builder's own 850 cc Mini. Construction took place over approximately 15 years, during which time the racing class the car was intended to compete in was ended. Technical The Unipower GT made extensive use of mechanical components from the BMC Mini. The engine was the BMC A-Series engine, with a cast iron block and head. As in the Mini, this four-cylinder overhead valve engine was mounted transversely and had its gearbox unit in the engine's sump, sharing lubricating oil with the engine. In the Unipower GT the powertrain was mounted behind the driver and passenger and just ahead of the rear axle in a rear mid-engine, rear-wheel-drive layout. Two versions of the engine were available; a engine from the Mini-Cooper and a more potent Cooper "S" engine. Both versions received their air/fuel mixture through a pair of SU HS2 carburettors. The relocation of the engine to the middle of the car resulted in the shift gate being located on the right-hand sill in the right-hand drive cars. The spaceframe chassis was fabricated of square and rectangular cross-section steel tubing and included integrated roll-over protection. The main portions of the fibreglass body were bonded directly to the chassis, increasing stiffness. Suspension was independent all around, with wishbones and coil-over dampers in front and lateral links and trailing arms with coil-over dampers in the rear. Other components were sourced from the parts bins of a variety of major manufacturers. The front uprights were from the Mini, with the spindles cut off. The steering rack was also a Mini part, but from the left-hand drive model. The front indicator lamps were from BMC's Austin 1100 model. The windscreen and instrument panel cover were from Triumph's Spitfire product line. The door hinges and locks came from the Ford Cortina. The headlamp assemblies came from the Jensen C-V8. Taillamps were sourced from the Vauxhall Viva HA. The interior of the car was trimmed out by coachbuilders Wood & Pickett. Technical summary Motorsports In addition to the road cars, the factory produced seven GTs built specifically for competition. The interiors of these cars were stripped of all unnecessary trim and carpeting. Brakes at all four wheels became Cooper 'S' discs, and anti-roll bars were fitted front and rear. Other upgraded components included Rose-jointed suspension links, adjustable dampers, an adjustable brake balance bar, and a rubber bladder fuel tank bag and Monza-type fuel filler cap.
