New Volkswagen Golf Variant TGI natural gas model now available to order

March 14, 2019. Volkswagen’s natural gas strategy continues to gain ground: only recently available to order, the Polo TGI and Golf TGI are now joined by the Golf Variant TGI1 with eco-friendly compressed natural gas (CNG) engine. The new model now boasts three natural gas tanks – instead of just two as before – once again increasing the already long range of the CNG drives. And there’s no need to compromise on space either to accommodate the three tanks on-board, as the natural gas tanks are integrated as a space-saving underfloor solution. At the same time, the additional tank increases the range in natural gas mode by up to 80 kilometers compared to its predecessor. You’ll now also reach your destination faster, as the bonnet conceals an overhauled, powerful 1.5-litre four-cylinder engine with 96 kW (130 hp). This engine is primarily powered with compressed natural gas – the petrol tank is smaller as a result and thus only serves as a backup.

Thanks to the TGI Miller combustion process and the variable turbine geometry (VTG) of the turbocharger, the Golf Variant TGI’s 1.5-litre four-cylinder petrol engine is even more efficient and responsive than its predecessor. It delivers 96 kW (130 PS) and boasts a torque of 200 newton meters. With the petrol tank reduced in size to 9 liters (for a Golf Variant TGI, which corresponds to a range of approximately 200 kilometers) and now serving merely as a backup, this is referred to as a quasi-monovalent drive concept. In other words, the range with natural gas alone has increased by around 80 kilometers, enabling routes of up to 440 kilometers (based on WLTP) with natural gas alone.

The three natural gas tanks have a combined volume of 115 liters, which corresponds to a total weight of 17.3 kilograms. The tanks are made from carbon fiber-reinforced plastic (CFRP) or from metal.
