The tiptronic transmission system is a form of automatic transmission available on selected Audi models with quattro permanent all-wheel-drive. The technology converts high-torque engine power into both sporty performance and operating convenience, with crisp, fast gear changes, reduced weight and an optimised gearshift strategy. More spontaneous gear changes are a particular benefit, especially when down-shifting. Both in the ‘D’ (Drive) and ‘S’ (Sport) programme, the advanced electronics used in tiptronic respond efficiently to every driver input, helping to prevent unwanted upshifts when cornering.

Vorsprung durch Technik: quattro® technology stands for permanent power to all four wheels distributed between the front and rear axles. Power to each axle leads to a low power requirement with very well balanced handling. The advantage: better traction during acceleration and greater safety thanks to exceptional road holding – even in conditions where two-wheel-drive vehicles lose grip.

The special Audi expertise that goes into the quattro® permanent four-wheel drive guarantees more driving pleasure – especially on slippery road surfaces. If the wheels of one axle lose grip and threaten to spin, the drive torque is redirected in the central differential to the other axle, automatically and continuously. The quattro® technology takes into account the influence of the engine speed and torque, the wheel speeds and the forward and lateral acceleration. The result: better acceleration, greater lateral stability, improved traction, higher safety and even more driving pleasure.

Sophisticated, classic and with outstanding functionality: the optional fully automatic acoustic hood substitutes a thick 16mm foam layer in place of the standard cushioning pad. The result is extra heat insulation and a reduction in wind noise to nearly the same level as the A5 Coupe. It is available in four colours and includes rear LED reading lights.

The acoustic hood is standard on S line and S5 models.

Aerodynamic performance plays a vital role in reducing fuel consumption. Every Audi prototype spends over 1,000 hours in the wind tunnel undergoing improvements. Streamlined for efficiency, the cars produce less air resistance, improved handling, better stability and lower CO2 emissions.

The distinctive, sporty Audi design looks incredible and performs brilliantly. Endless fine-tuning produces record drag coefficients, low uplift and an efficient undercarriage. The new Audi A4 has achieved a drag coefficient of only 0.27 proving that our sophisticated aerodynamics set the standard.

Using the satellite navigation data, the optional Adaptive cruise control knows exactly where the car is, so if travelling on a motorway and the car in front brakes and indicates left (because the driver wants to take the next exit) the system can recognise this - thanks to the camera image and because it sees the exit on the navigation data.  In this scenario a traditional radar based cruise control system would brake, whereas the A8 would continue uninterrupted.
