First historical design sketches of this sports car were made at V.

The current production capacity at the new factory is limited to only 25 units per year to guarantee a high level of precision in the custom production process.

The body was handcrafted of aluminium with a tubular space frame chassis. The engine was an aluminium V8 5967 ccm developing 405 hp (302 kW) at 6000 rpm, and 542 Nm at 4400 rpm. It had a 6-speed manual gearbox. The brakes were Brembo 4-pistons.

The Leopard 6 Liters Roadster was officially launched about April 2005 in Paris, France, first units to hit the market were produced about late 2005, now selling for about €130,000. Leopard is claiming the title of the most expensive ever commercially produced Polish vehicle. The total number of manufactured units currently stands about 25 and is to be limited to maximum of 200 to retain the exclusive status. The manufacturer is preparing a new, stronger, Leopard Coupe model.
