Our history

Many owners wanted to 'graduate' from Caterhams and Lotus Elises in search of the ideal everyday/trackday package.

They were also clear that they loved the Scorpion III's ultra-modern, minimalist styling. So Steve Harper, now Volvo's Chief Designer, the man who drew the SIII also drew the SIV and there is a clear family relationship between the two.

Findings from the research and development of the highly-acclaimed Scorpion III went into the building of the new Scorpion IV chassis; a space-frame structure which is remarkably rigid, yet respectably light.

The front suspension is a development of that which works so well on the Scorpion III; double wishbones in oval tubing with inboard coil springs over custom built Harvey Bailley dampers. At the rear, long, super-stiff longitudinal links which give superb handling and camber control without compromising the vehicle's distinctive styling.

Exhaustive trials of possible power-trains included Rover K-series, Honda VTEC and Fiat 20v turbo - all fine products. Eventually however, we signed an OEM supply deal with a leading European manufacturer for a lightweight 225bhp turbo unit and six-speed gearbox. After four years of continuous development, the result is truly impressive.
