Chevron B21 classic cars for sale

History of the Chevron B21

Chevron introduced the B21 in 1972 to carve its mark in Group 5 sports prototype competition. The car was developed in Bolton, England, and specifically targeted the fiercely-contested two-litre class—where manufacturers like Lola and Osella fought for supremacy. Across its 13-year racing lifespan, the B21 gained respect by clinching 23 wins, 45 podiums, and 11 pole positions. These achievements reflected both its competitiveness and reliability, strengthening Chevron's reputation within the world of endurance racing.

Model history

The B21 followed the Chevron B19, refining aerodynamics and chassis rigidity for improved high-speed handling. It paved the way for the further-evolved Chevron B23 and later models, which built on its proven reliability and driving dynamics. Each generation incorporated incremental upgrades in suspension, engine installation and safety, responding to ever-evolving sports car regulations.

B21 highlights and statistics

Each Chevron B21 built is a testament to British low-volume, purpose-driven race car engineering. Developed for maximum efficiency under Group 5 regulations, it became a favourite among privateers for its lightness and composure on the track. The selection of Ford-Cosworth BDG or BMW M12/7 engines underlines the B21’s versatility and appeal to different teams, while its 13-year presence in competitive motorsport is remarkable for a prototype of this era.

Technical data

Special editions and collectible models

No formal factory special editions are documented for the B21, but each example is unique due to individual race histories, engine configuration and period modifications carried out by teams. Cars with championship victories, documented provenance or rare engine swaps attract particular attention from collectors and historic racers.

Common issues and maintenance

Owning a Chevron B21 requires keeping vintage race technology in top shape—regular inspection of alloy suspension components for fatigue, ongoing care for the Cosworth or BMW engines, and attention to aging fuel and electrical systems. Replenishing specialised parts may require sourcing from Chevron specialists or bespoke fabrication.

Engine, Performance, and Handling

Powered by either the Ford-Cosworth BDG or BMW M12/7 in-line four, the B21’s 275 hp motivates just over 600 kg. Strong torque response and a rev-happy character made for excellent acceleration, while the fully independent suspension and disc brakes gave exceptional track agility. The B21 could be optimised for high-downforce circuits or lower-drag endurance setups depending on the racing venue. Notable variants include B21s fitted with period BDG powerplants, as well as BMW-powered chassis which saw use in the European 2L sports car scene. Cars with original documentation and untampered chassis are prioritised by specialist buyers.

Design: Cockpit, Finish, and Racing Details

The B21’s exterior is marked by a low, aerodynamic nose, expansive wheel arches, and a prominent rear wing. Inside, the sparse cockpit is built for functionality—allowing rapid access to controls and clear sight lines for drivers. Many cars retain original Chevron steering wheels, Smiths instrumentation, and signature Chevron detailing. Livery usually reflects the founding team’s colours or later historic racing preferences, with bright hues and sponsor decals showcasing the early 1970s era.

Other features

Each B21 tells its own story in racing, with examples appearing in everything from classic endurance events to recent historic racing series. The car’s ongoing presence at Goodwood Revival and Le Mans Classic underlines its suitability for vintage motorsport and the enthusiasm it garners from spectators and drivers alike.

Summary

With its low build numbers, versatile two-litre power and successful international record, the Chevron B21 remains one of the most respected British sports prototypes of the 1970s. Its rarity and racing pedigree make it a continually fascinating choice for drivers, collectors and motorsport enthusiasts.
