The F5A was basically a three-cylinder version of the F8A four-cylinder engine, without the fourth cylinder and the stroke reduced from 66 to 60 mm.

Available in various versions with 6, 9, or 12 valves and SOHC or DOHC head designs, carburettor or fuel injection and naturally aspirated, turbocharged, or supercharged.

This engine has never been offered in Japan and was originally intended for export models of the Suzuki Alto.

[8] Applications: The SOHC 12-valve version of F8B engine, developed by Maruti Suzuki in India, introduced in 2000.

Debuted in 1978 Suzuki SC100, but most of the applications were ceased at least until late 1990s for international market with stricter emission regulation, such as in Europe.

In 2005, this engine was upgraded with fuel injection and catalytic converter to meet Euro 2 emission standard for Indonesian market Suzuki Carry 1.0.

[11] In 2017, this engine was upgraded again to meet the Euro 4 emission standard for Vietnamese market Suzuki Super Carry.

The bore and stroke of F10D is the same as that of the smaller sibling and shares quite a few parts like pistons, rings, connecting rods, and valves.

The head is much longer than the F10A version, with a three-inch overhang over the gearbox, due to a sensor on the end of the camshaft in place of a traditional distributor, and with a cast aluminium coolant outlet bolted onto the block, consisting of a thermostat, protruding even further.

The oil pick up pipe and it's mounting points are completely dissimilar on the RWD F10A, and both have different cranks and bearing caps While the F10A and F10D could bolt to each other's FWD/RWD gearboxes and engine mounts, the F10D occupies more space and would need an updated oil feed system.
