The Audi A5 family sets new standards for sportiness and efficiency. All engines feature forced induction and direct injection for tremendous pulling power. Even the entry-level engine produces 320 Nm (236.02 lb-ft) of torque. The start-stop system and the recuperation system are standard with all engines - no other manufacturer takes such a rigorous approach. The lineup comprises three gasoline engines and four TDI units. CO2 emissions have been reduced by as much as 22 percent.

The completely redesigned 1.8 TFSI showcases the full extent of Audi's expertise. Groundbreaking innovations can be found in the control of the valves and their lift, the thermal management concept, the injection system, the turbocharger and the integration of the exhaust manifold. In the Audi A5 Coupé, the high-end four-cylinder unit consumes on average just 5.7 liters of fuel per 100 km (41.27 US mpg). This best-in-class value corresponds to 134 grams CO2 per km (215.65 g/mile) and is 21 percent lower than before. With 125 kW (170 hp), the 1.8 TFSI accelerates the A5 powerfully.

The output of the 2.0 TFSI remains unchanged at 155 kW (211 hp). New to the Audi A5 lineup is the 3.0 TFSI, a supercharged V6 producing 200 kW (272 hp).

The diesel engines are also impressively efficient, and the four-cylinder units feature modifications in numerous areas. Equipped with the 130 kW (177 hp) 2.0 TDI and a manual transmission, the Audi A5 Coupé consumes on average just 4.7 liters of fuel per 100 km (50.05 US mpg) - a CO2 equivalent of 122 g per km (196.34 g/mile) and a milestone in the coupe segment.

Three V6 diesel units round out the lineup on the top end. The 3.0 TDI with 150 kW (204 hp) is the most fuel-efficient six-cylinder unit in its class worldwide. In the Audi A5 Coupé with multitronic, it consumes on average 4.9 liters (48 US mpg) of fuel and emits just 129 grams CO2 per km (207.61 g/mile). The second variant of the 3.0 TDI produces 180 kW (245 hp). Arriving somewhat later is a particularly low-emissions clean diesel model that will make the Audi A5 the first coupe on the market to meet the Euro 6 diesel standard.
