14 MPG combined. Let’s be honest. If you’re worried about that number while contemplating the purchase of a 2022 Ford Shelby GT500 Mustang, you’re missing the point entirely. This isn’t a car designed for hypermiling; it’s a purpose-built weapon engineered to dominate at the track and deliver a visceral driving experience unmatched by almost anything else on the road. Fuel economy is an afterthought for the kind of buyer who prioritizes 760 horsepower and earth-shattering acceleration.

City and highway performance

The official EPA ratings for the GT500 reveal the breakdown: 12 MPG in the city and 18 MPG on the highway. These numbers reflect the engine’s inherent thirst when subjected to lower speeds, frequent stops, and the temptation to unleash a fraction of its power. The relatively low highway figure underscores the aerodynamic challenges of a car designed for downforce, not drag reduction. While 18 MPG might be achievable on a long, gentle cruise, consistent high-speed runs will invariably result in lower numbers. The seven-speed dual-clutch automatic transmission, while contributing to lightning-fast shifts, doesn’t dramatically improve efficiency and is instead prioritized for performance.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Shelby GT500 is a sobering $4,150. This figure is calculated based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. Consider this a baseline. Owners who frequently tap into the GT500’s performance capabilities, spend more time at the track, or live in areas with higher fuel costs can expect to exceed this amount, substantially. The amount reflects the GT500’s performance demands and is factored into the cost of ownership for those seeking its unique capabilities.

Real-world expectations

Forget the EPA numbers. Real-world fuel economy in a GT500 hinges entirely on driving style. Treat the car with restraint, and you *might* see figures close to the EPA estimates. However, this is highly unlikely. The supercharged V8 begs to be unleashed, and resisting that urge is difficult. Most owners will experience mileage closer to the single digits during spirited driving, especially on the track. Accepting this reality is part of the ownership experience. Factors like ambient temperature, tire pressures, and even the blend of gasoline can also influence fuel consumption.

How it compares

Compared to its competitors, the GT500’s fuel economy is predictably low. The Chevrolet Camaro ZL1, with its 650-horsepower supercharged V8, achieves around 16 MPG combined. The Dodge Challenger Hellcat Redeye, producing upwards of 797 horsepower, posts similar numbers to the GT500. The Porsche 911 Turbo S, while significantly more expensive and offering superior handling and a more refined driving experience, manages around 17 MPG combined, showcasing the differences between a high-performance sports car and a track-focused muscle car. These comparisons are only relevant if fuel economy is on your priority list, a notion quickly dismissed by most supercharged-muscle-car buyers. When you are looking at SHELBY MPG across all years, the 2022 GT500’s fuel economy is consistent with its predecessors.

Tips to maximize efficiency

While squeezing the most miles out of a gallon might seem counterintuitive to the GT500’s purpose, some techniques can help. Avoid aggressive acceleration and braking. Smooth, gradual inputs will minimize the demand on the supercharger, resulting in slight fuel consumption gains. But the key word is slight.

Ensure your tires are properly inflated. Underinflated tires create increased rolling resistance, which reduces fuel economy. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure for optimal performance and economy. Consistent checks are recommended, even if you frequently spend time on the track.

Use the correct fuel octane rating. The GT500’s engine is designed to run on premium fuel. Using lower-octane fuel can lead to reduced performance and potentially damage the engine, negating any marginal cost savings at the pump. Stick to the manufacturer’s recommendation.

Limit idling time. Excessive idling wastes fuel, particularly with a large-displacement engine like the GT500’s. If you anticipate being stationary for more than a minute, consider turning off the engine. This is particularly relevant during cool-down periods after track sessions.

Track days are especially brutal. Adjust your expectations accordingly. All Ford fuel economy data, including the Shelby GT500, is collected during normal driving conditions, not high-RPM track simulations. Do not expect highway MPG when you are running on the track.
