When Mercedes throws its entire might into high-tech support for luxury and safety

# data.attributes.metatag[].attributes.content.reviewBody[]
the results are so dazzling that it's hard to know where to begin.Try this. I'm telling myself to ignore a speed bump ahead and hit it at about double the sensible speed

# data.attributes.metatag[].attributes.content.reviewBody[]
puckering myself as it passes beneath the bonnet. Ha! The inevitable brutal shock never materialises. Binocular-vision cameras in the windscreen have seen the bump

# data.attributes.metatag[].attributes.content.reviewBody[]
causing the fully active suspension to lift each wheel at the exact moment it's due to meet the tyre. Not just softened off a spring or damper

# data.attributes.metatag[].attributes.content.reviewBody[]
but actively lifted the wheel. The disturbance is what you'd expect from driving over a couple of catseyes. Now

# data.attributes.metatag[].attributes.content.reviewBody[]
I'm not suggesting you clatter through traffic-calming at car-chase velocity

# data.attributes.metatag[].attributes.content.reviewBody[]
because a kid might run out from the school gate (although the S-Class also has pretty effective pedestrian recognition and autonomous emergency braking). I'm just saying that the new S's optional Magic Body Control does astounding things for comfort over large bumps and potholes.Or how about this? We're in sluggish traffic

# data.attributes.metatag[].attributes.content.reviewBody[]
down a curving street with traffic lights. I set the adaptive cruise control

# data.attributes.metatag[].attributes.content.reviewBody[]
touch the throttle and the Mercedes sets off. I remove my hands from the wheel and my feet from the pedals. The car keeps steering

# data.attributes.metatag[].attributes.content.reviewBody[]
accelerating and stopping to keep its place behind an Audi. It's building a map of the situation using those stereo cameras as well as three different radar frequencies. This is not a closed-test-track experiment

# data.attributes.metatag[].attributes.content.reviewBody[]
by the way - it's real traffic on a real rainy weekday afternoon. At one point

# data.attributes.metatag[].attributes.content.reviewBody[]
a Suzuki Swift dives in front of me. The Benz obligingly makes way

# data.attributes.metatag[].attributes.content.reviewBody[]
the supermini dodges back into the adjacent lane

# data.attributes.metatag[].attributes.content.reviewBody[]
and the Mercedes heads off after the Audi. I haven't touched the throttle or brakes yet. I have wobbled the wheel occasionally

# data.attributes.metatag[].attributes.content.reviewBody[]
but only when the car flashes up a warning to remind me it isn't an autonomous driving system. Oh no

# data.attributes.metatag[].attributes.content.reviewBody[]
so if I refused to play my part every 10 seconds or so

# data.attributes.metatag[].attributes.content.reviewBody[]
it would shut itself down.As with the speed-bump stunt

# data.attributes.metatag[].attributes.content.reviewBody[]
I'm not advocating you drive without due care. For a start

# data.attributes.metatag[].attributes.content.reviewBody[]
the self-steering does occasionally lose the plot

# data.attributes.metatag[].attributes.content.reviewBody[]
you're probably bearing down on a kerb or a lorry in the next lane. And in the time it takes to refocus your attention from texting or daydreaming and grab the wheel

# data.attributes.metatag[].attributes.content.reviewBody[]
you'll probably have had the accident. Which means that absenting yourself entirely from the driving is scary rather than relaxing. But allowing it to support - not replace - you does ease the strain to a surprising extent.And easing the strain is what the S is all about. This is one of those cars that

And easing the strain is what the S is all about. This is one of those cars that, over generations, has always defined its market, leaving rivals benchmarking themselves against it and finding spurious points of difference. It knows what it is and plays to its strengths. Relaxed, safe, cosseting, swift.

So while the technologies dominate your thinking about the new S, it's important to remember they're bolted onto what is, at heart, a very fine luxury barge. The self-driving kit and Magic Body Control are a £6,600 hit to the S500 L, but the car isn't sparse without. Even the base S350 diesel has a cabin of lavish plushness, equipped with two 12.3-inch hi-res screens, air suspension, navigation and internet, and even a lighting system consisting entirely of LEDs - headlamps, cabin lamps, everything.

The design of the outside has an elegance that isn't apparent in photos. It avoids the brutally dictatorial aspects that characterised some of its predecessors. Inside, it's not really to my taste - too ornamental and a bit Fifties in its palette of curves and surfaces - but it's done with a conviction that carries the day.

Hit Sport, and the Magic Body Control turns off, but it's still not jarring. In corners, things firm up, the roll disappears and the understeer is cancelled. It's not engaging, but it'd be rapid enough for getting away from a diplomatic incident.
