Audi will showcase in Geneva next week the A3 Sportback g-tron together with the e-tron plug-in hybrid variant.

The g-tron has two gas tanks and a regular 1.4 TFSI engine producing 110 HP (81 kW) and 200 Nm (147 lb-ft) of torque, enough for a 0-62 mph (0-100 km/h) in 11 seconds and a top speed of 118 mph (190 km/h). The performances are the same whether it runs on gasoline or on gas.

Those tanks can carry up to 7 kg (15.3 lbs) of CNG at a max pressure of 200 bar and are installed under the boot floor. Audi says it has a fuel consumption of 3.5 kg / 100 km when running on gas and a range of 242 miles (400 km). These tanks are made from carbon fiber-reinforced polymer and each tank weighs 27 kg (59.5 lbs) when full.

Using gasoline provides a range of 559 miles (900 km), while the total range stands at 807.7 miles (1,300 km). The Audi A3 Sportback g-tron benefits from an electronic gas pressure regulator which can reduce the high pressure of the gas flowing from the cylinders. During low-speed driving it enables a low-pressure gas, but when greater performance is required it allows for a high-pressure flow.

Full details are available in the attached press release.
