The fast, spontaneously and sportily shifting eight-speed tiptronic with optimized shift times is standard on the new RS 5 Coupé (combined fuel consumption in l/100 km: 8.7; combined CO2 emissions in g/km: 197). The layout of its gear sets and shifting elements results in low drag torques and thereby to a high efficiency level. Its large number of gears very frequently makes it possible to operate the engine close to its ideal load point. The lower gears have short, sporty ratios, while the upper gears are long in order to reduce revs and fuel consumption.
The driver can select between the D and S modes and can use the special RS shift paddles on the steering wheel for manual gear changes. All commands are transmitted to the transmission electrically – by wire. The dynamic starting function controls starts with optimum traction. Using it, the RS 5 Coupé can unfold its full acceleration potential. Prerequisite: the ESC sport mode must be active and the selector lever must be in the S position.
Dynamic power distribution: the quattro drive
The quattro permanent all-wheel drive is a unique selling point in the segment. With its asymmetrically dynamic setup, it makes a great contribution to the sporty yet stable handling of the new RS 5 Coupé. In regular driving, the system delivers slightly more power to the rear axle. Its purely mechanical center differential directs 60 percent of the torque to the rear axle and 40 percent to the front. If slip occurs at one axle, most of the power is rapidly redirected to the other axle – up to 85 percent to the front or up to 70 percent to the rear axle. These high locking figures enable a clearly defined torque distribution and precise interplay with control systems.
The optional Sport differential with RS-specific tuning ensures an even more dynamic response when cornering and accelerating. It distributes the torque actively and in a targeted manner between the rear wheels. In the latest generation, the differential now weighs around one kilogram (2.2 lb) less.
The wheel-selective torque control rounds out the work of the quattro drive system. When cornering fast, it applies precisely calculated brake interventions at the wheels on the inside of the curve before they begin to spin. The difference between propulsive forces at the wheels makes the car turn into the curve ever so slightly – agility, precision and stability are all further improved.
Tuned specifically to the RS: stabilization control with three modes
The developers have applied RS-specific tuning to the Electronic Stabilization Control (ESC) and the anti-slip control. In addition to the normal mode, there is also a sport mode in which the ESC intervenes later. This mode provides additional driving pleasure, and also enables controlled drifting on low-friction road surfaces. If the driver pushes the button for longer than three seconds, the ESC switches off completely to allow particularly sporty handling.
