Having competed in the British Touring Cars Championship since 1993, Renault joined forces with Williams, its partner in F1™. Following an initial upgrade, the Laguna was then comprehensively overhauled with extensively developed aerodynamics and a two-litre, four-cylinder engine, with the power output extended to 295 hp by Sodemo. The car enjoyed almost immediate success. It proved to be an absolute racing monster, winning more than half of the races with the experienced Alain Menu and the young Jason Plato, who was in his first full season in the BTCC having previously competed in the Renault Spider Championship. Renault went on to win both the Drivers’ and Manufacturers’ titles, as it had done in F1™. Two years later, the Laguna ended its run in the BTCC with four titles and thirty-eight race wins.
