Self Study Program 990143 – The 2015 Audi A3 Introduction

VAG SSP 990143. 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 vehicles were sold. The second generation, launched in 2003, was even more successful, achieving sales of approximately 1.8 million vehicles.

With the newest generation of the A3, the Group has set itself the goal 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 the vehicles with the latest technical innovations. The basis for implementing these objectives is the MQB or “modular transverse platform”, a standardized architecture in 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 2015 A3 sedan represents the cumulative technological expertise of Audi in a compact format. In its lightweight body, its interior architecture and its user interfaces, the A3 sedan will once again set standards in its class. Its engines impress with their efficiency and power, and the range of driver assistance systems and infotainment solutions is unparalleled in the premium compact class.

The lightweight body and newly developed engines have had major consequential effects throughout the vehicle, reducing the weight of many suspension, exhaust and interior components. At launch, the vehicle will be offered with two recently refined engines from the EA888 family. The Modular Infotainment Platform (MIB) makes its debut in the A3 sedan. It represents a big step forward in mobile communication electronics.

The A3 also sets new standards in the premium compact class when it comes to driver assistance systems. One of the most important of these is Audi pre sense. In the event of an impending collision, the system warns the driver in progressive stages and, if necessary, can initiate partial braking in order to reduce the car’s speed at impact.

The Audi A3 and S3 sedans are assembled in Gyor, Hungary. The site in northwestern Hungary is one of the largest automobile factories in the world. This is where Audi has assembled the TT coupe, and in the near future will assemble the A3 cabriolet. It is an ultra modern facility with the capability of complete production work—from stamping to final assembly.
