Praga Cars, Czech Republic's race car specialist, has just unwrapped the new R1 racer in anticipation to the 2021 season. It features a larger fuel tank and essential tweaks to the body and suspension which Praga says will make it an even fiercer corner-carver on the track, where the R1 belongs and thrives.

Firstly, the all-carbon-fiber body hides a 2-liter, four-cylinder turbocharged powerplant. This is what also powered the previous version of the R1 and it's an engine developed with a helping hand from Renault-Alpine.

The mid-mounted unit cranks out 365 horsepower at 6,900 rpm and 395 Newton-meters of torque (302 pound-feet) between 3,750 and 6,000 rpm. It can also function under ideal parameters for 4,500 kilometers (2,796 miles) before having to go through a rebuild process.

Don't let the relatively low output fool you. The improved R1, thanks to the carbon-fiber clothing mentioned above, tips the scales at just 643 kilos (or 1,418 pounds). Or, as Evo points out, it offers the same power-to-weight ratio as a McLaren 765LT - 567 horsepower per ton.

Praga R1 specifications

Unfortunately, Praga didn't offer any performance-related numbers. We do know, however, that the engine mates to a custom-made Hewland JFR six-speed gearbox fitted with a triple-plate race-grad clutch with gears that can be adapted based on the circuit configuration.

In other words, the gearing can be tricked out to favor quick sprints or a higher top speed, depending on the team's strategy. So a 0-60 mph sprint in under three seconds is perfectly plausible from where we're standing.

Elsewhere, the fuel tank's capacity was doubled to 92 liters (24.3 gallons) - enough for around 90 minutes of racing - and the body kit received new aero goodies, including a new splitter, floor diffuser, and rear wing. Oh, and the suspension was also tweaked for more grip and stability.

There's no word on price, though. On the bright side, Praga Cars has already started assembling the R1 at its facility in Slovakia.
