Audi introduced the gas versions of the A4 Avant and A5 Sportback with methane engines. Both cars are equipped with an adapted gasoline “turbo four” 2.0 TFSI with a capacity of 170 horsepower and a 7-speed robotized gearbox S-Tronic. The declared gas reserve is from 420 to 455 kilometers on the NEDC cycle.

In addition to natural methane and gasoline, Audi’s propulsion system is capable of consuming synthetic methane. Four gas cylinders hold 17.3 kilograms of compressed methane and are located under the boot floor and in front of the rear axle. The volume of the gas tank was reduced to 25 liters.

All fuel tanks are protected by a special gas-tight polymer coating reinforced with carbon and fiberglass. An epoxy resin is used as a bonding element. The cylinders are separated from the body both from the inside and the outside – the shell is able to protect against damage when traveling through bumps or large stones.

The claimed fuel consumption is low: Audi A4 Avant consumes 3.9 kilograms of gas per 100 kilometers, A5 Sportback – 3.8 kilograms. When the methane level falls below certain values, the engine automatically switches to gasoline. The dynamics were not affected: acceleration from standstill to 100 kilometers per hour takes 8.4 seconds, and the maximum speed of both models exceeds 220 kilometers per hour.

Prices for the wagon Audi A4 Avant g-tron in Germany start from 43,200 euros. Liftback A5 Sportback costs from 45 100 euros. Bitfuel versions are about 5650 euros more expensive than a similar front-wheel drive car with a 150-horsepower gasoline engine. According to the calculations of German journalists, in Europe the gas version will pay for itself after about 160 thousand kilometers.
