Audi | RS Q3 Once Again with Five-cylinder Turbo

Audi has chosen a turbocharged five-cylinder gasoline engine for the top-of-the-range RS version of its Q3 compact SUV. The engine, which has a compression ratio of 10 : 1 and a cylinder capacity of 2480 cm3, reaches its peak power of 294 kW between 5850 and 7000 rpm. The maximum torque of 480 Nm is available from 1950 to 5850 rpm. At less than 50 cm in length, the engine is extremely compact. It weighs in at 26 kg lighter than its predecessor. Its crankcase is made of aluminum, which results in a saving of 18 kg. The cylinder liners are plasma-coated and the crankshaft main bearings are 6 mm smaller in diameter. The crankshaft is hollow bored

and is therefore 1 kg lighter, while the aluminum pistons have integrated channels for oil cooling. The power flows via a seven-speed dual-clutch S tronic gearbox to the quattro permanent all-wheel drive system, which distributes it as needed between the axles via a multi-plate clutch.
