Updated VW and Seat TGI models: a bit more CNG, a lot less petrol range
CNG lovers, rejoice: after months of WLTP-induced uncertainty, VW and Seat finally announce the TGI models are back. Better still, they have been improved - but there is a flip side to the medal.
The VW Polo TGI has gained a third gas tank to improve its CNG range to 368 km. The Golf TGI swaps its 1.4 for the new, more efficient 1.5 and also gets an extra CNG tank, resulting in a rather comfortable 422 km of range. Once these tanks are depleted, the Polo and Golf TGI switch to petrol.
And that's where things change for the worse: the advent of a third CNG tank has reduced the petrol tank to less than 10 litres. That means that once you run out of CNG, you have about 130 km left to make it to a filling station.
Before the update, the TGI models offered a combined range of 1,000 km or more thanks to the standard-sized petrol tank. The new models strand after 500-odd km.
Seat Ibiza, Arona and Leon TGI
As the Seat Ibiza, its crossover derivative Arona and the Leon use the same platform as the VW Polo and Golf, respectively, they undergo the same update.
In April 2018, the brand announced it would lead CNG development in the VW group. "Vehicular natural gas has great business potential for the automotive industry, and we want this to be technology made in Spain,” Seat president Luca de Meo said during last year's annual congress of Gasnam.
Seat’s portfolio of CNG cars is the largest mong all European automakers. CNG drivers can choose between the Mii, Ibiza, Leon and Arona - the first crossover to run on natural gas.
The main advantages of CNG are lower CO2, NOx and PM emissions and a considerable fuel cost reduction. That is why CNG is sometimes dubbed the new diesel.
