There has been a lot of talk on the C-7 forum about the use of a twin turbo V-6 in future Corvettes. The talk is also associated with the "C-8". Here is an announcement about a twin turbo V-6 GM is reportedly developing which could be a candidate engine. Notice that the verson showcased in the Camero SEMA car was producing 425HP.


"According to GM engineering sources, GM is currently working on a twin-turbo 3.0L V6. Development on the new engine is so far along that it has a RPO code of “LF3.” The naturally aspirated 3.0L debuted in several 2010 products with direct injection and has the code “LF1.”

GMI was not able to obtain projected power ratings on the new engine, however output is very application specific under new SAE testing rules. Sources did say to expect the engine to rival Ford’s EcoBoost 3.5L.

The engine’s introduction is expected in late 2011 or early 2012 in the Cadillac XTS. Sources also state that GM is looking to use the engine in the Cadillac ATS and possibly even the next Chevrolet Camaro. Cadillac has historically always debuted new variants of the High-Feature V6 lineup, so it comes as no surprise that the XTS is the likely to pioneer the 3.0L twin-turbo.

Most rumors surrounding the potential of a turbocharged V6 out of GM have centered on the company’s 3.6L V6. A couple of years ago GMI was told that GM had twin-turbo 3.6L V6’s in development that were generating as much as 435 horsepower. Information regarding the potential of a blown 3.6L silenced for years until GM showed a 3.6L twin-turbo V6-powered Camaro show car at the 2009 SEMA show. The Camaro show car was generating 425 horsepower."

One other engine, in fact entire car, that almost sounds like a C-8 is the McLaren MP12-4C. I wonder if the GM people were looking at that car and saying "that would make a neat C-8"? "What is interesting is that this engine is a small turbocharged V-8. Dubbed the M838T, it is twin-turbocharged V8 with a displacement of 3.8 litre. Although no exact performance figures are known yet, it is expected to produce around 600 bhp and 600 Nm of torque, 80% of which is available as low down as 2000 rpm. The V8 is also incredibly efficient as it emits less CO2 per bhp produced than any other internal combustion engines available today, including the ones used in 'green' hybrids. The engine is mated to a dual-clutch, seven-speed gearbox."

I wonder again, if a small turbo charged engine would be more acceptable to Corvette fans if it was a V-8?

If they over-engineer it like BMW did with the n54 engine ( the one found in the BMW 135/335) it will be a good thing. Those BMW guys can pick up nearly an extra 100whp with intake/exhaust/ecu upgrades.
