Volkswagen Golf TGI now available with natural gas drive again

October 24, 2020. The new Golf is now also available with an environmentally-friendly natural gas drive: the Golf TGI is equipped with a powerful 1.5-litre four-cylinder engine with 96 kW/130 PS and three natural gas fuel tanks. The tanks are integrated into the underbody and permit a range of around 400 kilometers (WLTP) in pure natural gas mode. The engine of the quasi-monovalent drive system is powered primarily with compressed natural gas (CNG), but can also run on petrol. A reduced-capacity petrol tank serves only as a reserve, but ensures additional range.

Drivers of natural-gas-powered vehicles benefit from comparatively low fuel prices in many countries. Volkswagen is now also offering the new Golf as a TGI model with a natural gas drive and increased range – in October the Golf Variant will also be available as a TGI. The total CNG tank capacity is currently 115 liters or 17.3 kg and permits a driving radius of a good 400 kilometers in the WLTP cycle. The Golf TGI is also equipped with a petrol tank with a useful capacity of 9 liters – this is essentially a reserve tank in case the natural gas should run empty.

For driving dynamics and efficiency, the Golf TGI comes with a 1.5-litre four-cylinder petrol engine. This powerful engine is both efficient and environmentally friendly, as also demonstrated by its WLTP fuel consumption of just 4.3–4.1 kg of natural gas per 100 kilometers in combination with CO2 emissions of only 117–111 g/km. The new 1.5 l TGI engine in the Golf operates according to the innovative Miller cycle principle, a combustion process that achieves low carbon emissions thanks to its high efficiency and a compression ratio of 12.5:1. At the same time, a turbocharger with variable turbine geometry increases the charge pressure and supplies more air to the cylinders. This allows the Golf TGI to accelerate powerfully from low engine speeds at any time.

Driving with natural gas significantly reduces carbon emissions. Compared to petrol or diesel, natural gas contains a significantly higher amount of energy and has lower carbon content. This means that driving in CNG mode produces around 25 percent fewer carbon emissions than with petrol. Refueling with biomethane or e-gas results in an even better carbon balance.
