The H family is a line of automobile 60° V6 engines from Suzuki. Ranging in displacement from 2.0 to 2.7 L (1,998 to 2,736 cc), the H family was a modern all-aluminum engine with dual overhead cams, 24 valves, and direct fuel injection. It was co-developed with Mazda and Toyota, which used a similar design in their 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.
