29 MPG combined is a respectable figure for the 2018 Mazda CX-5 2WD with the 2.2L diesel engine, a blend of efficiency and driving enjoyment that attracts a specific crossover buyer. This isn’t hybrid-level fuel efficiency, but it delivers solid numbers for a vehicle prioritizing responsive handling and a premium feel, something many find worthwhile given the CX-5’s other features.

City and highway performance

The EPA estimates the 2018 CX-5 diesel achieves 28 MPG in the city and 31 MPG on the highway, reflecting the engine’s tuning for both low-end torque and sustained cruising efficiency. The city MPG showcases the engine’s responsiveness in stop-and-go traffic, and the highway MPG highlights its ability to maintain efficient speeds on longer journeys. The smooth-shifting six-speed automatic transmission (S6) complements the engine’s performance, further optimizing fuel consumption across varying driving conditions. Drivers who spend more time on open roads will likely see results closer to the highway estimate, while those primarily navigating urban environments may find their average aligns more closely with the city figure.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Mazda CX-5 2WD diesel at precisely $1,900. This figure is based on driving 15,000 miles per year, assuming national average fuel prices. It’s important to understand this is an estimate, your actual fuel costs may vary depending on your driving habits, the type of fuel you use (although diesel is required, price fluctuations can impact the final cost), and where you live, as fuel prices can differ significantly across states. However, $1,900 provides a useful baseline for budgeting and comparing the CX-5’s running costs to other vehicles in its segment.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can differ. The 2018 CX-5 diesel is known for delivering relatively consistent fuel economy in everyday driving. Owners frequently report numbers close to the EPA’s estimates, particularly on longer trips where the diesel engine’s inherent efficiency shines. Aggressive driving habits, heavy cargo loads, and frequent short trips can negatively impact fuel economy. Conversely, prioritizing smooth acceleration, maintaining consistent speeds, and proper tire inflation can help drivers achieve or even exceed the EPA’s estimates. It’s all about understanding the vehicle’s characteristics and adapting driving habits accordingly.

How it compares

In the crowded compact SUV segment, the 2018 Mazda CX-5 diesel’s fuel economy stacks up interestingly against competitors. The front-wheel drive Honda CR-V, for example, with its 1.5L turbo engine, achieves an EPA-estimated 30 MPG combined. The Toyota RAV4, in its non-hybrid form, gets around 26 MPG combined. While the CR-V offers slightly better numbers, the CX-5 appeals to buyers prioritizing a more engaging driving experience. The diesel engine delivers ample torque combined with Mazda’s renowned chassis tuning, creating a vehicle that involves the driver in a way many rivals don’t. Knowing that all Mazda fuel economy data shows a commitment to efficiency, CX-5 buyers often see the slightly lower MPG as a trade-off worth making, they appreciate the vehicle’s premium interior and athletic handling in addition to decent fuel economy. Comparing the CX 5 MPG across all years proves the diesel variant continues to be one of the most efficient trim levels.

Tips to maximize efficiency

The Mazda CX-5 diesel responds well to mindful driving habits. Avoid aggressive acceleration and braking, as these actions consume significantly more fuel. Gradual acceleration allows the engine to operate more efficiently, and anticipating traffic flow can minimize the need for hard braking.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which significantly reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side door.

Reduce unnecessary weight. Carrying excessive cargo in your CX-5 can negatively impact fuel economy. Remove any items you don’t need to lighten the load and improve efficiency. Consider removing roof racks when not needed to reduce aerodynamic drag.

Plan your trips strategically. Combining errands into a single trip can help you avoid multiple cold starts, which consume more fuel. Also, consider mapping out routes that minimize stop-and-go traffic, as consistent speeds are generally more fuel-efficient.

Use cruise control on the highway. Maintaining a consistent speed using cruise control can optimize fuel economy on longer trips. This helps to prevent unnecessary acceleration and fluctuations in speed, further optimizing the diesel engine’s efficiency.
