‘Five steps to revolutionise the benchmark’

4 Light, fast, strong


Our core philosophy when designing the Rp1 was to reduce the weight of the car as much as possible.

By reducing weight, the engine power required to achieve high performance is also reduced, so the engine and gearbox can be made smaller, making the car even lighter. A lighter car means lower forces exerted on the car so other components such as the suspension can become lighter too.

And so the process continues. We followed this philosophy to the point where if an off-the shelf part was not light enough, we designed a bespoke one that would be.

Rp1 weight

The result of this attention to detail is a tub that weighs only 65kg and a whole car that weighs from just 595kg.



Having made all the components lighter you can reap the rewards in terms of faster acceleration, harder braking and tighter cornering.

The light weight of the car, compared to the power and torque of the engine are key indicators of performance. The Rp1’s 540bhp per tonne and 800Nm per tonne are absolutely class leading.



Low weight is of little use if it simply sacrifices strength. Conventional lightweight designs can be prone to chassis flexing and offer little or no driver protection.

We optimised every part and employed cutting edge design, manufacturing and materials technology, to create exceptional structural rigidity.

This in turns gives the Rp1 better chassis dynamics, whilst the structural Tub has been designed to meet FIA side impact standards.
