1970 Chevron B16

The Chevron Company was founded by Derek Bennett and within a short period of time had become very successful, with much of the accolades gained with the B8 sports racer of 1967. A prototype racer followed to contest the European 2-Liter Championship, but only after the customer cars had been built. Once work was underway near the close of the 1969 season, it soon became apparent that the single-cam, two-valve head, 2-liter BMW four-cylinder engine used in the B8 was nearing the end of its usable life. A suitable replacement was needed.

Weslake and Cosworth were asked to build a replacement head for the BMW engine, but due to other complications, neither company took on the work. Instead, Cosworth developed an engine called the FVC which had the 116E block similar to the FVA but with a larger bore, displacing 1,790cc and offering 235 horsepower.

The chassis for the new prototype racer was inspired by the existing design and continued the use of a tubular space frame, with steel and duraluminum sheet for extra support. The subframes in the front and back could be removed to help speed up repairs. The suspension was comprised of doubles wishbones in the front. In the back were reversed lower wishbones, trailing arms, and top links. The fiberglass body was created by Specialised Mouldings to a design by stylist Jim Clark.

The new B16 prototype racer made its racing debut with the FVA engine at the Nürburgring 500 km race where it was driven by Brian Redman to pole position and victory. This impressive accomplishment, followed by many other victories, made the B16 popular with privateers, with approximately 23 examples produced. It was able to homologate for Group 5 GT competition, despite not officially achieving the 25 minimum number produced.

During the 1970 European 2-Liter Championship season, the B16's main competition was from the new Lola T210 with open coachwork which was 70 kg lighter than the coupe bodies. Redman and John Burton were the B16 Work's drivers for the season, with Redman winning the first round at Paul Richard. The Lola and Chevron battled all season, with the championship being decided with the final event at Spa.

Redman had Bennett build an open version of the B16 with a design mirrored from the Porsche 908/3 which Redman had driven that year at the Targa Florio. The B16 coupe and Spyder had the same mechanical components, with the only difference being the body configuration. An unsuccessful debut at the Nürburgring 500 km was followed by a victory at Spa, earning Chevron enough points to win the Championship.

For the following season, Chevron introduced the production version of the B16 Spyder called the B19.

Chassis number: B16 DBE/SP1
Engine number: 0590

There were 23 Chevron B16 models built in 1969 and 1970, plus a B16 Spyder constructed in 1970. The B16 was based on, and evolution of, the B8. It had a spaceframe chassis and reinforced with steel to form a full monocoque. The front suspension was carried by tubular frames. The suspension was double wishbones at the front and upper link and triangular wishbones at the rear. The basic fiberglass body design was created with the help of stylist Jim Clark.

Mounted mid-ship was a Cosworth FVA Formula 2 engine. This was the same found in the B8. Cosworth's main engineer, Keith Duckworth, enlarged the capacity closer to two liters. It was given a different crank and a longer stroke, increasing the displacement from 1598cc to 1790cc. The result was a boost in horsepower to 245bhp and a new designation, the FVC.

In July of 1969, the Chevron B16 was tested at Aintree where it proved to be extremely quick 'right out of the box.' It was close to the lap record. On September 7th of 1969, after continued development and testing, the B16 made its racing debut at the Nurburgring 500 km race. Brian Redman qualified the car on pole and had a full 5.6 seconds ahead of its nearest competitor. The race would be just as successful for the B16, with Redman leading the entire event. It was quick but had a tremendous amount of understeer. This was due to a lack of down-force at the rear. To resolve future B16 models, two orange box rear spoilers were fitted.

The following season, Redman was still Chevron's factory driver. Lola introduced their new T210 which provided considerable amounts of competition for the B16. Redman would lose to the Lola on several occasions (and win on several occasions). He begged Chevron for an advantage - an open car. Only one was ever created.

A few of the customer B16 cars were sent back to the factory in 1972 and converted into B21 cars. These were basically B19 cars with a different cockpit section.

This car was originally a coupe that was converted into a spyder. It is painted in the same red and brown color as the coupe that raced at Nurburgring 500 km in 1969. It has a Hewland FT200 gearbox, coil-over wishbone suspension, and a four-cylinder engine rated at 278 horsepower. The engine is number 0590.

Coupe
Chassis number: DBE28

This 1970 Chevron B16 number 44 is one of 23 constructed with only 17 remaining in modern times. It is powered by a Ford Cosworth four-cylinder engine that displaces 2.1-liters and produces 315 horsepower. The engine is mated to a five-speed TF200 Hewland gearbox and powers the rear wheels.

The B16 Chevron raced in the 1970-1972 World Endurance Series. The B16 was also at the 1970-1972 24 Hours of LeMans. This car has been raced at Daytona and Sebring and was driven in the Steve McQueen movie 'LeMans.'

Coupe
Chassis number: DBE28

Chevron B16 chassis DBE-28 was purchased new by Jo Siffert Racing for Steve McQueen's Solar Productions to use in the making of the film 'Le Mans.' Digby Martland and Clive Baker raced it in the actual 1970 24 Heures du Mans, but were unfortunately forced to retire after 20 hours at lap 187 due to a broken valve spring.

After movie filming was completed, the car was sold to Jean Sage in January 1971. Later that month, he raced it in the Daytona 24 Hours with co-driver Jean-Pierre Hanrioud, they finished 15th. Two months after that, it went to the Sebring 12 Hour, driving shared by Jean Sage, Tom Fraser, Charles Reynolds, and Clive Baker. It didn't fare quite as well, finishing 119 laps behind the winner.

