The new ŠKODA OCTAVIA G-TEC is designed to run on environmentally friendly CNG. It is fitted with a 1.5 TSI engine with an output of 96 kW (130 PS). The engine is very efficient, thanks to, among other things, variable control of the intake valves according to what is known as the Miller combustion process. This enables 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.
Boasting 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 making use of the petrol in its 9-litre tank, the OCTAVIA G-TEC can cover a further 190 km, giving it a total range of approx. 700 km. Switching between CNG and petrol mode happens automatically without driver intervention.
The vehicle only accesses the petrol fuel supply in certain situations, such as when the engine is started after the CNG has been topped up, when the outside temperature is below -10 degrees Celsius, or when the gas tanks are so empty that the pressure drops below 11 bar. The OCTAVIA G TEC features a specific layout in the Virtual Cockpit and can be easily identified by a badge at the rear. The hatchback’s boot can hold 455 l, the COMBI’s boot capacity is 495 l.
In CNG mode, CO2 emissions are 25% lower than those of a conventional petrol engine, even when using natural gas. By using 20% bio-CNG, as is currently common in Germany, for example, the car’s carbon footprint can be improved by as much as 35 to 40%. Using fuel mixtures with an even higher percentage of bio-CNG, from plant residues and biological waste, leads to improvements of up to 90%. This means that journeys under these circumstances are almost climate-neutral. Full climate neutrality can be achieved by using synthetic methane, which is produced with green electricity in a power-to-gas process, a procedure that is still under development.
The new OCTAVIA G-TEC will be launched across Europe this autumn.
