Self Study Program 609 – Audi A3 2013

VAG SSP 609. The Audi A3 can look back on a 16-year success story. The first generation of the series, which debuted in 1996 as a three-door, established an entirely new market segment – the premium compact class. In 1999 the five-door hatchback and the sporty Audi S3 completed the family. In total, around 990,000 units were sold. The second generation, launched in 2003, was even more successful, achieving sales of around 1.8 million units. In the emerging competition, the A3 was the dominant force in the premium compact class.

The Group has set itself the task of improving the fuel economy of its internal combustion engines, extending its product range to include alternative drive systems such as natural gas engines and electric motors, and equipping as many vehicles as possible with the latest technical innovations. The basis for implementing these objectives is the Modular Transverse Platform (MTP), a standardised architecture on which various vehicle components can be combined in any configuration on modular principles. This broadens the diversity of the model range, resulting in more efficient production, engines and combinations of materials.

The Audi A3 ’13 represents the cumulative technological expertise of Audi in a compact format. In its lightweight body, its interior architecture and its user interfaces, this three-door model is once again setting standards in its class. Its engines impress with their effi ciency and power, and the range of driver assistance systems and infotainment solutions is unparalleled in the premium compact class.

The progressive formal language visualises the sheer passion with which Audi develops and makes cars. Ultra-lightweight design has long been a success formula and a hallmark of the Audi brand. This is by no means confined to a single, specific material. On the contrary, Audi’s motto is: “The right material in the right place for optimal function”. True to this maxim, the engineers have developed a multi-material body for the new A3.

The lightweight body and downsized engines have had major knock-on effects throughout the vehicle, reducing the weight of many suspension, exhaust and interior components. At launch, Audi will supply the A3 ’13 with one TDI engine and two TFSI engines. The Modular Infotainment Platform (MIB) makes its debut in the Audi A3 ’13 – it represents a big step forward in mobile communication electronics. The Audi A3 ’13 also sets new standards in the premium compact class when it comes to driver assistance systems. The most important of these is Audi adaptive cruise control. In the event of an impending collision, the ACC system warns the driver in progressive stages and,if necessary, can initiate partial braking in order to reduce the car’s speed at impact.
