    Audi Q5 – quattro with ultra-technology

    With the exception of the 3.0 TDI, all Q5 versions have the completely newly developed quattro with ultra technology. It offers maximum efficiency and does not perceptibly differ from permanent systems in terms of traction and driving dynamics.

    The quattro permanent all-wheel drive system ensures optimal traction and handling under any road conditions. It comes standard with the 2.0 TFSI and the 2.0 TDI with an output of 140 kW (190 hp). It is optionally available for the 2.0 TDI with an output of 110 kW (150 hp).

    With quattro permanent all-wheel drive, Audi has extended its lead over a period of more than three decades. Now it’s time for the next big step: quattro in combination with ultra technology.

    The development goal of quattro with ultra technology is an all-wheel drive system optimized for efficiency with no discernible differences to permanent systems with respect to traction and driving dynamics. The system should set benchmarks in its class for fuel consumption and CO2 emissions, particularly under everyday conditions. With correspondingly equipped test vehicles, Audi developers used on average 0.3 liters/100 kilometers less fuel than with conventional all-wheel drive. The tests were conducted on a route throughout the Ingolstadt area and in normal traffic.

    The new quattro drive

    The new quattro drive

    In the powertrain, the lightning-quick shifts of the seven-speed S tronic dualclutch transmission, an optimized mechanical differential lock and a new electrohydraulically activated multi-plate clutch work together. The actively cooled allwheel drive system can distribute torque freely between the axles. The intelligent dynamic control system for the quattro drive is incorporated into the Audi drive select dynamic handling system that offers four basic modes. 

    In each mode, the new high-performance sports car expresses a different character – from relaxed freeway cruiser to race car on the circuit track. In the top R8 V10 plus model, a performance leather steering wheel is standard equipment. In its performance mode, it offers three additional modes: dry, wet and snow. They make handling even more precise and sharper, tuned to the friction coefficient of the specific road surface. The new technology is also available on the R8 V10, including the steering wheel that is used to select the special modes.

    Electronically controlled multi-plate clutch

    Electronically controlled multi-plate clutch

    Like all Audi S models the Audi S1 and the S1 Sportback (7.0 / 7.1 liters of fuel per 100 kilometers [33.60 / 33.13 US mpg]; 162 / 166 grams of CO2 per kilometer [260.71 / 267.15 g/mile]) come with permanent all-wheel drive – another USP in this segment. Weight distribution constraints mean the hydraulic multi-plate clutch is mounted on the rear axle (axle load distribution: front 60 percent, rear 40 percent). Depending on the driving situation, the electronically controlled clutch distributes the drive torque between the axles. If one of the axles starts to slip, the torque is instantly redirected to the other axle. The management of the multi-plate clutch is decidedly dynamic. It allows controlled drifts on a road surface with a low coefficient of friction in sport mode or with deactivated ESC.

  • Bevel gear center differential in the Ur-quattro

    The first Audi quattro, which debuted in spring 1980, was a technical sensation. Its permanent all-wheel drive was lightweight, compact and fast-running, thus making it suitable for high speeds. The elegant quattro principle did not need the heavy, separate transfer case and weighty auxiliary shaft to the front axle that were the standard at the time. It was the first volume-built permanent all-wheel drive system suitable for fast and sporty cars.

    With the debut of the Audi 80 quattro in fall 1986, Audi introduced a new center differential – a component that was still strictly mechanical, but highly efficient. The name Torsen was a contraction of the words “torque” and “sensing.” The Torsen differential had already proved itself in the world of technology as a high-tech rear axle differential; Audi developed it further for use as a center differential.

    The Torsen differential is an excellent solution for a longitudinal engine and a drivetrain that runs in a straight line to the back. Audi chose an entirely different technology for the transverse-mounted engines in the compact models – an electronically controlled and hydraulically actuated multi-plate clutch. It first appeared in 1998 in the TT quattro and the A3 quattro.

    In 2005, Audi set off the next stage in the evolution of its classic quattro drive system in the second-generation RS 4. The new self-locking center differential, which is used in many models today, remained true to the principle of mechanical function, yet represented significant progress over the Torsen differential.

    The Audi R8 high-performance sports car occupies a special position in the Audi model range – and this extends to its packaging and its drive system. The mid-mounted engine is arranged longitudinally at the rear of the car in front of the rear axle, with the gearbox right behind it. It also includes an auxiliary drive for a prop shaft running past the engine on the side and up to the front axle.

    The self-locking center differential in the classic quattro drivetrain does an excellent job of distributing the power between the axles. To make driving even more dynamic, Audi introduced an additional component in the dynamic S4 Sedan in late 2008 that actively splits the torque between the wheels of the rear axle – the sport differential.
