Westfield XTR2

The Westfield XTR2 is an ultralightweight, two-seater sports car manufactured by Westfield Sportscars Limited, UK. It features a lightweight steel tubular spaceframe chassis, and the 170 horsepower, 1299cc Suzuki Hayabusa 4 cylinder engine. Performance upgrades are available, however. It lacks a windshield, side doors, roof, and is virtually devoid of interior luxury.

As a result of this simplicity, the car only weighs between 410-440 kilograms, depending on configuration. By achieving an extremely high power to weight ratio, it has been intended primarily as a car to be used on the race track. However, it is still legal for road use ( at least in the UK).
