Chevrolet introduces 5th generation LT1 small block V8

Chevrolet has unveiled the company’s new LT1 small block V8 engine, which will find its way into the 2014 Corvette.

The generation five V8 features direct-injection, continuously variable valve timing and an 11.5:1 compression ratio. There’s also a “Runners in a Box” intake manifold, a variable-displacement oil pump and a specially designed exhaust system.

Chevrolet estimates the new mill will produce approximately 336kW (450hp) and 609Nm (450 lb-ft) of torque. 0-60mph (98km/h) should be dispatched in less than 4 seconds in the new Corvette.

Like all new powerplants, fuel efficiency is the key and the new LT1 is said to be more frugal than the outgoing LS3 V8, thanks to cylinder-deactivation technology. The LT1 will automatically shut down four cylinders under low load, allowing the Corvette to return an estimated 26+ mpg US (9.05L/100km).

In Australia, the new engine may eventually power the range topping F-Series HSVs due out next year.
