The V6 turbo-diesel is a beauty, developing 190kw from a 3.0-litre V6, 10 per cent more than the previous engine with a 15 per cent boost in torque to an impressive 620Nm.
Benz says with a combined consumption of 7.0 litres of diesel fuel per 100km, the S350 BLUETEC beats its predecessor by nearly 1 litre or 9.1 per cent, as well as delivering much-improved performance.
The CO2 emissions likewise have fallen by 8.4 per cent, from 202 to 185g/km.
Yet despite the efficiencies, it can reach 100km/h in 7.1 seconds with a top speed limited to 210km/h.
The Bluetec ranks among the world’s cleanest diesel models with technology developed by Mercedes-benz to reduce emissions from diesel vehicles, in particular nitrogen oxides.
Adblue, an aqueous urea solution, is injected into the exhaust flow, releasing ammonia, which converts up to 80 per cent of nitrogen oxides into harmless nitrogen and water.
Benz says as a result, the S350 BLUETEC already complies with 2014 emission levels.
There is nothing like an S-class with its aloofness and prestigious appearance inside and out. It is restrained, not quite turning heads, yet carries a subtle message of wealth.
While it is extremely economical, we are talking small four cylinder frugality, the V6 turbodiesel is also satisfyingly quick, surging to 100km/h from rest in only 7.1 seconds.
Incredibly, with the engine idling I thought it was the petrol V6. It’s only from the outside that there is a hint of diesel clatter.
It zips around the rev counter with such smoothness and silence that it is extremely unlikely anyone would pick its engine type.
It gets a seven-speed automatic with paddle shifters for those who need something extra.
Despite its near two-tonne weight, it is agile and responsive. Throw it into a fast turn in the country and it will sit down on its air suspension and pick a line with a flat body stance and firm yet satisfying steering feel.
Impressive is the way the 620Nm of torque can be fed through to the rear wheels at mid corner, producing a forceful push as the car exits.
The torque peak arrives at a mere 1600rpm and starts to drift downwards only from 2400rpm, leaving
