Volkswagen has completely overhauled its natural gas models and is equipping its Polo and Golf TGI with a third natural gas tank. This allows the Polo TGI to now travel up to 60 kilometers further in pure CNG mode than its predecessor. The gain in range in the Golf TGI is up to 80 kilometers. In the Golf, a new 1.5 liter TGI four-cylinder engine with 96 kW/130 PS ensures that none of the driving pleasure is lost. The nw natural gas-powered TGI models are available to order now

Volkswagen has equipped its natural gas models of the Polo TGI and Golf TGI with a third natural gas tank made of specially coated, high-strength steel. The Golf’s tank has a volume of 23 liters and increases the total CNG tank volume to 115 liters, or 17.3 kg respectively, which offers a range of up to 422 kilometers in WLTP.

On the Polo with 1.0 three-cylinder engine (66 kW / 90 PS) the additional tank carries 16.5 litres and extends the natural gas storage to 91.5 liters in total, or 13.8 kg respectively, meaning that the Polo can travel up to 368 kilometers on CNG in WLTP. As a back-up, both models come with a petrol tank – albeit a much smaller version.

For improved driving dynamics and efficiency, the Golf TGI’s new 1.5 liter four-cylinder engine is powerful, efficiency and environmentally friendly. Proof of this comes from its fuel consumption of just 3.6 kg – 3.5 kg natural gas over 100 kilometers, and CO2 emissions of just 98–95 g/km. This engine uses the innovative TGI Miller combustion process with a high compression ratio of 12.5:1, to increase efficiency and decrease CO2 emissions. A turbocharger with variable turbine geometry increases the boost pressure, adding more air into the cylinders. This allows the 1.5-litre TGI engine to accelerate powerfully at any time from low speeds.
