GM Announces the LT1 – Motor Trend

Big news out of General Motors today with the announcement of the new LT1 V8 that will be replacing the venerable LSx family of engines in the next Corvette. The 6.2 liter V8 makes 450 horsepower and 450 ft-lbs of torque and is projected to get 26 mpg in the C7 thanks to cylinder deactivation and direct injection. Interestingly enough, GM was able to improve the gas mileage by increasing the displacement, not reducing it. The larger 6.2 liter engine means a 3.1 liter V4 when the engine is running in cylinder deactivation mode. The V4 makes enough power that it can be used more often in the engine’s duty cycle which reduced the overall consumption of the engine. V8 power only when you need it. Very clever. Head over to Motor Trend’s article to read up on all of the details with pictures and dyno videos of the new engine.
