At the start of sales in 1978, the Renault 18 was offered with engines that produced a modest 64 or 79 hp. With the advent of the turbo wave, however, the French gave the R18 a 1.6-liter 1980 turbocharged petrol engine, which resulted in a remarkable output of 109 and later 125 hp. Although this did not turn the saloon into a sports car, it did make it a fast touring car with impressive torque at low revs. This report is dedicated to the Renault 18 Turbo with 110 hp and shows it and its relatives in current and historical photos.
