Six-speed manual transmission, seven-speed S tronic and eight-speed tiptronic, in combination with front and quattro all-wheel drive: In the new Audi A5 Sportback*, each engine version comes with tailored power transmission technology.
New efficiency-optimized six-speed manual transmissions with injection lubrication are used. The housings are made extensively from ultra-lightweight magnesium.
The new seven-speed S tronic is available with all engines except the top TDI and the S5*. The dual-clutch transmission is standard with the 3.0 TDI with 160 kW (218 hp). The S tronic, which supersedes the continuously variable multitronic, offers impressively high efficiency. The most important improvements are further reductions in friction, the low weight, a highly efficient oil supply and dual-mass flywheel with a centrifugal force pendulum, which allows for very low engine speeds while driving.
An eight-speed tiptronic features in the 3.0 TDI with 210 kW (286 hp) and the S5. Audi has completely reengineered the smooth, rapid and spontaneously shifting torque-converter transmission. Thanks to the high number of gears, the engine is kept running almost constantly at the ideal load point. An rpm-adaptive torsion damper balances out undesired engine vibrations and enables efficient driving at extra-low engine speeds.
The new Audi A5 features front-wheel drive as standard. quattro all-wheel drive with wheel-selective torque control is available as an option. It is standard for the 3.0 TDI with 210 kW (286 hp).
For the future: quattro with ultra technology
The new quattro with ultra technology is available for the TFSI and TDI four-cylinder engines with manual transmission. The efficiency-optimized all-wheel drive system does not perceptibly differ from permanent systems in terms of traction and driving dynamics. This is all thanks to the combination of the newly developed all-wheel drive components with a sophisticated operating strategy and a torque split perfectly matched to the car. The all-wheel drive system’s intelligent control works predictively, always looking ahead by means of a comprehensive array of sensors and the continuous analysis of the driving dynamics, road condition and driver behavior data collected.
During operation at low loads without the risk of wheel slip, the new quattro drive exploits all the advantages of front-wheel drive. But the all-wheel drive system is always ready when needed. This system significantly reduces the potential difference in fuel consumption between front-wheel drive and permanent all-wheel drive systems.
Heart of the matter: self-locking center differential
All engine variants of the Audi A5 Sportback with S tronic or tiptronic continue to be equipped with quattro permanent all-wheel drive. It is an extremely reliable mechanical system. Designed as a planetary gear, the self-locking center differential funnels 60 percent of engine torque to the rear axle and 40 percent to the front during normal driving. When it redistributes the power, up to 70 percent can go to the front and up to 85 percent to the rear. It enables a clearly defined distribution of drive torque and precise interplay with the control systems.
As an option for the top TDI and the S5, Audi complements quattro all-wheel drive with another dynamic technology component – the sport differential. It uses two superposition gears to distribute torque between the rear wheels. The latest generation of the differential is roughly one kilogram (2.2 lb) lighter. During fast driving, the sport differential literally pushes the car into the curve, nipping understeer in the bud. When turning into or accelerating in a curve, most of the torque is directed to the outside wheel.
The central suspension control unit (electronic suspension platform) again takes care of constantly calculating the ideal distribution in terms of driving dynamics.
