As sleek as high-performance coupes are, they're not exactly the most practical proposition. The folks at Audi found a solution to that by transforming the RS5 coupe into a five-door Sportback. With that, future RS5 owners can enjoy the performance of the car with much easier access to the back seats, should the need to carry more people arise.

Despite the extra doors, the Audi RS5 Sportback retains the aggressive front fascia treatment from its two-door sibling. For starters, the hood is buldged more compared to non-sporting A5 Sportbacks and the honeycomb grill treatment is exclusive to this model. Also, the lower part of the grill spells out Quattro, a unique touch to this high-performance model. Audi also did work on the rest of the body.

To accommodate the special suspension, the wheelarches have been flared and give it a wider stance. Chrome pieces have been replaced by gloss black trimmings while the tailgate comes with a lip spoiler as standard. The lower part of the bumper meanwhile houses two large oval tailpipes along with integrated diffusers near the exhausts. Overall, the RS5 Sportback sits lower and wider than the standard models, says Audi.

Inside, the design is largely carried over from the RS5 coupe save for special door trimmings for the rear. The center console is tilted towards the driver for an easier reach and, this being an RS model, it comes with a thicker-rimmed, flat-bottom steering wheel. Deeper bucket seats with unique patterns mark this as the most potent A5 customers can get. Also unique is a different configuration of Audi's Virtual Cockpit, displaying more information relevant to the vehicle's performance. Like the coupe, the RS5 Sportback can be specified with carbon-fiber trimmings.

The Audi RS5 Sportback gets the same engine as the two-door coupe. The Porsche co-developed 2.9-liter, twin-turbocharged V6 produces 450 PS and 600 Nm of torque. Quattro all-wheel drive is standard with more power being sent to the rear wheels. Transmission is an eight-speed automatic which helps propel it from 0 to 100 km/h in a claimed 3.9 seconds. Audi claims a top speed of 280 km/h with the speed limiter removed.
