Road-legal racing car
Czech automaker Praga has unveiled its new hypercar Bohema for the first time. It is currently in the final stages of development and is expected to go on sale next year.
The mid-engine, carbon tube, carbon body Bohema will be the first full-fledged road car (a model that can run on public roads) since 1947 for Praga, which has a history of 115 years. Its design has been greatly influenced by the circuit-only car “R1” that develops one-make races.
The Bohema and the R1 have very little in common and are two new cars built from the ground up. In order to run properly on public roads, the overall size is close to supercars such as the Ferrari 296 GTB. The cockpit is a tight structure, but it can accommodate the driver and passenger reasonably comfortably. There is a 100L luggage space on the side.
It took two years to establish its performance on the circuit, such as using the F1 team’s wind tunnel equipment to refine its aerodynamic characteristics. We are currently in the final stages of ensuring comfort.
Also, instead of directly fixing the powertrain, fixing it to the central structure via a subframe made of chromium molybdenum steel is also an important factor in view of driving on public roads.
An automatic clutch sequential transmission is also under development and will be finalized by characterizing the pushrod suspension with manually adjustable Öhlins dampers.

However, it makes major concessions when it comes to usability and comfort, with speed being the Bohema’s deepest pursuit.
The target vehicle weight is 982kg, and it is designed to emphasize circuit driving, such as generating a maximum of 900kg of downforce at 240km/h.
The powertrain is equipped with the same 3.8L V6 twin turbo as the Nissan GT-R, but the maximum output has been increased to 700ps. In addition, a dry sump system was adopted for oil circulation to cope with the high lateral loads that occur during circuit driving, and the height of the engine was also successfully lowered. Also, the Bohema is a midship rear-wheel drive.
In addition, Nissan’s engine support system for Praga was established with the cooperation of British tuning company Richfield, which is also known for GT-R tuning cars. According to chief engineer Jan Martinek, Nissan’s 3.8-liter V6 and Audi’s 5.2-liter V10 were among the engine options, but the latter didn’t expect continued support from the manufacturer, so Nissan was ultimately chosen. It is said that
Production of the Bohema will take place at the same Czech factory as the R1, under the direction of former Ford WRC driver Roman Cresta.
Prices will start at £1.32 million in the UK.
