The new MBUX infotainment system will be offered in quick order in other Mercedes-Benz models.

According to Ola Kaellenius, head of research and car development at Mercedes-Benz, the new infotainment system will "quickly proliferate" through the company's range, and "within a couple of years" it will be available in every model.

Georges Massing, head of user interaction, later confirmed the MBUX system's hardware and processors can be installed into existing models, and doesn't require a generational change.

The system features two large screens, one ahead of the driver and the other in the centre of the dashboard, both driven by a graphics processing unit (GPU) from Nvidia, a supplier most famous for its gaming and computing GPUs.

For the just unveiled fourth-generation A-Class, vehicles are available with either two 7.0-inch screens, two 10.25-inch screens or a mixture of the two display sizes.

The central unit embraces touchscreen technology, but it can also be controlled by buttons on the steering wheel's right spoke, as well as via a haptic touchpad situated on the centre tunnel.

The screen ahead of the driver, as well as the head-up display, if fitted, is manipulated via controls on the steering wheel's left spoke.

Said to be a ground-up reimagining of the company's infotainment system, MBUX features a new design, and an interface that's only two menu levels deep.

A new natural language voice recognition system, similar to Amazon Alexa, Apple Siri and Google Assistant, is triggered by the key phrase “Hey Mercedes”. It can control most vehicle and infotainment functions, although some driving features, such as active lane changing assist, cannot be triggered via voice.

As Massing points out, it could be quite calamitous if your "kid in back [gives the instruction but] doesn't see that S-Class or AMG car coming in the left lane".

Updates for the MBUX system can be delivered over-the-air, and don't require the car to be serviced.
