Sunglasses on: Mansory has got its hands on the Mercedes G63

It was a question of when, and not if, Mansory would take the latest W465-generation Mercedes-Benz G63 and do some things to it. And sure enough, that time is now.

Two versions are available from the off: the ‘Grand Entrée’ and the ‘Gronos’. Only eight units are planned for each program, so this might be your only chance to ever see one. Sunglasses on, then.

We’ll get to the contrasting designs in a tick because the generic change for the two is… a big one. The 4.0-litre V8 has had a larger pair of turbos strapped on and linked to a new exhaust system. The result is 831bhp and 848lb ft - that’s 237 more for the former and 221 for the latter - and means 0-62mph is dispatched in four seconds flat. Spritely, for a cathedral.

On to the details and beginning with the Grand Entrée, there’s an entirely new body kit which includes new front/rear bumpers and splitters, side skirts and wheel arches, all conjoined as one big piece.

Mansory’s then given it a set of spotlights up top, 24in 10-spoke alloys from its totally normal Pugnator and a purposeful wing at the rear. This lot’s all been stitched together by a two-tone paint scheme which mostly consists of that strange part-carbon, part-blackboard vinyl seen on its GT2 car-like MC20.

The bright yellow Gronos’ body kit is similar to its opposite number, though the front fog lamps are horizontal as opposed to vertical, the roof light bar has two large rectangle bulbs instead and the rear wing consists of two independent attachments at either corner. No seriously, they will help with downforce.

Back on to the shared traits, there’s new soft-closing technology applied to the rear boot door hinges, which makes it easier to get in, after which you’ll be greeted by an interior that’s bespoke to you, since these Mansory conversions almost always come with a blank canvas for you to option up.

Said options here include embroidered logos, a leather sports steering wheel and quilted floor mats, with a model number woven in along the centre console to make you feel a bit more special.

There’s no fixed entry point for either the Gronos or Grand Entrée, but you will need at least £137,000 for a standard G63 to begin with. And maybe a set of sunnies if you're going for the Gronos.
