Praga Bohema

Although the Bohema is heavily oriented towards track performance, it maintains several features that somewhat preserve its useability as a road car, such as storage bins located at the rear wheel arches and Alcantara stitching in the interior.[3][4] British firm Litchfield Engineering has also made several modifications to the engine, which is shared with the Nissan GT-R. The VR38DETT's wet sump oil system has been replaced with a dry sump, the turbochargers have been replaced with Litchfield's own, bringing power and torque up to 700 PS (690 hp; 515 kW) at 6,000 rpm and 724 N⋅m (534 lb⋅ft) between 3,000 rpm and 5,000 rpm, and is paired to a titanium exhaust at the rear.[5]

Power is sent through the rear wheels via a 6-speed Hewland sequential manual transmission, to tyres shod in Pirelli Trofeo R (305/30 ZR19 102Y rear, 245/40 ZR18 97Y front). This arrangement allows for the interchangeability of road tyres with track-only Michelin slicks, which are the same size.[6] The mechanical grip is complemented by the radical exterior design that Praga claims will provide 900 kg (1,984 lb) of downforce at 250 km/h (160 mph).[6] Extensive use of carbon fibre throughout the car including its chassis gives it a kerb weight of just under 1,000 kg (2,205 lb).[7]
