Mercedes Benz S Class Review

Mercedes Benz S-Class ReviewMercedes Benz S-Class Review  | Part Two

Some cars riding on big tyres tend to rumble, but there is no evidence of that here....

Comfort and Refinement

This car excels on the refinement front. It is truly excellent, blissfully hushed and with very low noise levels. The engine does not make a lot of fuss about its operation, and what noise there is has been well insulated from intruding into the cabin. The S Class’s sleek, sculpted shape means that air flows cleanly over the bonnet, with the result that there is minimal wind noise even at speed.

Some cars riding on big tyres tend to rumble, but there is no evidence of that here. You have to be on an unusually high noise-generating road surface to notice much sound from under the wheels. It is an all-round superbly quiet car.

Safety and Security

You are hugely well protected in an S-Class. There is the predictable array or airbags, an active pop-up bonnet system to protect any pedestrian unlucky enough to be in collision with this very large car. The anti-lock brakes have brake assist to enhance their effectiveness, and there is also an autonomous emergency braking system that does the job of stopping the car for you if you fail to react quickly enough to an obstacle ahead.

There is a drowsiness detection system to warn if the car's sensors react to signs of the driver becoming fatigued. The door mirrors are not just electrically-operated, heated and power-folding, they also have an auto-dimming device to prevent glare from a following vehicle at night. There is a pre-crash system that tensions the seatbelts and readies the car’s safety systems if sensors anticipate an impending crash.


The S-Class comes well-equipped with good multimedia facilities. It has a DAB digital radio with CD and DVD with a 10 GB hard drive. There are SD card readers, USB sockets and steering wheel controls. Bluetooth mobile phone connectivity with audio streaming is also supplied. Sound quality is excellent, and audio upgrades are available for the very pernickety.

What We Liked
  • Lavish performance
  • Superb refinement, really quiet and civilised
  • Absolutely packed with the latest technology
  • Silky seven-speed auto transmission
  • Limousine ride quality, glides over a bumpy surface
  • Lots of room to stretch out inside the car and loads of seat adjustment
  • Huge boot at 500 litres
  • Sumptuous cabin, beautifully crafted and cosseting with top-notch quality
  • Wonderful clarity of the instrument display, with precision graphics
  • It’s a very big car but still has 50+ mpg on the combined figure
  • Huge list of available options
What We Disliked
  • Dearer than key rivals, such as the Audi A8
  • Lots of options but they quickly push up the price even further
  • Insurance cost, it’s right at the top level of the ABI-Thatcham scale
  • Smaller fuel tank, at 70 litres, than some rivals, so range not as great
What We Would Like To See
  • A spare wheel. It only comes with a tyre repair kit.

By any standards the S-Class is a class act. It is beautifully designed and superb quality, with very strong performance whichever engine you go for.
