The 2021 Ford Mustang Mach 1 5.0L gets 18 MPG combined, defining it as a performance-focused machine that prioritizes raw driving thrills over fuel efficiency. Buyers seeking the ultimate track-day Mustang that isn’t a Shelby will likely prioritize lap times and exhaust notes far above fuel costs. This isn’t a commuter car; it’s a statement.

City and highway performance

EPA estimates suggest the Mach 1 with the automatic transmission gets 15 MPG in the city and 23 MPG on the highway. The available Tremec 3160 six-speed manual transmission will likely yield slightly different numbers in real-world driving, usually at least 1 MPG lower combined. The city figure reflects stop-and-go traffic and aggressive launches from stoplights, something most Mach 1 owners will indulge in. The highway number is attainable, but only with a light foot; sustained high-speed cruising or frequent passing maneuvers will quickly drop that figure.

Annual fuel cost

The official EPA annual fuel cost for the 2021 Ford Mustang Mach 1 is $2,450. This estimation is based on driving 15,000 miles per year and using national average fuel prices. Of course, this number can fluctuate significantly depending on your driving habits, the type of fuel you use (premium is recommended), and regional fuel prices. Someone who only drives the Mach 1 on weekends or for track days will likely spend far less than $2,450 annually, while someone who uses it as a daily driver in a congested city could easily exceed that amount.

Real-world expectations

Real-world fuel economy for the Mach 1 is largely dictated by the driver’s right foot and less so the EPA estimates. Achieving 23 MPG on the highway is possible on a long, flat road at consistent speeds, but it’s not the typical experience. A more realistic expectation for mixed driving is around 16-19 MPG. Extended periods of hard acceleration, spirited backroad drives, or track usage will plummet the fuel economy into the low teens, or even single digits. Owners considering a Mach 1 should budget accordingly and factor in this expense when planning their automotive budget.

How it compares

Compared to other performance coupes, the Mach 1’s fuel economy is typical. The Chevrolet Camaro SS with the 6.2L V8 achieves around 19 MPG combined, while the Dodge Challenger R/T Scat Pack hovers around 18 MPG combined. Even the smaller four-cylinder turbo Mustangs often struggle to reach significantly better mileage in real-world, aggressive driving situations. A BMW M4, while offering a different driving experience, manages around 19 MPG combined. The Mach 1 buyer knowingly sacrifices fuel efficiency for the strong performance and distinctive character of the 5.0L V8. For a broader perspective, compare MUSTANG MPG across all years.

Tips to maximize efficiency

While fuel economy isn’t the primary concern for most Mach 1 drivers, there are still ways to improve it. Avoid aggressive acceleration and hard braking. The car’s performance encourages a heavy foot, but modulating the throttle can make a difference over time.

Ensure your tires are properly inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, negatively impacting fuel economy. Check your tire pressure regularly, particularly before long trips.

Minimize idling. Modern engines don’t require long warm-up periods, so avoid idling the engine unnecessarily. If you anticipate being stopped for an extended period, turn off the engine.

Use cruise control on long highway drives. Maintaining a consistent speed can improve fuel economy compared to constantly varying your speed with the throttle. However, avoid using cruise control in hilly areas, as the system may downshift frequently, negating any potential fuel savings.

Consider skipping the shorter gear ratios that lower acceleration times, but also use more fuel. The standard ratio is a good compromise, and it will help prevent that 5.0L V8 from revving so high at high speeds.
