Its EVs aren't quite ready to save the planet yet, so Audi is strengthening its lineup with two new g-tron models based on the A5 5-door coupe and the A4 wagon, which can run on the brand's "climate friendly fuel" e-gas, normal CNG or regular gasoline.
Just like the A4 and A5 g-tron, which have been available for some time now, the newcomers pack a 2.0 TFSI turbocharged mill that produces 170 S and 270Nm (199 lb-ft) of torque.
Without crazy launch control or quattro, these aren't particularly fast cars, requiring 8.5 seconds to reach 100 km/h. The top speed is 226 km/h (140 mph) in the case of the wagon and 223 km/h (139 mph) for the A5 Sportback.
Over the standard driving cycle, the A4 Avant g-tron with S tronic (7-speed DCT) uses 3.8 kilograms of gas per 100 kilometers, with CO2 emissions of 102 grams per kilometer. When in gasoline mode, the figure increases to 5.5 liters per 100 kilometers (42.8 US mpg) and 126 grams of CO2 per kilometer.
The are plenty of other cars in Germany that run on compressed natural gas. Some are quite elegant, though nobody matches the premium interior feel of a brand new Audi. And thanks to all the fuel-saving tech, these cars have a very high range for non-diesels: up to 950km (590 miles) on both tanks.
The extra fuel is stored in tanks that are made from carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GFRP). They store 19 kilograms (42 lbs) of gas at a pressure of 200 bars. When the pressure drops below 10 bars, the system automatically switches to using gasoline. Despite this, both models have a full-size luggage compartment. There are 415 liters (14.7 cu ft) of luggage capacity in the A4 Avant g-tron, and 390 liters (13.8 cu ft) in the A5 Sportback g-tron.
Both models are available through special order in Germany and cost €40,800 for the A5 Sportback g-tron or €40,300 in the case of the more practical Avant. They will enjoy an official presentation during the Frankfurt Motor Show in September.
