In addition to the standard technologies, the Audi A3 sedan will feature new, segment first technologies. One key example is the implementation of the new NVIDIA graphics processing unit (GPU). The NVIDIA GPU generates complex three-dimensional images used in all online, voice control, media navigation and telephone functions. Fundamentally, the Tegra® graphics processor powers tablets and other mobile devices and is also used in 3D gaming and various medical applications. Another industry first includes the Audi phone box. The Audi phone box is a compartment located under the center armrest that boosts a mobile phone's cellular coverage by wirelessly coupling to a specialized antenna in the rear windshield.
The A3 sedan has been further enhanced thanks to numerous engineering improvements under the hood. The A3 model line offers four different engine variants including the 170 horsepower 1.8 TFSI, and 150 horsepower 2.0 TDI clean diesel, and a low and high-output 2.0 TFSI used in the A3 quattro and S3 quattro respectively. Horsepower figures for the 2.0 TFSI engines will be available closer to launch. All engines are mated to the standard 6-speed S tronic® transmission which provides the driver immense shifting flexibility and driving pleasure with smooth, dynamic acceleration and virtually no interruption to the power flow.
New to the A3, the Audi drive select allows the driver to adjust throttle response, shift points, and the electromechanical steering effort. Similar to other Audi models, Audi drive select has four settings that include Auto, Dynamic, Comfort and Individual.
The new platform allows the front wheels to move forward by roughly 1.5 inches (compared to the previous generation A3) to provide well-balanced proportions, supplemented by optimized interior space utilization, and an improved crash structure.
The front suspension is a MacPherson design with A-arms and aluminum pivot bearings. It is joined to an aluminum subframe. The electromechanically assisted steering system operates sensitively and efficiently together with various assistance systems, while reducing mechanical drag for greater efficiency. In the four-link rear suspension for the gasoline models, which utilizes a steel crossmember, the springs and shock absorbers are mounted separately.
The electronic stabilization control (ESC) also includes an electronic differential lock. When driving through curves, it can brake the inside front wheel very slightly to help minimize understeer and improve traction.
The exterior has been completely redesigned and specifically tailored to meet the sedan preferences of the American market. The Audi A3 stretches 175.5 inches in length and has a 103.4 inch wheelbase. Combined with its 70 inch width and 55.7 inch height, its proportions are compact but very sporty and nearly resemble the original Audi A4 from 1994.
The signature Singleframe® grille and available full-LED headlights, another first for the A-segment, are some of the notable design changes included in the all-new Audi A3 sedan.
The athletic exterior of the A3 extends inside, where Audi maintains its leading role in automotive interior design and craftsmanship. The defining element is the "wraparound" dash design, which incorporates an innovative three-dimensional inlay concept surrounding the driver and front passenger. The available LED interior lighting package highlights the immense craftsmanship and attention to detail that goes into every Audi A3 interior. This is accomplished by bathing the interior in a cool white LED light surrounding the center console, door panels, cupholders, and even the Bang & Olufsen Sound System when so equipped.
