81 MPGe combined makes the 2025 Volvo EX90 Twin Motor a genuine revelation in the luxury three-row SUV segment. This shows how dedicated electrification can transform the efficiency of a traditionally thirsty vehicle class. This isn’t just a respectable number; it’s a bold statement from Volvo, signaling a future where family-haulers can deliver both opulent comfort and extraordinary energy conservation. The EX90 is designed for the individual who demands uncompromising safety, cutting-edge technology, and now, exceptional electric miles, without sacrificing the space and capability expected from a full-size SUV. They understand that a vehicle of this size, weight, and luxury, even when electric, has significant energy requirements, and 81 MPGe represents a masterful engineering achievement.

City and highway performance

The EX90 Twin Motor’s city efficiency, rated at 83 MPGe, is particularly impressive, highlighting the inherent advantages of electric powertrains in urban environments. Stop-and-go traffic, often a nemesis to internal combustion engines, becomes a regenerative playground for the EX90. The immediate torque delivery of its twin electric motors means effortlessly surging ahead from traffic lights, while the smooth regenerative braking system recaptures energy that would otherwise be lost as heat in conventional brakes. This translates to an exceptionally smooth, quiet, and efficient commute, precisely what the typical EX90 buyer seeks for daily school runs, grocery trips, and urban excursions. On the highway, the EX90 still shines with 78 MPGe, a figure that remains highly competitive. While sustained higher speeds naturally increase energy consumption due to aerodynamic drag, Volvo’s thermal management and powertrain optimization ensure that long-distance travel is both remarkably efficient and quiet and comfortable. The vehicle’s aerodynamic design, despite its substantial footprint, plays a crucial role in maintaining this impressive highway figure, ensuring that longer journeys don’t disproportionately impact the range or the perceived cost of travel.

Annual fuel cost

The EPA estimates an annual fuel cost of $950 for the 2025 Volvo EX90 Twin Motor. This figure, calculated based on 15,000 miles of driving per year and national average electricity costs, underscores a significant economic benefit. For a large, premium three-row SUV, a sub-$1,000 annual energy bill is remarkable. This financial outlay is substantially lower than what owners of comparable gasoline-powered vehicles would face, representing tangible savings that contribute to the overall value of the EX90. It means more budget flexibility for other family needs, or simply a lower total cost of ownership for a vehicle that already commands a premium price point. This financial transparency is a key selling point for the pragmatic luxury buyer.

Real-world expectations

While the EPA ratings provide an excellent benchmark, real-world efficiency in the EX90 Twin Motor, like any EV, will vary based on several factors. Drivers should reasonably expect to achieve figures very close to the EPA estimates under typical conditions. Aggressive driving, frequent high-speed highway travel, or consistent operation in extremely cold climates will inevitably see efficiency dip, as the battery works harder to maintain cabin temperature and range. Conversely, drivers with a lighter foot, who maximize regenerative braking and pre-condition the cabin while plugged in, may even exceed the stated numbers. The expansive glass roof, while adding to the interior ambiance, can contribute to climate control demands, particularly in direct sunlight or extreme cold. The generous cargo capacity means some owners will frequently ferry heavier loads, which will also impact energy consumption. Understanding these dynamics is crucial for any EV owner, and the EX90’s onboard computer and driver assistance systems are designed to provide real-time feedback to help optimize efficiency.

How it compares

The EX90 Twin Motor directly challenges the efficiency benchmarks set by other luxury EV SUVs, particularly within the three-row segment. Consider its closest competitor, the Rivian R1S Dual-Motor, which achieves an admirable 73 MPGe combined. While a strong contender, the EX90 still holds a noticeable lead. The Mercedes-Benz EQS SUV 450 4MATIC, another luxury electric three-row, offers 79 MPGe combined, placing it quite close to the EX90 but still slightly behind. Even the potent Tesla Model X Plaid, an extremely quick performer, delivers 97 MPGe combined, but it carries a different mission with its performance focus and slightly less dedicated three-row practicality than the Volvo. For those considering traditional combustion luxury SUVs, the disparity is stark. A gasoline-powered Audi Q7 45 TFSI manages only 22 MPG combined, while the Cadillac Escalade ESV V8 struggles with 16 MPG combined. These comparisons vividly illustrate the EX90’s leadership in energy efficiency for its class, making it an undeniable choice for those prioritizing sustainability and lower running costs without sacrificing size or luxury.

Tips to maximize efficiency

Maintain consistent tire pressure, especially with the 20 and 22-inch wheel options. Proper inflation reduces rolling resistance, directly translating to less energy consumed to move the EX90’s substantial weight, noticeably impacting both city and highway MPGe.

Use the EX90’s “One Pedal Drive” mode effectively. This feature allows for maximum regenerative braking, turning deceleration into energy recapture and significantly extending real-world range, particularly in stop-and-go urban traffic.

Pre-condition the cabin while the EX90 is still plugged in. Heating or cooling the interior using grid power rather than battery power before starting your journey conserves the battery’s charge for propulsion, especially on shorter trips.

Consider your driving style, smooth acceleration and anticipation of traffic conditions are important. Abrupt starts and hard braking force the motors and battery to work less efficiently, directly impacting your MPGe.

Avoid unnecessary weight in the vehicle. While the EX90 is designed to carry substantial loads, removing unused cargo from the spacious interior reduces the energy required for every mile traveled.
