Westfield XTR2

This is the third Westfield to use a bike engine. The first, the XTR, featured a 900cc Honda Fireblade unit, but the new version borrows from a 1.3-litre Suzuki Hayabusa. The name stands for 'Extreme Track and Road 2002' and, while it might look more at home on the Mulsanne than in Milton Keynes, it's billed as the ultimate track-day car which can take to the road.

Squeezing down into the cockpit and putting on the four-point racing belts takes a bit of getting used to, but the £225 optional quick-release steering wheel makes entry slightly easier. An offset driving position and an array of unmarked switches and lights also require time to get accustomed to.

A body that borrows styling cues from a Le Mans racer and weighs only 440kg promises rapid performance, and this car is seriously fun to drive. Depending on how a buyer asks West-field to set up the machine, the XTR2 can do 0-60mph in a claimed 3.1 seconds before going on to hit a top speed of 150mph. It also comes with a race track suspension set-up, huge wing and venturi funnels at the rear, which help glue the car to the track.

Whether you would take this out on the road depends on your disposition. The XTR is tractable, picking up from low revs even if the six-speed sequential box is in the wrong gear, but the lack of a windscreen means you need goggles or a helmet. The sharp clutch would be a pain in traffic and the 'go flat out or go home' nature of the throttle is at odds with the speed limit.

But if your appetite has been whetted, you'll be pleased to know there's more to come from Westfield. As the 2002 part of the name suggests, a 2003 version is already on the cards.
