The 4th generation Skoda Octavia lineup has got the G-TEC variant, which is claimed to emit 25% less CO2 in CNG mode, when compared to running on petrol.
The Octavia G-TEC packs a 1.5-litre TSI motor that can run on natural gas with an output of 96 kW (130 hp). This type of fuel burns more cleanly, resulting in the aforementioned lower CO2 emissions and significantly less NOx (Nitrogen Oxide) emissions in CNG mode. The engine is efficient too, thanks to, among other things, variable control of the intake valves according to what is known as the Miller combustion process.
Boasting a CNG capacity of 17.33 kg (38.2 lbs), the Octavia G-TEC claims a range of up to 500 km (310 mi) in the WLTP cycle in natural gas mode. There’s also a 9-litre petrol tank, which helps take the vehicle to a further 190 km (118 mi), Skoda said. Switching between CNG and petrol mode happens automatically without driver intervention.
The vehicle only accesses the petrol in certain situations, such as when the engine is started after the CNG has been topped up, when the outside temperature is below -10 degree Celsius, or when the gas tanks are so empty that the pressure drops below 11 bar.
The G-TEC models feature a specific layout in the Virtual Cockpit and can also be identified by a badge at the rear. The Octavia G-TEC will be available in Europe later this year.
