Lotus Sunbeam Lotus 2.2 16V
The Talbot Sunbeam Lotus was one of the most improbable and successful homologation specials in rally history. Conceived to give Chrysler (later Talbot) a competitive rally car, it combined the humble Sunbeam hatchback with the potent Lotus 907 2.2-litre twin-cam engine, creating a car that won the 1981 World Rally Championship Manufacturers' title.
The project was born of necessity. Chrysler UK needed a competitive rally car, and the rear-wheel-drive Sunbeam was the only suitable platform in the range. Lotus was contracted to develop the engine installation, fitting its 2.2-litre sixteen-valve twin-cam engine longitudinally in the Sunbeam's engine bay. The result was a car that transformed from basic transportation to genuine performance car.
The Lotus 907 engine produced 150 horsepower in road specification with twin Dellorto carburetors, a significant output from a naturally aspirated 2.2-litre engine in 1979. Rally versions produced considerably more. The ZF five-speed gearbox replaced the standard four-speed unit, and the rear axle ratio was revised for performance.
The chassis received subtle but effective modifications. The suspension was uprated with stiffer springs and dampers, and wider wheels with lower-profile tires improved grip. The front brakes were upgraded to ventilated discs. The overall weight remained modest at 960 kg, giving the car an excellent power-to-weight ratio.
Exteriorly, the Sunbeam Lotus was distinguished by a black exterior treatment including bumpers, lower body panels, and a discreet boot-mounted spoiler. Silver and black were the most common color combinations. Lotus badges on the front wings and tailgate identified the car, along with distinctive alloy wheels.
On the rally stages, the Sunbeam Lotus was devastating. Driven by Henri Toivonen, Guy Frequelin, and Stig Blomqvist among others, the car won the 1981 World Rally Championship Manufacturers' title for Talbot. The car was particularly effective on loose surfaces where its light weight and responsive engine could be exploited.
Approximately 2,308 Sunbeam Lotus road cars were produced to meet homologation requirements. The car was also assembled partially at the Lotus Hethel factory, where the engine installation was completed. Today, the Sunbeam Lotus is increasingly valued as both a significant rally homologation car and a genuinely enjoyable road car, with its combination of light weight, rear-drive handling, and Lotus engine providing a driving experience that transcends its humble origins.
Rust is the primary enemy; the Sunbeam body was not well protected from corrosion. Check inner wings, sills, rear arches, and floor pans carefully. The Lotus 907 engine is robust but expensive to rebuild; verify condition through compression test. The ZF gearbox is reliable but synchromesh wear is possible. Check for accident damage or rally conversion repairs. Matching numbers and original specification are important for value. Many road cars have been modified with rally-specification components.
Bodies were manufactured at Chrysler's Linwood factory in Scotland, then transported to Lotus in Hethel for engine installation and finishing. Total production was 2,308 units. The car was originally badged as Chrysler Sunbeam Lotus before becoming Talbot Sunbeam Lotus when Peugeot acquired Chrysler Europe. Rally versions used significantly modified engines producing over 250 horsepower.
