Ranging in displacement from {{convert|1998|to|2736|cc|L|1|abbr=on|disp=flip}}, the H family was a modern all-aluminum engine with [[dual overhead cam]]s, 24 valves, and [[Fuel_injection#Multi-point_injection|multi-port fuel injection]]. It was co-developed with [[Mazda]] and [[Toyota]], which used a similar design in their [[Mazda K engine#KF|2.0 L KF V6]] and the [[Toyota VZ engine]]. The H family was introduced in 1994 with the H20, but Suzuki, Toyota and Mazda's designs diverged greatly with the former increasing displacement and the latter experimenting with alternative induction technologies and smaller engine sizes. The four-cylinder [[Suzuki J engine|J engine]], which appeared in 1996, shared parts and design with the H family.<ref name=SuzuDL74>{{cite web | url = https://www.suzuki.co.jp/suzuki_digital_library/7_engine/4-j.html | archive-url = | archive-date = | title = ンエンジン紹介: J系 | trans-title = Engine Introduction: J series | language = ja | work = Suzuki Digital Library | publisher = Suzuki Motor Corporation | date = 2021 }}</ref>

==H27A==
The H27A is a modern version of the H25A, displacing {{convert|2736|cc|L|1|abbr=on|disp=flip}}, coming from an {{convert|88x75|mm|in|2|abbr=on}} bore and stroke ([[Variable valve timing|VVT]] added in 2006). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving. It produces {{convert|138|kW|PS hp|0|abbr=on}} at 6,000 rpm and {{convert|250|Nm|lbft|0|abbr=on}} at 3,300 rpm.<ref name=Lumena/>
