Lexus RX 450h running costs

The Lexus RX 450h makes the most sense as a company car

You don’t get a grant with a hybrid like the Lexus RX 450h, and the entry-level five-seat SE model costs a close to £49,000. You’ll pay around £2,000 more for the seven-seat 450h L version, and the top spec 450h L Premier costs around £62,000. That's not cheap, but considering the specification, it looks reasonable value compared to luxury SUV rivals.

The Lexus also benefits from advantageous Benefit-in-Kind (BiK) rates compared to non-hybrid rivals, which given the relatively high list prices could mean significant savings. The 450h has a BiK rate of 27%, whereas the Range Rover Sport attracts a 37% rate in entry-level petrol guise. The Lexus BiK benefits fade when you compare it with PHEV models, though; these can attract rates for company-car drivers as low as 9% in the case of the Volvo XC90 T8 Twin Engine.

Plug-in hybrid drivers can also take advantage of London Congestion Charge exemption, whereas the Lexus doesn’t qualify.

Lexus RX 450h insurance group

You’ll find the Lexus 450h quite pricey to insure, as it falls into group ratings 41 and 42 depending on spec. However, it’s not out of step with rivals, which are all in the same ballpark.

Warranty

The three-year/60,000-mile warranty that Lexus provides is unexceptional when others like BMW provide unlimited-mileage cover over three years, although the Japanese company’s gold-plated reputation for reliability should provide ample reassurance in its own right. The Lexus warranty extends to five years for the hybrid battery and other components, but there’s a 60,000-mile limit on those items, too.

Servicing

Lexus RX 450h servicing is due every 10,000 miles, at a cost of £295 for intermediate services (10,000, 30,000 and 50,000 miles) and £495 for full services (20,000 and 40,000 miles).

Road tax

All Lexus RX 450h models cost £130 in road tax, but as they all cost more than the £40,000 luxury-car threshold, you’ll be asked to stump up a £310 surcharge for years two to six. That means the annual road-tax bill in those years will be £440.

Depreciation

Our experts reckon Lexus RX 450h depreciation over three years and 36,000 miles will see residual values fall to between 56% and 50% of the original purchase price. The seven-seater models are at the bottom end of that range and the less expensive SE models at the top.
