This Is PROOF That Not All Badass Supercars Are Italian

And that gullwing doors don't suck.

The Mercedes-Benz SLS AMG wasn’t as fast, good-looking, or insane as the supercars from Italy, but it had an ace up its sleeve—it was fun. When Mercedes-AMG introduced the GT and GT S, the SLS AMG became obsolete and was forgotten. With its glorious 6.2-liter V8, the SLS AMG Black Series was tuned to produce 622 hp and could get to 60 mph in 3.5 seconds. In its hardcore guise, the SLS AMG Black Series could demolish any track day and had an aggressive look that was missing from Italian supercars.

To show some love to the supercar, RENNtech has given the SLS AMG Black Series some performance updates and an even more aggressive appearance. The most important aspect about the tuning company’s upgrades includes the ECU tune and stainless steel long tube headers. With these simple modifications, the SLS AMG Black Series now makes roughly 658 hp. The supercar also gets a variety of exterior parts to give the German brute a look that makes other Italian supercars look pedestrian. The SLS AMG Black Series was already an insane supercar, but RENNtech’s version is even more menacing.
