A successor to the ZR-1 made its debut in 2001 as the Z06, giving a nod to the high-performance Z06 version of the C2 Corvette of the 1960s. The Z06 uses a tuned version of the standard LS1 engine (designated the LS6), with a higher power output of 385 hp (390 PS; 287 kW), later bumped to 405 hp (411 PS; 302 kW) starting in 2002.
For competition, race customers had a range of options available to them including the N03 36-Gallon Fuel Tank, closer rear axle ratios and the C48 Heater/Defroster Delete (-100). Most cars equipped like this came with either L78 or the L84 with Ram-Jet Fuel Injection.
