By all standards, the C7 generation Audi RS6 Avant was never a slouch. Its twin-turbo TFSi V8 engine made an outstanding power output in its class, and it was already almost a decade since it was introduced.

But some folks from Europe just couldn't get enough. With an RS6 Avant going through stage 4 aftermarket tuning and a bevy of engine upgrades, the stealthy estate here makes over 1,000 horses and hides underneath a satin black finish. Auditography gives us a quick look at the vehicle, along with the lot of upgrades it received.

According to the channel, this Audi RS6 Avant from the Netherlands received stage 2+ tuning with upgraded exhaust manifolds, wastegates, and throttle body – all from Turbosystem. It also received 4 bar map sensors from SRM and water-methanol injection stage 3 from Snow Performance, along with a Forge charge cooler with an upgraded CWA 100-3 intercooler pump, Dual low-pressure fuel pump with larger lines, and high-pressure fuel pumps from Autotech.

Even better, the owner, who goes by the name Dave (@black_rs_6 on Instagram), did the turning and mapping himself using the Dynospectrum tool. The result is an output of 1,200 bhp and 1,069 lb-ft of torque, but only when using 102 octane fuel.

This tuned RS6 Avant can sprint to 62 miles per hour in 2.57 seconds, with a top speed of 217 mph. A quarter-mile run was clocked at under 10 seconds.

The satin black finish here was a wrap, while the whole build was done by DGM Performance, a tuning company based in Belgium. The car comes with Dynamic ride control with a 3P air ride airlift plus a set of 22-inch Vossen gloss black HF-2 wheels.

The video above should show you how this powerful estate sounds. It was cut short, though, as the rear axle of the vehicle broke due to the tremendous amount of power it needed to handle.
