The gullwing doors swing upward, defying gravity and logic. It's a silhouette that stops you cold. If you grew up playing Gran Turismo 5 or Gran Turismo 6, you know exactly what I’m talking about. The Mercedes SLS AMG Gran Turismo edition—specifically that matte black "Stealth Model"—wasn't just a digital asset. It was a statement. It was the kind of car that made your friends pause the game just to look at the light reflecting off the long, aggressive hood.
Honestly, the SLS AMG is a weird beast in the real world, but in the Polyphony Digital universe? It became a legend.
The Digital DNA of the SLS AMG Gran Turismo
Kazunori Yamauchi is a perfectionist. Everyone knows this. When Polyphony Digital partnered with Mercedes-Benz for the launch of Gran Turismo 5 back in 2010, they didn't just want a car on the cover. They wanted the car to be the game. The SLS AMG was the first "clean sheet" car developed entirely by AMG, and its inclusion in the GT franchise felt like a passing of the torch from the old-school SLR McLaren to something more brutal, more German, and significantly more "GT."
You’ve probably seen the signature "Stealth Model" version. It wasn't just a paint job. This specific variant was part of the Collector’s Edition and the Signature Edition. It featured carbon fiber everywhere and a tuned version of the M159 engine. In the game’s physics engine, it felt heavier than the GT3 race cars but more planted than the standard road-going version. It was the middle ground. The sweet spot.
Why the Physics Actually Mattered
Driving the SLS in Gran Turismo wasn't easy. You couldn't just mash the throttle. The front-mid engine layout—that massive 6.2-liter V8 sitting way back behind the front axle—meant the car had a pivot point that felt different from almost anything else in your garage. If you were too aggressive on the rumble strips at Trial Mountain, the back end would step out with a violence that required genuine skill to catch.

It felt alive. It felt like it wanted to kill you, but in a fun way.
Real World vs. The Sim
Let’s get one thing straight: the "Gran Turismo" version of this car in the real world mostly refers to the SLS AMG GT trim that arrived around 2013. It wasn't just a marketing tie-in; it was a legitimate performance upgrade. Mercedes bumped the power to 583 horsepower. They re-tuned the AMG Ride Control suspension to be stiffer because, frankly, the original SLS was a bit of a grand tourer at heart.
- The transmission was the real hero.
- In the early cars, the dual-clutch was... okay.
- In the GT-spec (the one inspired by the sim racing feedback), the shifts became crisp. Instant.
- It felt like the digital version.
I remember reading an interview where the engineers admitted they looked at how players were interacting with the car's limits in the simulator to refine the "GT" badge for the actual road. That’s a rare moment of art imitating life imitating art.
The Stealth Model Obsession
The matte black finish. The carbon fiber accents. The "GT" logo on the rear. For a lot of us, the Stealth Model SLS was the first time we understood the concept of "exclusive DLC." You couldn't just buy it with in-game credits; you had to have the code. This created a weird digital hierarchy in the online lobbies of the early 2010s. If you showed up in a Stealth SLS, people knew you were a die-hard.

The performance specs were nuts for a "tuned" road car:
The 0-60 mph sprint happened in about 3.6 seconds. That’s fast even by today’s standards. The top speed was electronically limited to 197 mph, but in the game, if you messed with the gear ratios, you could see the high 200s on the Mulsanne Straight at Le Mans. It sounded like thunder. That deep, rhythmic AMG bark that sounds less like an engine and more like a demolition crew.
What Most People Get Wrong About the Handling
There’s a common myth that the SLS is a "boat." People say it’s too long and too heavy to be a real track car. Those people are wrong.
Basically, the SLS AMG Gran Turismo models utilize a transaxle layout. The engine is up front, but the transmission is in the back. This creates a 47/53 weight distribution. When you're diving into a corner at Suzuka, the car rotates remarkably well. The "nose-heavy" look is a visual lie. Once you understand that the weight is centered between the wheels, you start to drive it differently. You realize you can trail-brake deep into the apex, let the front bite, and then use that massive torque to power out.
It’s a thinking man’s muscle car.

The Collector’s Reality in 2026
If you’re looking to buy a real SLS AMG GT today, prepare to pay. The market for these has exploded. While the standard SLS is expensive, the GT-spec models and the final editions are reaching "investment grade" status. They were the last of the naturally aspirated V8 giants. No turbos. No hybrid assistance. Just displacement and drama.
In the world of Gran Turismo 7, the car remains a staple in the Hagerty Legendary Cars dealership. It pops up occasionally, and when it does, it’s a multi-million credit investment. But it's worth every bit of digital currency.
Why It Still Matters
- It represents the peak of the Mercedes-Sony partnership.
- The M159 engine is arguably the greatest V8 ever put in a production car.
- The Gullwing doors are cool. Period.
The SLS didn't have to be good. It could have been a styling exercise. But because Polyphony Digital pushed for such high fidelity, and because Mercedes wanted to prove they could build a supercar without McLaren’s help, we ended up with a masterpiece. It's a car that bridges the gap between the analog era of driving and the digital era of simulation.
How to Master the SLS in Modern Sim Racing
If you’re firing up Gran Turismo 7 or even Assetto Corsa today to drive the SLS, don't treat it like a modern GT3 car. It doesn't have the same level of aero-dependence. It relies on mechanical grip.
First, stiffen the rear rebound. This helps settle the car after high-speed transitions. Second, don't go full-stiff on the anti-roll bars; you need a little bit of weight transfer to help the front tires find grip. Finally, manage your heat. The big V8 gets hot, and in endurance races, you’ll feel the power dip if you aren't careful with your cooling ducts.
Actionable Steps for Enthusiasts
If you're a fan of the SLS AMG Gran Turismo legacy, start by exploring the used car markets in Gran Turismo 7—the 2013 GT model is the one you want for the most authentic experience. For those looking at the real world, track the auctions on "Bring a Trailer" or "RM Sotheby’s" specifically for the 2013-2015 model years to see the price delta between the base and the GT trims. Finally, if you're a photographer, the SLS's proportions make it one of the best subjects for the Scapes mode in GT; try shooting it at the Nürburgring at sunset to see how the light catches the distinctive roofline. This car isn't just a piece of history; it's a blueprint for what happens when a car manufacturer and a game developer actually listen to each other.
