The Engine

What Engine Makes the Mustang GT's Horsepower?

The Mustang GT uses Ford's 5.0L Ti-VCT V8, commonly known as the Coyote. Unlike a turbocharged or supercharged engine, the GT's V8 is naturally aspirated, which contributes to its immediate throttle response, linear power delivery and distinctive exhaust note.

Ford rates the standard 2026 Mustang GT at 480 horsepower at 7,150 rpm and 415 lb-ft of torque at 4,900 rpm when using 93-octane fuel.

When the car is equipped with the available Active Valve Performance Exhaust, Ford rates output at 486 horsepower at 7,250 rpm and 418 lb-ft of torque at 4,900 rpm.

Active Valve Performance Exhaust

Does the Active Exhaust Actually Add Horsepower?

Yes. On the 2026 Mustang GT, Ford's published figures show an increase from 480 horsepower and 415 lb-ft of torque to 486 horsepower and 418 lb-ft when equipped with the available Active Valve Performance Exhaust.

The system also changes the character of the car by allowing different exhaust sound settings. That makes it more than a cosmetic option for buyers who care about both output and the way the V8 sounds.

The six-horsepower increase is modest compared with the GT's overall output, but the exhaust system can still be an appealing option for buyers who want the strongest factory GT rating without moving to a Dark Horse.

Premium Fuel

Does the Mustang GT Need 93 Octane to Make Full Power?

Ford's published 480-horsepower, 486-horsepower, 415-lb-ft and 418-lb-ft ratings are measured using 93-octane fuel. That is important when comparing Mustang GT horsepower figures because the advertised maximum output is tied to premium fuel.

Owners should always follow the fuel recommendations in the owner's manual for their specific Mustang and driving conditions.

GT vs Dark Horse

Is 500 HP in the Dark Horse a Big Step Up?

The Dark Horse produces 500 horsepower, which is 20 horsepower more than a standard Mustang GT and 14 horsepower more than a GT equipped with the available Active Valve Performance Exhaust.

The bigger distinction is that the Dark Horse combines its extra power with additional cooling, standard MagneRide damping, larger Brembo brakes and more track-focused chassis tuning.

If your main goal is simply to own a fast naturally aspirated V8 Mustang for the street, the GT's 480 to 486 horsepower already delivers serious performance. If you want the more complete factory track package, the Dark Horse has more than just a horsepower advantage.
