The 2025 Audi Q8 e-tron quattro with 21-inch wheels gets 74 MPG combined. It’s a statement that this all-electric luxury SUV offers serious performance credentials in a sleek, modern package, not just a basic EV. Buyers prioritize refinement and technology while wanting less gas and the convenience of electric power.

City and highway performance

The EPA estimates 73 MPG in the city and 75 MPG on the highway, a very consistent performance. This reflects the electric powertrain’s efficiency and Audi’s energy management optimization. Gasoline vehicles often have sharply reduced fuel economy in city driving, but the Q8 e-tron maintains its efficiency by using regenerative braking to recapture energy. This is a key advantage for city commuters. On the open road, the Q8 e-tron continues to impress with excellent aerodynamics and a well-tuned electric motor, delivering consistent performance at highway speeds. The slightly higher highway MPG likely reflects the vehicle’s efficiency at a steady cruising speed.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Audi Q8 e-tron quattro to be $1,000. This is based on 15,000 miles per year and national average electricity cost. Individual electricity rates and driving habits will vary, but $1,000 gives a benchmark for potential savings compared to gasoline SUVs. Owners who mainly charge at home with off-peak rates could see significantly lower costs. This also doesn’t include potential maintenance savings, as EVs typically need less upkeep than internal combustion engines.

Real-world expectations

EPA numbers provide guidance, but real-world driving influences fuel economy. Driving style, temperature, and accessory use (air conditioning or heating) can affect the Q8 e-tron’s efficiency. Quick acceleration and high-speed driving reduce range and increase energy use. Extreme temperatures can hurt battery performance. The Q8 e-tron is likely to offer impressive real-world efficiency because of its energy management system and the high efficiency of electric powertrains.

How it compares

The luxury electric SUV segment is competitive. The Jaguar I-PACE gets around 69 MPG combined. The Tesla Model X, in some configurations, reaches 102 MPGe combined, but has a different price and design. The BMW iX gets about 84 MPG combined. These numbers are important, but Q8 e-tron buyers often value Audi’s interior, build quality, and brand. They might accept small efficiency compromises for the total Audi experience.

Tips to maximize efficiency

Preconditioning the cabin while plugged in, or shortly before leaving, can extend range. Warming or cooling the interior while connected to the charger reduces the battery’s energy use. This is helpful in cold weather, where heating greatly impacts battery performance.

Gentle acceleration and consistent speeds are key for maximizing efficiency in any EV. The Q8 e-tron has ample power, but avoiding fast acceleration helps conserve energy and extend your range. Anticipating traffic and keeping a steady pace improves fuel economy.

Effectively use the Q8 e-tron’s regenerative braking system. Lifting off the accelerator gradually lets you recapture energy and slow the car without using the brakes. This extends range and reduces brake wear. Try different regenerative braking modes to find your preference.

Check tire pressure regularly. Properly inflated tires reduce rolling resistance and improve fuel economy. See the sticker on the driver’s side doorjamb for the recommended tire pressure. Small differences in tire pressure can impact efficiency, so check them monthly.
