The sports differential enables the quattro system to not only transfer torque between the front and rear axles to counter traction losses, but also between the rear wheels. When the steering wheel is turned or the car accelerated in a corner, power is redirected in a controlled manner to the outer rear wheel, literally pushing the car through the corner. The driver benefits from reduced steering effort and a feeling of even greater adjustability and control.
The upgrade from 'standard' quattro to quattro with active sport differential is available at extra cost as an element of the optional Audi drive select adaptive dynamics system. Audi drive select enables the driver to fine-tune throttle response, steering assistance and transmission shift points (where S tronic is fitted) via dashboard-mounted buttons to suit personal preferences or prevailing road conditions.
Three distinct Audi drive select option packages are available in the new Audi A5 Cabriolet - Audi drive select with damper control for even greater suspension adaptability to the road surface, Audi drive select with dynamic steering allowing alteration of the actual ratio of the steering for optimum feel and, specifically for quattro models, Audi drive select featuring the sports differential. For maximum driver rewards it is possible to combine dynamic steering and damper control or, in quattro models, dynamic steering and the sports differential.
Audi A5 Cabriolet customers will be able to equip their cars to Standard, SE or S line specification, all options including fully automatic powered soft-top operation, alloy wheels and climate control. SE models add luxuries such as full leather upholstery, and on top of this S line specification makes the most of the sharply sculpted lines of the A5 through exclusive grille and bumper treatments and larger 18-inch alloy wheels. Xenon headlamps with LED daytime running lights, LED rear lights and the acoustic hood upgrade incorporating in-built LED rear reading lights are also part of the S line package.
In addition to Audi drive select, the options list for the new Audi A5 and Audi S5 Cabriolets also offers driving assistants including adaptive cruise control, the Audi side assist blind spot alert system and the Audi lane assist lane departure warning system. It also includes luxury entertainment and convenience features such as a 505-watt Bang & Olufsen audio system and a new third generation version of the Multi Media Interface infotainment control system. Available exclusively in conjunction with satellite navigation, MMI 3G offers even more intuitive control and further improved graphics via a high resolution colour display. Its inbuilt navigation technology derives its information from a hard disk drive, dramatically boosting the level of detail offered by the maps compared with DVD-based systems. The hard disk can also store MP3 files for music playback.Published 3 December 2008
