The Honda G-series engine is a family of slanted inline-five cylinder gasoline engines; the engines are SOHC with 4 valves per cylinder. They were originally used in the 1989 Honda Vigor, Honda Rafaga, Honda Ascot and Honda Inspire. They carried over to the Vigor's successor the Acura 2.5TL, which ran from 1995-1998 in North America, and the Honda Saber in Japan.
Some people colloquially refer to an F-Series block (found in Accords) with an H-Series head (found in Preludes) as a "G-series" engine. This combination of an Accord bottom end with a Prelude head has nothing in common with the actual G-series engine. The engine is longitudinally mounted and resembles an F-Series single cam engine (found in early Accords) with an extra cylinder on it and a shorter stroke.
