Mercedes GLS 400d in the test

The S-Class among SUVs is said to be seven-seater, and with a 330-horsepower diesel it is also particularly efficient. Well: the test.

A certain fatalism can certainly be read, because even in 2019 it was partly appropriate to celebrate an increase in length by 7.7 cm in a new car – to 5.21 meters. In any case, Mercedes did just that and was also pleased that even in the back row of seats there is now enough space for people up to 1.94 meters in height. There is no half-measures, obviously a claim to the GLS. So why is it not in the AMG 63 variant? Well, we don’t want to overdo it either.

Somehow, a straight-six diesel engine with a maximum torque of 700 Nm seems suitable for this spacecraft. Honestly, this is true for the entire spaceship. why not? If you can and want to afford it? merely. Especially since the space is really spacious – with two small restrictions. With passengers measuring 1.94m tall in the third row, this can only be achieved without bumps in the hairstyle if it weren’t for giant seats. In the second row, on the other hand, it is surprising that when the center seat backrest is folded down and the child seat is installed to the right or left of the seat, the belt buckle is practically inaccessible – not even for a child. On the other hand, seating comfort should outweigh that of most living room furniture, and the driver and front passenger also have decent lateral support.

Advanced structure technology

The Mercedes GLS offers excellent suspension comfort and safe driving characteristics.

Do you need it? Well, the GLS can be driven through corners with great commitment, and that’s because an all-nuclear power plant runs on chassis technology: in addition to the standard air suspension, E-Active Body Control is on the price list, and it’s a 48-volt active chassis, so it runs especially fast. . It reduces not only rolling motions, but also swinging and rising motions. In addition, the chassis processes data from the front camera, preparing itself, so to speak, for bumps. All this works with remarkable ease, because the reactions of the car always seem natural, depending on the steering angle and cornering radius.

Abnormal on the other hand: a curve tilt function to reduce lateral forces. MUCH BETTER: Triggers from waves, potholes, and distortions are usually lost somewhere between 21″ wheels and benches, only very bad road decay causes boring blows away, like a medicine ball falling on a gymnastics mat.

Too much weight, too much energy, too little consumption?

The six-cylinder diesel engine fits the GLS very well with its primacy and efficiency.

Matching: a far blow of the OM-656 diesel engine with a displacement of 2.9 liters. Its D29-SCR version with high-pressure and low-pressure combined charging powers the 2,618-kilogram GLS with a kind of middle-class nonchalance. On the one hand, the SUV accelerates from zero to 100 km / h in 6.6 seconds, and on the other hand, the test consumption does not exceed 10.2 l / 100 km. But more often than not, you drive in such a way that the gently shifting nine-speed automatic barely allows for more than 2,000 rpm.

It is noticeable that the wind bypasses the A-pillar with a strong presence, but above all this consumption again decreases: 7.9 l / 100 km is possible. Given the convenience, security features, and available space, you can celebrate this without much.

At most, wind noise stands in the way of your claim to luxury, but not the excellent suspension comfort, precise equipment, safe driving characteristics, efficiency and supremacy of the diesel engine.
