Lexus RX450h L Premier 2018: Ultimate Luxury Hybrid Review

The Lexus RX450h L Premier stands out in the crowded premium SUV market as a sophisticated seven-seater that prioritizes comfort, refinement, and hybrid efficiency. This extended-wheelbase version of the popular RX model delivers ample space for families while maintaining the brand’s signature blend of Japanese craftsmanship and advanced technology. With its smooth hybrid powertrain and opulent interior, it appeals to buyers seeking a serene driving experience without compromising on practicality.

Design and Exterior Appeal

The exterior of the 2018 Lexus RX450h L Premier exudes elegance with its bold spindle grille, sharp LED headlights, and sculpted lines that give it a commanding road presence. The L variant features a slightly longer body to accommodate the third row, yet it retains the sleek profile of the standard RX. Available in premium paints like deep metallic blues, it coordinates seamlessly with hybrid badges, enhancing its upscale vibe.

Wheel options up to 20 inches add to the poised stance, while features like auto-dimming mirrors and a 360-degree camera improve everyday usability. The design strikes a balance between aggressive styling and aerodynamic efficiency, making it visually distinctive among rivals like the Audi Q7 or Volvo XC90.

Spacious and Versatile Interior

Step inside, and the cabin impresses with high-quality materials, including perforated semi-aniline leather, Sapele wood trim with aluminum inlays, and soft-touch surfaces throughout. The Premier trim elevates this with heated and ventilated front seats featuring power extenders and lumbar support, plus heated second-row captain’s chairs for optimal comfort on long trips.

The extended wheelbase provides genuine seven-seat capacity, with the third row suitable for adults on shorter journeys. Boot space starts at 495 liters with all seats up, expanding to 966 liters when the rear rows are folded—practical for family hauls. Visibility remains excellent thanks to slim pillars, large windows, and a high driving position, making it easy to maneuver in urban settings.

• Front seats: Cooled/heated with extenders for fatigue-free drives.
• Second row: Captain’s chairs with heating, ample legroom.
• Third row: Fold-flat for flexibility, accessible via sliding mechanisms.
• Storage: Multiple cubbies, though rear USB ports are absent.

Hybrid Powertrain Performance

At the heart is a 3.5-liter V6 petrol engine paired with two electric motors, producing 308 bhp for a 0-62 mph sprint in 8.0 seconds and a top speed of 112 mph. The hybrid system delivers seamless transitions between petrol and electric power, ensuring whisper-quiet operation at low speeds and refined acceleration.

Real-world economy shines: around-town figures exceed 45 mpg, while motorway runs average 35 mpg—outpacing many diesel rivals. Official stats claim 47.1 mpg and 138 g/km CO2, though tests vary based on conditions. Adaptive suspension in Premier spec absorbs bumps effectively, though it can feel wallowy during spirited drives.

Driving Dynamics and Ride Comfort

Comfort is the RX450h L’s forte, with a plush ride that soothes over imperfect roads. The suspension handles potholes with composure, and noise insulation creates a library-quiet cabin. Steering is light and accurate for parking, though less engaging than BMW counterparts—perfect for relaxed cruising.

Driven calmly, body motions are controlled, but push harder, and the soft setup reveals its limits with some roll and hesitant throttle response. All-wheel drive provides confident grip, and safety systems like Lexus Safety System+ add peace of mind with adaptive cruise, lane assist, and pre-collision braking.

Technology and Infotainment

The Premier pack loads up on tech: a large central screen displays navigation and apps, controlled via a touchpad that’s divisive—intuitive for some, fiddly for others. No Apple CarPlay or Android Auto is a notable omission, and rear USB lacks.

Standouts include the 15-speaker Mark Levinson audio system, delivering concert-hall clarity, plus a 360-view monitor, climate control, and auto lights/wipers. Ambient lighting and a panoramic roof option enhance the mood.

Safety and Reliability

Lexus’s reputation for bullet-proof reliability underpins the RX, backed by comprehensive warranties. Standard safety tech includes pedestrian detection, blind-spot monitoring, and traffic-sign recognition. Crash test ratings are strong, reflecting Toyota-group engineering excellence.

Ownership Costs and Pricing

Priced from £61,995 (as tested around £62,640), the Premier offers excellent value with minimal options needed. Low running costs from hybrid efficiency and high residuals make it economical long-term. Road tax and insurance are reasonable for the class.

Pros and Cons

• Pros: Luxurious cabin, smooth hybrid, family space, premium audio, reliability.
• Cons: Fiddly infotainment, no smartphone mirroring, soft handling.
