Mazda CX-5 MPG: Complete Gas Mileage Guide

Fuel economy is usually the first spec a compact-SUV shopper looks up, and the Mazda CX-5 answers that question in an unusually tidy way. One engine, one drivetrain, and one set of numbers; no decoder ring required and no complex trim chart to cross-reference before calculating what your weekly gas bill will cost.

Key Fuel Economy Specs

• EPA Rating: 24 miles per gallon (MPG) city / 30 MPG highway / 26 MPG combined
• Engine: Skyactiv-G 2.5-liter 4-cylinder (187 horsepower / 186 pound-feet of torque)
• Drivetrain: i-Activ All-Wheel Drive (AWD) standard across all trims
• Fuel System: Regular unleaded, 15.3-gallon fuel tank

One Engine, Zero Trim-Level Guesswork

Every variant of this crossover runs the exact same Skyactiv-G 2.5-liter four-cylinder engine paired with a six-speed automatic and standard i-Activ AWD. That means efficiency isn’t a variable as you climb through the trim lineup.

The entry 2.5 S trim posts identical EPA figures to the top-tier 2.5 S Premium Plus: 24 city, 30 highway, and 26 combined. Shop for the comfortable leather seats, upscale audio, or larger center display without worrying that upgraded wheels or added technological features will quietly degrade your fuel economy.

Real-World Range and Full-Tank Math

The 15.3-gallon fuel tank delivers practical long-distance capability. At 30 MPG on the highway, expect roughly 450 miles between fill-ups, plenty to cover a full weekend road trip without constantly scouting highway exits for a gas station.

Mixed city and highway driving lands closer to 400 miles per tank. Notably, Car and Driver’s independent instrumented test matched the EPA city figure at exactly 24 MPG, demonstrating a rare degree of real-world alignment.

Standard AWD and Regular Fuel Value

Two critical details stand out against segment competitors. First, the CX-5 runs entirely on regular unleaded gasoline, ensuring actual savings at every pump without requiring expensive 93-octane fuel. Second, all-wheel drive comes standard rather than as an optional add-on that quietly taxes your mileage.

Many rivals publish headline figures in front-wheel-drive form, shaving 1 to 2 MPG off once AWD is selected; the CX-5’s 26 MPG combined rating already accounts for AWD. Looking ahead, an upcoming hybrid variant confirmed for 2027 will raise the efficiency ceiling further.

Everyday Habits That Shift Mileage

• Tire Pressure: Check monthly; underinflated tires silently eat away at fuel mileage.
• Mi-Drive Modes: Normal mode handles daily driving efficiently, while Sport mode sharpens throttle response at the cost of fuel.
• Roof Gear: Remove crossbars and cargo boxes when not in use to reduce aerodynamic drag.
• Warm-Up Idling: Modern engines don’t require prolonged idling before setting off, even in cold weather.
