Merc’s C63 AMG tallies a fearsome amount of V8 power in a small executive package. Now Carlsson has added 108 imperial units of extra power.

Carlsson showed off renderings of the CK63S late last year. Now a rolling example is prowling the streets of sleepy Merzig in southern Germany where the bespoke Mercedes-Benz tuner is headquartered. This is one custom car project that is no longer a trailer queen...

Those wheels might be more than a third lighter than AMGs, but they're still not especially pretty.

From the screen renderings to full production, styling embellishments, consisting of a regulation front spoiler embedded with mesh and surprisingly subtle rear spoiler to keep the aft axle stable at high speeds, have remained generally true to the original design.

As bespoke as the body kit appears, it’s worth remembering the material surfacing is a blend of Polyurethane and carbon-fibre, not a pure weaving of the latter as one would expect in such a highbrow conversion…

Those busy, 19-inch, multi-spoke wheels, which are 38% lighter the C63 AMG’s conventional alloy wheels, were signed off for production too – unfortunately.

Big, natural numbers...

Numbers are everything to the German aftermarket tuning industry, and the Carlsson CK63S has liberated an optimal increase in power from the 6.2l AMG built V8.

Producing 415kW and 685Nm, the Carlsson fettled engine overpowers the standard car by 79kW and 85Nm. For a naturally aspirated unit it's very impressive reading indeed.

With a limited-slip differential keeping traction as tidy as possible off the line, the CK63S blitzes from standstill to 100km/h in 3.8 seconds - which is peculiarly deep into production supercar territory.

As is their right being an aftermarket engineering company, Carlsson are not bound by the German 250km/h blanket speed limiting agreement - subsequently electronic control unit modifications usher in a 300km/h top speed.

Four-door supercar certified by a woman?

To ensure the treacherous amount of additional power and torque doesn’t chaperone customers into haphazard road furniture or barriers at the first application of injudicious throttle and steering lock, the optional multi-plate limited slip differential (pretty much essential), with variable rate lock-up, is backed up by a clever coil-over suspension system.

With the limited slip differential keeping things tidy at low to medium speeds, high-speed stability is sorted thanks to the RS sourced coil-over suspension kit, encompassing individually adjustable dampers.

Tested by female DTM racing ace Ellen Lohr, Carlsson engineers have optimised the median damper settings to find a golden mean between traction and ride-quality, dovetailing perfectly with the CK63S’s long-distance touring capability.

As far as purchasable, naturally aspirated German four-door supercars go, Carlsson now have bragging rights…for a while.
