Audi RS6 Avant, Audi S3 Sportback, Audi RS Q3, Audi A3 e-tron.
The g-tron is powered by a specially-developed version of the conventional A3’s 1.4-liter TSI four-cylinder engine modified to run on Audi’s own e-gas, regular Compressed Natural Gas (CNG) or unleaded gasoline.
According to Audi, the 1.4-liter turbocharged unit develops 109hp (110PS) and 200Nm (147 lb-ft) of peak torque, regardless of the fuel used. The five-door model completes the standards sprint to 100km/h (62mph) in 11.0 seconds before it tops out at 190km/h (118mph). It consumers on average less than 3.5 kilograms per 100 km of CNG or Audi e-gas, while in gasoline mode, it emits less than 95g of CO2 per km.
