At the 2012 Consumer Electronics Show (CES), Audi revealed the interior of the all-new 2013 A3 and as expected this brings some interesting innovations. Some of these include the electromechanical parking brake, which replaces the mechanical component, a new multifunction steering wheel with a freely assignable button but also new infotainment features. The new modular infotainment platform utilizes the Nvidia Tegra processors. The central computer in the modular infotainment platform comprises two units, the the Radio Car Control Unit and what is known as the MMX board (MMX: Multi-Media eXtension).
The latter is responsible for all voice control, online, media, navigation and telephone functions. What is more interesting is that the new modular layout makes it easy to update the hardware – the fact that the MMX board can be replaced keeps the system at the cutting edge of technology. According to Audi, the T 20 processor of the Tegra 2 series from market leader Nvidia is a dual-core processor with 1.2 GHz clock frequency and a fast graphics card.
With its help, the playback of audio and video formats such as mp3 audio and mpeg4 video is accelerated. Moreover, the T20 works with a graphics program (what is known as a 3D engine) from the specialist Rightware and makes Audi one of the first automobile manufacturer able to display three-dimensional graphics in a vehicle.
The new A3 is saved as a data model in the system. Its drivers and passengers can view it virtually in detail and from many angles in the “Car” menu on the MMI navigation plus system. As we said, the new MMI terminal features a touchwheel, which means that it merges the touchpad and rotary pushbutton into a single part for the first time. The handwriting recognition system is of the highest quality, and the large touchwheel moves with high precision, and clicks precisely into place.
In order to offer clear functions, two rocker switches in front of the touchwheel directly operate the most important areas of Telephone/Navigation and Media/Radio. The design is completed by a Menu key and a Back key. Moreover, a new monitor with a 7-inch diagonal with a very high contrast and resolution of 800 x 480 pixels and very sharp 3D graphics is available. The new Audi A3 will also offer the Audi Phone Box, which couples cell phones of any type to the vehicle perfectly. Audi is also planning to offer a wireless charging option.
