The Audi A4 g-tron has received its public premiere this week at the 2015 IAA in Frankfurt.
Although the S4 and the e-tron quattro concept are the main stars at Audi’s stand, let’s not forget they also have on display this compact fellow: A4 g-tron. It’s an interesting choice for those who are in the market for an alternatively-powered vehicle as the g-tron is not your regular A4 since it uses a 2.0 TFSI engine that can run on compressed natural gas (CNG).
In this application, the four-cylinder turbocharged engine develops 170 PS (125 kW) and 270 Nm (199 lb-ft) of torque which should be more than enough for those who value fuel economy. The CNG tanks are installed underneath the floor and can store 19 kg of gas at a pressure of 200 bars. In terms of gas consumption, Audi mentions that for every 100 km the vehicle will need less than 4 kg while the total range when running on CNG stands at a very decent 310 miles (500 km).
Once you run out of compressed natural gas, the gasoline tank will last for about 280 miles (450 km), so the Audi A4 g-tron is a viable solution if you take longer trips.
