Forget everything you know about the Ford Mustang. From pony car to supercar, the GTD represents a new milestone for the blue oval brand. The most powerful Mustang ever made is engineered to intimidate supercars. The GTD is a track weapon and consequently comes with a carbon fiber widebody, advanced aerodynamics kit, and Brembo carbon ceramic brakes. Its first-of-its-kind suspension developed by Multimatic seamlessly adapts to road or track conditions, dynamically adjusting for peak performance.

The GT3 RS is also a highly capable machine in its own right. It is a track-focused evolution of the iconic 911 range. Its history stretches back to the 996 generation, with each iteration since pushing performance boundaries. Lightweight, carbon fiber-reinforced plastic(CFRP) hood, roof, aggressive aerodynamics, and a massive DRS-equipped keep weight down and generate downforce for exceptional handling.

Both Track-Bred Cars Offer Different Experiences In Performance

Both models sit at the top of the food chain for their respective model lineups and are track-derived machines that have been over-engineered to offer scorching performance. The GTD sheds pounds with several carbon fiber components which include fenders, hood, trunk, and more. You can also add an optional carbon fiber dashboard to complete the aggressive, lightweight package.

Porsche offers three versions of the 911 GT3s: the base model, a Touring variant with a subtler wing, and the king of the hill- the GT3 RS. The RS steals the show with its stripped-down aggression.

Ford Mustang GTD vs. Porsche 911 GT3 RS: Performance Numbers Compared

Under the hood, both cars possess distinct personalities. The Mustang GTD packs a monstrous 5.2L supercharged V8, that put out a 800 horsepower. The Porsche 911 GT3 RS counters with a naturally-aspirated 4.0L flat-six engine, generating a refined 518 horsepower. While the Mustang throws down raw muscle, the Porsche prioritizes a high-revving (9,000 RPM redline) experience that translates to a thrilling scream. The GTD’s estimated 0-60 mph time is still under wraps, but expect a sub-4.0-second time to rival the GT3 RS’s impressive 3.2-second dash to 60 mph. Both achieve lightning-fast gear changes: the GTD ships with an 8-speed dual-clutch and the GT3 RS with a 7-speed PDK dual-clutch.

When it comes to handling, the two cars offer diverging philosophies. The GTD focuses on raw power imparted through a lightweight carbon fiber driveshaft linked to an 8-speed rear transaxle, which helps it achieve a near 50/50 weight distribution for a thrilling, well-balanced driving experience. The GT3 RS meanwhile with its rear-engine layout has a 40/60 weight distribution and prioritizes razor-sharp agility and precision on the track, demanding a more nuanced driving style. The GTD’s secret weapon? A groundbreaking semi-active suspension.

It not only adjusts ride height by nearly 1.57 inches (40mm) in Track Mode for improved aerodynamics but also dynamically changes spring rates for optimal performance on both road and track. compared to the standard Mustang, the GTD’s exceptional handling, and stability come courtesy of the high-tech system, and a wider track. The GT3 RS counters with extensive use of lightweight materials like carbon fiber throughout and a massive DRS-equipped rear wing for superior downforce, allowing it to hug the corners at high speeds. The RS is capable of producing three times the downforce of a standard GT3 at 1,895 pounds at 177 mph. Ford hasn’t disclosed the downforce figures for the Mustang GTD, but a Multimatic spokesperson has confirmed to Car & Driver that it will be more that the 911 GT3 RS at 150 MPH.

In the end, the choice boils down to your driving style and price. Both cars feature active aerodynamics and are essentially track-cars that work on the road. The Mustang GTD is more expensive, but it has close to 300 more horsepower over the 911 GT3 RS and is a force to be reckoned. It’s perfect for drivers who crave a more visceral driving experience. The Porsche 911 GT3 RS meanwhile is a more refined track weapon with German sensibilities, demanding precision for the fastest lap times. It caters to drivers who value laser-sharp handling and a connected feel with the car. All that’s left now is to see how quickly the Mustang GTD can get around Nürburgring. Watch this space.
