The 2026 Audi RS3 is a petrol sedan with AWD and seating for 5. It belongs to the 8Y generation. The Sportback is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured Sportback version develops 407 hp and 500 Nm (369 lb-ft) of torque. Its listed 0-100 km/h time is 3.7 seconds, which is seriously quick. Top speed is listed at 300 km/h (186 mph). Its power output is about 40% above the peer average. Its 0-100 km/h time is about 38% quicker than the peer average. The figures establish its straight-line performance on paper, but they do not substitute for measured braking, handling or ride-quality tests.
Fuel economy and range
The listed fuel consumption is 9.1 L/100km. Fuel-tank capacity is 50.0 litres (13.2 US gallons). Recorded CO2 emissions are 208 g/km. Consumption, emissions and range can be measured under different regional procedures, so like-for-like comparisons should use the same market and test cycle.
Dimensions and practicality
Its exterior dimensions are 4,381 mm (172.5 in) in length, 1,851 mm (72.9 in) in width, and 1,431 mm (56.3 in) in height, while the wheelbase measures 2,636 mm (103.8 in). Cargo capacity is listed at 282 litres (10.0 cu ft), expanding to 1,104 litres (39.0 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 1,575 kg (3,472 lb). That cargo volume is about 35% below the peer average. The measurements are useful for comparison, although seat comfort, access and the shape of the load area still need to be judged in person.
In perspective
Compared with nearby petrol sedan models from the same period, the 2026 Audi RS3 is strongest on power and acceleration, while cargo capacity and price stand out as the principal numerical compromise. That conclusion is drawn from the recorded specifications rather than a road test. A final choice should also account for local pricing, equipment, comfort and a test drive.
