Following the Le Mans results, Alpine decided to overhaul completely its prototype design and introduced the Alpine A210 (although some lightly modified M65s also participated in some races badged as A210). In the 1966 24 Hours of Le Mans, Alpine made a 1-2-3 in the energy efficiency index, with speeds of up to 270 km/h using a 1.3-litre engine. An A210 driven by Mauro Bianchi won the overall classification of the 1966 Macau Grand Prix for touring cars. Rédéle used the results to convince Renault of giving him support for the construction of a car aimed at the overall victory in Le Mans. Gordini was commissioned to build a new 3-litre V8 to be fitted on the A210 chassis, although it would not be ready for the 1967 edition. Before the race, the A210 was used for the early test of the first radial treadless tire for racing (the Michelin A1). At the 1967 24 Hours of Le Mans, the official Alpine team and the satellite Écurie Salvin-Calverson entered with seven A210 (five with the 1.3-litre inline-four engine, one with a 1.5-litre engine and one with a 1-litre engine) and a M64 (with a 1-litre engine). A 1.3-litre and the 1.5-litre A210s won their class, although none get an index win.
