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.<ref name=MFan>{{cite web | url = https://car.motor-fan.jp/tech/10018958 | archive-url = https://web.archive.org/web/20210923172459/https://car.motor-fan.jp/tech/10018958 | archive-date = 2021-09-23 | title = 内燃機関超基礎講座 {{!}} スイフトスポーツのテンロクエンジン：スズキ［M series］ | trans-title = Internal combustion engine super basic course: Swift Sport 1.6 engine: Suzuki [M series] | work = Motor-Fan | date = 2021-04-18 | language = ja }}</ref>
==M13A== The M13A displaces {{convert|1328|cc|L|1|order=flip|abbr=on}}; bore and stroke is {{convert|78x69.5|mm|in|2|abbr=on}}. 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 {{Convert|1586|cc|L|1|order=flip|abbr=on}}. Bore is and stroke {{convert|78x83|mm|in|2|abbr=on}}. 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:'''

==M18A== The M18A is based on the M16A, with a larger bore. It is the only M-series engine to use a different bore.<ref name=MFan/> It displaces {{convert|1796|cc|L|1|order=flip|abbr=on}}; bore and stroke is {{convert|83x83|mm|2|abbr=on}}. This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces {{cvt|125|PS|kW|0|order=out}} at 5,500 rpm and {{convert|170|Nm|lbft|0|abbr=on}} 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.) {{cvt|125|PS|kW|0|order=out}} * 2009-2012 Suzuki SX4 (China) {{cvt|131|PS|kW|0|order=out}}
