Efficiency is standard on all Audi, Audi RS5 is no exception. The ultra-powerful eight-cylinder engine average 10.8 liters of fuel per 100 km (21.78 miles mpg U.S.) – far less than its main competitors. This impressive number is partly due to the technologies of modular platform Audi efficiency. The entire engine and transmission system have been optimized to minimize friction, the oil pump operates on demand, and an energy recovery system saves energy during coasting and braking.
The vigorous strength, the spontaneous responsiveness, the joyful high-revving, and the throaty, sonorous music: this V8 produced by hand at Audi stunningly combines the essence of power and emotion. The 4.2 FSI propels the coupé's 1,725 kilograms (3,802.97 pounds) in 4.6 seconds from 0 to 100 km/h (0 to 62.14 mph) to an electronically governed top speed of 250 km/h (155.34 mph). Audi can increase that to 280 km/h (173.98 mph) upon request.
Efficiency is standard in every Audi; the Audi RS5 is no exception. The ultra-powerful eight-cylinder engine averages 10.8 liters of fuel per 100 kilometers (21.78 miles US mpg) - far less than its main competitors. This impressive figure is due in part to the technologies from the Audi modular efficiency platform. The engine and the entire drivetrain have been optimized to minimize friction, the oil pump operates on demand, and an energy-recovery system conserves energy during coasting and braking.
The seven-speed S tronic, which was specially reinforced to accommodate the high-revving V8, can operate in fully automatic mode - or the driver can shift via the innovative selector lever or shift paddles on the steering wheel. By means of the standard Audi drive select, the driver can switch in automatic mode among three different options: auto, comfort, and dynamic. In the launch control program, the seven-speed S tronic ensures flawless acceleration from a standstill - at full power and with minimal tire slip.
Like all RS models, the Audi RS5 also applies its power to the road with quattro permanent all-wheel drive. As for the center differential, which regulates power distribution between the front and rear axles, Audi - the leading all-wheel-drive brand - unveils the next generation: a crown-gear differential.
The self-locking crown-gear center differential is compact and lightweight - and attains a high efficiency ratio.
Thanks to its package of plates, the differential can widely vary the distribution of torque between the front and rear axles. If necessary, up to 70 percent can flow to the front or as much as 85 percent toward the tail end. The 40:60 ratio of the standard rear-biased configuration ensures sporty handling.
As a perfect complement to the new quattro drivetrain, Audi can optionally position the sport differential at the rear axle. It actively distributes torque between the rear wheels in order to further boost stability and grip at the vehicle's limits of handling. The electronic management of the Audi RS5 sport differential was designed to be uncompromisingly dynamic.
With regard to the springs, shock absorbers, elastokinematics, and the anti-roll bars, the Audi RS5 chassis exhibits a sporty configuration and renders the body 20 millimeters (0.79 inches) lower than that of the Audi A5 . The 19-inch alloy wheels fitted with 265/35 tires are standard. They are executed in an exclusive 5-arm structure design. The Audi RS5 optionally comes with 20-inch wheels and 275/30 tires. Winter wheels featuring the same dimensions are available; the 19-inch wheel is suitable for snow chains.
The brake system employs powerful and internally ventilated discs, which measure 365 millimeters (14.37 inches) in diameter at the front axle. In order to maximize the dissipation of heat, the steel friction rings are perforated and connected by pins to the aluminum brake discs. The high-gloss black brake calipers bearing RS logos are likewise made of aluminum; the front calipers are fitted with eight pistons each. Audi can optionally fit the front axle with ceramic carbon-fiber brake discs measuring 380 millimeters (14.96 inches) in diameter. They are extremely lightweight, strong, and durable. The electronic stabilization program (ESP) integrates a sport mode and can be switched off entirely.
The speed-dependent servotronic steering in the Audi RS5 is especially taut. The standard Audi drive select (a vehicle-dynamics control system) allows the driver to switch among three modes of operation - comfort, auto, and dynamic - to adjust steering, the seven-speed S tronic, the sport differential, the engine, and the exhaust system. And if the car is equipped with the MMI navigation system, a fourth mode allows the driver to customize their own profile.
As regards the engine, Audi drive select controls the exhaust system's two throttle valves and the sound flaps; when they open, the rich sound becomes even more resonant. Along with the sport differential, dynamic steering is another optional component of Audi drive select. Dynamic steering adjusts the steering ratio to a vehicle's speed - directly for maneuvering at low speeds and indirectly for traveling at highway speeds. At the vehicle's cornering limits, it automatically ensures smooth handling via minor corrective actions.
The Audi RS5 exudes an athletic and powerful identity; its classically beautiful coupé styling dazzles with new and clear-cut accents. Its single-frame grille bears a shiny charcoal-gray rhombus-pattern grid. Xenon plus headlights boasting a sweeping strip of LED daytime running lights are standard. The oversized air inlets for the engine, front brakes, and the radiators are bordered by striking contours. The newly designed bumper tapers downward into a splitter.
The tail end is dominated by two oval exhaust pipes integrated within the bumper. A large diffuser protrudes prominently upward. The spoiler in the tailgate automatically extends at a speed of 120 km/h (74.56 mph) and retracts at 80 km/h (49.71 mph).
The extensively clad underbody of the Audi RS5 integrates air vents for the seven-speed S tronic and the front brakes. At highway speeds, the aerodynamic characteristics of the Audi RS5 generate downforce to further enhance stability.
The vehicle's dynamically elegant styling extends to the interior. Sports seats with pronounced side sections and integrated head restraints are standard. They are electrically adjustable and feature a leather/Alcantara combination. Alternatives include bucket seats with more prominent contours and folding backrests or ventilated and luxuriously upholstered climate-controlled comfort seats.
The steering wheel has a substantial rim and is covered with perforated leather. The instruments have black gauges and white lettering with distinctive scaling. When the ignition is switched on, the red needles briefly rise high and then drop back down. The driver information system integrates a lap timer for recording circuit times and an oil-temperature gauge. Just like the optional MMI navigation systems' monitor, it displays an RS greeting upon ignition.
