The 2024 Audi SQ8 e-tron, when equipped with the 20-inch wheels, achieves an EPA-estimated 73 MPG combined. That’s remarkably high for a performance-oriented, all-electric SUV that delivers blistering acceleration and comfortably seats five. This isn’t your hyper-efficient, stripped-down EV, it’s a luxury vehicle designed for drivers who want thrilling performance and lower fuel costs, and who are willing to accept some real-world range compromises to get it.

City and highway performance

The EPA breaks down that 73 MPG combined rating further, showing 72 MPG in the city and 75 MPG on the highway. This highlights the efficiency of the electric powertrain in stop-and-go conditions. While the highway figure is slightly higher, drivers shouldn’t solely focus on it. The SQ8 e-tron’s electric motors provide instant torque, making it incredibly responsive for passing and merging, and this capability impacts efficiency at higher speeds. However, the aerodynamic design and efficient energy management systems help maintain a respectable highway figure, minimizing range anxiety on longer journeys. The highway rating also reflects its advanced driver-assistance features, optimizing speed and distance for maximum energy conservation.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Audi SQ8 e-tron is $1,050. This figure is based on driving 15,000 miles per year, using a combination of city and highway driving, and factoring in the national average electricity prices. This is a substantial savings for many drivers, though electricity costs and driving habits will have a considerable effect on this number.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPG can vary depending on several factors. Driving style is a primary influence, aggressive acceleration and high-speed cruising will deplete the battery charge faster. Ambient temperature also plays a role, as colder conditions can reduce battery efficiency. Using features like climate control systems will also consume additional energy, further impacting real-world figures. However, the SQ8 e-tron’s energy management system is designed to mitigate these effects.

The regenerative braking system, for example, recaptures energy during deceleration, helping extend the driving range. And preconditioning the cabin temperature while the vehicle is plugged in can minimize the energy draw while driving. Most SQ8 e-tron owners aren’t solely focused on maximizing efficiency; they want a sporty and luxurious driving experience, but they do expect the convenience of electric power and reasonable running costs.

How it compares

Compared to other performance-oriented SUVs, the SQ8 e-tron stands out in terms of MPG. The BMW X5 M60i, a gasoline-powered SUV with similar performance aspirations, manages just 19 MPG combined. Even hybrid SUVs like the Lexus RX 450h+ only achieve 83 MPGe combined, due to the limitations of the hybrid powertrain. The all-electric powertrain of the SQ8 e-tron offers a significant advantage, especially for drivers who prioritize fuel efficiency and less gas, while demanding high levels of performance.

Buyers also might cross-shop against the standard Q8 e-tron, or browse SQ8 MPG across all years to consider if they want to trade some performance for increased efficiency.

Tips to maximize efficiency

Take advantage of regenerative braking. The SQ8 e-tron offers adjustable regenerative braking settings, allowing you to optimize energy recuperation depending on driving conditions. Experiment with different levels of regeneration to find the one that best suits your style and route. You can usually increase your MPG in almost any car by simply taking your foot off the accelerator sooner.

Precondition the cabin before driving. Many drivers don’t use the preconditioning setting because they don’t understand how much energy they save during operation. When the SQ8 e-tron is plugged in, use the vehicle’s app or infotainment system to preheat or precool the cabin before your trip. This reduces the energy required to maintain a comfortable temperature while driving, especially in extreme climates.

Maintain optimal tire pressure. Low tire pressure increases rolling resistance, which negatively impacts fuel economy. Regularly check your tires and inflate them to the recommended pressure specified on the doorjamb sticker. Also, consider using low rolling resistance tires when it’s time for a replacement.

Minimize use of accessories impacting range. While the SQ8 e-tron’s features enhance comfort and convenience, they also consume energy. Limit the use of power-draining accessories like seat heaters and high-powered audio systems, especially on shorter journeys. And of course, reducing your speeds, especially on the highway, can result in significant gains.
