A combined 36 MPG makes the 2025 Lexus RX 350h AWD an efficient luxury crossover. This figure helps it stand out in the competitive premium segment. This is a vehicle for those who value comfort and refinement but also want good everyday practicality, especially at the gas pump. The RX 350h is an engineered solution for buyers seeking a quiet driving experience coupled with low running costs. It’s for the professional who commutes daily, the couple who road-trips on weekends, or the family whose busy schedule demands reliability and efficiency without sacrificing luxury.

City and highway performance

The 2025 Lexus RX 350h delivers 37 MPG in the city and 34 MPG on the highway, figures that showcase the synergy of its hybrid powertrain. The 2.5L 4-cylinder engine, paired with Lexus’s well-tuned automatic (AV-S6) transmission, is particularly adept at navigating urban environments. In stop-and-go traffic, the electric motors frequently propel the vehicle, allowing the internal combustion engine to shut down and conserve fuel. This is where the 350h shines, offering near-silent operation and instantaneous torque off the line. On the open road, the system intelligently balances gasoline and electric power, maintaining the refined cruising characteristics Lexus buyers expect. While the city figure is marginally higher, the highway performance remains excellent, ensuring long journeys are met with minimal fuel stops and maximum comfort. This balance makes the RX 350h an ideal companion for a wide range of driving scenarios, consistently delivering efficiency whether hustling through urban centers or maintaining speed on interstates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Lexus RX 350h AWD to be an approximate $1,600 per year. This figure is based on an industry standard calculation of driving 15,000 miles over a year, with a split of 45% city driving and 55% highway driving, using national average fuel prices. For a luxury crossover of its size and capability, this is an outstandingly low cost of ownership from a fuel perspective. The $1,600 estimate positions the RX 350h as a financially smart choice, reassuring buyers who prioritize long-term value alongside initial luxury. This predictable and modest annual expense is a significant selling point, appealing to those who meticulously budget their household or business expenditures. The hybrid system effectively minimizes trips to the gas station, translating directly into tangible savings over the vehicle’s lifespan.

Real-world expectations

In real-world driving, the 2025 Lexus RX 350h AWD largely lives up to its EPA ratings. Drivers accustomed to conventional gasoline engines will notice a distinct improvement in fuel efficiency, especially in scenarios involving frequent deceleration and acceleration. The power management system transitions between electric and gasoline power, often imperceptibly to the driver. While aggressive driving or consistent high-speed highway cruising will naturally dip slightly below the EPA figures, moderate driving habits will consistently keep the RX 350h in the high 30s for combined MPG. Owners appreciate the quiet operations and the minimal need to engage the gasoline engine during low-speed maneuvers or when coasting. The hybrid system’s reliable integration ensures that fuel economy isn’t achieved at the expense of the smooth, capable driving experience inherent to the Lexus brand.

How it compares

The 2025 Lexus RX 350h AWD sets a high bar for fuel economy in the luxury crossover segment. Its 36 MPG combined rating significantly outperforms many of its direct competitors. Consider the Acura MDX, which, even in its most efficient FWD configuration, only manages 22 MPG combined. The Genesis GV70 with its 2.5T AWD engine offers a combined 24 MPG, a respectable number but still far short of the RX 350h. Even hybrids from other luxury brands often fall short; the Volvo XC60 Recharge, a plug-in hybrid, boasts an impressive 63 MPGe but its gasoline-only combined MPG is 28, and it commands a higher price point and requires regular charging to maximize efficiency. The Cadillac XT5, in its most efficient FWD trim, only reaches 21 MPG combined. This stark contrast highlights the RX 350h’s unique position for buyers who desire genuine luxury and advanced safety features but refuse to settle for subpar fuel economy. It demonstrates Lexus’s commitment to hybrid technology as a core component of its luxury offering, appealing directly to those who value efficiency as much as the badge on the grille.

Tips to maximize efficiency

Maintaining a smooth driving style is important for optimizing the RX 350h’s fuel economy. Gentle acceleration and anticipation of traffic conditions allow the hybrid system to operate more frequently in electric-only mode, particularly in urban settings. Rapid acceleration forces the gasoline engine to work harder, reducing efficiency.

Using regenerative braking effectively also boosts MPG. Instead of abrupt stops, gradually ease off the accelerator and allow the vehicle to coast to a stop. This maximizes the energy captured and stored in the battery, reducing the need for the gasoline engine to recharge it.

Regular maintenance, including proper tire inflation, is crucial for any vehicle, but especially for hybrids. Underinflated tires increase rolling resistance, forcing the powertrain to work harder and consume more fuel. Adhere to Lexus’s recommended service schedule to ensure all systems are operating at peak efficiency.

Minimizing unnecessary weight and drag further enhances fuel economy. Remove any heavy items not needed for your journey from the trunk and avoid roof racks or cargo carriers unless absolutely necessary. These small changes can cumulatively impact efficiency, particularly on longer trips.

Where possible, use the “Eco” driving mode. This setting optimizes throttle response and climate control to prioritize fuel efficiency, making it easier to maintain an economical driving style. While it may slightly dull acceleration, the long-term fuel savings are substantial.
