GETTING A GRIP ON YOUR DRIVING

The key electric control system for the AWD Mercedes Benz Sprinter is called ADAPTIVE ESP® /4ETS. It is activated when one or more wheels begin to lose traction on a slippery surface. The system automatically applies the appropriate braking force to each of the spinning wheels and simultaneously increases tractive power to the wheels which still have sufficient grip, resulting in a significant increase in traction. ESP® plays a pivotal role in controlling your vehicle in measuring and responding to the vehicle’s load condition.

With selectable All-Wheel Drive your motorhome is in its element on roads that alternate between normal to difficult, using rear-wheel drive for standard operation and selectable front-axle operation at the push of a button. You can also select this function when the vehicle is moving (at speeds of around 10km/h).

4ETS & ADAPTIVE ESP® 4ETS

The 4ETS electronic traction system permanently monitors the speeds of all drive wheels and adjusts them if necessary. At the first sign of wheel spin when accelerating or negotiating a slope, 4ETS applies brake pressure to the wheel or wheels concerned. This transfers more power to the wheels that still have sufficient traction. 4ETS therefore dispenses with the need for conventional centre, front and rear differential locks.

When braking or cornering, 4ETS and ADAPTIVE ESP® act as a team. At the first sign of wheel lock or if the vehicle threatens to lose traction and skid, ADAPTIVE ESP® stabilises the vehicle by applying precisely metered braking to one or more wheels and/or adjusting engine torque. This keeps the vehicle on track and, at the same time, can reduce stopping distances. ADAPTIVE ESP®/4ETS thus reduces the risk of skidding and, within physical limits, optimises traction.

LOW-RANGE DRIVE RATIO

The low-range drive ratio enhances operational versatility on difficult terrain. An intermediate gear in the transfer case reduces the transmission ratio between engine and wheels by around 40%, with a corresponding increase in drive torque. This makes it possible to manoeuvre extra slowly and sensitively.
