How many miles per gallon does the 2024 Lexus RX 450h+ get?
The 2024 Lexus RX 450h+ delivers about 74 MPGe combined (electric plus gasoline) and roughly 29 mpg when the battery is depleted, with up to around 38 miles of all-electric range.
EPA ratings at a glance
Official efficiency metrics from the EPA reflect the RX 450h+'s plug-in hybrid design, which blends a gasoline engine with electric propulsion. The vehicle operates in three modes: full electric, hybrid, and gasoline-only once the battery is low.
- MPGe: 74 miles per gallon-equivalent combined (electric and gasoline)
- All-electric range: Up to about 38 miles on a full battery (EPA-estimated)
- Gasoline-only fuel economy: Around 29 mpg combined when the battery isn’t charged
These figures give drivers a sense of efficiency across typical use cases, from short commutes to highway trips.
Real-world driving implications
In daily use, actual efficiency varies with driving style, climate, and charging habits. City driving that keeps the vehicle in EV mode can push MPGe higher, while cold weather and sustained high-speed cruising can reduce electric range and mpg. Lexus' software also helps optimize when the electric motor engages to maximize efficiency.
- Effect of driving style: Frequent EV mode usage boosts MPGe; aggressive acceleration lowers it.
- Charge strategy: Regular top-ups help maintain a longer electric range for daily trips.
- Climate and accessories: Heating/cooling impacts battery efficiency and range.
In practice, many owners report real-world efficiency near the EPA estimates when charging regularly and using EV for shorter trips.
Charging and ownership considerations
Owners can recharge at home or public stations using Level 2 charging, which helps maximize the electric portion of the vehicle’s operation. The plug-in hybrid setup is designed to offer substantial electric range for daily commuting while preserving a gasoline engine for longer trips.
Ultimately, the 2024 RX 450h+ aims to balance the benefits of electric driving with the flexibility of a gasoline engine, which is reflected in its EPA efficiency numbers and its all-electric range.
Summary
The 2024 Lexus RX 450h+ is a plug-in hybrid SUV that delivers about 74 MPGe combined, up to roughly 38 miles on electricity, and around 29 mpg when running on gasoline alone. With practical all-electric range for daily commuting and the flexibility of a gasoline engine for longer trips, the RX 450h+ offers a balanced efficiency profile for buyers weighing fuel economy and versatility.
