The H family is a line of 60° V6 automobile engines from Suzuki. Ranging in displacement from 2.0 L to 2.7 L, the H family was a modern all-aluminum engine with dual overhead cams, 24 valves, and multi-port fuel injection. It was co-developed with Mazda, which used a similar design in their 2.0 L KF V6. The H family was introduced in 1994 with the H20, but Suzuki and Mazda's designs diverged greatly with the former increasing displacement and the latter experimenting with alternative induction technologies and smaller engine sizes.


The H20A displaces 2.0 L (1,998 cc); bore is 78.0 mm (3.1 in) and stroke is 69.7 mm (2.7 in). With a 9.5:1 compression ratio, it produces 100 kW (136 PS) at 6,500 rpm and 172 N·m (127 lb·ft) at 4,000 rpm.[1]



The H25A displaces 2.5 L (2,495 cc); bore is 84.0 mm (3.3 in) and stroke is 75.0 mm (3 in) and produced 118 kW (160 PS) when first introduced.[2] With a 9.5:1 compression ratio, it produced 106 kW (144 PS) at 6,500 rpm and 203 N·m (150 lb·ft) at 3,500 rpm on its introduction, with a 2001 update increasing this to 116 kW (158 PS) and 213 N·m (157 lb·ft).[3] It is also being considered and used for various ultra-light aircraft propulsion systems.



The H27A is a bored out version of the H25A, displacing 2.7 L (2,736 cc, coming from an 88 mm bore and 75 mm stroke). It produces 135 kW (184 PS) at 6,000 rpm and 250 N·m (184 lb·ft) at 3,300 rpm.[3]
