Natural gas engines (TGI)

World premiere II in Vienna: The new natural gas high-tech engine TGI 1.5 Evo

Natural gas engines (TGI)

Thanks to their high efficiency and low emissions (no particulate emissions, carbon neutral depending on fuel source), natural gas engines are currently experiencing a big upsurge. Volkswagen offers a number of models with natural gas engines. They are designated as “TGI” powertrains. In the spring of 2018, Volkswagen presented a natural gas engine of the future, the 1.5 TGI evo. The 1.5-litre direct injection engine with a VTG (variable turbine geometry) turbocharger is based on the new 1.5 TSI ACT BlueMotion petrol engine that has already been introduced. Like the petrol version, the natural gas engine, which has an identical power output of 96 kW / 130 PS, uses the efficient TSI/TGI Miller combustion process.

    Volkswagen gives some gas with new TGI models

    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 kilometres further in pure CNG mode than its predecessor. The gain in range in the Golf TGI is up to 80 kilometres. In the Golf, a new 1.5 litre TGI four-cylinder engine with 96 kW / 130 PS ensures that none of the driving pleasure is lost. Driving with natural gas significantly reduces CO2 emissions because the combustion of CNG generally produces less CO2. An even better CO2 balance can be achieved by fuelling with biomethane or e-gas. Biomethane is extracted from plant residues; e-gas is produced from surplus green energy (power-to-gas), which are added to the fuels.

The specified fuel consumption and emission data does not refer to a single vehicle and is not part of the offer but is only intended for comparison between different types of vehicles. Additional equipment and accessories (additional components, tyre formats, etc.) can alter relevant vehicle parameters such as weight, rolling resistance and aerodynamics, affecting the vehicle's fuel consumption, power consumption, CO2 emissions and driving performance values in addition to weather and traffic conditions and individual driving behavior.

Further information on official fuel consumption data and official specific CO2 emissions for new passenger cars can be found in the "Guide to fuel economy, CO2 emissions and power consumption for new passenger car models", which is available free of charge from all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, D-73760 Ostfildern, Germany and at www.dat.de/co2.
