The Mitsubishi 3B2 engine is a family of all-alloy
The 3B20 was designed with the "
Bore pitch
is 80 mm.
The preliminary version of the 0.7 L (659 cc) engine was first seen in the
fuel consumption of no more than 3 L/100 km (94 mpg‑imp; 78 mpg‑US).[3]
The larger 1.0 L (999 cc) capacity of the development engine was outside the limits of the kei class in Japan and was introduced in the second generation of the
smart fortwo.[4]
