Almost all MQB A0-based cars in Europe offer a CNG avatar of the 1.0-litre TSI turbo petrol, the TGI. The German conglomerate says that using CNG helps decrease CO2 emissions by as much as 25 per cent and NOx emissions by up to 75 per cent. Moreover, CNG is far more efficient than diesel, petrol and even LPG: the energy generated by 1kg of CNG is equivalent to 2 litres of LPG, 1.3 litres of diesel and 1.5 litres of petrol. The Volkswagen Group’s 1.0-litre TGI engine produces 90PS of max power between 4,500rpm and 5,800rpm and a maximum torque of 160Nm at 1,900-3,500rpm. This powertrain packs a six-speed manual transmission. The equivalent petrol-powered 1.0-litre TSI is available in two states of tune: 95PS/ 175Nm and 115PS/200Nm, both with manual and DSG automatic options.
