The folks over at Brabus have been rather busy of late, having recently revealed the Smart ForTwo-based 125R and then its take on the new G-Class. The latest model to come in for some attention from the Bottrop-based tuner? None other than the Mercedes-AMG GLC63 S 4Matic+…

Of course, Affalterbach’s angriest GLC isn’t exactly short on oomph in standard guise, with its twin-turbo 4,0-litre V8 churning out 375 kW and 700 N.m. For the record, that's enough for a claimed 0-100 km/h of just 3,8 seconds and an electronically limited top speed of 250 km/h.

Brabus, however, reckons there’s more to be had from the compact SUV, offering a new “PowerXtra B40 600” performance package (for both the standard and coupé body styles) that hikes the eight-cylinder's peak outputs to 441 kW and 800 N.m. The result is a claimed 3,6-second sprint to three figures (an improvement of two-tenths) and a new limited top speed of 300 km/h.

In addition to the implementation of this plug-and-play auxiliary control module, Brabus has also ditched the standard exhaust system in favour of its own stainless exhaust arrangement, complete with flaps allowing finer control of the exhaust note.

What else has Brabus thrown at the GLC63 S? Well, a number of naked-carbon body elements have been added in a bid to further enhance aerodynamics, along with tailor-made alloys measuring anywhere from 19 to 22 inches in diameter.

Then there’s some bespoke tuning of the air suspension system to allow a ride height some 30 mm lower than standard. The firm furthermore says it offers a host of options for customising the interior.
