2014 Engine Specs LT1
The next generation C7 Corvette LT1 6.2 liter base engine is revealed with an increase in horsepower and several technological advancements from the previous LS series found in the C6. The technological edge takes the next Corvette to a level of performance and efficiency that has never been seen before.
Without a doubt the Corvette will be the greenest sports car on the market. This is done without batteries or electric motors but good old fasion gasoline! Absolutly no loss in performance is realized with the most important advancement in engine technology ever put in a Corvette.
Active Fuel Managment is the system Chevrolet is calling the system that controls the GenV engine switching from a V8 to a V4. This system deactivates under light engine load conditions 4 cylinders to save fuel. Great pains were spent by GM engineers to maintain the sound of the V8 under all important areas Corvette lovers expect to hear.
The 450 hp and 450 ft lbs of torque is an improvement of 20 hp and 24 ft lbs of torque over the LS3 base Corvette engine. Enough of an increase to propel the C7 performance specs for 0-60 to under 4 seconds.
