When first introduced, Japanese-market Sunnys received 1.3 or 1.5-litre E-series petrol inline-four engines, or the 1.7-litre CD17 diesel unit. In mid-September 1987, the E15 was replaced by the new GA generation, cleaner and with more power. This was also the first Sunny to become available with optional anti-lock brakes. A twin-cam 1.6 was also added, at first only to the sporting 306 hatchback but later also in the four-door sedans. Abroad, a few other engine variations were also available, up to a 1.8-litre twin cam in Europe.
