• Source: Mitsubishi 4A3 engine

The Mitsubishi 4A3 engine is a range of alloy-headed inline four-cylinder engines from Mitsubishi Motors, introduced in 1993 in the sixth generation of their Mitsubishi Minica kei car. It shares a 72 mm (2.8 in) bore pitch with the 3G8-series three-cylinder engines, but has a considerably shorter stroke so as to stay beneath the 660 cc limit imposed by the Kei class.
A 1.1 L (1,094 cc) version was made available in 1997 for larger cars, and was subsequently fitted to the Mitsubishi Pistachio, (and Pajero JR), a limited production car based on the kei class Minica equipped with the company's Automatic Stop-Go (ASG) system for cutting the engine when idling. So equipped, the Pistachio was able to record fuel economy figures of 30 km/L (85 mpg‑imp; 71 mpg‑US).
