What is it?
You know the C43 – it’s the link between a mainstream C-Class range dominated by 2.0-litre engines and the full-blooded V8 barnstormers built by AMG in Affalterbach.
The reason we’re driving it again is because for 2018 the entire C-Class range is being given a facelift. For the C43 that means greater power, some tweaks to the styling and a touch more flair within its overly sporting cabin, largely by way of a new digital instrument binnacle.
These are subtle changes, mind. The output of the 3.0-litre V6 increases only from 362bhp to 385bhp, thanks to larger turbochargers (mounted in traditional fashion outside, rather than within, the vee of the cylinders) that operate at higher boost pressure. Torque increases not a jot, remaining at a healthy 383lb ft, though it is now fed into the C43’s all-weather 4Matic driveline 500rpm later in the rev-range, at 2500rpm. It’s a recipe that has made this particular model something of a runaway sales success.
It also means the car’s 0-62mph acceleration figures remain unchanged, at 4.7sec for the saloon and coupé and 4.8sec for the estate, which is quick enough so long as you can forget the fact a C63 demolishes the same measure in 3.9sec. Meanwhile, combined fuel economy is rated at 30.4mpg for the saloon, which is enough for a range-nudging 450 miles.
