84 MPGe combined for the 2025 Volvo EX90 Twin Motor Performance with 21-inch wheels is an impressive figure. This vehicle redefines luxury and sustainability in the three-row electric SUV segment. It is a heavy, powerful, meticulously crafted Swedish vehicle that sips electricity with remarkable efficiency. The EX90 buyer embraces this vehicle not as a compromise, but as the evolution of family transportation. They are investing in a future where speed, safety, and lower fuel costs coexist, and the EX90 makes that transition feel effortless.

City and highway performance

The EPA rates the EX90 Twin Motor Performance at 86 MPGe in the city and 82 MPGe on the highway. This marginal difference between urban and open-road efficiency highlights a fundamental advantage of electric powertrains. Unlike internal combustion engines, which often struggle with stop-and-go traffic, electric vehicles like the EX90 excel in city driving, reclaiming energy through regenerative braking. The vehicle’s hefty 111 kWh battery, paired with its advanced dual-motor setup, allows for consistent and strong performance irrespective of the driving environment. On the highway, the EX90 maintains its composure and efficiency, though the sheer scale of the vehicle and the aerodynamic resistance inherent in an SUV format mean the gains are not quite as pronounced as in a smaller EV. What is significant here is the consistent delivery of its impressive 496 horsepower and 671 lb-ft of torque without a substantial penalty in efficiency regardless of the scenario.

Annual fuel cost

The EPA estimates an annual fuel cost of $900 for the 2025 Volvo EX90 Twin Motor Performance. This figure is based on an average of 15,000 miles driven per year, assuming national average electricity prices. For the EX90 owner, this annual expenditure represents a substantial saving compared to a similarly sized gasoline-powered luxury SUV. This $900 figure underscores the tangible financial benefit of electrification, offering a predictable and comparatively low cost of operation that aligns perfectly with the premium experience Volvo delivers. It is a key part of the value for a vehicle that commands a significant upfront investment, confirming that the long-term running costs are refreshingly modest.

Real-world expectations

The 84 MPGe combined rating for the EX90 Twin Motor Performance is a strong benchmark, but real-world results will naturally vary. Factors such as driving style, ambient temperature, topography, and payload all influence actual efficiency. Aggressive acceleration and consistent high-speed cruising, which are undeniably tempting with 496 horsepower on tap, will push the consumption higher. Conversely, a disciplined driver using regenerative braking effectively in urban environments will see numbers close to, or even exceeding, the EPA estimates. The 21-inch wheels, while visually striking, inherently introduce a slight aerodynamic and rolling resistance penalty compared to smaller wheel options, but the impact is generally minor in the grand scheme of an SUV this size. Owners can expect a practical range exceeding 300 miles on a full charge under favorable conditions, which remains more than adequate for most daily commutes and even longer road trips, backed by a rapidly expanding charging infrastructure.

How it compares

In the competitive landscape of three-row electric SUVs, the EX90 Twin Motor Performance with its 84 MPGe combined rating holds its own against key rivals. Consider the Rivian R1S Dual-Motor Large Pack, a strong choice for adventurous families. The R1S, in its large battery configuration, typically achieves around 73 MPGe combined. While still excellent, the EX90 demonstrates superior energy management. Moving to luxury stalwarts, the Mercedes-Benz EQS SUV 450 4MATIC is rated at 79 MPGe combined, marginally behind the Volvo. These comparisons highlight Volvo’s engineering prowess, achieving a higher MPGe while still delivering strong performance and the brand’s signature emphasis on safety and sophisticated design. The buyer here is not necessarily cross-shopping a Tesla Model X Plaid (102 MPGe combined, but a vastly different aesthetic and mission), but rather looking at vehicles that blend luxury, practicality, and future-forward technology for the everyday family.

Tips to maximize efficiency

Mindful driving is the single most effective way to optimize the EX90’s efficiency. Smooth acceleration and proactive braking, using the car’s excellent regenerative capabilities, can significantly extend your practical range. Avoid sudden bursts of speed unless absolutely necessary.

Pre-conditioning the cabin while the EX90 is still plugged into a charger reduces the drain on the battery once you start your journey. This is particularly effective in extreme hot or cold weather, ensuring primary battery power is conserved for propulsion.

Maintain proper tire pressure. Under-inflated tires increase rolling resistance, forcing the motors to work harder to maintain speed. Check your tire pressure regularly, especially with the EX90’s large 21-inch wheels.

Strategic use of “One Pedal Drive” mode can enhance efficiency and provide a more relaxed driving experience. This feature allows for maximum energy recuperation, converting kinetic energy back into electricity and reducing reliance on the friction brakes.

Plan your routes to avoid excessive uphill climbs when possible, and generally aim for smoother, less congested roads. Each elevation gain demands more energy, while consistent speeds on level ground are ideal for electric vehicle efficiency.
