Chevron B23

History

Chevron's 2-litre line matured into the B23 (1973): the B19-lineage architecture's refinement for the class's professionalising seasons — the BDG era's arrival (Cosworth's 2-litre succeeding the FVA's reign as the class's engine turn), the aero development the championship's escalation demanded, and the customer fleet's European-and-national campaigns — with the B26's 1973-74 evolution (the companion designation's development step) carrying the line toward the B31-B36 generations, the 2-litre championship's mid-decade wars (the Lola-and-Abarth arguments continuing, the March-entry seasons) the type's competitive context.

The class's professional turn reshaped the racing: works-adjacent budgets arriving at the two-litre war's front, the aero development's escalation (the wing-and-tunnel arguments reaching the class), and the privateer squeeze the escalation wrote — the B23's seasons carrying the golden formula into its expensive maturity.

The line-maturity positioning structures the type: the golden-war romance's continuation at professional-era stakes, the BDG-transition scholarship (FVA-to-BDG fitment histories per chassis), and the Bolton construction's continuing craftsmanship identity.

The customer map of the seasons completes the picture: British national sports-car rounds and the continental championship's calendar, the hillclimb entries the 2-litre spyders always fed, and the transatlantic sales the marque's reputation carried — the fleet's spread the registers trace entry list by entry list.

The present is the revival class's depth: B23s gridding the 2-litre historic wars beside the B19s, BDG-era economics governing, and the register scholarship's per-chassis apparatus throughout.
