AUDI Sport has updated its RS line up with the brand's latest electrified powertrain technologies in the new RS 5 saloon and Avant, its first ever plug-in hybrid RS models.

Available to order in the UK now and priced from £89,400 and £91,300 respectively, the new top-tier models combine a 2.9-litre, 510ps twin-turbo V6 and a 130kW electric motor for breathtaking performance and the potential for an electric-only driving range of up to 52 miles.

The first UK deliveries of the new RS 5 are scheduled for the summer.

With their characteristic flared wheel arches, striking detailing and sizeable wheels the latest RS 5 models make no secret of their tremendous performance potential.

At the front, the hallmark RS honeycomb Singleframe grille is linked by a dark mask to pronounced Air Curtains that streamline air flow, while vents in the wings add drama to the profile in conjunction with blisters in the shoulder line that pay homage to the iconic Audi Ur quattro.

Below the tailgate with its integrated spoiler, the trademark big-bore RS oval tailpipes are centrally positioned within a diffuser featuring aerodynamically optimised vertical fins and a motorsport-inspired red reflector.

"As the first highâperformance plugâin hybrid, the RS 5 marks the beginning of a new era for the Audi Sport brand," said Audi UK director, José Miguel Aparicio.

"For decades, Vorsprung durch Technik has been demonstrated through the continued innovation of our RS models, driven by a singular focus: delivering the ultimate performance car for our customers. With the introduction of plugâin hybrid technology to the RS lineâup, Audi Sport is taking usability, performance and excitement to an entirely new level."

In the UK, the RS 5 Saloon and Avant models will be available with a choice of three specification options: RS 5, RS 5 Carbon Black and RS 5 performance Vorsprung.

At the entry point to the range, the RS 5 models ride on 20-inch six-twin-spoke alloy wheels finished in dark Galvano silver and feature a black styling package taking in elements including the spoiler, window trim, door mirror surrounds, door handle inserts, RS badges and Audi rings.

As part of the upgrade to Carbon Black specification, the RS 5 gains larger 21-inch alloy wheels in the twin-spoke design in Neodymium grey matte, along with a high gloss carbon finish for the rear spoiler, mirror housings, front air intake blades and side skirts. In the RS 5 Saloon Carbon Black the lipped rear diffuser surround is also trimmed in high gloss carbon.

At the very top of the range, the RS 5 performance Vorsprung models have exclusive RS performance bumpers incorporating further enlarged air intakes at the front and an even more distinctively styled rear diffuser, which houses matte black tailpipes. These not only differ visually from the dark chrome-plated pipes fitted elsewhere in the range but also produce an even more evocative RS sound as part of the top model's RS sport exhaust system upgrade.

The RS 5 performance Vorsprung models are unique in the range in featuring an upgrade from LED to second-generation Digital OLED taillights offering selectable digital light signatures, including a chequered flag signature that is unique to the RS 5. They also incorporate an innovative communication light that can display integrated warning symbols to alert other road users to hazards.

Inside, the RS 5's cabin's sporting focal points are the exceptionally supportive sport seats plus with their massage and ventilation functions and honeycomb quilting, and the heated RS sport steering wheel with its flat top and bottom, motorsport-inspired 12 o'clock marker and integrated RS drive mode satellite controls. Interior accents with a Vanadium-effect finish and inlays in a black-painted aluminium design.

Whether on road or track, the power and torque output of 639ps and 825Nm delivered jointly by the 2.9-litre V6 TFSI and 130kW motor enables the RS 5 Saloon and Avant models to accelerate from 0-62mph in 3.6 seconds. The driver can activate a boost function to enjoy maximum acceleration in ten-second phases, optimising overtaking capability. Where conditions allow, a top speed of 155mph is achievable in RS 5 and RS 5 Carbon Black versions, while RS 5 performance Vorsprung models - priced from £107,485 - feature an elevated 177mph top speed.

During braking and coasting, intelligent recuperation technology harvests energy for the upgraded battery, and when plugged in, the RS 5 can charge at up to 11kW, meaning the battery can be restored from to 100 per cent in 2.5 hours.
