As with most Corvette engines since 1955 it is an overhead valve V8 - a layout that is claimed to be lighter and more compact than rival, twin overhead cam units. Displacement is 6.2 litres with an initial power output of 450hp - and maximum torque of 610Nm. As installed in the Corvette it is claimed to give 0-100km/h in about four seconds along with an estimated 26mpg on the American EPA drive cycle.
The aluminium block and heads are new, though the architecture is based on the Generation 4 V8. Within the heads are combustion chambers designed to give an 11.5:1 compression ratio.
Final details of the Corvette LT1 V8 will be released next year, while the car itself gets its world debut at the Detroit Auto Show in January.
