## 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.

## Palmarès

European 2-litre campaigns through the professional turn's seasons, national sports-car honours — the maturity step's ledger in the class's mid-decade wars.

## What to check before you buy

Line-maturity law: register scholarship per chassis (the run's identities and campaign histories through the marque apparatus), BDG-transition precision (FVA-to-BDG fitment histories pricing specifications — the engine turn's per-car documentation), B23-versus-B26 evolution identity per the companion designations, and the construction-originality forensics Bolton-era stakes set. BDG-first economics as the era's engine law (builder, hours, internals); 2-litre revival eligibility structures the racing life at the class's front-line demand.

## Did you know

- The BDG turn was the class's engine succession: Cosworth's 2-litre ending the FVA reign mid-line — the fitment histories the scholarship tracks.
- The companion designations confuse by design: B23-and-B26 evolution steps the registers separate where listings blur.
- The professional turn raised the stakes: the golden wars' romance continuing at budgets the founding seasons never carried.
