2026 Mazda SUV Fuel Economy Ranked: From 3.8 Le/100 km to 9.5 L/100 km

Fuel economy is one of those specs that looks simple on a sticker but gets more interesting the deeper you look. The 2026 Mazda SUV lineup spans five distinct models — from the compact CX-30 to the three-row CX-90 — and the fuel consumption figures across that range tell a clear story about powertrain choices and how they translate to real running costs.

Using NRCan's 2026 fuel consumption data, here's where every current Mazda SUV sits, ranked from most efficient to least, with enough context to know what each number actually means.

The 2026 Mazda SUV Fuel Economy Rankings

*Le/100 km (litre-equivalent) is the blended metric used for PHEVs — reflects combined gasoline and electricity use under standard test conditions.

Understanding the PHEV Numbers

The three PHEV models — CX-70 SC PHEV, CX-70 PHEV, and CX-90 PHEV — sit at the top of this ranking by a wide margin. The SC variants of the CX-70 PHEV deliver an NRCan-rated 3.8 Le/100 km combined, with 51 km of full-electric range. The standard CX-70 PHEV and CX-90 PHEV both return 4.2 Le/100 km with 43 km of EV range.

These figures are meaningful for drivers who charge regularly. The blended rating assumes a mix of electric and gasoline driving — so the more daily kilometres you cover within the EV range, the lower your actual per-kilometre fuel cost. Charge overnight with Level 2 (240 V, 30 A), and the battery goes from 20% to 80% in around 1.3 hours.

For drivers whose daily commute sits comfortably under 40–50 km, either PHEV can cover most of that purely on battery. The gasoline engine — a 2.5 L four-cylinder paired with an electric motor for a combined 323 hp and 369 lb-ft of torque — handles longer trips and higher-demand driving without issue.

The Compact Leaders: CX-30 and CX-5

Among gasoline-only models, the CX-30 leads the lineup with an NRCan-rated 8.7 L/100 km combined on the standard naturally aspirated powertrain. Every CX-30 comes with standard i-Activ AWD and uses a Skyactiv-G 2.5 L four-cylinder producing 186 horsepower and 186 lb-ft of torque.

The 2026 CX-5 follows closely at 9.0 L/100 km combined, using the same engine family tuned to 187 hp and 186 lb-ft. That 0.3 L/100 km difference reflects the CX-5's larger footprint — it's a bigger vehicle in every dimension, and one that now carries a redesigned third-generation body.

For buyers comparing these two models on fuel alone, the gap is small enough that other factors — cargo space, passenger room, safety technology — are more likely to tip the decision.

The Inline-Six Models: CX-70 and CX-90 MHEV

The CX-70 and CX-90 both use Mazda's e-Skyactiv G 3.3 L inline-six turbo engine with M-Hybrid Boost, a 48-volt mild-hybrid system. In standard output configuration (280 hp, 332 lb-ft), both the CX-70 and CX-90 return 9.3–9.4 L/100 km combined.

That's a strong result for an inline-six turbo in a large-platform SUV — and it's worth noting that the AJAC recognized this powertrain with its Best Technical Innovation award in 2025, specifically for combining inline-six character with real-world efficiency gains.

The high-output versions — 340 hp, 369 lb-ft — in the CX-70 GT-P, CX-70 Signature, CX-90 GT-P, and CX-90 Signature trim levels each return 9.5 L/100 km combined. The 0.1–0.2 L/100 km premium over the standard-output version is modest for the added performance.

The CX-30 Turbo: Performance with a Trade-Off

One model worth noting separately is the CX-30 Turbo, available on the GT and GT Kuro Edition. At 9.3 L/100 km combined, it matches the CX-70 MHEV's combined figure — but its city consumption of 10.5 L/100 km is the highest in the compact portion of the lineup. The turbo's 250 hp and 320 lb-ft of torque (on premium 93-octane fuel) are significant for a vehicle of that size, but the trade-off in urban fuel use is worth factoring in.

Key Takeaways

• Most efficient (gasoline): CX-30 at 8.7 L/100 km — compact size, standard AWD, 186 hp
• Best efficiency in the full-size segment: CX-90 PHEV at 4.2 Le/100 km with 43 km EV range
• Inline-six efficiency: CX-70 and CX-90 MHEV hold 9.3–9.5 L/100 km across standard and high-output engines
• PHEV advantage is real — with charging access: Without regular charging, PHEV consumption approaches the 9.0–9.2 L/100 km range
