Volkswagen gives some gas with new TGI models
Volkswagen has completely overhauled its natural gas models and is equipping its Polo and Golf TGI with a third natural gas tank.
This allows the Polo TGI to now travel up to 60 kilometres further in pure CNG (compressed natural gas) mode than its predecessor. The gain in range in the Golf TGI is up to 80 kilometres.
In the Golf, a new 1.5 litre TGI four-cylinder engine with 130 PS which uses the innovative TGI Miller combustion process to increase efficiency and decrease emissions: 3.6 kg natural gas over 100 kilometres, and CO2 emissions of just 98–95 g/km.
The Golf’s third tank has a volume of 23 litres and increases the total CNG tank volume to 115 litres (17.3 kg) which offers a range of up to 422 kilometres.
On the Polo with 1.0 three-cylinder engine with 90 PS the additional tank carries 16.5 litres and extends the natural gas storage to 91.5 litres in total (13.8 kg), meaning that the Polo can travel up to 368 kilometres on CNG.
As a back-up, both models come with a petrol tank, albeit a much smaller version.
