2021 Ford Mustang GT Performance and Engine

The 5.0-Liter Coyote V8

Under the hood sits Ford's legendary 5.0-liter Coyote V8, producing 450 horsepower and 410 lb-ft of torque in stock form. This engine is widely regarded as one of the best naturally aspirated V8s in the modern automotive world — responsive, tuneable, and sonically satisfying in ways that turbocharged engines simply can't match.

10-Speed Automatic Transmission with SelectShift

Paired to that V8 is Ford's 10-speed automatic transmission featuring SelectShift, which lets drivers take manual control of gear changes via paddle shifters. The result is lightning-fast upshifts, confident downshifts, and a dual personality — docile in traffic, aggressive when you ask for it. Rear-wheel drive keeps the experience pure and engaging, putting all that V8 power through the back wheels exactly the way a Mustang should.

Ford Mustang GT Features and Interior

The 2021 Mustang GT Coupe comes loaded with a sport-tuned suspension, Brembo-available braking hardware, and a driver-focused cockpit designed to keep you connected to the road. Inside, expect Ford's SYNC infotainment system, an available 12-inch all-digital instrument cluster with customizable driving modes, dual-zone climate control, and premium audio options. The GT trim also includes selectable drive modes — Normal, Sport, Track, Drag Strip, and Snow/Wet — giving drivers real-world versatility across San Bernardino County's varied terrain.

Ford Mustang GT Reliability and Ownership

The 5.0-liter Coyote V8 has earned a rock-solid reputation for durability across multiple Mustang generations. Owners consistently report 100,000-plus miles with minimal issues when basic maintenance is followed — oil changes, spark plugs, and the occasional coolant flush are the routine items to stay on top of. The 10-speed automatic has matured significantly over its production life, and the 2021 model year represents a refined, well-sorted version of this transmission.

The Mustang GT's parts availability is excellent, and the enthusiast community is one of the most active in American car culture, meaning aftermarket support, DIY resources, and independent service options are plentiful throughout the Inland Empire. At just under 75,000 miles, this GT still has plenty of road ahead of it.

Always review service history and look for signs of regular oil changes as the key indicator of long-term engine health.
