The Lexus RX 450h is the hybrid version of the mid‑size RX SUV, combining a 3.5‑litre V6 with an electric system for strong yet efficient performance in a comfortable luxury crossover package. It suits buyers who want an S‑UV‑class cruiser with lower fuel consumption than a conventional V6 and more refinement than a pure EV‑only driver.

Five‑seat hybrid luxury SUV

The RX 450h is a five‑seat compact to mid‑size SUV, with a sleek, coupe‑like roofline and a tall greenhouse that gives good visibility and a premium feel. It is built on Lexus’ GA‑K platform and is available in both front‑wheel drive and AWD (often badged RX 450h F Sport AWD or RX 450h+ plug‑in‑hybrid in the latest generation). The boot is around 29–30 cubic feet (roughly 800–850 litres) behind the rear seats, which is generous for its class.

3.5‑litre V6 hybrid system

The RX 450h uses a 3.5‑litre V6 petrol engine paired with electric motors and a lithium‑ion or nickel‑metal‑hydride battery, giving a system output of about 300–309 hp depending on model year and market. Power is sent through an electronic continuously variable transmission (eCVT) to the front wheels, or to front and rear wheels via AWD systems on higher trims. The electric‑only mode helps with city driving and low‑speed manoeuvring, while the V6 kicks in for highway cruising and acceleration, giving 0–100 km/h in roughly 6.5–7.5 seconds.

Excellent fuel efficiency for a V6‑class SUV

The RX 450h is significantly more efficient than a standard V6‑powered RX, with real‑world consumption often around 5.5–6.5 L/100 km (roughly 14–18 km/l) on mixed driving, and EPA‑style ratings around 30–32 mpg (about 7.4–7.8 L/100 km) in the U.S. In the plug‑in RX 450h+ variant, you can drive up to about 60–69 km on pure electric power, after which the car reverts to conventional hybrid mode while still returning segment‑leading fuel economy.

Comfort‑oriented luxury and tech

Inside, the RX 450h focuses on comfort and refinement: soft leather or synthetic upholstery, heated/ventilated front seats, semi‑digital or full‑digital dash options, and a large central touchscreen with navigation, Apple CarPlay, Android Auto, and wireless charging on newer models. Higher trims add features such as head‑up display, panoramic sunroof, Mark Levinson audio, rear‑seat climate controls, and 360‑camera. Safety tech typically includes adaptive cruise, lane‑keeping, blind‑spot monitoring, rear‑cross‑traffic alert, automatic emergency braking, and multiple airbags.

Ideal for premium‑family and eco‑conscious buyers

The Lexus RX 450h suits families, professionals, and eco‑conscious luxury‑SUV buyers who want a comfortable, five‑seat crossover with strong performance, lower running costs than a V8, and a quiet, refined hybrid drive. It works well as a daily commuter, suburban family hauler, and long‑distance touring SUV, giving you a relaxed, tech‑laden Lexus experience with noticeably better fuel economy than a conventional petrol‑only RX.
