1998 Westfield FW400

Westfield FW400

The Westfield FW400 (Feather Weight, 400kg) took the ‘performance through light weight’ ethos to the very extreme. A carbon fibre monocoque, GRP bodywork and aluminium suspension and braking components kept weight down to a scarcely believable 880lbs.

With a tuned Rover 1.8L VVC engine pushing out 190bhp, the FW400 had a phenomenal power to weight ratio of almost 500bhp/ton.

Acceleration was unsurprisingly dramatic, with 60mph coming up in 3.8sec and 100mph in a mere 8.7sec. Of course light weight also means powerful braking as there is less mass for the discs to slow down.

This made the FW400 an exceptional track day car, if a little frantic for the road!
