Toyota G engine

The Toyota Motor Corporation G-family engine is a family of straight-6 piston engines produced from 1979 to 2008. It is notable in that only a single displacement, 2.0 L (1,988 cc), was produced in this series. Initially belt-driven OHC non-interference engines (except the VVT-i version which is an interference engine), multivalve DOHC (except the 1G-EU SOHC 12 valve engine) and variable valve timing were added later during the production run. The 1G-GEU was Toyota's first mass produced four-valve twincam engine. A prototype version of the 1G-GEU called the LASREα–X, featuring twin-turbos, variable valve timing and intake as well as variable displacement, was fitted to the Toyota FX-1 show car at the 1983 Tokyo Motor Show. It showcased a number of technologies which were later to become commonplace. This engine was designed around the new LASRE technology for lighter weight – such as sintered hollow camshafts. These engines were used as a lower-displacement alternative to the more upmarket M family and JZ family straight-sixes. For ten months (in 1967-1968), Toyota also offered Hino's GR100 engine as the "Toyota G" in the shortlived Briska light truck.
