whatever Chevy ends up doing, they will fil miserably in the end.

        History will repeat itself.
        • 4 Years Ago
        @ Alex

        No, I think you misunderstood him.
        This new Vette will be a massive "fil." Like I guess you can "fil" it with tons of groceries or something since it will have a large trunk area. Or maybe he was talking about his buddy "Fil" was going to buy one.

        I guess.

        I mean all those make more sense than if he was trying to imply that it would somehow "fail." Because that would be a rather idiotic comment.

        I love the Chevy small block it is honestly probably one of the best engines in industry, its simple, very light weight, makes massive power and torque. I hope GM is able to add VVT ,DI, variable displacement, and stop/start technology. God that would be insane, the Corvette already gets great mileage, with technologies like that you could easily see a 15 to 20% increase in mileage. I'll take one in Jetstream Blue, Thanks!
        • 4 Years Ago
        @John P - agreed. i was amazed to find a small block vette engine nestled in a competitors e30 last weekend, more amazed to find it weighed only a few dozen pounds more than the straight six. wow!
        • 4 Years Ago
        @sloturbo GM won't go mid engine because they have proven the performance they can get in the current platform but most of all I don't think they will sacrifice the utility of the fast back design. Unlike most high performance cars you can actually carry more than a single golf club...by golly you can fit a few whole sets!

        My point is there is no need and it is a great selling point for them now. This is just my opinion. All for the other additions.
        • 4 Years Ago
        will this be designed in Korea?
        • 4 Years Ago
        I think GM ought to GO BIG or GO HOME... thinking mid-engine, maybe AWD, some use of electric motors, outside looks great, but inside is often where GM falls down. Go for an upset of a R8 or Lambo, or even a 911 turbo.
        • 4 Years Ago
        btw that was sarcasm... sometimes people around here have a hard time figuring that out.
        • 4 Years Ago
        @The Langer Monger!, yes because the Corvette has been a massive failure for Chevy.
        • 4 Years Ago
        Because designed "in Korea" implies something totally different then the truth which is designed "in Detroit, by an American of foreign ancestry."
        • 4 Years Ago
        So base 5.5?

        I guess they're saving the 350cid 5.7 for an uprated model, with forced air for the top..
        • 4 Years Ago
        @Paul

        The Corvette is already shorter than a 911 and only weighs 3200lbs. How small do you want it? I'm all for light weight, but it's already quite light. Hard to make it lighter while keeping it affordable.
        • 4 Years Ago
        I think a smaller V8 with a small electrical engine could be a potent mixture, giving the vette great quarter speeds with the electrical assist
        • 4 Years Ago
        Let's just hope it's smaller, lighter and has a halfway decent interior. I've always loved Corvettes but I'd never own one -- just too cartoonish and cheap feeling. If they can reel in the styling and build some quality into it, I might just be there...
        • 4 Years Ago
        Wow, why downrate michiganboy? The S197 Mustang and current-gen Camaro were both penned by Korean designers. If you like the looks of those--as I do--you'll just have to admit to yourself that those Koreans can damn well draw them some muscle cars.

        I see no problem with continuing ohv for the 'Vette V8. The LS series has been absolutely some of the most intoxicating engines of their time, and the next one will no doubt continue the tradition.

        I do hope that the brief for the next 'Vette includes lighter weight, better body rigidity, a higher-quality interior, and the long-awaited demise of the characteristic 'Vette plastic resin smell... but all of those things cost money, and you can't have everything at the 'Vette's relative bargain price point.
        • 4 Years Ago
        PJ -

        " The S197 Mustang and current-gen Camaro were both penned by Korean designers"

        The man who designed the S197 Mustang is a Vietnamese born American, who lives in Michigan. His name is Hau Thai-Tang.
      • 4 Years Ago
      That should be the Camaro SS motor as well.
        • 4 Years Ago
        With that kind of power efficiency, the next Camaro could start with a 350 hp 4.4l V-8, with a 400 hp 5.0l for the SS.

        Then shrink the next-gen Camaro chassis a tad, add a little more lightness, pinch off some bloat while they're at it.
        • 4 Years Ago
        John, I hear the next Camaro is going to get the new Caddy ATS's RWD architecture..so it should *hopefully* shrink quite a bit and add a couple hundred pounds of lightness.
