The 2024 Audi Q8 e-tron quattro gets 81 MPG combined, placing it at the top of the luxury electric SUV class for efficiency. This is not just good for an SUV, it’s an exceptional figure that rivals many dedicated electric sedans. All this is achieved in a spacious, comfortable, and technologically advanced vehicle. Buyers choosing the Q8 e-tron prioritize a combination of lower fuel costs, luxury, and practicality. The electric powertrain allows them to enjoy trademark Audi refinement without using gas.

City and highway performance

Breaking down the Q8 e-tron’s efficiency reveals its strengths. The EPA estimates 80 MPG in city driving and 83 MPG on the highway. The near-identical numbers highlight the electric motor’s consistent efficiency across different driving conditions. Traditional gasoline vehicles often struggle to achieve similar MPG figures in city and highway driving, but the Q8 e-tron thrives on its predictable and balanced performance. Its instant torque assists low-speed acceleration in cities, while optimized aerodynamics maximize efficiency at cruising speeds. This consistency is a key selling point for buyers who may split time between urban commutes and longer road trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Audi Q8 e-tron quattro at $950. This figure assumes 15,000 miles of driving per year, using the national average electricity prices. This cost-saving is a significant draw for electric vehicle owners since they no longer have to worry about fluctuating gasoline prices. Depending on individual driving habits and charging behavior, many owners will likely spend even less. Home charging during off-peak hours can dramatically reduce electricity costs compared to public charging stations. Some may even supplement with solar power, and for them, “fuel” may be virtually free.

Real-world expectations

While the EPA estimates provide a solid baseline, real-world driving conditions impact efficiency. Factors such as ambient temperature, driving style, and road conditions can cause results to fluctuate. Aggressive acceleration, frequent hard braking, and sustained high speeds will reduce overall efficiency. Using climate-control features, especially heating and air conditioning, also draws power and shortens range. Even under less-than-ideal conditions, the efficient electric powertrain generally delivers impressive range and MPG figures if the driver is mindful of energy consumption.

How it compares

The Q8 e-tron holds its own amongst a growing list of electric luxury SUVs. The Jaguar I-Pace achieves a combined 76 MPG, showing the Audi’s superior efficiency. The BMW iX xDrive50 matches the Q8 e-tron’s 81 MPG combined, but at times suffers range anxiety. Even within the wider luxury SUV class, the Q8 e-tron’s efficiency shines. Comparing it to gasoline-powered alternatives underscores the advantages of electric power. For instance, the Mercedes-Benz GLE 450 4MATIC achieves 23 MPG combined (EPA estimate). The Q8 e-tron is appealing because of its fuel efficiency, which enables an engaging driving experience without the guilt of traditional gasoline engines.

Tips to maximize efficiency

Employ regenerative braking modes strategically. The Q8 e-tron features adjustable regenerative braking, allowing drivers to recover energy during deceleration. Choosing a higher regeneration setting captures more energy, which can increase overall efficiency. Use the paddles for one-pedal-driving mode to allow the driver to decelerate and nearly stop without using the brake pedal. This extends the time regenerative braking is employed.

Precondition the cabin while plugged in. Heating or cooling the cabin while the vehicle is connected to a charger can reduce energy consumption during initial driving. This minimizes the draw on the battery, especially on cold days when heating systems require substantial power.

Optimize tire pressure. Ensuring tires are inflated to the recommended pressure improves efficiency and enhances handling. Underinflated tires increase rolling resistance, which requires more energy to maintain speed. Audi offers all Audi fuel economy data, and proper tire inflation is one of the tips provided.

Smooth and steady acceleration is key. Electric motors offer instant torque, but aggressive acceleration drains the battery quickly. Gentle acceleration and maintaining a consistent speed optimize efficiency and extend range. Read other articles on Q8 MPG across all years to get a better idea of performance.

Minimize aerodynamic drag. Removing unnecessary roof racks or cargo carriers reduces aerodynamic drag, improving efficiency, especially at highway speeds. Keeping the Q8 e-tron’s exterior clean also helps minimize drag and maximize range on road trips.
