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.

Ah yes, the classic small block Chevy. No other engine in history carries as much nostalgia and General Motors looks poised to push its mouse motor well into the future by adding new technologies designed to clean up the mill's emissions and improve fuel mileage. Expect these engines to show up in applications from sportscars like the Camaro and Corvette to pickup trucks and SUVs.

According to GM, all of its next-generation small block V8s will use aluminum engine blocks in addition to being E85 compatible. We can also expect to see direct injection added to the small block's repertoire for improved efficiency and power production. Finally, the combustion chambers will see a redesign that will promote fuel efficiency.

Naturally, an update to an existing engine line requires a suitable investment, and this one is no different. GM will be investing nearly $900 million and will add or retain more than 1,600 jobs in Tonawanda, NY; St. Catherines, Ontario; Defiance, Ohio; Bedford, Indiana and Bay City, Michigan. More details can be found in the press release after the break.
