1981 Lotus Sunbeam<\/h1>\n
\n

The Lotus Sunbeam Competition was built to satisfy homologation requirements so that ten ‘works’ rally cars known as the WRW 30S could by contested by Talbot\/Chrysler in FIA World Rally.<\/span><\/p>\n

Only 32 homologation cars were made and featured a competition engine rated to 234bhp with 48mm Weber carburettors and a high compression ratio. The same engine was tuned to over 400 bhp in competition to keep up with the Ford RS Escorts and Vauxhall HS Chevettes.<\/p>\n

In contrast, the regular production model was rated at a modest 160 bhp, but still featured many of the hallmarks from the works rally and homologation cars. Under the hood was basically the same 2.2. litre twin-cam engine which was left over from the ill-fated Jensen Healey marque. Called the type 911, it had twin 45mm Dellorto carburettors, the famed 16 valve cylinder head, all-alloy block and 155bhp.<\/p>\n

Around 3000 Lotus Sunbeams were produced on both the Chrysler and Talbot base models.<\/p>\n
