Design engineer Zbyslaw Szwaj built 7 units of the Gepard Series 1 roadster in the years 1990-95. In July 2000 he teamed up with partners from Sweden to establish a new company – Leopard Automobile-Mielec. In November 2003 they presented the prototype of the avant-garde, retro-style Leopard 6 Litre Roadster, which went into production in 2005. Its aluminum body houses a Chevrolet 6.0-liter 405-430 hp V8 engine, which develops an electronically-limited top speed of 250 km/h and propels from 0 to 100 in 4.0 seconds.
