CNG as a fuel – more energy fewer emissions
Volkswagen’s natural gas strategy continues to gain ground: only recently available to order, the Polo TGI2) and Golf TGI3) are now joined by the Golf Variant TGI1) with eco-friendly natural gas engine.
ŠKODA VISION X
As the first ŠKODA, this concept has multiple propulsion systems, giving you three ways to get started: a combination of a CNG and gasoline-powered engine, and a built-in electric motor that reduces CO2 emissions to 89 g / km.
Wolfsburg, 21 February 2018 – New partnerships, new vehicle model, increased registration figures: The Volkswagen Group and its industrial partners from the areas of gas supply, grid operation and filling stations are once again continuing their successful brand and information offensive in the year 2018. Since the start of the cross-brand campaign in spring 2017, the campaign alliance has succeeded in significantly enhancing the status of CNG (Compressed Natural Gas) for individual mobility in Germany. The current registration figures from the German Federal Motor Transport Authority confirm that CNG engines are currently the type of power unit experiencing the most robust growth. »read more

Wolfsburg, 7 November 2017. The Volkswagen Group and its industry partners from the areas of gas supply, grid and filling station businesses have drawn a positive provisional conclusion from their joint commitment to the expansion of CNG mobility. Just a few months after the start of the current information offensive with the CNG Mobility Days in Hamburg, the campaign alliance succeeded in achieving a significant increase in the status of CNG (Compressed Natural Gas) for individual mobility. Since July 2017, the number of newly registered CNG vehicles in Germany on a month-for-month basis increased significantly compared to the previous year. At the launch of the CNG Mobility Days on 7 and 8 November 2017 in Essen, the companies announced further steps for their initiative. The latest models developed by the Volkswagen Group to run on CNG are being presented in Essen in the form of the VW Polo TGI and the SEAT Ibiza 1.0 TGI. Furthermore, the Volkswagen Group rewards the move to a low CO2 CNG vehicle with a special bonus. The industry circle for CNG Mobility recently gained additional momen-tum when biomethane manufacturer VERBIO joined the group. » read more

What is CNG?
Natural gas – also known as CNG (Compressed Natural Gas) – is by nature a particularly pure fuel. The main component is methane with the chemical composition CH4. Each molecule only contains one carbon atom. Even though natural gas is a fossil fuel, CNG consequently releases around 25 percent less CO2 than conventional fuels when it undergoes combustion in an engine. CNG also burns more cleanly than petrol or diesel – virtually free of fine dust and with significantly lower proportions of other emissions that are harmful to the climate. And because CNG with 13.0 kWh/kg has a higher energy density than petrol (12.0 kWh/kg) and diesel (11.8 kWh/kg), a CNG vehicle not only cuts down emissions that are harmful to the environment, it also saves money at the filling station.
CNG creates mobility
When searching for alternatives to conventional fuels for automobiles, the focus is increasingly falling on three letters: CNG. They stand for “Compressed Natural Gas”. The principal manifestation of CNG is natural gas. This fuel is used in millions of households for providing heat, for producing hot water and for cooking. CNG is equally suitable in everyday practical terms as a fuel for mobility. Almost 100 000 automobiles are already driving on German roads alone powered by CNG. They generate a significantly lower level of emissions compared with petrol or diesel vehicles with similar driving performance.
Their owners have access to a nationwide network of around 920 CNG filling stations. These are connected to the nationwide gas supply grid of around 500 000 kilometres. CNG is therefore available at any time throughout the country. The Volkswagen Group has joined forces with industrial partners in the areas of generation, supply and filling-station operation to increase the number of CNG automobiles tenfold in Germany by the year 2025 and to expand the filling-station grid to around 2000 stations. The brands of the Volkswagen Group are launching effective initiatives for this offensive with new CNG models, which also offer economic advantages as a result of their environmental benefits. This is because both CNG as a sustainable fuel and the automobiles powered by this fuel benefit from tax breaks. Yet CNG is not simply a cost-effective alternative to conventional fuels. It is also particularly future-proof. It comprises a continuously growing proportion of carbon-neutral biogas made from sustainably reproducing raw materials. CNG can also be mixed with hydrogen, which is climate neutral and can be generated in unlimited amounts using electricity from renewable sources.
natural gas mobility
The Volkswagen Group, operators of CNG filling stations and gas network providers have signed a Memorandum of Understanding with which the initiators are committed to expanding CNG mobility. CNG stands for “compressed natural gas” and can be natural gas or renewable energy from eco-electricity. The signatories underpin the goals of the “Round Table for Natural Gas Mobility” launched by the Federal Ministry of Economics in 2016, which was attended by representatives of vehicle manufacturers, the gas industry and service station operators as well as representatives of key retail, fleet and public sector customers.
the vehicle range
Volkswagen has been on the market since 2002 with CNG models. The current offering of the Volkswagen Group brands includes a diverse vehicle portfolio in numerous segments. It ranges from economical urban mobility to premium models and also includes state-of-the-art and efficient natural gas vehicles from the subsidiary TRATON GROUP. The Volkswagen Group underscores its commitment to expanding CNG mobility by developing new, ultra-low-emission and fuel-efficient natural gas engines, as well as continually expanding its brands’ vehicle program, adding further attractive CNG models.
with industry partners
For the Volkswagen Group, the expansion of CNG mobility is an important building block of its realignment of the drive portfolio decided in the context of the “TOGETHER – Strategy 2025” future program. The communal character is also reflected in the Volkswagen Group’s concerted offensive with gas network operators and operators of CNG filling stations. With an attractive range of vehicles and a comprehensive as well as high-performance infrastructure, Volkswagen and its industrial partners are creating ideal conditions to make an immediate and simultaneously sustainable contribution to reducing emissions.
