Note: Carlsson is traditionally a Mercedes-Benz tuning specialist. Since Citroën and Mercedes do not officially collaborate, this post explores the hypothetical "what if" scenario, aftermarket customization, or a misinterpretation of branding (e.g., Carlsson wheels on a C5). When you hear "Carlsson," you think of low-slung, brutish Mercedes-Benz coupes and convertibles. When you hear "Citroën C5," you think of a comfortable, hydro-pneumatic French cruiser for long motorway hauls.

But what happens if you cross German tuning pedigree with French suspension magic? You get the car that never was—but absolutely should have been:

If you have a C5 and a little imagination, a set of Carlsson wheels and a remap will get you 90% of the way there. And trust me—at your local cars & coffee, nobody else will have one.

The problem? It has the power of a sleeping grandparent. Most diesel C5s produce 130-200bhp. That’s fine for cruising, but boring for everything else.

Let’s break down why this hypothetical build is a masterpiece waiting to happen, and how you can create your own "Carlsson-style" C5 today. The Citroën C5 (especially the phase 2 models from 2008-2017) is a hidden gem. It features Hydractive III or IV suspension —a self-leveling, pillow-soft system that swallows potholes like they don’t exist.
