The Suzuki M engine family is a line of automobile engines from Suzuki. Ranging in displacement from 1.3 L to 1.8 L, it is a modern engine line with dual overhead cams, 16 valves, and multi-point fuel injection (MPFI). Fully developed in-house following Suzuki's separation from General Motors, the M engine replaced the long-lived G engine family.[1]
M13A
The M13A displaces 1.3 L (1,328 cc); bore and stroke is 78 mm × 69.5 mm (3.07 in × 2.74 in). It has a 9.5:1 compression ratio and two variants:
- with variable valve timing (VVT) valvetrain
- without VVT (Suzuki Jimny, Suzuki Ignis, Suzuki Liana) in select markets.

M18A
The M18A is based on the M16A, with a larger bore. It is the only M-series engine to use a different bore.[1] It displaces 1.8 L (1,796 cc); bore and stroke is 83 mm × 83 mm (3.27 in × 3.27 in). This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces 125 PS (92 kW) at 5,500 rpm and 170 N⋅m (125 lb⋅ft) at 4,200 rpm.
Due to the engine block being based on the same casting, a M16A cylinder head can be bolted onto a M18a shortblock with minor modifications. This has been done by tuners, by installing a M18A block with the stock internals (crank, pistons and rods) in a Suzuki Swift Sport, in order to have more torque on the whole rev band.
Application:
- Suzuki Aerio (Aust. & N.Z.)
- Suzuki Liana GS 2004 (Australia & N.Z.) 125 PS (92 kW)
- 2009-2012 Suzuki SX4 (China) 131 PS (96 kW)
