Audi's RS5 is coming to the US with 450HP and a top speed of 174 MPH. Even with a fresh new design, we still think the Audi RS5 won't do well, it's price tag is super high and performance is not that astounding. Â BMW's M3 coupe can outperform the Audi in every category for less money.
The Audi RS 5 CoupÃ© uses a high-revving, normally aspirated V8 displacing 4,163 cc. This engine is closely related to the V10 that powers the R8 high-performance sports car. The 4.2 FSI delivers 331 kW (450 hp) at 8,250 rpm, with the peak torque of 430 Nm (317.15 lb-ft) available between 4,000 and 6,000 rpm. The engine has a specific output of 108.1 hp per liter of displacement. The potent response, the eager revving and the rich, melodious sound mark the V8 as a thoroughbred racing engine.
Hand-built at the plant in GyÃ¶r, Hungary, the 4.2 FSI launches the CoupÃ© from zero to 100 km/h (62.14 mph) in 4.6 seconds. Audi will increase the electronically governed top speed from 250 to 280 km/h (155.34 to 173.98 mph) upon request. Thanks to the combination of technologies from the Audi modular efficiency platform, which also includes a recuperation system, the high-tech V8 consumes significantly less fuel on average than its direct competitors.
With its high efficiency and its long top gear, the standard seven-speed S tronic also contributes to the good fuel economy. Drivers can let the lightning-fast dual-clutch transmission shift automatically or change gears themselves using the selector lever or with paddles on the steering wheel. The integrated launch control program provides for rocket-like starts by managing the engagement of the clutch at mid-level revs.
High end: quattro with crown-gear differential
Like all RS models, the RS 5 CoupÃ© also applies its power to the road with quattro permanent all-wheel drive. The crown-gear center differential at its heart is compact and lightweight. It can vary the distribution of torque between the front and rear axles lightning-fast and over a wide range, with up to 70 percent flowing to the front or as much as 85 percent to the rear, as necessary. The default 40:60 ratio of the rear-biased configuration ensures sporty handling.
The crown-gear center differential works together with the torque vectoring system, which acts on all four wheels. If the load on the inside wheel is reduced too much while the car is being driven dynamically, that wheel is braked slightly before it can begin to slip. Audi offers the sport differential as a complementary option that actively distributes the power between the rear wheels via two superposition stages.
Precise and stable: the chassis
The chassis of the RS 5 CoupÃ© unites fast and precise turn-in, high cornering speeds and supreme stability. Most of the components of the five-link front suspension and the self-tracking trapezoidal-link rear suspension are made of aluminum. The new speed-dependent power steering is an electromechanical system with a direct steering ratio for highly precise road feel. It supports the driver with slight steering corrections when braking on surfaces with different amounts of grip. Because the power steering draws no energy when driving straight ahead, it helps to enhance efficiency.
The taut setup lowers the body by 20 millimeters (0.79 in) compared with the Audi A5. Newly designed, 19-inch forged aluminum wheels with 265/35-series tires are standard; 20-inch wheels with 275/30-series tires are available as an option for the high-performance coupe.
The brake system of the RS CoupÃ© features large, internally ventilated wave brake discs, with the front discs measuring 365 millimeters (14.37 in) in diameter. The steel friction rings with their wave-like outer contour are perforated and connected to the aluminum brake caps via pins. This direct structure reduces tensions, quickly dissipates the heat and prevents the transmission of temperature peaks. Moreover, the redesigned shape of the friction rings results in three kilograms (6.61 lb) of weight being saved in total, thus improving the balance of unsprung masses.
The calipers are painted high-gloss black; the front calipers have eight pistons each. The RS 5 can be optionally equipped with carbon fiber-ceramic discs up front. The electronic stabilization program (ESP) integrates a sport mode and can be switched off entirely.
Upon request, Audi equips the RS 5 with a particularly dynamic damping technology â€“ the sport suspension plus with DRC dynamic ride control. The diagonally opposed pairs of shock absorbers are linked by hydraulic lines and a central valve. During fast cornering, the system intensifies the stabilization of the front outside wheel. The sport suspension plus features a three-stage, variable damping characteristic.
The Audi drive select driving dynamics system comes standard with the RS 5 CoupÃ©. This system allows the driver to select between three modes â€“ comfort, auto and dynamic â€“ for the characteristics of the steering, the seven-speed S tronic and the accelerator. And if the car is equipped with an Audi MMI navigation system, there is also a fourth mode â€“ individual â€“ which can be configured by the driver. Audi drive select can also modulate the sound of the exhaust system, double-clutching when downshifting in dynamic mode.
Dynamic steering is another module available for Audi drive select beside the sport differential and the damping characteristic in the sport suspension plus. It uses a superposition gear to vary the steering ratio by nearly 100 percent as a function of speed and countersteers slightly at the cornering limit.
Unmistakable: The design
The RS 5 CoupÃ© has an athletic road stance, and its classically elegant two-door lines dazzle with clear-cut accents. The new single-frame grille with beveled upper corners features a high-gloss, anthracite gray honeycomb structure and a matt aluminum-look frame. The standard xenon plus headlights are framed by narrow strips of LED daytime running lights. The air flows through large openings embedded in a distinctive bumper featuring a splitter edge like on a racing car. Sharper edges make the engine hood appear more three-dimensional so that the RS 5 looks even lower and wider when viewed from the front.
The flared aluminum front fenders and the rear side elements with the sharp horizontal upper edges are reminiscent of two classic Audi models from the 1980s â€“ the all-wheel drive pioneer Audi quattro and the Sport quattro. The side sills sport chiseled caps; the trim strips and the side mirror housings have a matt aluminum-look finish.
The tail end is dominated by the two oval exhaust pipes of the dual exhaust system, which are integrated into the redesigned bumper. Audi also offers a sport exhaust system with a more voluminous sound and black exhaust tip bezels. The LED rear lights are also new and feature continuous light strips. The large diffuser extends far upward, and the spoiler in the rear hatch extends automatically at 120 km/h (74.56 mph).
The extensively clad underbody integrates air vents for the seven-speed S tronic and the front brakes. Thanks to its advanced aerodynamics, the RS 5 CoupÃ© generates downforce at high speed to further enhance stability.
The dynamic looks alter the dimensions slightly. The RS 5 CoupÃ© is 23 millimeters (0.91 in) longer and six millimeters (0.24 in) wider than the A5 CoupÃ©, but six millimeters (0.24 in) lower. Eight exterior colors are available, from solid, metallic and pearl effect finishes to a specially pigmented crystal effect paint.
