How many miles per gallon does a 2024 Lexus RX 450h+ plug in hybrid get?
The 2024 Lexus RX 450h+ is EPA-rated at about 74 MPGe combined, with an estimated all-electric range of roughly 36 miles. When the battery is depleted, the vehicle operates as a conventional hybrid and delivers around 29 mpg on gasoline. These figures position the RX 450h+ among the more efficient luxury plug-in hybrids in its class.
EPA ratings at a glance
Here are the official EPA estimates that buyers typically reference when evaluating fuel economy for a plug-in SUV.
- MPGe combined: about 74 MPGe, which blends energy use from both electricity and gasoline.
- All-electric range: up to roughly 36 miles on a full battery, according to EPA testing.
- Gasoline-only operation (hybrid mode after EV depletion): about 29 mpg, when the battery is not being charged during operation.
These numbers provide a baseline for comparing the RX 450h+ with other plug-in hybrids and traditional gasoline SUVs.
How real-world use might differ
Actual efficiency depends on how often you recharge, driving style, climate control use, terrain, and cargo load. Plugging in regularly and driving in EV mode for city trips typically yields the best overall efficiency. On longer highway trips, the gasoline engine will contribute more, slightly lowering MPGe but maintaining strong total range.
Charging strategy
Regular Level 2 charging helps maximize EV miles in daily commutes. The vehicle supports household charging setups and can be charged overnight in many homes.
Driving behavior
Smoother acceleration and moderate speeds tend to preserve electric range, while aggressive driving and high-speed highway cruising reduce the electric portion and raise the reliance on the gasoline engine.
Bottom line for prospective buyers
For shoppers prioritizing electric range and efficiency in a luxury family SUV, the 2024 RX 450h+ offers a compelling combination of up to 36 miles of electric driving and strong MPGe, with the backing of Lexus refinement and all-wheel drive as an option. Real-world results will vary with charging habits and driving conditions.
Summary
EPA estimates: ~74 MPGe combined, up to ~36 miles of all-electric range, and around ~29 mpg when running on gasoline in hybrid mode. Real-world results will vary based on charging and driving patterns.
