The 2025 Ford Mustang GTD is the most powerful Ford ever, but it's no lightweight mid-engine supercar like either generation of Ford GT. We drag race (and roll-race) the new GTD against a 2005 Ford GT (Gen 1) and a 2020 Ford GT (Gen 2) to determine which is the quickest accelerating Ford of all time.

The GTD is a comprehensive upgrade from the "regular" Mustang, meant for serious lap time performance. However, its rear-mounted transaxle and enormous rear tires also help in putting its insane 815 hp to the ground — and that means it could out-accelerate Ford's two recent mid-engine supercars.
The Gen-1 Ford GT (2005-2006) used a supercharged 5.4-liter V-8 and pumped out 550 hp. However, Ford offered a Performance Upgrade kit that bumped output up to about 650 hp using a smaller supercharger pulley, high-flow injectors, a bigger throttle body, and updated engine programming.
That puts the 2005 GT's power-to-weight ratio right on top of this 2020 Ford GT's.
The Gen-2 GT (2017-2022) switched to a turbocharged 3.5-liter EcoBoost V6 that made 647 hp. However, in 2020, the engine received updates and a revised 660-hp rating. With its 7-speed dual-clutch automatic, it beat the Gen 1 GT through the quarter-mile. But that was with a stock 2005 GT.
So the winner between those two is up in the air: we could find no tests of the Ford Performance Kit 2005 GT or the updated, more powerful 2020 GT! This is a world's first.
The 2025 Mustang GTD makes vastly more power than either supercar, but lacks mid-engine traction advantage and weighs some 1000 lb more than either of the GTs. So it's time to line them all up and see if the GTD can earn the title of the quickest-accelerating Ford ever produced.
We've done a standing-start drag race (complete with instrumented testing numbers) and then a roll-race to eliminate the automatic cars' Launch Control advantage – and see if the EcoBoost's turbo lag hurts it in real-world conditions.
