RS3

The highest specification RS 3 model is fitted with a 2.5-litre 5-cylinder producing 400 PS (294 kW; 395 hp) and 500 N⋅m (369 lb⋅ft), and has 0-60 mph (97 km/h) acceleration time of 3.8 seconds. It gets a seven-speed dual-clutch automatic S-Tronic gearbox. It also gets the new MMI infotainment system, with a 10.25 or 12.3-inch digital instrument cluster, and a secondary screen of 10.1-inches. With the RS Dynamic package the speed limiter is removed, allowing the RS3 to reach a top speed of 290 km/h (180 mph).^[74] The US-market RS3 produces marginally more power than the European RS3, at a claimed 401 hp (299 kW; 407 PS).^[75] This is partially due to the lack of a petrol particulate filter for US model cars, as it is not required to meet emissions standards. The US-market RS3 instead receives a secondary catalytic converter.

In October 2022, the RS3 Performance Edition was introduced for European buyers. The boost was increased from 1.5 to 1.6 bar (21.8 to 23.2 psi), bringing power up to 407 PS (299 kW; 401 hp) and thus matching the peak power of the federalized version. Torque remained as before but across a slightly wider range.^[74] The (unlimited) top speed reaches 300 km/h (186 mph), a first for an A3 based model. Production is limited to 300 units.^[74]
