KRB Audi S1 Silhouette

If you are a frequent visitor of Speedhunters.com, or any tuner blog or site, there is no way you never seen this car before.

It’s a one-off build by KRB-Trading of Norway for the “Extreme”-class race series, held as part of the Scandinavian Gatebil tuner/car culture festivals. A car built with basically no rules and limits. Somewhere between Unlimited Time Attack and “cure for polar night depression”. Over 1000 bhp at all four wheels. Big turbo lag, even bigger wings.

While it looks like an Audi S1 Evo 2 rally car on steroids, pretty much only the S2 cylinder head sports the four rings. This emulsification of Scandinavian performance and tuner culture further consists of a VW Transporter inline-5 2.5 litre TDI engine block, Comp Turbo CT 43 71/79 turbocharger, Sellholm MPG Rallycross transmission and front differential, KRB-custom Ford 9” rear differential, Porsche Cup tires, Volvo S80 front uprights on all four corners and a fully custom tubeframe chassis that may even have some sheeting left from a FWD ’85 Audi Coupé, among other things. All clad in a Quattro E2 Pikes Peak replica bodykit, modified to fit the tubeframe and extended wheelbase.

With this mod I tried replicating the car in as much detail as possible, and feasible, for Assetto Corsa. As the car was constantly being modified over the years it’s pretty much impossible to get everything 100% right. The cockpit for example is closer to the current form of the car (which now runs a twinturbo V8), while the engine and body are closer to the state of the car in 2013.

Suspension and cockpit are fully animated, plus visible aero settings too. Custom soundbank.

As with my Porsche, the car comes with 8 skins, two based on the real KRB, three based on classic Audi motosport liveries, one inspired by Karl Werner's Bergcup S2, one inspired by Darren McNamara's new DMAC S1 drift car, and a clean one. Skin template is included, let me know what you create with it.

Aero of the car has been simulated in OpenFoam, and makes the car pretty tricky to handle. See for yourself…
