The Corvette C5 Z06 is a high performance C5 released in 2001 and discontinued in 2004 with 28,388 units manufactured. The C5 Z06 was treated by Chevrolet as the spiritual successor to the C4 ZR-1 model developed with Lotus and a re-release of the high-performance Z06 brand that hadn't been used since the C2 Z06. It was also fitted with several refinements compared to the standard C5. This included flat underside body panels, rear air scoops, side air inlets, front screened air inlets, an interior tachometer and red painted brake calipers.
