The Ford Mustang Thread

Ford Mustang Handed Tyre-Shredding 650 kW by RTR

RTR has whipped the wraps off its most powerful Mustang-based project yet, the 2026 Mustang RTR Spec 5.

RTR has unveiled the Spec 5, the most powerful Mustang-based model this US tuning company has ever created. Only 50 examples will be built for 2026, each priced from $159 999, which, at the current Rand-Dollar exchange rate, translates to R2.7 million.

Based on the S650-generation Mustang GT Fastback, the Spec 5 employs the Blue Oval brand’s familiar Coyote powertrain. However, for the Spec 5, RTR has fitted the 5.0-litre naturally aspirated V8 with a 3.0-litre Stage 2 Whipple supercharger; lifting the peak power and torque outputs to a whopping 650 kW and 895 N.m. Two transmission options are available: 10-speed automatic and, for those who prefer rowing cogs themselves, a six-speed manual ‘box. The V8 soundtrack is provided by a Borla cat-back active exhaust system.

In addition to these revisions, RTR has also replaced the suspension setup; ditching the standard arrangement for its own Tactical Performance Suspension, which features 30-way adjustable coilovers, unique sway bars, and specially tuned dampers. Two-piece Brembo brake rotors provide stopping power and are sited behind 20-inch RTR Aero 5 Evo forged alloy wheels, wrapped in Michelin Pilot Sport 4S tyres.

 
Ford has revealed a new turbo Mustang for the yoof that’s built to drift

The first ever RTR-spec Mustang produced in-house by Ford is ready to go quite sideways

Young performance car enthusiasts of America, we bring you good tidings of performance brakes, active exhausts and anti-lag: meet the turbo Ford Mustang RTR built specifically to do big skids.

“This factory-built Mustang RTR is the answer for younger buyers seeking a performance-focused Mustang,” said RTR founder Vaughn Gittin Jr. Yep, the same multiple-drift-title-winning Vaughn Gittin Jr.

It’s the first RTR-spec Mustang built in-house by Ford and is absolutely not to be confused with the actual Mustang RTR Spec 5 we saw last month, which is basically a Mustang GTD for about half the price.

No, this one’s spun off the 2.3-litre turbocharged four-cylinder Mustang producing 315bhp/350lb ft, but can be optioned up to 350bhp/400lb ft via Ford Performance parts. It gets the 10-speed auto 'box sending those turbocharged horsies to the rear wheels.

 
Game on! Ford is working on a more-extreme Mustang GTD

Wild prototype snapped at the Nürburgring suggests Jim Farley wants his lap record back…

Ford CEO Jim Farley wasn’t joking when he said ‘game on’ back in August. That was his direct response to the Corvette team after their hybrid, 4WD, 1,250bhp ZRX1 blitzed the ‘Ring in 6m 49.3s, eclipsing the GTD’s personal best of 6m 52.1s… thus making the Chevy the new fastest American car to ever lap the Green Hell.

To rub salt in the wound, the ‘standard’ ZR1 - with its 1,064bhp, twin-turbo 5.5-litre V8 powering the rear wheels alone - wasn’t far behind, posting 6m 50.7. But like all great, but ultimately pointless battles between two great American institutions… Ford isn’t taking this one lying down.

Or so it would appear, according to these pictures of a suspiciously angry looking GTD taken at the Nürburgring earlier today. Clearly visible at the front are a set of downforce-boosting double dive planes. The front sills and splitter look more prominent too, while at the back it appears to be excreting its own exhausts – here’s hoping for something freer flowing and even fruitier sounding once this ugly mule becomes a tearaway ‘Stang.

Remarkable really that Ford has found any headway to boost power and downforce when the standard cars produces 815bhp and 664lb ft of torque from its dry-sumped 5.2-litre supercharged V8, and 885kg of downforce at 180mph. It shouldn’t be hard to find some weight to shave though, given it weighs a porky 1,930kg in its lightest guise.
