New Mercedes-Benz S 350 CDI review, test drive

The 3.0-litre diesel V6 is as you can expect from a Mercedes, and with 255bhp and 63.2kgm to haul the car around, is pretty brisk too. As is befitting a car of its stature, there’s no solid shove from the motor, but instead a smooth long surge that seems to go on and on. The mid range is particularly strong and allows you to reach silly speeds without realising, before you run into the somewhat low 4,200rpm redline. The seven-speed automatic works well for slow driving and highway cruising, shifting gears unobtrusively. Set the car to sport mode and the engine responses and gearshifts quicken, but it’s here that you notice that Mercedes’ 7G-Tronic torque converter auto is not quite as quick, clever or responsive as some of the more modern luxury gearboxes around.

 

 

Otherwise the new S-class is luxury car travel at its brilliant best. Once you sink into those big seats and shut the doors after you, you’re in your own world. The attention to detail is breathtaking – the wood and chrome look like they belong together, the graphics on the multi screen COMAND system make you feel you are piloting an Airbus A380, and quality levels are right up there with Bentley. Getting into the rear of the car is even nicer. You don’t get the same split rear cabin as the petrol, but the two individual electric ‘seats’ that form the bench are still reclinable, heated, cooled and massaging. They don’t recline as far back as in the petrol, but they’re still super soft and comfortable, and the ability to move the front passenger seat forward 77mm for truly excessive legroom is still available. What’s more, flip up the centre armrest and there’s room for a third passenger as well. Now, apart from the super-luxury rear seats, some of the kit from the petrol version is missing from the S 350 CDI, but it’s nothing of tremendous consequence to the luxury experience. There’s only a rear camera instead of the 360-degree setup, the wood trim is missing from the steering wheel, the 18-inch alloy wheels are different, the boot lid isn’t power operated, there’s no night vision system, and the Burmester hi-fi system is a few speakers down (it still sounds phenomenal though).  No car in the world blends high technology and old world charm quite like the new S-class, and that’s evident on this diesel as well.

 

 

And is there any doubt, technology flows thick through the veins of this car. The new aluminium chassis is super light, the incredibly slippery shape allows the S to slide through the air uninstructed, and the long wheelbase and the air suspension make the car float serenely over all manner of bumps. We rarely came across a surface that disturbed the calm inside the cabin. Really deep potholes did thump through though, and there is a hint of road noise on coarse surfaces, but other than that the ride is fantastic. There are two settings for the Airmatic air suspension – Comfort and Sport. In the former, the ride is really cushy, but as can be expected, there’s a fair bit of float. This is also because the car has been raised for the Indian market.  So, even when you put it in Sport, although things firm up, there’s still quite a lot of body movement.
