2014 Corvette will Deliver More Power, Better Fuel Efficiency

General Motors Company says the 2014 Chevrolet Corvette will feature a new 6.2-liter that will be more powerful and more fuel efficient than the engine in the current model.

The seventh generation Corvette will arrive in dealer showrooms during the fourth quarter of 2013, and will be powered by the LT1 overhead valve, 450 hp short block engine that will deliver 450 pounds-feet of torque.  The current base model Corvette is powered by a 6.2-liter small block 430 hp engine capable of 424 pounds-feet of torque.

GM says the new Corvette will also be more fuel efficient than the current engine, but have 0 to 60 mph acceleration of less than four seconds.

The automaker reportedly considered a number of engine options, including a twin turbo V-6, before deciding to improve the small block V-8 according to executive chief engineer Tadge Juechter.  One reason for the decision was the high degree of loyalty Corvette aficionados have for the small block V-8. Juechter said, “When you talk to Corvette customers, the most important part of the car for them is the engine. They want their Corvette to have a V-8.”

The redesigned fifth-generation small block engine will feature direct fuel injection, continuously variable valve timing and cylinder deactivation. Cylinder deactivation automatically idles four of the engine’s eight cylinders in certain situations to improve fuel efficiency. Direct fuel injection also helps to increase fuel efficiency by more precisely controlling the air-to-fuel mixture.

GM’s small block chief engineer Jordan Lee said, “Every drop of fuel converted to energy. By improving efficiency, you get power, you get torque and you get fuel economy.”

The new small block engine will also be more responsive than the current version when driving at slower speeds, and will deliver torque comparable to the Corvette Z06’s 7.0-liter engine.

GM plans to use the new short block engine in future pickup trucks and SUVs beginning as soon as next summer. The current Corvette’s fourth-generation small block engine is approximately 30 pounds lighter than the new LT1, and has been in service since 2005. The new LT1 small block engine will be built at GM’s engine plant located in Tonawada, New York.
