As you may remember, a few days ago we introduced you to a rather special RENNtech Mercedes S63 AMG Coupe fitted with loopy wrap for the GoldRush rally. Now we’re visited by another version of that car boasting even more power and finished in a cool matte black.

Now this is just dopeness itself. Let’s just go over what we have here real quick so we can appreciate the ingredients: the car here is a big luxury Mercedes coupe; it’s finished in what’s quite possibly the coolest color in the world; and it’s tuned by one of the best names in the tuning business. I think I’m right in saying this RENNtech Mercedes S63 AMG Coupe is the best of its kind.

The first thing you’ll notice about this bad boy upon seeing it for the first time is that superb finish. But look closer and you’ll see it also has a carbon fiber decklid spoiler which we haven’t seen on any other S-Coupe and it’s complemented with black wheels and a revised diffuser housing two pairs of tailpipes.

Those pipes are connected to a custom exhaust system – featuring downpipes with 200 cell cats, sport mufflers with electronic valves – which is part of the power upgrade package for RENNtech Mercedes S63 AMG Coupe. The other part is an ECU upgrade. Together they produce 708 horsepower and 839 lb-ft of torque at the crank, but sadly when that power reaches the rear wheels it’s more like 588 whp and 697 lb-ft duo to drivetrain loss.
