Quantum Sports Cars

Quantum's first car was the Mark 1 hatchback (also known as the Mk 1 Coupé) which was based on the Ford Fiesta Mark 1. It reused all of the donor's mechanical and trim components in an elongated, more rounded shape. Due to its reduced weight over the donor vehicle, performance was significantly improved. The Coupé is unusual for low-volume car manufacturer in that it has a glass-reinforced plastic (grp) monocoque rather than a separate metal chassis. This approach relied upon the use of computer analysis to ensure that structural rigidity would not be compromised, offering the strength of a steel chassis but without the weight penalty.

The first Mark 1 Quantum, bearing chassis number 001, was a development mule and was subject to so much adjustment that the Wooldridge brothers eventually decided the car would be too dangerous to keep on the road. This car was therefore disposed of in landfill. Chassis 002 was later believed to have been damaged beyond repair in a head-on collision, so chassis 003 is now the oldest surviving example of a Quantum model and the first to be sold, after a short period being used for magazine tests and promotional materials. To ensure this historic car survives, the Quantum Owners Club has acquired this car and are in the process of restoring it.

The club also owns the last Mark 1 Coupé produced, chassis number 017. In 2015 a club member claimed to own chassis 002, which was believed to have been exported to the Isle of Man, and hence removed from the DVLA records. At the National Kit Car Motor Show in 2017 chassis number was validated by the Committee Members in the Quantum Owners Club who can now confirm this is the oldest surviving Quantum.

In 1991, the Quantum Mark 2 saloon was introduced, now based on the Ford Fiesta Mark 2 with the rear-end shape changed from a hatchback of the earlier car to a booted saloon. This led to far greater sales success a total of 199 saloon models being produced before that model also ceased production.
