On the move on snow and ice with Mercedes-Benz and Setra

The results of the extensive tuning test drives on snow and ice are impressive. This can literally be experienced in reality in the Arctic Circle based on elements of the Omniplus driving safety training. Be it full brake application on sheer ice, different friction coefficients on the left and right (µ-split), driving in a circle at different speeds on ice, spectacular evasive manoeuvres with single or even double lane changes based on the model of the VDA obstacle avoidance test – the Mercedes-Benz and Setra buses reliably cope with even the most demanding of tasks and precarious situations. And, above all, the intensive tuning work ensures that the vehicle always reacts in the way the driver expects. This applies to all vehicles, from minibuses right up to super-high-deck touring coaches.

As proven by the agile Mercedes-Benz Sprinter Travel 65 minibus. It features the Sprinter's suspension system, which is tuned with the emphasis on both safety and comfort. The compact Mercedes-Benz Tourismo K is not only amazingly manoeuvrable thanks to its short wheelbase, it is also reassuringly reliable in all driving situations thanks to its cleverly thought-out axle load distribution and precisely tuned safety and assistance systems.

The Mercedes-Benz Travego fully lives up to its billing as a "Safety Coach", even on snow and ice: aided by all currently available safety and assistance systems, the 12.18-metre-long premium high-decker is an astounding performer, even on glass-like road surfaces. The same applies to the alluring Setra TopClass S 516 HDH super-high-decker – a three-axle vehicle that combines luxury and safety at the highest level, even in highly adverse road conditions.

Bus-specific tuning takes priority

Here the focus is on bus-specific fine tuning alongside general functioning. Directly transferring systems from top-selling trucks would be far too easy for Mercedes-Benz and Setra. After all, a bus not only handles very differently to a truck because of its size, weight, axle configuration and speed profile, but also on account of its "cargo": passengers.

That's why the maximum braking pressure provided by Active Brake Assist in Mercedes-Benz and Setra buses is applied gradually rather than instantly - to take account of any standing passengers. Fine-tuning of this kind requires a great deal of work: the bus testing team needed two winters to perfect the new AEBS (Advanced Emergency Brake System), for example. Including the summer tests performed in the period from spring through to autumn between these two winters, this amounts to one-and-a-half years of intensive testing.
