Audi has revealed the updated RS3 Sportback. In fact, it will be a bit unfair to call it just an update, as the power output from the 2.5-litre five-cylinder engine has been bumped up by a good 33 horsepower to 400 horsepower (395bhp) now, while elsewhere it sees a host of design and connectivity upgrades.

The engine, which Audi says is the world’s most powerful production five-cylinder is 26kg lighter thanks to its aluminium crankcase, and apart from the increased power, also churns out a maximum torque of 480Nm, which is available from just 1,700rpm all the way to 5,850rpm. Mated to a seven-speed dual-clutch transmission, it helps the RS3 Sportback from 0-100kph in just 4.1 seconds and to a limited top speed of 155mph (250kph). If you spec it with the optional dynamic package plus, the top speed will be derestricted to 174kph (280kph).

“The Audi RS3 Sportback offers our customers an attractive introduction to the RS world,” says Stephan Winkelmann, CEO of Audi Sport. “Since 2011 the sporty compact model has proved itself extremely successful on the market. And with the new five-cylinder engine, the Audi RS3 Sportback is at the head of its class and continuing that strong track record.”

It obviously comes equipped with Audi’s Quattro all-wheel drive system, and the Audi drive select system, which alters the responses from the steering and transmission while also allowing the driver to control engine management, adjustable exhaust flaps and the optional RS sport suspension with adaptive damper control. These are complemented by the Electronic Stabilisation Control (ESC) with wheel-selective torque control and the sport mode specially tuned for the RS.

The RS3 Sportback will have its official debut at the Geneva motor show next month.
