Totally New Corvette DOHC Twin-Turbo LT7 V8 Is Revealed

Corroborating with pictures that surfaced on the internet last week, the next-generation Corvette will be receiving a new DOHC twin-turbo V8 that’s likely to birth GM’s next-generation V8 architecture. Displacement still remains a mystery, and will likely remain shrouded in secrecy until launch. However, there are alleged rumblings a 4.0-liter motor for racing purposes, along with perpetual rumors the Corvette will gain a 5.5-liter V8 pilfered from Corvette Racing.

I hope they make a large displacement, non-boosted version of the mid-engined Corvette.

Been reported in various enthusiast magazines that mid-engine Corvette will come with three engine choices...likely natural aspirated base V8 from C7, double over head cam and boosted double overhead cam. Time will tell.

While some supposedly intelligent people will say (because they read it somewhere) there's no difference between a naturally aspirated engine and a boosted one there is a difference, but the people who cannot tell the difference are probably better suited to driving icky, overweight crossovers anyway.

You know, although some people complain about turbochargers, the Porsche 911 Turbo S has a 3.8L engine that delivers 580 hp and a ton of torque. Drivers say the engine is brilliant and responsive, rather than "laggy". So I don't care what tech a manufacturer employs in their engine, as long as it feels great and benefits me.

Knowing that Porsche can create great turbocharged performance engines, I suspect GM can pull this off nicely, too.

Looking at the photo and the stubby exhaust tips and exhaust piping, this would be a configuration for a mid/rear engine application. Frame members supporting the engine appearing at an odd angle is also interesting.

You can also see in the photo that the turbo exhaust piping is routed outside the engine block and the turbos themselves are beside the engine. This is unlike motors where the turbo(s) are in the V of the engine. If this is for the mid-engined C8, it will be a very, very wide car at the rear.
