By 1967 Chevron, under the direction of British engineer Derek Bennett, had already produced a small number of sports racing models and was developing a reputation for competitive, privateer-friendly machinery. The B5 differed from the standard Chevron production model approach in two significant respects: it was constructed not by Chevron itself but by David Bridges, and it used the BRM V8 engine rather than the Ford or BMW units found in contemporary Chevron cars. This made the B5 an unusual and distinctive entry in the company's early history — an external build commission using a high-specification racing engine.
The B5 was powered by a naturally-aspirated 2.0-litre BRM V8 engine. BRM — British Racing Motors — was one of the most storied names in British motorsport, and its V8 engine had seen service in Formula One competition. Using a BRM V8 in a sports prototype gave the B5 a more exotic and high-performance character than the four-cylinder units that powered Chevron's earliest cars, including the B3 and B4. The V8 configuration typically offered a higher rev ceiling and a different power delivery profile compared to the four-cylinder alternatives, potentially giving the B5 an advantage in circuits where top-end speed was at a premium.
The fact that the car was built by David Bridges rather than within Chevron's own Bolton facility distinguishes it from the standard production models. This external construction arrangement may reflect the bespoke nature of the project — a one-off commission built to a customer's specification using Chevron's design input but constructed through a different workshop.
Despite being a unique, one-off chassis, the Chevron B5 compiled a creditable competitive record. Over a racing career spanning four years from its 1967 construction, it won 3 races outright and scored 7 podium finishes. The four-year active career of a car built as a single example is itself noteworthy; the B5 was evidently well-maintained and kept competitive over a period that saw significant development in sports car racing machinery.
The 3 outright wins demonstrate genuine front-running pace rather than mere participation, and the 7 podium finishes indicate that the car was consistently near the lead when it finished. For a unique, privately commissioned sports prototype running against series-built machinery, that record represents a strong competitive return.
The Chevron B5 occupies a particular niche in Chevron's early history as an externally built, one-off model using premium racing engine technology. Its use of the BRM V8 connected the car to a strand of British motorsport heritage that sat outside Chevron's typical powertrain partnerships, and the involvement of David Bridges as builder adds a collaborative dimension to the story of the company's formative years. The car's four-year winning record confirms that even as a single-chassis experiment, it was a genuine racing machine rather than a novelty.
