Mercedes-Benz is confident that changes in construction, updates to mechanical and electrical systems and a greater emphasis on quality will see the new four-wheel-drive M-Class match sales of the first-generation model, which have crept past 500,000.
A computer-enhanced picture of the new off-roader is above. It is due in 2005 and
will have a car-like body - which should translate into something resembling car-like handling - and should answer the criticism levelled at the current model about average driving dynamics.
The present model's on-frame construction will give way to unitary build, a more contemporary technique that promises significant weight savings.
It also gives a much stiffer body structure to improve ride comfort, enhance refinement and increase crash protection. Mercedes-Benz is also pulling out all stops to ensure the next model delivers in the rough stuff.
A new multi-link rear suspension will allow greater wheel movement, while a modified version of the carmaker's latest Airmatic air spring system will have nearly 300mm of ride height adjustment.
The current model's electronically controlled four-wheel-drive system has had a comprehensive overhaul to improve traction in extreme off-road conditions.
Electro-hydraulic braking in the new model provides the basis for an improved "creep" function, similar to the Hill Descent Control used by Land Rover and BMW.
Initially, the 3.7-litre V6 and 5-litre V8 engines will carry over in the new model. New four-valve V6 and V8s are due later.
