Mercedes-Benz debuts GLK-Class at Auto China 2008

With its poised, confident presence, the mere look of the GLK-Class leaves one in no doubt about its intent to conquer the compact premium SUV segment. It is arguably the most sophisticated of all takes on this particular theme. And it displays echoes of the G-Class, the founding father of the Mercedes-Benz SUV family. Design chief Prof. Peter Pfeiffer takes up the story: "With the G-Class we created a style icon that has been a benchmark in SUV design for the past 30 years. Combining this bold concept with the latest Mercedes-Benz design idiom makes the GLK a vehicle of genuine character."

No other model in the compact-SUV segment, past or present, comes close to matching the GLK's distinctively expressive appearance. The body is beautifully proportioned (length 4528 mm, width 1840 mm, height 1689 mm), while there is a special allure in the interplay between the classic angular shape and the typical design features found in all contemporary Mercedes-Benz passenger cars. Here the unmistakable design idiom, consisting of taut lines and large, expansive surfaces, is combined with the typical body features of a practical off-road vehicle, such as short overhangs, an upright front end, slim roof pillars, a steeply raked windscreen and taut roof lines.

Rather than being a stylistic end in itself, however, the body design allows the typical advantages of an off-road vehicle to be introduced to the more road-oriented compact-SUV category for the first time. Large angles of approach and departure plus good ground clearance make off-road ventures a sheer joy. The outstandingly clear layout of the body and good all-round visibility, combined with the raised seating position, enhance everyday practicality and ensure relaxed driving, even in dense city traffic.

Superlative ride comfort, outstanding handling dynamics and excellent off-road performance

The AGILITY CONTROL suspension on which the GLK-Class is founded displays a high level of flexibility and resolves a conflict of aims that particularly affects the SUV class, where chassis engineers want to create a vehicle that is both sportily agile and comfortably smooth yet one which can also cope with off-road terrain. If the focus is on sporty, active handling, the suspension and, above all, the shock absorbers need to display a certain firmness, which precludes access to the brand's typical suspension comfort and limits the off-road options. If the vehicle is set up with softer dampers to ensure suspension comfort and off-road capability, dynamic handling naturally suffers.

The solution is "amplitude-dependent damping". In this system, the damping forces of the shock absorbers are configured to respond flexibly rather than lineally. In normal driving mode on moderately contoured roads or during slow off-road manoeuvres, the system responds softly, enhancing both the occupants' comfort and the vehicle's off-road capability. To ensure that this level of comfort is maintained when driving hard or performing abrupt evasive manoeuvres, in these situations the dampers deliver a harder performance, ensuring optimum handling stability.

At the same time, the driver of the GLK is supported by speed-sensitive power steering, specified as standard for the V6 models, which provides the optimum level of steering assistance for the situation in hand. Parking and off-road manoeuvring are made much easier because maximum power assistance is available. At higher speeds, the assistance is reduced in favour of greater handling stability.

All the base models in the GLK series are fitted with 17-inch, size 235/60 R 17 light-alloy wheels. In conjunction with the exterior sports package, which is included as standard when the car first comes onto the market, or the off-road styling package, all models are shod with mixed-size tyres which, together with the AGILITY CONTROL suspension and the asymmetric power distribution between the front and rear axle, form the basis for a even better transfer of power between the wheels and the road.
