The Marcos of Ian Pearson and Callum Grant and the Shelby Daytona Cobra of George Pochciol and James Hanson, in the International Pit Lane, Silverstone
The Marcos GT is the name used by the British firm of Marcos Engineering Ltd for all of their cars until the introduction of the Mantis in 1970. Most commonly, the name is used to describe the very low coupé designed by brothers Dennis and Peter Adams. The car was first introduced as the Marcos 1800 in 1964, with a wooden chassis and a Volvo P1800 engine. Later models had a steel chassis and commonly Ford engines although others were also available. The majority of these sports cars were sold in kit form. The car was out of production from 1972 until 1981, when small scale kit production recommenced. The original GT continued to be built until 1989 or 1990, being developed into its altered Mantula form. This was further developed into more powerful and aggressively-styled designs, culminating in the 1994 LM600 (which competed in the 1995 Le Mans 24-hour race). As was the intent with most Marcos products, the GT series saw much competition use. The original 1800 and other 1960s and 1970s Marcos are still competitive in both FIA and HSCC (UK) historic racing series. The AC Cobra, sold as the Shelby Cobra in the United States of America, is an Anglo-American sports car with a Ford V8 engine, produced intermittently in both the UK and United States of America since 1962. Production proved to be easy, since AC had already made most of the modifications needed for the small-block V8 when they installed the litre inline 6 Ford Zephyr engine, including the extensive rework of the AC Ace's front end bodywork. The most important modification was the fitting of a stronger rear differential to handle the increased engine power. A Salisbury 4HU unit with inboard disc brakes to reduce unsprung weight was chosen instead of the old unit. It was the same unit used on the Jaguar E-Type. On the production version, the inboard brakes were moved outboard to reduce cost. The only modification of the front end of the first Cobra from that of the AC Ace was the steering box
