Audi’s compact RS models are launched with the most powerful series-production five-cylinder in the world

The first compact notchback Audi with an RS badge has landed, in the form of the Audi RS 3 Sedan. Featuring the most powerful series-production five-cylinder engine in the world, the 400 bhp, 2.5-litre TFSI rockets the RS 3 Sedan and RS 3 Sportback to 100 km/h in only 4.1 seconds.

With an aluminium crankcase, the newly developed engine is 26 kilograms lighter than its predecessor, and produces an additional 33 bhp. Maximum torque of 480 Nm is available from as low as 1,700rpm.

Power is converted to motion thanks to an S-tronic seven-speed dual-clutch transmission, working together with quattro permanent all-wheel drive. Power is split between the axles, depending on how spirited the driving style is, with the electro-hydraulic multiplate clutch allocating more torque to the rear axle when necessary.

Through Audi's Drive Select dynamic handling system, drivers can choose to tweak not just the quattro management system, but also the steering, S-tronic, the engine management, the adjustable exhaust flaps, and even the (optional) RS sport suspension plus which offers adaptive damper control.

Inside, the driving experience is enhanced by an RS sport leather steering wheel with a flattened bottom section. Sport seats upholstered in black Nappa leather are standard equipment, whilst more contoured RS sport seats are available as an option.

To accentuate the car’s sporty character, the two main instrument dials are black with red needles and white scales, and the centrally positioned driver information system includes a boost pressure indicator, an oil thermometer and a lap timer.

Now available at the Audi Centre Singapore, the new Audi RS 3 Sedan is priced at $303,550 including COE. The Audi RS 3 Sportback, however, is not yet homologated for sale.
