Mladá Boleslav, June 26, 2020 – The new ŠKODA OCTAVIA G-TEC is designed to run on environmentally friendly compressed natural gas (CNG). The OCTAVIA G-TEC is equipped with a 1.5 TSI, providing 96 kW (130 PS), and achieves a range of 500 km * in the WLTP cycle when used only with this type of fuel. Three tanks installed in the base store a total of 17.33 kg of CNG. A 9-liter fuel tank ensures mobility in regions without an adequate refueling infrastructure. The new OCTAVIA G-TEC will be launched across Europe this fall.
The 1.5 TSI of the OCTAVIA G-TEC is designed to operate on natural gas and has a power of 96 kW (130 PS). This type of fuel burns cleaner, resulting in CO emissions2 CNG mode emissions which are approximately 25% lower than those running on petrol; in addition, much less nitrogen oxide (NOX) is emitted and no soot particles are produced. The engine is very efficient, thanks, among other things, to the variable control of the intake valves according to what is called the Miller combustion process. This allows consumption of 3.4 to 3.6 kg per 100 km in the WLTP cycle in CNG mode and 4.6 l per 100 km in petrol mode.
With a CNG capacity of 17.33 kg, the OCTAVIA G-TEC has a range of 500 km * in the WLTP cycle in natural gas mode. When using petrol in its 9-liter tank, the OCTAVIA G-TEC can travel an additional 190 km *, which gives it a total autonomy of approx. 700 km *. Switching between CNG and petrol mode takes place automatically without driver intervention.
The vehicle accesses the fuel supply only in certain situations, for example when the engine is started after filling the CNG, when the outside temperature is below -10 degrees Celsius, or when the fuel tanks are so the pressure drops below 11 bar. The OCTAVIA G – TEC has a specific layout in the virtual cockpit and can be easily identified by a badge at the rear. The tailgate trunk can hold 455 l, the COMBI trunk capacity is 495 l.
In CNG, CO mode2 emissions are 25% lower than those of a conventional petrol engine, even when using natural gas. By using 20% bio-CNG, as is common today in Germany, for example, the car’s carbon footprint can be improved by 35 to 40%. The use of fuel blends with an even higher percentage of bio-CNG, from plant residues and biological waste, leads to improvements of up to 90%. This means that travel under these circumstances is almost climate neutral. Total climate neutrality can be achieved by using synthetic methane, which is produced with green electricity in a gas conversion process. However, this procedure is still under development.
