1G engine series consists of four types of 2-liter, in-line, 6-cylinder gasoline engines for passenger cars, with different performance characteristics to meet diversified market demands. These engines are already put into mass production. The original engine - 1G-EU - is a compact and light weight 2-valve OHC engine with the maximum power 77 kW/5200 rpm. The 1G-GEU is a 4-valve DOHC engine developed on the basis of the 1G-EU engine, with a higher performance and a higher power of 103 kW/6200 rpm. The 1G-GZEU is a mechanical supercharging type engine based on the 1G-GEU, with a remarkably improved performance in the low and medium engine speed ranges, and the highest power of 110 kW/6000 rpm. The 1G-GTEI! is a turbocharging type engine also based on the 1G-GEU, with a markedly improved performance in the medium and high speed ranges, and the high power of 136 kW/6200 rpm. A number of new technologies were introduced on development of these engines.
