Radiografía: M-Sport Ford Puma Hybrid Rally 1

Chassis

tubular structure

The new Rally 1 rules allow only a few parts of the original bodywork to be used (bonnet, windshield, roof, tailgate); Thus, a hull from the Ford Puma crossover was not used, but the body was molded on a multi-tubular steel chassis, which is more rigid and safe. Wheelbase, 2.6 meters; minimum weight: 1260 kilograms.

Aerodynamics

Wind tunnel

The project of the English M-Sport team of Malcolm Wilson began at the end of 2019 in collaboration with Ford Performance in the United States, whose moving floor wind tunnel served to test aerodynamic solutions with simulations of the car jumping, lurching, sliding and in other typical situations in a rally.

The aerodynamics of the M-Sport Ford Puma Rally 1 were developed in the Ford Performance wind tunnel.M-Sport Press

Mechanics

hybrid drive

To the 1.6 turbo engines that the WRC cars already had, in the case of this Ford the 4-cylinder in-line that the Fiesta WRC used last year (approx. 380 HP and 420 Nm), this Puma adds an electric 100 kW (134 HP) for a total combined power of 500 HP and a torque of 500 Nm.

Battery

extra power

It has a capacity of 3.9 kWh and provides a boost for 3 seconds with a maximum acceleration energy of 250 kJ (kiloJoul). It is charged by regeneration of braking kinetic energy or by an external source in 25 minutes, Maximum charging power: 30 kW.

Transmission

all mechanical

5-speed sequential manual gearbox; bi-disc clutch; front and rear mechanical limited-slip differentials; mechanical center differential; 4×4 traction.

Suspensions

Practical and effective

Independent McPherson type schemes (coil spring and integrated damper) on both axes; the fastest solution to change in a few minutes

Brakes

depending on the surface

For dirt roads 300 mm diameter ventilated discs on all four wheels; for asphalt, 370 mm; 4 piston calipers.
