The Audi A5 models set standards for sporty dynamics, luxurious ride comfort and excellent driving safety. Most of the components of the five-link front suspension and the trapezoidal-link rear suspension are made of aluminum. The rear suspension bearings and the damper tuning have been updated for more precise handling and even greater comfort.
The ESP stabilization program with electronic limited slip differential is standard in all front-wheel drive versions of the Audi A5. ESP uses minimal braking interventions at the inside front wheel for even more agility during dynamic driving. The large brakes - with ventilated front and rear discs in many variants - offer excellent stopping power and are very easy to modulate.
17-inch wheels with 225/50 tires are standard. Options include wheels up to 20 inches and 265/30 tires as well as four new wheel designs.
Among the high-end features in the model series is Audi drive select. In the basic configuration, it adjusts the power steering boost, the accelerator characteristic, the shift points of the automatic transmission and the automatic air conditioning. Using a button in the cockpit, the driver can determine whether these components should work in "comfort," "auto," "dynamic" or "efficiency" mode. The latter helps to drive the Audi A5 particularly efficiently. If the car is equipped with a navigation system, there is also an "individual" mode that the driver can largely configure him or herself.
Audi drive select can be combined with additional modules, if desired. These are the sport suspension with damper control, the sport differential and dynamic steering, which steplessly varies the steering ratio by nearly 100 percent as a function of speed.
Another new standard feature in the Audi A5 model series is the electromechanical power steering. An electric motor generates the right amount of boost for the speed being driven. The electromechanical power steering features a direct ratio, reacts instantly and provides precise road feedback. It intervenes slightly to support the driver when braking on a surface with less grip on one side of the car.
The system reduces fuel consumption by up to 0.3 liters per 100 km and up to 7 g CO2/km (11.27 g/mile) because it consumes no energy at all while driving straight.
