Praga is among the Czech Republic’s best-kept automotive secrets and techniques with greater than 100 years of historical past, and numerous years of recent racing expertise. Now, it would put its experience on the racetracks of the world onto public roads with the extremely restricted Bohema supercar.
Powered by the three.8-liter, twin-turbocharged V6 from a Nissan GT-R, the engine goes straight from Japan to the U.Okay. to be modified by Litchfield. The tuners strip the engines and convert them to dry sump, which makes them smaller, permitting them to take a seat decrease within the automobile, and prevents the chance of oil surges below high-speed cornering.
The tuner additionally provides its personal turbos to the engine to make it much more dependable, and push horsepower ranges as much as 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. Titanium exhausts make the engine sound higher, and the ability is routed via a Hewland sequential gearbox. Its robotic clutch provides it a semi-automatic mode, for extra snug on-road cruising.

The engine and gearbox are mounted independently of the carbon fiber monocoque that was designed with Praga’s years of on-track expertise, to stop annoying sub-woofer-style resonance vibrations.
To the monocoque, carbon fiber physique panels are hooked up that had been designed completely in-house. The engineering and design groups labored hand-in-hand at an F1 workforce’s wind tunnel to make sure that the automobile not solely appears good, however can ship 1,984 lbs (900 kg) of downforce at 155 mph (250 km/h).
That’s practically your entire weight of the automobile in downforce. Because of its carbon development, which was particularly chosen to assist it preserve the kilos down, the automobile weighs in at lower than 1,000 kg (2,204 lbs) moist. Its high pace, in the meantime, is a wise 186 mph (299 km/h), which Praga claims is the very best pace realistically achievable on most racetracks.
Like many racecars, the Praga Bohema could have horizontally-mounted pushrod-operated, adjustable dampers. They connect with center-locking wheels which are 18-inches on the entrance and 19-inches on the again. They cowl 380 mm carbon ceramic discs with six-piston calipers. All in, Praga’s engineers had been in a position to preserve unsprung mass restricted to only 396.8 lbs (180 kg), which signifies that the journey can stay supple sufficient for the street with out resorting to a heavy adaptive suspension system.
To make sure that it’s pretty much as good on observe as it’s on the street, although, Praga turned to its previous pal, former F1 driver and present IndyCar ace, Romain Grosjean. In the end, the automaker says it’s concentrating on GT3 race automobile lap occasions for this supercar.
“I used to be astonished by the Bohema’s superb efficiency on observe, its accessibility on street, and the convenience of transition between the 2,” stated Grosjean. “Praga really delivered on my problem! On the street, you get a clean journey, the automobile eliminates the bumps, you may chat with the passenger, and every little thing is calm and OK. Then merely swap focus, and you might be on the observe.”
Inside, in the meantime, Praga stated it was vital for it to design a automobile that’s snug sufficient for big adults. It options adjustable seats, steering wheel, pedals, and extra. It has storage to your smartphone and water bottles, in addition to air con for hotter days. Praga says that the cockpit’s design was impressed by its aviation and racing divisions, which explains the in depth use of Alcantara.
In all, Praga will construct simply 89 Bohemas, to have fun the 89th anniversary of the Praga Alfa’s victory on the 1,000 miles of Czechoslovakia street race in 1933. Costs for the supercar will begin at $1.31 million and manufacturing is predicted to start within the Czech Republic, within the second half of 2023. As soon as manufacturing is up and working, it hopes to construct 20 Bohemas per yr. The corporate is now taking orders and is in discussions for gross sales within the U.S., the U.Okay., Germany, Japan, Hong Kong, Australia, and different supercar markets.
