The refined exterior design of the two RS 5 models is recognisable at first glance. The singleframe has become wider and flatter following the design of the RS 6 and RS 7. Implied air vents above the grille are reminiscent of the classic Audi Sport quattro from 1984. The wheel arches, which are 40 millimetres (1.6 in) wider, give the RS 5 an impressive appearance. The optional matrix LED headlights with Audi laser light feature darkened bezels, which clearly set the two RS models apart from the basic A5 model. The large, strongly contoured air inlets have been given a new, pentagonal cut.
The side sills and the diffuser insert at the rear end, which encloses the two large tailpipes of the exhaust system, have also been redesigned. The gloss black, matt aluminium, and carbon styling packages give the attachments at the front and rear ends and the side sills an even more individual look. The four rings and RS logos can be designed in black upon request. The colours Turbo blue and Tango red have been added to the colour palette. The Coupé is fitted with a carbon roof with a CFRP fibre structure which lowers the vehicle’s weight by just under four kilograms (8.8 lb).
The interior is dominated by horizontal lines and dark colours, the RS sport seats are covered with Alcantara and leather as standard, or fine Nappa leather as an option. Control elements, for example the steering wheel, are fitted with Alcantara covers with red or grey contrasting stitching.
The 10.1-inch MMI touch display, with a large, free-standing display is slightly inclined toward the driver. In the optional Audi virtual cockpit plus (12.3-inch display), the driver can select between multiple screens. One screen, the RS-specific performance design, displays the rotational speed scale as a kind of angle that includes a shift light display. When the driver uses the RS mode steering wheel button to select one of the two new individual RS modes, the RS-specific performance design opens up and displays the maximum g-acceleration values, for example. The optional head-up display also offers exclusive RS graphics.
Immense tractive power and a high output combined with efficiency: The 2.9 TFSI twin-turbo V6, the heart of the RS 5 models outputs an unchanged 331 kW (450 PS) and already delivers a whopping 600 Nm (442.5 lb-ft) of torque as from a speed of 1,900 rpm. Both RS 5 models accelerate from zero to 100 km/h (62.1 mph) in 3.9 seconds and reach a top speed of up to 280 km/h (174.0 mph).
A quick-shifting eight-speed tiptronic directs the power of the engine to the quattro permanent all-wheel drive. The driver can control the gear change via the new larger aluminium shift paddles. The quattro drivetrain provides the two RS models with the crucial amount of additional traction, dynamism, and stability, regardless of the weather. The optional sport differential at the rear axle, makes the handling even sportier and distributes the torque actively between the wheels.
The two RS 5 models are fitted as standard with a taut RS sport suspension. In addition to the familiar comfort, auto, and dynamic modes, the Audi drive select dynamic handling system also now offers the two new modes, RS1 and RS2. Once the driver has set the two modes to suit their personal preferences, they can be enabled directly via the “RS MODE” button on the steering wheel without having to operate the MMI touch response. The system accesses important technical elements like the engine, transmission, damping, steering, dynamic steering, sport differential, and engine sound.
The updated RS 5 models come with 19-inch wheels with new 20-inch wheels available upon request in three variants, one of which is painted completely in gloss black and another in matt bronze. In the standard brake system, steel disks are gripped by calipers painted in black or red. As an alternative, Audi offers carbon fibre ceramic brake disks for the front axle; their calipers are painted in grey, red, or blue.
