The Chevron B36 was a Group 6 (later modified into Group C) prototype sports car, designed, developed, and built by British manufacturer Chevron Cars Ltd in 1976 and used in sports car racing until 1987. Over that time period, it won a total of 14 races, and achieved 43 podium finishes. [1] [2]
In Chevron's nomenclature, the B36 succeeded the B35. However, this was not a sports car, but a Formula 2 vehicle that was also available as a slightly modified Formula Atlantic model. At Chevron, the vehicles were simply numbered, no matter what racing formula they were built for. [3]
Conceived for the 2-liter class of sports car racing, the B36 was a conventional racing car with no major innovations. Since it was intended exclusively for sale, it also had to be easy to maintain. The possibility of using different motor types had to be given. The first chassis delivered were powered by a 2-liter 4-cylinder ROC Chrysler Simca unit. Subsequently, the 4-cylinder BDA engine from Cosworth, a rotary engine from Mazda, the M12 4-cylinder engine from BMW, a 2-liter engine from Ford, and a 4-cylinder powerplant from Hart Racing engines were installed in B36. Larger displacement engines were also used. In 1987, Frenchman José Thibault equipped his B36 with a 3-liter, 6-cylinder PRV engine from Talbot for the 24 Hours of Le Mans. Thibault's car was a special specimen in general. It was the only B36 with a closed body; all other B36s were open Spyders. A special feature of this B36 was the covered front and rear wheels. [4]
Between 1976 and 1978, 21 different individual chassis' were completed and delivered by Chevron. [5]
The racing history of the B36 chassis is extensive and varied. Originally designed for the 2-liter class of international sports car races, some vehicles also came to Japan and North America. Overseas, some chassis have been modified to conform to Canadian-American Challenge Cup regulations, and in Europe to Interseries regulations. [6]
Between 1976 and 1987, B36s were entered in 164 races; all in all, this racing car model has 297 entries. In addition to eleven overall victories, 8 class victories were also achieved; more than 60% of the registered B36 also saw the checkered flag.
The car made its racing debut at the 1976 Monza 4 Hours, a race of the World Sportscar Championship that year. Two B36s were entered in this race; the number 38 car by Italian Giuseppe Piazzi - driven by Piazzi himself and his compatriot Sandro Cinotti, and the number 39 car by the French racing organization Course. There sat François Sérvanin and Laurent Ferrier at the wheel. Both vehicles did not finish. The first finish came two weeks later at the Targa Florio where Giovanni Iacono and Vito Veninata finished the race 36th overall. At the Targa Florio 1977, there was the first race victory. Like last year's race, this was also part of the Italian Group 6 Championship. [7] [8] The car was driven by Raffaele Restivo and Alfonso Merendino. [9]
The two Japanese Hiroshi Fushida and Yōjirō Terada, who drove it regularly in the Fuji Long Distance Series, recorded the most starts with B36s. The last race win for the B36 was achieved in July 1984 by the two Brits Ray Bellm and Mike Wilds in a race for the Thunderports series in Thruxton. [10] The last race was that of José Thibault in 1987 at Le Mans, which ended prematurely after 18 laps driven by an accident. [11]
The Porsche 550 is a racing sports car produced by Porsche from 1953 until 1956. In that time only 90 Porsche 550s were produced, and they quickly established dominance in the 1.1- and 1.5- liter classes. The Porsche 550 is a mid-engine car with an air-cooled four-cylinder engine, following the precedent of the 1948 Porsche 356/1 prototype designed by Ferry Porsche. The mid-engine racing design was further developed with Porsche's 718 model; its advantages led to it becoming the dominant design for top-level racing cars by the mid-1960s.
The Porsche 718 is a series of one- or two-seat sports-racing cars built by Porsche from 1957 to 1962. An open-wheel single-seat model was developed for Formula racing.

Dino was a marque best known for mid-engined, rear-drive sports cars produced by Ferrari from 1957 to 1976. The marque came into existence in late 1956 with a front-engined Formula Two racer powered by a brand new Dino V6 engine. The name Dino was used for some models with engines smaller than 12 cylinders, it was an attempt by the company to offer a relatively low-cost sports car. The Ferrari name remained reserved for its premium V12 and flat-12 models until 1976, when "Dino" was retired in favour of full Ferrari branding.
The Porsche 917 is a sports prototype race car developed by German manufacturer Porsche to exploit the regulations regarding the construction of 5-litre sports cars. Powered by a Type 912 flat-12 engine which was progressively enlarged from 4.5 to 5.0 litres, the 917 was introduced in 1969 and initially proved unwieldy on the race track but continuous development improved the handling and it went on to dominate sports-car racing in 1970 and 1971.

The Ferrari Monza is one of a series of cars built by Ferrari. In the early 1950s, Ferrari shifted from using the compact Gioacchino Colombo-designed V12 engine in its smallest class of sports racers to a line of four-cylinder engines designed by Aurelio Lampredi.

The car debuted in active racing competition at the Easter race in Thruxton in 1955, being driven by Ivor Bueb, and was later entered into the 1955 24 Hours of Le Mans, being driven by John Brown and Edgar Wadsworth, but was unfortunately not classified, because even though the car managed to complete 207 laps around the 8.4-mile Le Mans circuit, it didn't manage to finish within 70% of the winners' race distance. However, between 1956 and 1962, it did manage to rack up and tally an incredible streak of domination and competitiveness, scoring 91 total wins and clinching 236 podiums finishes; an incredible record. It was powered by the 1,098 cc (67.0 cu in) Coventry-Climax four-cylinder engine.
