The wide track and long wheelbase are key features of the balanced, sporty suspension tuning of the new Audi A5 Sportback*. The track measures1,587 millimeters (62.5 in) at the front and 1,568 millimeters (61.7 in) at the rear. The wheelbase is 2,824 millimeters (111.2 in).
Updated five-link suspension is used on the front axle. The axle principle enables optimal absorption of longitudinal and transverse forces. Its mounts are sportily rigid in a lateral direction and supple and soft longitudinally.A hydraulic mount reliably eliminates vibrations. It offers optimal comfort combined with a high degree of agility.
The newly developed electromechanical power steering helps to improve efficiency by trimming 3.5 kilograms (7.7 lb) off the weight of the previous model. It consumes little energy and has a direct, sporty ratio of 15.9:1. Power assistance is based on the vehicle’s speed. The steering provides highly precise feedback from the road and gives a spontaneous response.
The optional dynamic steering uses a superposition gear to vary its ratio by up to 100 percent, depending on the car’s speed and the mode selected in the Audi drive select dynamic handling system. It also supports and enhances stabilization of the car with lightning-fast steering movements.
At the rear of the new Audi A5 Sportback, a five-link axle replaces the trapezoidal-link axle of the previous model. Audi has used an intelligent mix of materials to reduce the weight of the axle components by an additional five kilograms (11.0 lb). Low unsprung masses combine with the new damper and elastomer bearing settings to produce a sporty driving experience and silky smooth travel.
Suspension with damper control
The variable suspension works with newly developed CDC dampers (CDC = continuous damping control). The pistons contain electromagnetically actuated valves that are very energy-efficient in their control. The central suspension control unit, the electronic suspension platform, processes all sensor signals within milliseconds and controls each damper individually. Together with the large spread of the damper valves, this provides a wide range between gentle rolling and firm body control, depending on the driving situation.
Audi drive select dynamic handling system
The Audi drive select dynamic handling system is a standard equipment feature and comprises the comfort, auto, dynamic and efficiency modes, allowing the driver to influence the vehicle character. In individual mode, the driver can also adapt individual systems such as the engine or steering to their personal preferences. In the basic configuration, Audi drive select accesses the engine characteristic and the steering assistance. Optional equipment features extend its network. These include the automatic transmission, the cruise control or adaptive cruise control (ACC), the dynamic steering, the sport differential, the quattro all-wheel drive system with ultra technology, the Matrix LED headlights, the ambient lighting and the automatic air conditioning. The suspension with damper control is also available as part of the Audi drive select dynamic handling system.
Wheels and tires
The base version of the new Audi A5 Sportback is factory-equipped with 17-inch forged lightweight wheels. The design and sport lines are equipped with 18-inch flow-forming cast aluminum wheels. Audi and quattro GmbH offer a wide range of optional versions. These wheels go up to 19 inches in size. All tires have been optimized for rolling resistance, which reduces CO2 emissions by an average of 2.8 grams per kilometer (4.5 g/mi).
A wide range of brakes are also used. The TFSI with 140 kW (190 hp) has 16-inch floating caliper brakes on the front axle. Models with other engines are stopped by particularly lightweight, 17-inch aluminum fixed caliper brakes. Compared with the previous model, the brakes are a combined five kilograms (11.0 lb) lighter. On the front axle, the internally ventilated discs are up to 338 mm (13.3 in) in diameter. The electromechanical parking brake is integrated into the rear axle and features new holding and starting functions.
