The Praga R1 is a racing and sports car made by Czech car manufacturer Praga. The cars raced on the Supercar Challenge and the Britcar Endurance Championship.

Development

The first Praga R1 was built in 2012. Official Praga testdriver Danny van Dongen drove the car for the first time on October 10, 2012.[2] Production of the R1 began in March 2013.[3]

Racing history

On 15 November 2012 the Supercar Challenge organisation in conjunction with Praga Racing and Radical Benelux launched a new racing class.[4] The Supercar Challenge Superlights would feature four sub-classes, one for the Praga R1, one for the Radical SR8, one for the Radical SR3 and one for Group CN cars.

2013

The first race of the Superlights class was run at the Slovakia Ring. Praga Racing announced that they would enter 10 Praga R1's in the first round. Due to a strike in the Spanish customs division most of the wheels, produced by Spanish company Braid Wheels, did not arrive in time. Due to not having enough wheels only three cars could start the first race.[5] The drivers (Van Dongen, Wagner, Hrobarek and Rosina) had their first racing experience with the Praga R1 on May 17. Danny van Dongen was the fastest Praga in free practice, setting a third time overall behind two Radical SR8's, and in front of a Norma M20F and two Radical SR3's.[6] Danny van Dongen took the first pole position in the PR1 class, fourth overall.[7] Stefan Rosina won the first race.

At the Menzo 24 Hours of Zolder the Praga R1 was classified 3rd in class and completed the first ever 24 hours race with the Praga R1. The drivers were Ronald van Loon, Nol Köhler, Berry van Elk and Carlo Kuijer.

The Praga R1T was entered for the 2019 Britcar Endurance Championship, being run by VR Motorsport, with drivers Tim Gray, Grant Williams and Alastair Boulton at the wheel in various parts of the season. It had been a strong contender in the championship but in the second half of the season, the car experienced problems and dropped to sixth before having a good race in the final round of the championship at Brands Hatch. After swapping the provisional pole position spot with the Brabham BT62, it ended up third on the grid. In the first race, fuse problems, accompanied by a door issue put the car down the field in 11th at the end of the race. In the second race, the car was a lot more reliable, ending the race in 2nd place. The team ended the season 4th overall but 1st in class.

2021

Praga unveiled their new all-carbon Praga R1 on 20 January 2021. It was designed to produce 15% more downforce and reduce the drag by 5%.
