The Toyota GR engine family is a gasoline, open-deck, piston V6 engine series. The GR series has a 60° die-cast aluminium block and aluminium DOHC cylinder heads. This engine series also features 4 valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain,[1] and a cast aluminium lower intake manifold. Some variants use multi-port fuel injection, some have D4 direct injection, and others have a combination of direct injection and multi-port fuel injection or D4-S.
The GR series replaces the previous MZ V6 and JZ inline-6, and in the case of light trucks the VZ V6.
Note: Power ratings have changed due to SAE measurement changes in 2005 (for the 2006 model year). Toyota rates engines on 87 pump octane, Lexus rates engines on 91 pump octane.
