Brabus is seemingly never satisfied when it comes to horsepower. Even when it's working with the obscene powerhouses from AMG, Brabus just can't leave well enough alone. For years, the German tuner has been taking high-performance Mercedes-Benz cars well beyond their original factory specs. Now, Brabus has turned its sights to the Mercedes-AMG GT S, which it has endowed with 591 hp.

Just as we saw on the Mercedes-AMG C63 S, Brabus starts by retuning the AMG GT S's 4.0-liter twin-turbo engine. Output rises from the stock ratings of 503 hp and 479 lb-ft of torque to a claimed 591 hp and 553 lb-ft. That's enough, Brabus says, to slice the GT's 0-to-62-mph sprint to just 3.6 seconds, while also raising the car's top speed to 201 mph. Despite all that extra performance, Brabus says its tuned version of the Mercedes-AMG GT S engine still meets European emission regulations.

To help drivers further appreciate the performance of their tuned Mercedes-AMG GT S, Brabus also installs a new titanium quad-exhaust that is said to be 40 percent lighter than the stock system. As in the C63, Brabus offers the exhaust with a "coming home" button that reduces the car's exhaust volume so as not to annoy your neighbors.

Other enhancements include a new front fascia with a splitter and LED running lights, a new diffuser and rear spoiler, and new Brabus-designed wheels measuring 20 inches in front and 21 inches in back. Brabus suspension springs also lower the Mercedes-AMG GT S by 0.6 inch. Inside, look for new aluminum shift paddles, illuminated doorsill plates, and various leather and Alcantara trim pieces.

Although pricing has yet to be announced, getting a Brabus-tuned Mercedes-AMG GT S requires deep pockets: The standard car alone starts at a cool $129,925 in the U.S.
