Audi is extending its range of particularly fuel-efficient, low-emission ultra models in the A3 car line with both gasoline and diesel powertrains.

The three-door Audi A3 1.4 TFSI ultra, with a top speed of 220 km/h (137 mph) and acceleration from 0 to 100 km/h (62 mph) in 8.1 seconds, offers fuel consumption of 4.7 liters of fuel per 100 kilometers (50.0 US mpg) over the combined cycle; this equates to CO2 emissions of 109 g/km (175.4 g/mi).

The new offering of a 1.4?liter TFSI gasoline engine is available in combination with either a manual 6?speed transmission or a 7?speed S tronic. The power unit with cylinder-on-demand technology is also available in all four body versions of the A3 car line—as a three?door model, a five?door Sportback, a Sedan and as a Cabriolet.

Audi also offers an A3 ultra version with 1.6 TDI engine. This power unit has already been available for the three?door version and the Sportback since 2013. In future, the A3 Sedan can likewise be outfitted with this 81 kW (110 hp) diesel engine.

Fuel consumption for the diesel is 3.3 liters of fuel per 100 kilometers (71.3 US mpg), with 88 grams of CO2 per kilometer (141.6 g/mi).

Audi has already launched 12 ultra models with TDI and TFSI engines in the A4, A5, A6 and A7 car lines, and now has a total of 22 ultra models in its range.

Alongside the e-tron plug-in hybrid models and the gas-powered g-tron cars, the ultra fleet is now the third production concept implemented by Audi for providing forms of sustainable mobility suited to everyday use.
