If you've searched "Audi Q5 mpg," you're probably comparing efficiency numbers before committing to your next SUV. The most important thing to understand is this: most results you'll find online show U.S. EPA figures that don't apply here. The Audi Q5 carries official Canadian fuel consumption ratings measured in L/100 km, and that's the number that matters when you're filling up along the QEW or Highway 403 near Oakville.

Official 2026 Audi Q5 Fuel Consumption Ratings

Canadian fuel economy is published in litres per 100 kilometres. Lower means more efficient. For context, the combined rating also converts to an approximate miles-per-gallon figure below. All Q5 variants require premium gasoline.

Here are the official ratings for the latest  model year:

Q5 TFSI quattro (2.0L 4-cylinder, 7-speed automated manual)

• City: 11.0 L/100 km
• Highway: 8.1 L/100 km
• Combined: 9.7 L/100 km (29 mpg)

SQ5 quattro (3.0L 6-cylinder, 7-speed automated manual)

• City: 11.5 L/100 km
• Highway: 8.5 L/100 km
• Combined: 10.1 L/100 km (28 mpg)

What Separates the Q5 From the SQ5

The standard Q5 uses a turbocharged 2.0L four-cylinder producing up to 268 hp and 295 lb-ft of torque. It pairs with quattro all-wheel drive. The SQ5 moves up to a 3.0L six-cylinder, which adds power but increases consumption by roughly 0.4 L/100 km combined. For most buyers, that's a reasonable trade-off for the added capability.

A Quick Note on Audi Q5 MPG vs. L/100 km

Many Canadian shoppers search in miles per gallon because U.S. sources tend to dominate online results. But every vehicle sold in Canada is rated in L/100 km through the official Canadian testing programme. Throughout this article, you'll find both formats side by side so the numbers are easy to read however you're used to them.

What Q5 Owners Actually See at the Pump

Official ratings come from standardized lab tests. They're useful for comparing vehicles on equal footing, but real-world consumption shifts based on how and where you drive.

Four factors consistently influence what you'll actually see:

• Highway cruising at steady speeds typically brings you close to, or sometimes under, the 8.1 L/100 km highway figure
• Stop-and-go traffic around Mississauga or Milton intersections pushes consumption above the city rating
• Cargo weight and passenger load add incremental fuel use
• Tire pressure matters more than most drivers expect; even slightly low tires increase rolling resistance and fuel use

For drivers commuting along the QEW between Oakville and Burlington, the highway figure is the most relevant benchmark. Longer stretches at consistent speeds let the Q5 drivetrain operate in its most efficient range.

How Audi Drive Select Affects Audi Q5 Fuel Economy

The Q5 includes Audi Drive Select, which adjusts throttle response, steering weight, and other vehicle parameters. Choosing the Efficiency setting softens throttle mapping so the engine isn't working as hard during gentle acceleration. It's a simple toggle that can make a meaningful difference on your daily commute around Oakville or Burlington.

Dynamic mode, by contrast, sharpens everything for a sportier feel. Engaging on a weekend drive, but expect higher fuel use. For everyday errands and highway commuting, Efficiency or Comfort modes keep consumption closer to the published ratings.

Cold-Weather Fuel Economy in Ontario

Ontario winters affect every vehicle's efficiency. Cold air is denser, engine warm-up cycles run longer, and winter-blend fuel carries slightly less energy per litre. As a result, your Q5 will likely consume more fuel between November and March than during the warmer months.

A few habits help offset the seasonal increase:

• Park in a garage when possible so the engine starts closer to operating temperature
• Avoid prolonged idling; modern engines warm up faster when driven gently from the start
• Keep winter tires inflated to their recommended pressure
• Remove roof-mounted accessories like cargo boxes when they're not in use, since they add aerodynamic drag

These adjustments won't eliminate the winter penalty. But they add up over a full Ontario season.

Practical Tips to Maximize Your Q5 Efficiency

Beyond Drive Select and winter preparation, a few consistent driving habits help:

• Accelerate smoothly from stops rather than aggressively
• Anticipate traffic flow and coast toward red lights instead of braking late
• Use cruise control on Highway 403 or the QEW to maintain steady-speed efficiency
• Follow the recommended maintenance schedule so the engine and drivetrain stay in good condition; book a service appointment at Audi Oakville to stay on track
• Fill up with the required premium gasoline; lower-octane fuel can reduce efficiency in turbocharged engines

Frequently Asked Questions

What fuel economy does the 2026 Audi Q5 get in L/100 km?

The Q5 TFSI quattro with its 2.0L four-cylinder is rated at 11.0 L/100 km city, 8.1 L/100 km highway, and 9.7 L/100 km combined. The SQ5 quattro, powered by a 3.0L six-cylinder, comes in at 11.5 city, 8.5 highway, and 10.1 combined. Actual results vary with driving style, weather, and route. Highway-heavy commuters near Oakville and Burlington will likely track closer to the highway figure in everyday use.

How many miles per gallon does the 2026 Audi Q5 get?

The combined rating for the Q5 TFSI quattro converts to approximately 29 mpg. The SQ5 quattro sits at about 28 mpg combined. Canadian ratings use L/100 km as the official standard, so the mpg figures are approximate conversions provided for easy comparison with U.S. sources. A lower L/100 km number always indicates better efficiency.

Does the 2026 Audi Q5 require premium gasoline?

Yes. Both the Q5 TFSI quattro and SQ5 quattro require premium gasoline. Using a lower octane than recommended can reduce efficiency and may affect engine performance in turbocharged powertrains. For reliable consumption figures, always fill up with the grade specified by the manufacturer. The service team at Audi Oakville can advise on fuel and maintenance requirements specific to your vehicle.

How does Audi Drive Select affect Q5 fuel consumption?

Switching to the Efficiency setting adjusts throttle response and other vehicle systems to favour lower fuel use. It's a practical choice for daily commuting and highway driving in Ontario. Dynamic mode prioritizes performance and responsiveness, which typically increases consumption. Most drivers find that Comfort or Efficiency mode strikes the right balance for everyday use on local roads.

Is the SQ5 much less fuel-efficient than the standard Q5?

The difference is modest. The SQ5 quattro uses about 0.4 L/100 km more than the standard Q5 TFSI quattro on a combined basis, 10.1 versus 9.7 L/100 km. In mpg terms, that's roughly 28 versus 29. The SQ5 3.0L six-cylinder delivers considerably more power, so the slight increase in consumption is proportional. It remains a refined and capable daily driver for Ontario conditions.

Does cold weather affect the Q5 fuel economy in Ontario?

Yes, and Ontario winters are a real factor. Denser cold air, longer engine warm-up cycles, and winter-blend gasoline all contribute to higher consumption. Drivers may notice their Q5 using noticeably more fuel from late autumn through early spring. Modern turbocharged engines manage cold starts more efficiently than previous generations, but parking indoors, avoiding extended idling, and maintaining proper tire pressure still help reduce the seasonal impact on your fuel budget.

Where can Ontario drivers learn more about the 2026 Q5?

Audi Oakville serves drivers throughout Oakville, Burlington, Mississauga, and Milton. The team can walk you through the full Q5 and SQ5 lineup and help identify a configuration suited to your commute and lifestyle.
