The 2023 Lexus RX 350h AWD gets 36 MPG combined, making it a comfortable, luxurious, and surprisingly efficient mid-size crossover. Hybrids aren’t slow or unrefined anymore; this RX sips fuel while delivering the premium experience Lexus buyers demand. It’s a good choice for those wanting lower long-term running costs without giving up the features and status of a luxury brand.

City and highway performance

The RX 350h is great for city driving, achieving an EPA-estimated 37 MPG. This urban efficiency comes from the hybrid system’s ability to operate in electric-only mode at lower speeds. Regenerative braking recovers energy lost when slowing down. On the highway, the RX 350h gets a respectable 34 MPG, making it good for long trips. While its highway MPG isn’t dramatically better than its city MPG, it’s still a solid number for an all-wheel-drive crossover, especially one with the RX’s refinement. This balanced performance makes it ideal for drivers who commute in the city and take weekend road trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Lexus RX 350h AWD at $1,600. This is based on driving 15,000 miles per year and using national average fuel prices. This gives buyers a benchmark to compare the RX 350h’s running costs to other vehicles. For those driving more or less than 15,000 miles a year, the fuel cost will change based on driving style and fuel prices.

Real-world expectations

EPA figures are a baseline, but real-world fuel economy changes depending on driving habits and conditions. Hard acceleration, frequent hard braking, and speeding all hurt fuel efficiency. Extreme temperatures or hilly terrain may also lower MPG. However, a careful driving style with smooth acceleration and anticipating traffic can help you match or exceed the EPA estimates. All-wheel-drive systems add some drag, reducing fuel economy compared to a two-wheel-drive car (but the RX doesn’t have one).

How it compares

The RX 350h’s fuel economy is good compared to its rivals. The Acura MDX gets around 21-22 MPG combined in its standard form. The MDX hybrid gets only around 27 MPG combined. The BMW X5, while offering a plug-in hybrid, generally gets combined MPG in the low 20s for its non-hybrid models. The Volvo XC60 Recharge plug-in hybrid can get great MPGe when charged, but its gas-only MPG is around 28. Even smaller crossovers like the Audi Q5 get around 26 MPG combined. The RX 350h offers luxury and efficiency that competitors can’t match without plug-in hybrid tech. For all Lexus fuel economy data, looking at other models shows the brand’s focus on being efficient.

Tips to maximize efficiency

Use the RX 350h’s Eco mode. This setting changes the engine and transmission for fuel efficiency, using electric-only driving and reducing throttle response. It’s good for commuting and helps you accelerate gently.

Keep your tires inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure every two weeks, and inflate them to the recommended pressure on the driver’s side doorjamb. You can also view RX MPG across all years to understand tire impacts in prior years.

Anticipate traffic and avoid sudden acceleration and braking. Hybrid systems work best with smooth driving. By looking ahead and gently accelerating or slowing down, you’ll maximize regenerative braking and minimize the gasoline engine turning on.

Reduce weight. Extra cargo adds weight, which reduces fuel economy. Remove items you don’t need from the trunk and passenger area. Leaving golf clubs in the trunk for daily commutes is unnecessary.
