Full details about the Praga R1 track racer

Earlier this week, Praga Cars has released full details of its upcoming hand-built R1 track racer. The vehicle weights around 590 kg (1300 lbs) and it features a carbon fiber monocoque reinforced by internal ribs and bulkheads. The 4144mm long, 1800mm wide and 965mm tall vehicle has a wheelbase of 2527mm and it features carbon fiber crumple zones aside all the usual race car safety equipment. ( integrated fire extinguisher system, six-point seatbelts with HANS, 60-liter safety fuel tank and polycarbonate windows )

Under the bonnet, the R1 has been fitted with a longitudinal mounted, naturally-aspirated, 4-cylinder 2.0-liter engine built by Renault Sports Technologies. The power mill generates 210 HP – 155 kW at 7,500 rpm and 220 Nm (162 lb-ft) of torque at 4,500 rpm. This enables the vehicle to have a power-to-weight ratio of 356 HP per ton.

All this power goes to the wheels via a six-speed Hewland JFR sequential transmission with a KMP pneumatic paddle shifting system. On the other hand, the braking power is provided by AP Racing brakes with four-piston calipers, while the suspension consists of a KONI two-way adjustable, mono-tube with adjustable anti-roll bars and custom-made progressive racing coil springs.

The vehicle sits on 15×8 front wheels and 16×10.5 rear wheels wrapped in 200/580 R15 rubbers at the front and 265/605 R16 Dunlop racing tires at the back. For next year’s season the Praga R1 will compete in its own Praga Cup series on various European circuits.
