The new Mustang Shelby GT500 has hit the dyno for the first time, and the results are very impressive.
With its supercharged 5.2-liter aluminum alloy V8 producing a monstrous 760 horsepower and 625 lb-ft of torque, the 2020 Ford Mustang Shelby GT500 is the most powerful street-legal car Ford has ever made. With this setup, the new GT500 will hit 0-62 mph in around 3.5 seconds, do the quarter-mile in less than 11 seconds, and hit a limited top speed of 180 mph. That's supercar levels of performance.
And yet the new GT500 could be even more powerful than Ford claims. To find out how much wheel horsepower it develops, YouTube channel Speed Phenom hooked their Shelby GT500 up to a dyno for the first time.
You may want to turn your speakers up because the ear-splitting noise this car makes is glorious. The YouTuber even says how his "ears felt like they were going to burst." The results were very impressive and suggest that Ford could be underrating the 2020 Shelby GT500's power by a significant margin.
Speed Phenom found that the 2020 Shelby GT500 produced 705 horsepower at the wheels. Factoring in a 15 percent parasitic driveline power loss, a 760-hp Shelby GT500 would develop around 650 hp at the wheels. This dyno result suggests the Shelby could produce as much as 825 horsepower, which is 65 more hp than Ford claims.
Of course, we can't verify the accuracy of the results. Let's not forget that MotorTrend's dyno test of the 2020 Chevrolet Corvette Stingray was found to be inaccurate after an investigation. Nevertheless, we wouldn't be surprised if Ford is underrating the GT500.
Ford recently confirmed to us that the GT500's Predator engine has a lot of tuning potential and that Shelby American is planning to extract more power. Shelby American will likely sell packages to make customer GT500s even faster than the standard car, with tuned versions potentially offering "at least 1,000 horsepower." Hennessey is also selling 1,200-hp variants of the new Shelby GT500.
