Wilhelm Kuün

Welcome to Kuün Motorsport.

I’m Wilhelm Kuün, an engineer and lifelong automotive enthusiast with a passion for understanding how things work – and finding ways to make them work better.

I grew up around cars, helping my father with everything from servicing and maintenance to performance upgrades and the occasional buying and selling of cars. That early fascination never disappeared. Instead, it developed into an engineering mindset and an obsession with precision, quality and performance.

Kuün Motorsport is where those worlds come together.

The objective

The objective is not simply to fit performance parts. It is to take an already exceptional performance car and transform it into something genuinely special.

Every project begins by defining what we want the car to achieve. We then engineer the complete package around that objective – engine performance, suspension, brakes, wheels and tyres, aerodynamics, interior and exterior design – with every component selected to work as part of the whole.

  • Turbocharged engine with polished intake piping and braided hoses
    01 Engine performance
  • Red six-piston brake caliper behind a drilled carbon-ceramic disc
    02 Brakes
  • Carbon-fibre rear wing on swan-neck mounts
    03 Aerodynamics

The complete package

  • Engine performance
  • Suspension
  • Brakes
  • Wheels and tyres
  • Aerodynamics
  • Interior and exterior design

And then we test it.

The process

On this channel, you’ll follow the entire process: engineering, fabrication, installation, setup, diagnostics, problem-solving, product testing, dyno development and, ultimately, track testing.

First project

Audi TT RS

The Audi TT RS is where the Kuün Motorsport story begins. It is our first complete development project and our test platform for building a road-legal car capable of competing in modified road-car classes in time attack and hillclimb events.

  • Road-legal
  • Time attack
  • Hillclimb

From there, the vision is much bigger.

Platforms

Kuün Motorsport will specialise in bespoke project cars, primarily based on Audi, Porsche, Mercedes-AMG and Volkswagen performance platforms, with each vehicle individually engineered around its owner and purpose.

  • Audi
  • Porsche
  • Mercedes-AMG
  • Volkswagen

No shortcuts. No modifications simply for the sake of modification.

Just exceptional cars, thoughtfully engineered.
