The original 1973 Robin was powered by a 750cc engine that yielded 32 bhp and came in three body styles, Saloon, Estate and Van. The Saloon and Estate were available as standard models or as “Super” models, such as the one seen here, that included extras like (would you believe) additional dash clocks and uprated radio. In 1975 the engine was uprated to a larger 40 bhp 850cc engine giving a top speed of 85 mph and a 0 - 60 mph time of 16.1 seconds.
