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.
M13A The M13A displaces ; bore and stroke is . 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.

M16A The M16A displaces . Bore is and stroke . This engine has a DOHC variable valve timing valve train and a multipoint injection system. The engine had many iterations, depending on the car in which it was installed and the intended use of the car. The M16A engine uses a chain cam instead of a cam belt. General dimensions:

Suzuki Swift Sport, 2nd and 3rd generations
M18A The M18A is based on the M16A, with a larger bore. It is the only M-series engine to use a different bore. It displaces ; bore and stroke is . This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces at 5,500 rpm and 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.
