The Ford GT40 is a high-performance mid-engined racing car originally designed and built for and by the Ford Motor Company to compete in 1960s European endurance racing. Its specific impetus was to best Scuderia Ferrari, which had won the prestigious 24 Hours of Le Mans race for six years running from 1960 to 1965. Around 100 cars have been made, mostly as 289 cu in (4.7 L) V8-powered Mk Is, some sold to private teams or as road legal Mk III cars. Racing started in 1964, with Ford winning World Championships categories from 1966 to 1968. The first Le Mans win came in 1966 with three 427 cu in (7.0 L) powered Mk.II prototypes crossing the finish line together, the second in 1967 by a similarly powered highly modified US-built Mk.IV "J-car" prototype. In order to lower ever-higher race top speeds, a rule change from 1968 onwards limited prototypes to 3.0 litre Formula 1 engines; a loophole, however, allowed the private JW "Gulf Oil" team win at Le Mans in 1968 and 1969 running a Mk.I with a 5.0 litre engines.
Power-to-weight ratio is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance.
Chaparral Cars was a pioneering American automobile racing team and race car developer that engineered, built, and raced cars from 1963 through 1970. Founded in 1962 by American Formula One racers Hap Sharp and Jim Hall, it was named after the roadrunner, a fast-running ground cuckoo also known as a chaparral bird.

The McLaren M6A was a Group 7 prototype race car designed and developed by driver Bruce McLaren, and built by his Bruce McLaren Motor Racing team for their entry in 1967 Can-Am season. As a replacement for the team's M1Bs from 1966, the Chevrolet-powered M6A's improved design earned Bruce McLaren and his team their first of multiple Can-Am championships. After the M6As were replaced by the M8A in preparation for 1968, McLaren and technical partner Trojan–Tauranac Racing developed the M6B which was sold to customers for use in Can-Am as well as other racing series.
The McLaren M8A was a race car developed by driver Bruce McLaren and his Bruce McLaren Motor Racing team for their entry in 1968 Can-Am season. The M8A and its successors dominated Can-Am racing for four consecutive Can-Am seasons, until the arrival of the Porsche 917.
The Lola T160, and its evolution, the Lola T165, is a series of purpose-built Group 7 sports prototype race cars, designed and developed by British chassis manufacturer Lola Cars, specifically to compete in the Can-Am series in 1968. It was the successor to the competitive T70, sharing similar design knowledge and cues. Lola built the chassis, constructed out of fiberglass, and molded into an aluminum monocoque. This meant the car was light was lightweight, weighing only 670 kg (1,480 lb). The chassis was designed to accept a small-block engine, but most cars were powered by either the Chevrolet ZL1 or the Ford FE "big-block" motors, generating about 625–750 hp (466–559 kW); mated to a 4-speed or 5-speed Hewland L.G.500 or L.G.600 manual transmission. This made the cars very fast, with a notably excellent power-to-weight ratio. It was used in active competition until 1971, and was succeeded and used alongside the new T220 in 1970.
