Motor Trend: C7 Corvette to Debut with New 5.5L 440 hp V8 Powerplant

C7 Corvette to Debut with New 5.5L 440 hp V8 Powerplant

Sources within GM have told Motor Trend that the C7 Corvette will be one of the first cars to feature the next-generation small block V8. General Motors recently announced its investment of $890 million to develop and manufacture the powerplant. The new V8 will feature aluminum blocks and heads, direct injection and a new combustion system.

Motor Trend says the new V8 will come in at 5.5 liters with a target output of about 440 horsepower. The current Corvette’s LS3 engine is a 6.2 liter engine with 436 horsepower.

The new 5.5 liter V8 will retain its traditional overhead-valve layout ensuring compact dimensions and lower manufacturing costs. Motor Trend says prototype engines are already running on test mules in Detroit.

This is no big surprise as the Corvette Racing team recently moved from a 7.0 liter to a 5.5 liter by destroking the engine. Program Manager Doug Fehan says that at 5.5 liters, the C6.Rs are able to run a larger restrictor which produces the amount of torque that current Corvette owners are accustomed too.

    Huh? How is the torque of a C6.R in any way related to what current Corvette owners expect? It’s not like production Corvettes will now be able to run a larger restriction plate, thanks to the smaller displacement. Thankfully ALMS field-leveling rules do not apply to road cars, or we’d all be driving huge-ass diesels.

  2. Hi Bob.

    I remember Fehan talking about the current 5.5L engine in the GT2 Corvette either at Sebring or the Bash at the Museum. I mentioned it in the article as the racing program is the defacto test bed for Corvette and especially when we are talking about similar engine displacements. Obviously Corvette owners are concerned about going to smaller engines as to many it equals less power. Fehan addresses the 5.5L as having the torque and the deep V8 sound Corvette fans are accustomed to.

  3. Smaller engine huh. Well, that does not sound like something I’m attracted to. Less is more? >Don’t think so! But I trust Corvette. They’ve never let me down, especially as of late. So I’ll follow.
