What is the 2014 Corvette LT1 6.2L Engine

New Engine, New Promises

On October 24th, GM revealed the LT1, the 5th generation in its small block engine line. The new V-8 has a 6.2 liter displacement, higher fuel efficiency than previous engines, and a 450-horsepower capacity. The engine will appear in the 2014 Corvette that goes on sale next year, as well as in different versions in the Chevrolet Silverado or the GMC Sierra, to name a few.


What’s new in the LT1?


First of all, the engine now features direct injection, continuously variable valve timing, and cylinder deactivation. The direct injection setup is isolated rather than rigidly mounted in an effort to reduce the normal direct injection issue of noise and vibration. The engine can also temporarily deactivate four of the cylinders.


In addition, the compression ratio, or the ratio of the volume of the cylinder with the piston fully lowered to the volume with the piston fully raised, is 11.5:1. This makes for a remarkably efficient and powerful engine. Also, while such a ratio would normally require premium fuel, careful engineering of the engine makes premium fuel optional, although suggested.


Basically, the entire engine has received a makeover, making it more powerful, more fuel efficient, keeping it compact, and able to get a Corvette from 0 to 60 in under 4 seconds. It’s an engine GM is proud of.
