Quantum Xtreme
PRODUCED BY ONE of the best established names in the kit car industry, the Quantum Xtreme is notable for its hugely strong, stainless steel monocoque chassis. As a result, the car’s all-independent suspension works extremely efficiently, which leads to unusually good ride comfort and superb levels of handling and roadholding. Also outstanding is the amount of space in the cockpit; it’s greater than in many cars of this ilk and means the Xtreme can be driven in comfort for long distances. A one-donor car, the Xtreme is largely Sierra based, although most of the suspension parts are actually made in-house, including the wishbones and all four fabricated uprights. Although originally designed for a Pinto engine, most cars are now built using a Zetec or 1600SE engine. The company is currently working on turnkey engine packages with engine management specialist Omex Technology. As the Xtreme weighs only 620kg, performance is truly impressive whichever engine is fitted. Finished in coloured gelcoat, the main body panels are made to high standards in GRP – the bonnet, scuttle, nosecone, rear section and all wings. Other notable aspects of the Xtreme are its highly individual dashboard styling and unusually sizeable boot with locking lid, which certainly helps in the practicality stakes. No question about it, the Xtreme has an innovative, refreshing approach to user-friendly roadster packaging. Quantum Cars was taken over in 2009 by Mark Burley of MB Motorsport. He has injected fresh energy into the company, and 2011 saw the facelifted Xtreme shown to the press with even higher levels of quality on the bodywork, Omex Power range of engines, interior modifications and a redevelopment to remove hard-to-get donor items.
