The RS Q8 is the most expensive Audi Sport model and the most powerful SUV ever to feature the four-ring logo.

You’d think the stock Audi RS Q8 would be enough for most customers and yet some feel the unexplained urge to modify it. That’s where companies like Manhart Performance come in, with the German tuner offering what’s likely the wildest upgrade package for the high-performance SUV.

It’s called the Manhart RQ 900 and it takes the stock RS Q8 one step forward when it comes to performance, looks and soundtrack. First of all, the 4.0-liter twin-turbo V8 engine now delivers 900 PS (888 HP) and 1,080 Nm (796 lb-ft) of torque thanks to larger turbochargers, extensive modifications to the engine and transmission upgrades.

These are massive gains over the stock model’s 600 PS (591 HP) and 800 Nm (590 lb-ft) of torque. The upgrade should clearly contribute to superior performance but Manhart does not supply any specifications.

Moving on to the rest of the upgrades, Manhart will also fit a rear silencer in Germany or a complete exhaust system for countries that are not so strict with noise levels. The chassis is upgraded as well and now features a 30 mm (1.2 in) lower suspension. The RQ 900 rides on 23-inch Concave One aluminum rims, which can be had in matte black or gunmetal gray diamond, depending on the vehicle color.

Manhart has also developed a new carbon body kit consisting of a bonnet, front spoiler, side skirts, diffuser, and wheel arch extensions. These parts not only give the RQ 900 a more aggressive look, but also improve the SUV’s aerodynamics. Rounding out the exterior upgrades is a Manhart decal set in the color chosen by the customer.

For the interior, the tuner offers an improved leather package with golden or red accents. The German tuner will only built 10 units of the RQ 900 worldwide and each one will cost a whopping €280,000 (approximately $303,400).
