Lexus IS 300h running costs

Good-value pricing and tax benefits make the Lexus IS 300h a solid company-car choice

Insurance group Warranty Service intervals 2019/20 company-car tax cost (20%/40%)

While the Lexus "self-charging hybrid" powertrain doesn’t offer all the advantages (or demand the compromises) of its plug-in hybrid rivals, it tends not to cost as much either. So while it may not have the best Benefit-in-Kind tax rate, chances are you’ll be paying a percentage of a smaller list price to the taxman than if you’d plumped for a PHEV. The Lexus also escapes the diesel surcharge on BiK, so its rate looks attractive against that of the BMW 320d.

Note also that the larger 18-inch wheels of Sport versions are enough to bump the BiK rate up due to slightly higher CO2 levels, and no IS 300h qualifies for London Congestion Charge exemption, as the cut-off figure is 75g/km of CO2.

Lexus IS 300h insurance group

The performance and cost of this Lexus means insurance will be fairly pricey. It comes in at insurance group ratings of between 28 and 29 depending on specification, but that’s in the same ballpark as its upmarket rivals from BMW and Mercedes.


The three-year/60,000-mile warranty provided by Lexus across its range is very much the industry standard, although as mentioned previously the hybrid components get an extra two years of cover.


You’ll need to plan a service annually or at increments of 15,000 miles to keep your warranty valid. The cost varies between £250 and £450 on an alternate year-by-year basis, although the 60,000-mile visit will cost £650.

Road tax

Most versions of the IS 300h incur £135 annual road tax, but beware models priced over the £40,000 mark, which attract a surcharge and will cost you £455 annually until year six. The same applies if you option-up a cheaper version and take the purchase price over £40,000.


We reckon the Lexus IS 300h will be worth between 45 and 48% of its new value after three years and 60,000 miles – more expensive versions doing slightly worse than more mainstream trim levels.
