    Since 2010, the 2.5 TFSI has been voted “International Engine of the Year” in its class for seven consecutive years. Now, Audi presents a new version of the successful power unit. The turbo engine which drives the new RS 3 Sedan* and the facelifted RS 3 Sportback* is the most powerful series-production five-cylinder engine on the world market.

    The five-cylinder achieves a good 17 percent more output from the unchanged displacement of 2,480 cc – 294 kW (400 hp) means a specific value of 161.3 hp per liter. The maximum torque of 480 Nm (354.0 lb-ft) is available from 1,700 rpm and remains constant up to 5,850 rpm. The new Audi TT RS Coupé thus accelerates from 0 to 100 km/h (62.1 mph) in 3.7 seconds; the Roadster takes 3.9 seconds. Standard top speed is a governed 250 km/h (155.3 mph). Audi will raise the top speed to 280 km/h (174.0 mph) upon request.

    A central innovation in the 1.8 TFSI is the addition of indirect fuel injection. Indirect injection supplements FSI direct fuel injection in the part-load range. This lowers fuel consumption and reduces particulate emissions to within the limits of the future Euro 6 standard. FSI fuel injection is active when starting and at higher loads. The valve control system has been given greater operating freedom. The Audi valvelift system, which adjusts the lift of the valves as needed, is active on the exhaust side; the camshafts can also be adjusted.

  • Superb: the W12 in the Audi A8 L

    W12

    In the A8 L, Audi’s top-of-the-line model, a twelve-cylinder powerplant provides outstanding propulsion. The “W12” abbreviation alludes to the unusual configuration of the 6.3-liter FSI engine: four rows consisting of three cylinders each. Two rows in each case face each other in an offset configuration at a 15-degree angle, collectively forming a single broad bank. Both cylinder banks thus form a 72-degree V configuration.

    4.0 TFSI engine with cylinder on demand

    The new 4.0 TFSI, a powerful V8 with twin turbochargers, is equipped with “cylinder on demand” technology. When operating at part load, four of its cylinders are deactivated. This reduces fuel consumption by an average of five percent. To complement this system there are two further technologies: Active noise control (ANC) and active engine mounts. They ensure that the car’s occupants do not hear or sense any disturbing noise or vibration even if the engine is operating in the four-cylinder mode.

    FSI/TFSI principle

    FSI/TFSI principle

    At Audi, FSI stands for gasoline direct injection, a technology in which fuel is injected directly into the combustion chambers, rather than into the intake manifold in the traditional manner. More favorable in terms of thermodynamics, this method improves the efficiency of the engine. FSI engines achieve higher performance and better dynamics than conventional engines, with better efficiency. Whether they have four, five, six, eight, ten or twelve cylinders, all gasoline engines from Audi today employ the FSI principle.

    Exhaust turbocharger

    Downsizing has a long legacy at Audi – the first turbocharged gasoline engine, a five-cylinder unit, was produced as early as the late 1970s. Today the brand uses a turbocharger on all its four- and five-cylinder engines, both TDI and TFSI units, to increase performance and torque. Certain large V-engines employ two chargers according to the bi-turbo principle.

    Supercharger

    Alongside exhaust gas turbochargers, Audi also makes use of superchargers to boost its engines. A supercharger is used in the 3.0 TFSI. The high-efficiency mechanical charger is situated in the 90-degree V formed by the cylinder banks and is driven by the engine via a poly-V belt. The gas pathways downstream of the charger are very short, thus the torque develops quickly and easily. The full boost is available even at idle.

    Charge-air cooler

    As a turbocharger compresses the intake air, it heats up, reaching temperatures between 120 and 150 degrees Celsius (between 248 and 302 degrees Fahrenheit). Hot air has a lower density, however, and thus contains less oxygen for combustion. A charge-air cooler is therefore placed downstream of the turbocharger to cool the compressed air before it enters the combustion chamber.

    The engine ancillaries offer tremendous potential for efficiency. A new generation of oil pumps, which Audi employs in a number of models, are an important component. Smaller in terms of delivery rate, these volumetric-flow-controlled oil pumps operate only as required, and no longer need to circulate oil continuously.

  • High-tech: Audi uses most modern ways in engine production

    Internal friction

    Internal friction

    Combustion engines are subject to friction losses, in which a portion of the power disappears in the mechanical interaction of the engine components. The greatest losses occur in the crankshaft – at the pistons with their sealing rings, at the connecting rod bearings and at the main bearings of the crankshaft.

    Innovative thermal management

    The novel thermal management system, an innovation from Audi in many engines, lowers fuel consumption by up to 3 percent. Rather than being circulated, the coolant remains still during the warm-up phase so that the engine oil quickly reaches its operating temperature of between 80 and 120 degrees Celsius (between 176 and 248 degrees Fahrenheit). This significantly shortens the phase of greater frictional resistance due to viscous oil in the crankshaft drive and valve gear.
