Toyota GR engine

The Toyota GR engine is a gasoline, open-deck, piston V6 engine family. The series has a 60 degree die-cast aluminium block and aluminium DOHC cylinder heads, with four valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain and a cast aluminium lower intake manifold. Some variants use multi-port fuel injection, some use D4 direct injection, and others combine direct and port injection as in the D4-S system. The GR series replaced the earlier MZ V6 and JZ inline-six, and in light trucks the VZ V6. The 1GR-FE is a 4.0 litre, 3,956 cc version designed for longitudinal mounting in rear-wheel-drive and four-wheel-drive pickups, with a bore and stroke of 94 by 95 millimetres and variable valve timing on the intake cam. The 2GR-FKS is a 3.5 litre, 3,456 cc engine that first appeared in the 2015 Lexus RX 350. In the Transport Atlas it represents Toyota modern V6 family.
