Lexus RX 450h: 304 BHP Hybrid Luxury With 256.8 MPG Efficiency

The Lexus RX 450h stands out as a premium plug-in hybrid SUV that prioritizes serene driving, cutting-edge technology, and unwavering build quality. This model blends a potent powertrain with everyday usability, making it ideal for those seeking refinement over raw sportiness.

Powertrain and Performance Excellence

At the heart of the RX 450h lies a sophisticated 2.5-liter four-cylinder petrol engine paired with dual electric motors and an 18.1kWh battery, delivering a combined 304bhp. This setup propels the SUV from 0-62mph in 6.5 seconds, with a top speed of 124mph, while official economy figures reach an astonishing 256.8mpg and CO2 emissions as low as 24g/km.

The plug-in hybrid system enables up to 84mph on electric power alone, providing smooth, instantaneous torque perfect for urban commutes. The e-CVT automatic transmission and four-wheel drive enhance traction, though it favors relaxed cruising over aggressive acceleration. Throttle response can feel droney at high revs, rewarding gentle inputs with superior refinement.

Driving Dynamics and Ride Comfort

Lexus tunes the RX 450h for ultimate comfort, with suspension that absorbs road imperfections effortlessly. It’s whisper-quiet on highways, even at speed, thanks to excellent noise insulation and hybrid smoothness.

Handling is composed but not sporty; the large SUV body prioritizes stability over agility. Keen drivers may find it lacks excitement compared to rivals, but for long-distance wafting, it’s peerless. Electric four-wheel drive adds confidence in wet conditions without compromising efficiency.

Interior Luxury and Technology Highlights

The cabin exudes Lexus’s signature quality, with supple materials, precise assembly, and thoughtful touches like multiple storage cubbies. Top trims like Takumi include a panoramic roof, heated/ventilated seats, three-zone climate control, and a premium Mark Levinson sound system.

The infotainment system features a large touchscreen with wireless Apple CarPlay/Android Auto, intuitive touch controls, and a head-up display. An adjustable digital rear-view mirror proves innovative, though standard visibility suffices.

• Seating: Comfortable for five adults, with ample legroom and support.
• Climate: Tri-zone automatic with rear vents for passenger comfort.
• Tech: Wireless charging, 360-degree cameras, and adaptive cruise control standard on higher specs.

Practicality and Space Considerations

Despite its size, the RX 450h offers average practicality. Boot space is generous for five passengers, but no seven-seat option disappoints families. Rear seats fold flat for expanded cargo, yet rivals provide more versatility.

Daily usability shines with a power liftgate, rain-sensing wipers, and abundant cubbies. It’s spacious upfront and accommodates three adults rearward comfortably, though luggage capacity trails some competitors.

Trim Levels and Pricing Overview

Starting around £63,735, the RX 450h climbs to £85,400 for top specs. The mid-range Premium Plus Pack balances value with essentials like the panoramic roof and HUD. Takumi adds luxury flourishes for £79,450.

• Premium Plus: Panoramic roof, wireless charger, digital mirror.
• Takumi: Mark Levinson audio, ventilated seats, advanced safety suite.

The plug-in 450h+ is projected to dominate 55% of sales due to its efficiency edge over the self-charging 350h.

Safety and Reliability Strengths

Lexus equips the RX 450h with comprehensive safety tech, including pre-collision systems, lane tracing, and blind-spot monitoring. Its hybrid reliability is legendary, backed by strong warranties and low running costs.
