Praga Cars has revealed full details of its upcoming hand-built R1 track racer.
The vehicle is 4144mm long, 1800mm wide and 965mm tall, with a wheelbase of 2527mm. It has a dry weight of 592 kg (1305 lbs) and features a carbon fiber monocoque reinforced by internal ribs and bulkheads. The Praga R1 features carbon fiber crumple zones and has the usual race car safety equipment such as an integrated fire extinguisher system, six-point seatbelts with HANS, 60-liter safety fuel tank, along with polycarbonate windows.
The longitudinal naturally-aspirated, 4-cylinder 2.0-liter engine sourced from Renault Sports Technologies produces 210 HP (155 kW) at 7,500 rpm and enables the vehicle to have a power-to-weight ratio of 356 HP per ton. The 220 Nm (162 lb-ft) peak torque is reached at 4,500 rpm. Power is transmitted via a six-speed Hewland JFR sequential transmission with a KMP pneumatic paddle shifting system.
Stopping 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. It rides on 15x8 front wheels with 200/580 R15 and 16x10.5 rear wheels with 265/605 R16 Dunlop racing tires.
For next year's season the Praga R1 will compete in its own Praga Cup series on various European circuits.
