AUDI-A4 that will go on sale in the States

Audi A4 has been one of the most successful car models by the brand, Earlier to being named as A4 it was well known as Audi 80. This model was the first model in Audi range to get a fully galvanised body and a ten year warranty against rust of the metal. It single handedly revived Audi as a luxury car manufacturer. The first generation Audi A4 introduced in 1996 was a huge success. Audi A4's captivative Teutonic looks, impressive performance and stylish, well finished interior set the theme for the new Audi models since the 90's. Though it is available as a sedan, convertible and wagon car styles in the western markets, it is available only as a sedan in India. A4 in India is powered by turbocharged engine teamed with a 7-speed multitronic gearbox. The A4 has all the typical Audi luxuries including the a well lit instrument panel and steering wheel with choice of interface mode and multi-media interface and top of line Audio system. A4 comes with three drive model selection. The shooting brake concept offers an impressive amount space and ample knee room. The A4 has a top speed that ranges from 227 km/h to 250km/h depending on the engine capacity. Audi A4 comes with prices starting from Rs 29 lakh.

s fast as a professional rally driver –Audi dynamic steering

The new A4 features yet another pioneering technological development: Audi dynamic steering. Its key element is a superimposed gear system that alters the overall ratio according to road speed and the chosen Audi drive select setting. This concentric-shaft steering gear is extremely compact and light in weight; it has a precise action free from any slack. It was first developed for use in robots and for space travel applications; the expedition vehicles on which it was installed have already traversed the surface of the moon and Mars.

Audi dynamic steering makes the steering ratio more direct at low speeds, with a higher level of power assistance. This renders the steering extremely light when manoeuvring, and only two turns of the wheel are needed from lock to lock. As the car’s speed increases, however, the steering ratio becomes gradually less direct and in parallel with this the amount of power assistance is reduced. At high motorway speeds the A4 can therefore be driven smoothly and has excellent straight-line stability.

Audi’s high-tech steering can do even more. It is closely networked with the ESP and therefore receives precise information about the car’s attitude as the handling limit is approached. If the A4 threatens to oversteer, for instance after an abrupt avoidance manoeuvre, the steering performs slight corrective impulses in the direction needed to reduce this tendency. Such corrective action takes place faster than even an experienced rally driver could react. This rapid response means that brake applications are often not needed, so that the car continues its journey more smoothly and dynamically.

The system also takes action if the car understeers: it selects a more indirect steering ratio for a short time, the aim being to prevent the driver from turning the steering beyond the point at which the tyres still have plenty of road grip. With these capabilities, Audi dynamic steering represents leading-edge technology in this car market segment.

The optional-extra damping control permits individual suspension settings to be chosen. These are based on the lowered sports suspension. Continuously adjustable hydraulic shock absorbers permit the damping characteristic to be varied individually at each wheel. This means optimal contact between the tyre and the road in almost every situation, for greater safety and more dynamic road behaviour.
