This 650kW Ford Mustang is ready to rock
Ford specialist RTR has unveiled its latest take on the Mustang, and the tough pony car is set to come to Australia.
Founded in 2009, RTR - or Ready to Rock - has become one of the top third-party tuners of the Ford Mustang, and its latest creation is the wildest yet.
Dubbed simply the Mustang RTR Spec 5 and based on the current S650-generation Mustang GT, the brand claims it’s “built to OEM+ standards that meet or exceed Ford’s own benchmarks”.
Like previous RTR vehicles, its bodykit is striking, adopting a huge front lip, extended wheel-arches, side skirts, a ducktail spoiler and tweaked rear bumper, all influenced by the company’s Formula Drift cars.
Slotted under the wider guards are a set of 20-inch RTR wheels, shod in fat Michelin Pilot Sport 4S tyres (305mm wide at the front, 315mm at the back), while it also sits lower thanks to a bespoke adjustable coilover suspension system.
RTR offers nine standard, nine premium and two colour-shift paint finishes, as well as a paint-to-sample service. All examples come with the Spec 5-exclusive graphics package.
The interior gets a numbered plaque, an RTR gear knob, RTR-specific leather upholstery for the Recaro seats and floor mats, while buyers can opt to have a racing harness fitted for an extra US$1199 (A$1835), something they’ll need if taking this beefed-up muscle car to the track.
Under the bonnet the 5.0-litre V8 engine has gained a 3.0-litre Whipple supercharger and intercooler, boosting outputs from 358kW and 567Nm to a tyre-tearing 650kW and 895Nm.
That’s even more than the 634kW Dark Horse-based Shelby Super Snake R (which uses the same supercharger) and the 608kW 5.2-litre supercharged Mustang GTD, making the RTR Spec 5 the most powerful Mustang with a warranty.
Like the Super Snake R, the Spec 5 relies on a Borla cat-back exhaust system to shout louder, tweaked specifically for RTR.
Just 50 examples of the RTR Spec 5 will be built for the 2026 model year, each priced in its home market from US$159,999 (A$245,000).
Melbourne-based Mustang Motorsport has confirmed it’ll bring the RTR Spec 5 to Australia, however prices are yet to be announced.
For context, the Spec 3 kit is priced from $46,500, not including the price of the Mustang GT donor car.
