Praga is one of the Czech Republic’s best-kept automotive secrets with over 100 years of history and countless years of modern racing experience. Now it will bring its expertise on the world’s racetracks to public roads with the highly limited Bohema supercar.
Powered by the 3.8-litre twin-turbocharged V6 from a Nissan GT-R, the engine goes straight from Japan to the UK to be modified by Litchfield. The tuners strip the engines and convert them to dry-sump, making them smaller, allowing them to sit lower in the car and avoiding the risk of oil bumps during high-speed cornering.
The tuner also adds its own turbochargers to the engine to make it even more reliable, boosting power to 700 hp (522 kW/710 PS) at 6,800 rpm and 534 lb-ft (724 Nm) of torque between 3,000 and 5,000 rpm. rpm. Titanium exhausts make the engine sound better and power is routed through a six-speed Hewland sequential gearbox. The robotic clutch gives it a semi-automatic mode, for more comfortable road cruising.

The motor and gearbox are mounted independently of the carbon fiber monocoque designed with Praga’s years of track experience, to avoid annoying resonant vibrations in the form of a subwoofer.
Attached to the monocoque are carbon fiber body panels designed entirely in-house. The engineering and design teams worked hand-in-hand on an F1 team’s wind tunnel to ensure that the car not only looks good, but can also deliver 900kg of downforce at 250km/h.
That’s almost the full weight of the car in downforce. Thanks to the carbon construction, chosen specifically to keep the pounds down, the car weighs less than 1,000 kg (2,204 lbs) wet. According to the manufacturer, it can reach 100 km/h (62 mph) from a standstill in less than 2.3 seconds, while capping out at a reasonable 299 km/h (186 mph), which Praga says is the highest speed attainable on most race tracks.
Like many race cars, the Praga Bohema will have horizontally mounted pushrod operated adjustable dampers. They mate to 18-inch front and 19-inch rear center-lock wheels. They cover 380mm carbon-ceramic discs with six-piston calipers. All in all, Praga engineers were able to keep the unsprung mass down to just 396.8 lbs (180 kg), meaning the ride can remain smooth enough for the road without resorting to a heavy adaptive suspension system.
However, to ensure he is as good on the track as he is on the road, Praga turned to his old friend, former F1 driver and current IndyCar ace, Romain Grosjean. Ultimately, the automaker says it is targeting GT3 race car lap times for this supercar.
“I was amazed by the Bohema’s great performance on the track, its accessibility on the road and the ease of transition between the two,” said Grosjean. “Praga really lived up to my challenge! On the road you drive smoothly, the car eliminates the bumps, you can have a chat with the passenger and everything is calm and OK. Then just switch the focus and you’re on track.”
Inside, meanwhile, Praga said it was important to design a car comfortable enough for large adults. It features reclining seats, steering wheel, pedals and more. It has storage space for your smartphone and water bottles, as well as air conditioning for warmer days. Praga says the cockpit design was inspired by the aviation and racing divisions, which explains the extensive use of Alcantara.
In all, Praga will build just 89 Bohemas to celebrate the 89th anniversary of the Praga Alfa’s victory in the 1933 Czechoslovakia 1,000-mile road race. Prices for the supercar start at $1.31 million and production is expected to begin in the Czech Republic. , in the second half of 2023. Once production is up and running, it hopes to build 20 Bohemas per year. The company is now taking orders and is in talks for sales in the US, UK, Germany, Japan, Hong Kong, Australia and other supercar markets.
