Chevron B31 classic cars for sale

History of the Chevron B31

Chevron Cars Ltd introduced the B31 in 1975 as a response to the rapidly evolving world of sports car racing. Building on the foundation of the B26, the B31 quickly established a reputation on the European 2-Litre Championship circuit for its engineering versatility and resilience under race conditions. Chevron’s expertise in building lightweight, precise-handling racing machines continued with the B31, which was campaigned by numerous private teams across Europe soon after its debut. Its modular design philosophy made it a go-to chassis for teams looking to experiment with engine configurations and strategies throughout its active racing years.

Model History

The B31 evolved directly from the Chevron B26, inheriting the lessons learned from prior models in terms of aerodynamics and chassis stiffness. While the B26 paved the way for Chevron’s recognition among privateers, the B31 allowed even greater flexibility in engine choices. Over its run, the model saw installations ranging from the respected Hart 420R 2.0-litre four-cylinder to the Cosworth DFV V8, as well as the Cosworth FVD and BDG powerplants, and the BMW M12. Its direct successor was the Chevron B36, which continued the marque’s tradition into the late 1970s with further aerodynamic and mechanical refinements.

Highlights of the Chevron B31

The B31 distinguished itself with its modular construction and its adaptability to a range of powerful racing engines. Originally intended for the competitive 2-litre category, it remained relevant thanks to its ability to accommodate larger 3-litre powerplants and to be tailored for different racing needs. Its combination of lightweight construction and aerodynamic refinement made it formidable on European circuits. From a market perspective, every Chevron B31 for sale represents the entirety of the marque’s activity in this model line, as current supply statistics indicate that 100% of listings available from Chevron are B31s. Likewise, buyer interest is solely concentrated on this model, demonstrating its unique significance within the Chevron range.

Technical Data

Special Editions and Collectible Models

Some Chevron B31s are fitted with rare engine combinations—such as the 3-litre Cosworth DFV V8—making them particularly prized among historic racing enthusiasts. Additionally, chassis with significant race histories or notable competition achievements at major endurance events are considered especially desirable by collectors and racing historians.

Engine and Performance, Transmission and Handling

The B31’s mid-engined layout, combined with lightweight bodywork and a race-bred suspension, provided exceptional balance and agility through high-speed corners. The Hart 420R-powered variants delivered up to 290 hp, but those equipped with the Cosworth DFV V8 offered even greater straight-line performance at the expense of added complexity and maintenance. Stopping power and mechanical grip were bolstered by advanced brakes and bespoke suspension setups tailored for various racing conditions. Chevron’s racing know-how is evident in every aspect of the car, from its responsive steering to its ability to accept upgrades and modifications depending on the circuit or series. - B31 Hart 420R: 2-litre, 4-cyl., 290 hp, popular in the European 2-Litre series.

• B31 Cosworth DFV: 3-litre, V8, significant power boost for endurance racing.
• B31 BMW M12: 2-litre, 4-cyl., chosen for its reliability and tuning potential in endurance events.

Interior, Comfort, Exterior and Design

The Chevron B31’s cockpit features only the essentials for racing—lightweight bucket seat, basic instrumentation, and controls optimised for the driver’s ergonomics and rapid adjustments during a race. The exterior design emphasises a low, wide stance with flowing fibreglass panels sculpted for aerodynamic performance. Special attention was paid to airflow management and cooling for the high-output engines, resulting in characteristic air intakes and venting. Lightweight magnesium or alloy wheels, quick-release steering, and removable panels were typical. No special equipment or comfort features beyond racing requirements were provided, underlining Chevron's singular engineering focus.

Summary

The Chevron B31 encapsulates the peak of mid-1970s British sports prototype engineering, designed for adaptability and high performance in the competitive European racing scene. Its unique position as the sole listed Chevron model enhances its desirability for dedicated motorsport collectors, particularly with high-profile race history or special engine configurations. Famed for its robust engineering and modular approach, the B31 remains a marquee entry into historic racing and specialist collections alike.
