For a 2.9-litre diesel in a two-tonne limo, that’s ridiculous, although not as ridiculous as the 335bhp version that goes on sale next summer. That one, albeit with the aid of four-wheel drive, knocks that figure to 5.2sec. When I started in this business, the only Ferrari on sale that could beat that figure was an F40.
The other major enhancement is the adoption of the next generation of autonomous driving technology. With this, the S-Class will drive itself on a much greater number of roads with no driver input, save a vestigial touch on the steering wheel every few seconds.
By co-ordinating its radar with its navigation data, the car knows to slow for corners if the approach speed is too high or if a roundabout is looming, or it can brake to a halt for a toll or junction. When you arrive at a parking space too tight for you to get out of, you can stand outside the car and park it with an app on your phone.
Inside, there is an entirely new dashboard featuring twin 12.3in high-definition TFT screens that can display what can at times seem like a limitless amount of information.
If you don’t like the look of your instruments, you can change them with a turn of the controller. You can choose any one of 64 colours with which to illuminate your interior and, if you are prepared to pay for the option, you can benefit from what Mercedes calls ‘Energising Comfort Control’.
This is a service that co-ordinates the climate control, fragrance dispenser, seat heating, cooling and massage, wall heating, music and interior lights, allowing you to choose certain presets according to either your mood or the one in which you’d like to be. Mercedes calls these ‘Freshness’, ‘Warmth’, ‘Vitality’, ‘Comfort’, the rather ambitious ‘Joy’ and the faintly implausible ‘Training’. If you check the date this has been posted, you will see I am not joking.
