The new Audi RS 6: The confidently superior sports sedan from quattro GmbH

426 kW (580 hp) and 650 Nm (479.42 lb-ft) of torque – with its twin-turbo V10 and quattro permanent all-wheel drive, the Audi RS 6 is a car without equal. Following on the heels of the RS 6 Avant, Audi now presents the sedan. It drives like a supercar thanks to its superior performance and thrilling dynamics, yet offers all of the everyday utility of a large business sedan.

The engine of the new Audi RS 6 is a high-tech work of art. The 4,991 cc V10 bundles a number of Audi’s race-winning technologies – FSI direct fuel injection, dry-sump lubrication and two turbochargers. With up to 1.6 bar of boost pressure, these provide smooth, powerful thrust and an incomparable power band: The peak torque of 650 Nm (479.42 lb-ft) is available from 1,500 to 6,250 rpm and thus nearly over the entire rev range. Peak power of 426 kW (580 hp) is generated between 6,250 rpm and the maximum figure of 6,700 rpm.

With a power-to-weight ratio of 3.4 kilograms per hp, the Audi RS 6 performs like a supercar. It catapults to 100 km/h (62.14 mph) in 4.5 seconds on its way to an electronically-limited top speed of 250 km/h (155.34 mph), which can be optionally raised to 280 km/h (173.98 mph). The V10 responds immediately and spontaneously to the throttle, and is very smooth while accelerating with a powerful roar.

The engine’s power flows through the six-speed tiptronic, one of a new, dynamic generation of Audi automatic transmissions. Its reaction time has been reduced to one tenth of a second, shift time has been halved compared to units used in other models and transmission ratios are short. The driver can also manually change gears either using the shift lever or the paddles on the steering wheel. The tiptronic transmission transfers the power to an extremely sporty, rear-weighted quattro drive train.

The technology bundled into the suspension of the Audi RS 6 guarantees an amazing performance experience. The front axle features four lightweight aluminum control arms per wheel, whose elastokinematics have been designed for particularly sporty performance. The characteristics of the speed-dependent servotronic power steering were retuned and the steering gear ratio is a direct 12.5:1. The rear suspension kinematics have also been modified.

The development engineers have also deployed an exclusive damping technology: Dynamic Ride Control DRC reduces pitch and roll using purely mechanical means. Hydraulic lines and valves connect diagonally opposed pairs of shock absorbers.

When cornering, the flow of fluid to the damper of the compressing outside front wheel increases, providing firmer support and reducing roll. When combined with the sports suspension plus, DRC offers a choice of three selectable damper settings – sport, dynamic and comfort – which can be activated via the MMI.

The electronic stabilization system ESP offers maximum driving fun with uncompromised safety. Its relatively high activation threshold encourages a dynamic driving style. It offers a Sport mode and can also be deactivated entirely.

The new Audi RS 6 rolls on 19-inch alloy wheels shod with 255/40 tires. Up front, six-piston fixed aluminum calipers – painted black and decorated with RS badges – clamp down on 390 millimeter brake disks. The rear brake disks measure 365 millimeters in diameter. The rear axle features single-piston floating brake calipers. The floating steel disks feature large cooling ducts and axial perforations for enhanced performance and less weight.

9.5J x 20-inch wheels are offered as an option. These allow the use of a ceramic brake system. The 420 (front) and 356 (rear) millimeter disks weigh a total of 12.2 kilograms (26.90 lb) less than the steel disks. The calipers – up front with eight pistons – are painted anthracite and labeled "Audi ceramic."

The body of the 4.93 meter (16.17 ft) RS 6 also sports a number of distinctive features that immediately identify it as a dynamic, top-of-the-line model. These include the single-frame grill, the air intakes, the headlights featuring xenon plus, adaptive light and RS 6-specific LED daytime running lights, the flared fenders and deep side skirts, the rear diffuser, the spoiler integrated into the trunk lid and the two large oval exhaust pipes.

Like all Audi RS models developed and built by quattro GmbH in cooperation with AUDI AG, the RS 6 is the embodiment of power, elegance, exclusivity and perfection. The interior is adorned with the finest of materials such as carbon fiber, aluminum, piano lacquer, leather and Alcantara in tried-and-tested Audi quality.

The deeply sculpted sports seats provide optimal support and firm hold. The power-adjustable seats are upholstered in Silk Nappa leather, with leather/Alcantara and Valcona leather available as options. Bucket seats with an even more sporty emphasis are also offered for both driver and front passenger.

Standard equipment includes the dual-zone deluxe automatic air conditioning plus, a parking assistant at front and rear, an RS leather multifunction sports steering wheel with flat-bottomed rim and a Bose surround sound system. A boost pressure indicator for the two turbochargers in the driver information system rounds out the instrumentation.

The options are also pure hi-tech: Audi lane assist helps to keep the car in its lane, adaptive cruise control maintains a constant distance to the car ahead and Audi side assist helps the driver change lane safely. The Audi Bluetooth car phone integrates perfectly with the driver’s cell phone to make even using the phone a luxurious experience. It is integrated into the standard MMI operating system, a new generation of which is making its debut in the Audi RS 6.

The Audi RS 6 will be launched on the market in mid-October. The starting price in Germany including VAT is 105,550 euros.
