The 1.0 TFSI with a displacement of 999 cm3 provides 85 kW (115 hp) and delivers 200 Nm (147.5 lb-ft) of torque at 2,000 to 3,500 rpm. Its NEDC consumption rate is limited to 4.5 liters per 100 kilometers (52.3 US mpg) – a CO2 emission level of 104 grams per kilometer (167.4 g/mi) (manual transmission). The new entry-level gasoline engine is efficient at no cost to driving pleasure. It accelerates the A3 from 0 to 100 km/h (62.1 mph) in 9.7 seconds, and presses forcefully ahead up to a top speed of 206 km/h (128.0 mph).
The compact design of the three-cylinder engine and its aluminum crankcase make for a weight of only 88 kilograms (194.0 lb). The forged connecting rods and aluminum pistons are so finely balanced that the engine does not need a balancer shaft for quiet and smooth running. There are twelve valves at work in the cylinder head; their intake and exhaust camshafts can be adjusted by 50 and 40 degree crank angles, respectively. The valve train module in which they rotate is lightweight and rigid. Below the module lies the exhaust manifold integrated in the cylinder head – an important part of high-performance thermal management.
Just like the crankcase, the head also has its own cooling circuit. Throughout the crank drive the masses are low in magnitude, as is the friction loss. The common-rail system builds up to 250 bar of injection pressure – a best value among TFSI engines.
