Audi e-gas / Audi g-tron

Audi A4 Avant g-tron

In addition to TFSI and TDI engines, Audi is increasingly banking on alternative drive systems. One focal point here is the g-tron models – A3 Sportback g-tron, A4 Avant g-tron and A5 Sportback g-tron. They operate mainly on compressed natural gas (CNG). Thanks to the synthesized Audi e-gas they enable virtually CO2-neutral mobility.

    TechDay Combustion Engine Technology

    V engines from the Four Rings have been around for 29 years – the 3.6-liter eight-cylinder engine made its debut in the Audi V8 in 1988. A 2.8-liter V6 followed two years later, in the Audi 100. Things then really took off in the 1990s: in 1997 the world’s first V6 TDI appeared with the 2.5 TDI, followed in 1998 by the V8 TDI with a displacement of 3.3 liters. And in 2000 the V6 biturbo with 2.7 liters’ displacement was a very special highlight: the 279 kW (380 hp) and 440 Nm (324.5 lb-ft) of torque driving the Audi RS 4 Avant set the bar at a totally new level in the midsize category. Today, Audi uses V6 and V8 engines in all models based on the modular longitudinal platform, namely in the Audi A4, A5, A6, A8, Q5 and Q7 series. The V6 units – gasoline as well as diesel engines – operate with a displacement of 3.0 liters, and 4.0 liters in the case of the V8 engines. Their power output ranges from 160 kW (218 hp) to 445 kW (605 hp). The new 2.9 liter V6 engine in the Audi RS 5 (combined fuel consumption: 8.7 l/100 km (27.0 US mpg); combined CO2 emissions: 197 g/km (317.0 g/mi)) is a special case. Owing to the increased power and therefore greater stress on the engine, the displacement was reduced by 0.1 liters. Further information on official fuel consumption figures and the official specific CO2 emissions of new passenger cars can be found in the “Guide on the fuel economy, CO2 emissions and power consumption of all new passenger car models,” which is available free of charge at all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen, Germany (www.dat.de).

    Alternatives for the midsize category: Audi A4 and A5 now available to order as g-tron

    Audi is offering its customers two sustainable alternatives in the midsize category: the new A4 Avant g-tron and the new A5 Sportback g-tron. Both models are powered by a bivalent 2.0 TFSI engine developing 170 hp. Like the A3 Sportback g-tron that is already on the market, they can run on a choice of the climate-friendly fuel Audi e-gas, conventional CNG (compressed natural gas) or gasoline. Customers can now order both models from dealers. A4 Avant g-tron: CNG consumption in kg/100 km: 4.4 - 3.8*; combined fuel consumption in l/100 km: 6.5 - 5.5*; combined CO2 emissions in g/km (CNG): 117 - 102*; combined CO2 emissions in g/km (gasoline): 147 - 126* A5 Sportback g-tron: CNG consumption in kg/100 km: 4.2 - 3.8*; combined fuel consumption in l/100 km: 6.3 - 5.6*; combined CO2 emissions in g/km (CNG): 114 - 102*; combined CO2 emissions in g/km (gasoline): 143 - 126* A3 Sportback g-tron: CNG consumption in kg/100 km: 3.6 - 3.3*; combined fuel consumption in l/100 km: 5.5 - 5.1 *; combined CO2 emissions in g/km (CNG): 98 - 89*; combined CO2 emissions in g/km (gasoline): 128 - 117*

    Complete Commitment to Renewable-Energy Revolution in Cars

    The wheels of a dark green MAN-TGX truck tractor with semi-trailer very slowly start to move. It is just after nine p.m. and the sound of the 16.2-liter V8 engine fills the ice-cold air. In the days to come, this 680-horsepower engine must not only ensure the towing of nearly 150 metric tons. It also has to meet great expectations by helping pave a path to the mobility of tomorrow.
