Audi UK has announced the RS5 facelift order books open this week with a starting price of £58,725 OTR.

First revealed at the Frankfurt Motor Show last September, the RS5 features a hand built 4.2-liter V8 that has an output of 444 hp (331 kW / 450 PS) and peak torque of 317 lb-ft (430 Nm) via a Seven-speed S-tronic transmission going down to the quattro permanent all-wheel-drive system. A sport differential is available as an option.

The RS5 Coupe does the 0 to 100 km/h sprint in 4.5 seconds and has an electronically-limited top speed of 250 km/h (155 mph). However, for an additional fee, Audi can de-restrict this limitation for a new top speed of 174 mph (280 km/h).

Stylistically, the new RS5 receives a revised single frame grille design, sharper and more pronounced hood contours, new 'solid band' wraparound LED daytime running lights and LED rear lights, new look front and rear bumpers and a new '10-spoke' design for the 19-inch alloy wheels.

On the inside there is a new flat-bottomed RS three-spoke steering wheel and detail improvements to the air conditioning, Multi Media Interface, mirror adjustment and electric window switchgear, the gear lever and the instrument stalks. New look optional inlays are also now available.

The RS5 comes quite loaded with standard features such as a Bluetooth mobile phone integration, cruise control, DVD-based satellite navigation and Audi Music Interface iPod connection, but there are a few optional extras available.

Audi offers a new optional Sport Package at £2,250 which includes Dynamic Ride Control, sports exhaust, dynamic steering and 20-inch rotor-design titanium-look alloy wheels. The cruise control system can also now be upgraded at extra cost (not specified) to the adaptive system with braking guard, which uses radar sensors to control distance from traffic in front of the car between 19mph and 155mph, and can also initiate partial braking or full deceleration if its sensors detect an impending collision.

Audi RS5 deliveries begin in April.
