Circuit Map Blue — 3 museum-grade prints in this palette. The Renault Alpine A442 competed at Le Mans in the late 1970s as a turbocharged Group 6 prototype, developed with extensive testing at Circuit Paul Ricard. Alpine's Dieppe workshop produced the fibreglass bodies atop aluminium monocoque chassis for Renault's motorsport programme. The Alpine A310 was introduced in 1971 as a successor to the A110, using a steel backbone chassis and fibreglass body with four-cylinder and later PRV V6 engines. Alpine operated from Dieppe under Renault ownership, maintaining rally and road-car identity through the 1970s wedge era. Frazer Nash occupies a singular niche in British motorsport — a specialist builder that prioritized driver engagement and lightweight craft over factory scale, producing cars in numbers small enough that every Le Mans entry feels like a documented event. The Le Mans model name itself declares circuit intent, and the marque's Bristol-engine partnerships delivered reliable power in a package that punched above its displacement on twisty Sarthe sections even when Mulsanne straight speed favoured larger prototypes.
