Audi A3 g-tron revealed

Audi has revealed the A3 g-tron Sportback ahead of the Geneva Motor Show, an A3 that runs on Compressed Natural Gas (CNG) and petrol. The A3 g-tron is powered by a tweaked version of Audi’s 1.4 litre TSI petrol engine which can run on both -gas and petrol, with the A3 g-tron normally using the petrol just for start-up and switching over to e-gas as soon as it’s running. Audi has provided two fillers under a common fuel flap – one for e-gas and one for petrol – with the A3 g-tron producing a total of 108bhp with the dual-fuel setup, enough to power the A3 g-tron to 62mph in 11 seconds.

Which, of course, he did. But Vettel didn’t have it all his own way, at least from the off, with Nico Rosberg taking his Mercedes past Vettel and Hamilton pushing his past Alonso’s Ferrari.
