The 2021 Audi SQ5 3.0L 6-cyl gets 20 MPG combined, which isn’t going to win any awards for less gas usage, but it’s an expected tradeoff for a vehicle designed to deliver luxury and performance. This isn’t a hybrid or a fuel-sipping commuter; it’s a compact SUV with a punchy V6 engine and Audi’s renowned quattro all-wheel-drive system. The fuel economy is a reflection of getting 349 horsepower and confident roadholding from a relatively small package.

City and highway performance

The EPA estimates of 18 MPG in the city and 24 MPG on the highway provide a more detailed picture of the SQ5’s fuel consumption. The city figure, unsurprisingly, is the lower of the two, reflecting the stop-and-go driving conditions that put a strain on fuel efficiency. The turbocharged 3.0-liter V6 needs more fuel to accelerate from a standstill, and idling at traffic lights contributes to lower MPG.

Out on the open road, the SQ5 settles into a more efficient cruising mode, allowing the engine to operate in its optimal range and delivering a more respectable 24 MPG. This makes the SQ5 a decent choice for longer road trips, even if it won’t rival a dedicated fuel-efficient vehicle.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Audi SQ5 at $2,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for comparing the SQ5’s running costs to other vehicles, but it’s important to remember that your actual fuel expenses may vary depending on your driving habits, location, and local fuel prices. If you tend to drive mostly in the city or have a lead foot, expect to spend more than the estimated $2,900. Careful driving and optimized routes can potentially lower that figure.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy often differs. SQ5 owners often report figures that are close to the EPA estimates, but variations are inevitable. Factors like driving style, traffic conditions, and even tire pressure can influence how much fuel the SQ5 consumes. Aggressive acceleration, frequent hard braking, and neglecting routine maintenance will all negatively impact fuel efficiency. The SQ5’s quattro all-wheel-drive system, while enhancing traction and handling, also adds weight and complexity, contributing to slightly lower fuel economy compared to front-wheel-drive vehicles.

How it compares

In the competitive landscape of compact luxury SUVs, the SQ5’s fuel economy sits mid-pack. The BMW X3 M40i, another performance-oriented option, achieves an EPA-estimated 21 MPG combined. The Mercedes-AMG GLC 43 offers a similar blend of performance and luxury, also landing around 20 MPG combined. The Acura RDX, with its turbocharged four-cylinder engine, boasts a slightly more frugal 23 MPG combined. The Porsche Macan S, arguably the SQ5’s closest rival in terms of driving dynamics, posts official figures of 19 MPG combined. The Lexus NX hybrid, in contrast, delivers significantly better economy, around 39 MPG combined. For buyers prioritizing performance and luxury over less gas usage, the SQ5 remains a good option.

Tips to maximize efficiency

Use Audi Drive Select to optimize the SQ5’s performance for efficiency. Selecting “Efficiency” mode will adjust engine mapping, transmission shift points, and even climate control settings to prioritize fuel conservation. “Dynamic” mode unleashes the car’s full potential, at the expense of fuel economy. Choose the appropriate mode for the driving conditions.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure for your SQ5. A simple tire pressure gauge and a few minutes of your time can make a noticeable difference.

Avoid unnecessary idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute, turn off the engine. Modern cars, including the Audi SQ5, are designed to restart reliably and efficiently. Minimizing idling can significantly reduce fuel consumption, especially in city driving.

Practice smooth acceleration and braking. Aggressive driving habits consume significantly more fuel. Anticipate traffic flow, maintain a steady pace, and avoid sudden acceleration or hard braking. The SQ5’s powerful engine can easily encourage spirited driving, but a more measured approach will reward you with improved fuel economy. Use cruise control on the highway for consistent speed. and greater efficiency. Explore the SQ5 MPG across all years to identify trends and potential areas for improvement.
