The '''Honda G-series engine''' is a family of slanted [[Straight-five engine|inline-five cylinder]] [[gasoline engine]]s. The engine family features a [[SOHC|single overhead cam]] layout with 4 valves per cylinder. The engine's [[Engine displacement|displacement]] varied from {{convert|1996|cc|L CID|1|abbr=on|order=flip}} to {{convert|2451|cc|L CID|1|abbr=on|order=flip}}. The G-Series was originally used in the 1989 [[Honda Vigor]], [[Honda Rafaga]], [[Honda Ascot]] and [[Honda Inspire]] before being carried over to the Vigor's successor; the [[Acura TL]], which used the G-Series family of engines from 1995 to 1998 in North America, and continued use in the [[Japanese domestic market|JDM]] [[Honda Saber]] until 1998 as well.
