The Mustang has always been about freedom and fun, but the new 2026 Mustang RTR Spec 5 takes that spirit and cranks it to eleven. Vaughn Gittin Jr. and the crew at RTR Vehicles have built something that doesn’t just look the part; it redefines what a modern muscle car can be.
More Muscle Than the GTD
Let’s start with the headline number: 870-plus horsepower. That’s coming from a supercharged 5.0-liter V8 under the hood, and yes, it’s more than the Mustang GTD makes. Suddenly, the Spec 5 is the most powerful pony you can buy without venturing into hypercar territory.
What makes it even more compelling is the price. At $159,999, it’s not cheap, but when you stack it against other cars in this league, it feels almost like a bargain.
Looks That Mean Business
The first thing you notice is the stance. The Spec 5 wears a widebody kit that’s mostly carbon fiber, so it’s lighter and slipperier through the air. It’s aggressive, sure, but it’s not cartoonish; it’s purposeful. Sitting on 20-inch wheels wrapped in Michelin Pilot Sport 4S tires, it looks like it could shred a track day, then cruise home without breaking a sweat.
Built to Be Driven
RTR didn’t just add power and call it done. They reworked the suspension so you can dial it in for road or track, depending on the day. The Brembo brakes are massive and confidence-inspiring, ready to haul the car down from triple-digit speeds again and again.
This isn’t a car that overwhelms you; it’s a car that works with you.
Drift DNA Inside
Vaughn Gittin Jr.’s fingerprints are all over this build. Known for his drifting prowess, he insisted on including an electronic drift brake. It sounds like a gimmick until you try it—suddenly the car’s not just fast, it’s playful. That’s what sets the Spec 5 apart: it isn’t afraid to have fun.
Rare by Design
Exclusivity adds to the appeal. RTR will only build 50 of these each year, making ownership a bit like joining a secret club. With customization options for paint and wheels, no two Spec 5s need to look the same.
A Mustang for Drivers
Here’s the thing: the Spec 5 isn’t about stats on paper, even though the numbers are wild. It’s about what happens when you fire it up, hear that V8 roar, and know the car beneath you was designed by people who genuinely love driving.
For decades, the Mustang has been the people’s performance car. The 2026 RTR Spec 5 proves it still is—only now it’s louder, sharper, and more willing to misbehave in all the right ways.