DBE-28 was sold shortly after that and was presumably campaigned in various European events by various privateers. The car was recalled to active duty in 1985 by the Winfield racing school at Circuit Paul Richard in the south of France, where it helped aspiring racers hone their skills for several years until it finally made its way to the United States in the early 1990s. It has been actively vintage raced ever since.

The car is powered by a Cosworth FVC four-cylinder engine displacing 1790cc and offering 240 horsepower. It has a Hewland FT200 5-speed transaxle and weighs 1268 lbs.


Derek Bennett was the individual responsible with the formation of Chevron Cars Ltd. He was a brilliant engineer, mostly self-taught, and had a talent for modifying, repairing, and sculpting automobiles. Near the close of the 1950's he began working in a shop in North England where he quickly developed a name for himself. When he was not working at the track, he could often be seen at nearby tracks where he raced mostly custom-built racing cars.

Changes in racing regulations had many producers of racers scrambling to create a formidable contender that conformed to the new rules. Bennett had been contemplating purchasing a new racer but with the new changes, he felt he could produce a better machine than other marques were fielding. With no drawings and all the details in Bennett's head, he began construction beginning with a tubular space-frame chassis. Power was from a modified Ford Kent engine that had been taken from an Anglia. When the vehicle was complete, it carried the marque name 'Chevron'; the name had been inspired from a Highway Code symbol. Up to this point, his vehicles he had constructed were dubbed Bennett Specials.

The newly created racer, dubbed the B1, made its inaugural appearance in 1965 at Kirkistown, Ireland. Little testing had been done but the car still managed to set an impressive pace and finished in first pace. For the next few years Bennett created racers and gave them various designations. The B1 was introduced in 1965 and followed a year later by the B2. Both were Clubmans which was a British national formula series for open-top sports cars with Ford engines placed in the front of the cars.

The B3 was Bennett's first attempt at Gran Turismo competition. The 1.6-liter twin-cam Ford engine was mounted behind the driver and in front of the rear axle. The car was constructed for Alan Minshaw who had seen a small-scale model on Bennett's desk and had immediately produced funds to finance its construction. The initial estimates to create the car fell short of the actual figure and Digby Martland stepped in to provide the additional funds needed to complete the project. Once the project was complete, Bennett created a second racer, dubbed the B4, and fitted it with a BMW 2-liter engine.

During some initial trial runs of the Martland B3 racer, it attracted the attention of Peter Gethin who immediately ordered one for himself. The B3 made its racing debut a short time later where it emerged victorious. The Ford powered car was very impressive whereas the BMW powered B4 suffered from lubrication problems. The reason for this was the way the BMW engine was installed which sat vertically which prevented the oil to properly drain. A custom dry-sump lubrication system was later installed and resolved these issues.

After securing a deal with BMW Motorsports to supply engines through a dealership at discounted price, Bennett began creating more examples of the B4 GT car.

The B5 was powered by a BRM 2-liter V8 engine. Brian Redman drove a B5 in international competition in a Group 6 at Brands Hatch where he emerged victorious. This was Chevron's first international race win. Redman would go on to become a works driver for Chevron.

The B6 was very similar to the B4 but with a fiberglass body. It competed in Group 6 prototype competition against tough competition from Ferraris and other big-named marque's. After enough examples were created to homologate the cars, they were then able to compete in Group 4 GT competition. 50 examples had been required in order to compete; not all 50 were created - when the FIA stopped by Bennett's shop to perform the count, Bennett proved he had enough materials to create the racers. Only 44 examples were ever created.

The B7 was a single seat racer which competed in Formula 3 competition. The B8 was the 1968 version of the GT racer. The B9 was a Formula 3 car. The B10 was a Formula 2 racer.

The replacement for these two-liter cars came with the B16 and was quickly replaced with the B16 Spyder which had bodywork inspired by the Porsche 908 Spyder. The Chevron was a continuation of the B8 with styling help from Jim Clark. It had a spaceframe chassis, monocoque design, tubular frames, and a fiberglass body. The engine and gearbox was both placed midship. To make the vehicle easy to maintain, it had a removable front subframe. A 1790cc FVA Cosworth engine was used which provided an impressive 245 horsepower.

The B16 made its inaugural debut at the 1969 Nurburgring 500km race where it was driven by Brian Redman and qualified for pole position. From the start of the race, Redman led the pack and continued this for three-and-a-half hours before crossing the finish line victorious. The car was surprisingly fast though it did suffer from under-steer due to not enough down-force. The problem was later solved by adding two orange box rear spoilers

During the 1970 season, Lola introduced the T210 which had Redman struggling to maintain the lead. It was not long before the T210 was consistently beating Redman and the B16. Redman approached Bennett requesting an open car that was lighter and more nimble. The result was the B16 Spyder of which only one was ever created. This would set the foundation for the rest of the cars for years to come.

The B19 was introduced in 1971 and the B21 in 1972. These were used in Group 6 competition. The B23 was introduced in 1973; the B26 was also a 1973 car; the B31 was the final iteration of Group 6 cars introduced in 1975.

In 1972 the B24 was introduced and intended for F5000 competition. Continuing the tradition of Chevron cars, it won its inaugural race. Driven a year later by works driver, Peter Gethin, it became the first F5000 car to beat the F1 cars. The B24 were impressive racers but the Lola T330 cars were faster. Chevron would finish the season with 32 Top 3 finishes from 35 races while Lola managed 39 Top 3 finishes.

It is believed that eight examples (possibly 10) of the B24 were constructed. One was later rebuilt to B28 specification.

Other interests of the Chevron company during this time were Formula competition such as Formula Atlantic and Formula Two. Examples include the B25, B27, B29, B35 Formula Atlantic/Formula Two cars.

Derek Bennett's passed away after a hang-gliding accident. The company continued for a number of years. Ownership passed through the hands of a few owners.
