Engine and Performance: Supercharged 5.0 V8 with Over 870 Horsepower
The heart of the Mustang RTR Spec 5 is the Ford Performance-supplied supercharged 5.0-liter V8 engine, generating an impressive power output exceeding 870 HP and 660 lb-ft of torque. This places it ahead of the 2025 Mustang GTD, which has 815 horsepower, but with a more competitive price, making the Spec 5 an attractive option for enthusiasts seeking premium performance without the exorbitant cost of traditional supercars.
Besides robust power, the Spec 5 offers mechanical versatility by allowing the choice between a 10-speed automatic transmission with quick shifts and a manual option, or a 6-speed manual gearbox for purists who value full control and direct connection with the machine.
Design and Customization: Widebody and Carbon Fiber for Performance and Style
Visually, the Mustang RTR Spec 5 impresses with its expanded widebody chassis, built almost entirely from exposed carbon fiber, reducing weight and increasing structural rigidity. This combination results in an aggressive and functional design, where the spoiler, fenders, and splitter have been optimized for greater downforce and stability at high speeds — key characteristics for both track and street use.
The multi-level adjustable suspension allows customizations that balance urban comfort and aggressive grip on circuits, making the Spec 5 a versatile machine for those who demand performance without sacrificing daily drivability. Production is limited to 50 units annually, highlighting its exclusivity and appeal to collectors.
Driving and Fun: E-Dynamic Technology for Drift and Advanced Control
Setting itself apart from muscle cars focused exclusively on lap times, the Spec 5 embodies the philosophy of its creator Vaughn Gittin Jr., who prioritizes driving enjoyment. With the e-drift brake system, the vehicle allows the driver to initiate controlled drifts with ease, broadening the experience for enthusiasts who enjoy sportiness and dynamic maneuvers.
This technology, combined with the hefty torque of the supercharged V8, offers an exciting drive on both winding roads and dedicated tracks. When compared to other cars in its range, such as the 2025 Mustang GTD, the Spec 5 stands out for its combination of power, cost-effectiveness, and exclusivity.
Technical Versatility and Premium Components
The Mustang RTR Spec 5 is equipped with Michelin Pilot Sport 4S tires, highly renowned for their superior grip in varied conditions, mounted on 20-inch wheels with widths of 305 mm in the front and 315 mm at the rear, optimizing stability and control in corners. The brakes are high-performance Brembo units, ensuring consistent and safe stopping power, even under intense use.
The fully adjustable suspension architecture allows both professional and amateur drivers to tune the car for various uses — from comfortable daily driving to track racing.

Exclusivity Within Your Reach
With a starting price of US$ 159,999, the Mustang RTR Spec 5 positions itself as a high-level muscle car option, accessible compared to iconic competitors like some Corvette versions. Its limited production run and the technical expertise of RTR Vehicles confer prestige and added value for owners, who enjoy a rare model with superior performance and sophisticated design.
The Mustang RTR Spec 5 Defines the Future of Muscle Cars
This release represents the perfect balance between American tradition and technological innovation, with a supercharged engine that pushes conventional limits, distinct transmission options, and a chassis designed to maximize performance and style. The Spec 5 reaffirms the importance of keeping up with trends in sports vehicles, especially with the ongoing evolution of SUV and electric segments, as exemplified by the 2026 Nissan Sentra, showcasing the transformation of the automotive market.
If power, exclusive design, and driving experience are your priorities, the Mustang RTR Spec 5 2026 is undoubtedly one of the best choices in the muscle car segment for the coming years.
