G-Tec’s 1.5l TSI engine has a CNG mode that reduces CO2 emission by 25 percent and returns a natural gas range of 500 km in WLTP cycle
Skoda Octavia G-Tec has been designed to run on compressed natural gas (CNG) as an alternative fuel. The 1.5l TSI engine powering the G-Tec produces 130 PS of maximum power and is capable of returning 500 km range for a tank of CNG. Total storage capacity of 17.33 kg if CNG is distributed in three tanks installed in the underbody of the car. The additional 9-litre petrol tank will support when the CNG range runs out. CO2 emissions reduce by 25 percent while running on CNG, and significantly less nitrogen oxide (NOx) is emitted and no soot particles are produced. Engine efficiency has increased with the use of variable control of the intake valves according to the Miller combustion process. This equates to a consumption rate of 3.4-3.6 kg per 100 km in the WLTP cycle in CNG mode and 21.74 kmpl in petrol mode.
The CNG range of 500 km combined with the 190 km petrol range means a total range of approximately 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. Boot capacity of 455 litres further increases the practicality as CNG tanks are placed in the underbody. Although only for the European market, we do believe G-Tec will be an excellent tech for the Indian market as we gradually increase our CNG fuel adoption.
