Detailed Comparison: 2017 vs 2018 Mazda CX-5

Powertrain and Performance Enhancements

The 2018 CX-5 retained the same 2.5-liter SKYACTIV-G four-cylinder engine producing 187 horsepower and 186 lb-ft of torque, but added an important new technology: cylinder deactivation. This system automatically shuts down two cylinders during light-load driving conditions (such as highway cruising) to improve fuel efficiency without compromising performance when needed.

While official EPA estimates for the 2018 model showed only modest improvements (about 1 mpg across all measurements), real-world driving often showed more significant gains, especially for highway commuters. The system worked seamlessly, with most drivers unable to detect when cylinder deactivation was active.

Safety Technology Democratization

Perhaps the most significant change for 2018 was Mazda's decision to make its i-ActivSense safety suite available across all trim levels:

This strategic move positioned the CX-5 as one of the safest vehicles in its class, competing directly with luxury brands that typically charged premium prices for these advanced safety features.

Trim Level Breakdown: What Changed for 2018

Fuel Efficiency: Real-World Improvements

While the EPA ratings showed modest gains (24/31/27 mpg city/highway/combined for FWD models, up about 1 mpg across the board), many owners reported more significant improvements in real-world driving:

• Highway mileage: Multiple owner reports indicated 33-35 mpg was achievable in steady cruising
• City driving: The cylinder deactivation system proved most effective in suburban driving (25-27 mpg observed)
• AWD impact: The all-wheel drive system's penalty decreased slightly to just 1 mpg difference in combined rating

These improvements helped the CX-5 maintain its position as one of the most fuel-efficient non-hybrid compact SUVs, especially impressive given its sporty driving dynamics.

Buying Advice: 2017 vs 2018 CX-5

The decision between model years depends largely on your budget and desired features:

Consider the 2017 CX-5 If:

• You're shopping for a Grand Touring model and can find significant savings
• Advanced safety features aren't a priority for you
• You prefer the slightly firmer suspension tuning of the 2017 model

The 2018 CX-5 Makes More Sense If:

• You want the latest safety technology, especially on lower trims
• Fuel efficiency is a top priority (cylinder deactivation helps)
• You prefer the slightly revised interior materials and features
• The modest price increase fits within your budget

For most buyers, the 2018 model's safety tech improvements justify the small price premium, especially when considering potential insurance discounts and resale value.

What Remained Unchanged

While the 2018 updates were meaningful, Mazda kept many of the CX-5's best qualities intact:

• Chassis dynamics: The precise steering and balanced handling that made the CX-5 stand out
• Interior space: Identical passenger and cargo dimensions (59.6 cu.ft max cargo space)
• Infotainment system: The same Mazda Connect interface with rotary controller
• Exterior styling: Minor tweaks to grille and trim pieces, but overall design unchanged

Competitive Landscape

The 2018 updates helped the CX-5 compete more effectively against key rivals:

Ownership Experience and Reliability

Both 2017 and 2018 CX-5 models have demonstrated excellent reliability, with few significant issues reported. The 2018's additional technology features proved robust in long-term testing:

--FORTH CAR LIST HERE--

• J.D. Power Ratings: 4.5/5 for predicted reliability (2018 model)
• Common issues: Minor infotainment glitches, occasional brake squeal
• Maintenance costs: Below average for the class according to repairpal.com
• Resale value: Consistently among the best in class, with 2018 models holding slightly better value

The Verdict: Which Model Year Should You Choose?

After examining all factors, our recommendation is clear:

For most buyers, the 2018 CX-5 represents the better value due to its expanded standard safety features and improved fuel efficiency. The modest price increase is easily justified by the additional technology and refinements.

However, if you find a well-equipped 2017 Grand Touring at a significant discount (at least $2,000 less than a comparable 2018), it remains an excellent choice, especially if advanced safety features aren't your top priority.

Ultimately, both model years represent smart choices in the competitive compact SUV segment, offering a rare combination of driving enjoyment, premium feel, and practical utility that continues to set the CX-5 apart from its rivals.
