Toyota Yaris Hybrid running costs

Yaris hybrid running costs are no higher than petrol-engined versions

While claimed fuel economy of up to 76.3mpg is impressive, it should be remembered that you'll only realise this figure if you make enough short, slow journeys to make full use of the Yaris Hybrid's electric motor. That means it's more likely to save money for urban dwellers who frequently encounter heavy traffic than those who mainly drive on free-flowing country lanes.

There are definite advantages for company-car users, though. Relatively low CO2 emissions mean the Yaris Hybrid brings a lower Benefit-in-Kind (BiK) tax liability than most supermini rivals, especially those fuelled by diesel. The entry-level Active model produces 84g/km of CO2 for a 19% BiK rating, while versions higher up the range produce 96g/km and slot into the 20% bracket.

In comparison, the 1.0-litre petrol Yaris produces 106g/km for a 22% BiK bracket, while a similarly sized 84bhp Ford Fiesta 1.5-litre TDCi diesel produces 103g/km of CO2, but is penalised for non-compliance with Real Time Emissions 2 (RTE2) rules, placing it in the 25% BiK bracket.

Despite qualifying as an 'alternative-fuel' car, the Yaris Hybrid's CO2 emissions are still too high to qualify for exemption from London's Congestion Charge – the upper limit is 75g/km.

Toyota Yaris Hybrid insurance group

Every Toyota Yaris Hybrid occupies insurance group 8. That means the it's likely to be a little costlier to insure than the 1.0-litre petrol (groups 2 and 3), but slightly cheaper than the 1.5-litre petrol (groups 9 and 10).

This compares well with the Ford Fiesta, whose entry-level Style trim level starts in insurance group 2, with the economical 1.5-litre diesel rated in insurance group 8. It's always worth seeking an insurance quote before you make a decision to buy, though – personal circumstances can have a greater effect on costs than a car's insurance group rating.

Warranty

Every Toyota sold in the UK comes with a five-year/100,000-mile warranty, which almost matches the five-year/unlimited mileage warranty provided by Hyundai. There's also a three-year/unlimited-mileage warranty against paintwork faults and surface rust, and a 12-year/unlimited-mileage warranty against corrosion – both of which only apply in the case of a manufacturing defect.

You can extend the warranty of your Yaris by either 12 months/15,000 miles or 24 months/30,000 miles at a time. The duration of extended warranty available depends on the age of your car: it must be under 12 years old and have covered 100,000 miles or less at the time of warranty extension.

Servicing

Scheduled Toyota Yaris Hybrid servicing is no more frequent or costly than for any other Yaris, but its 10,000-mile intervals are more frequent than for some rivals.  Fortunately, interim services are relatively affordable, currently priced at £165, and a 'Full' service is only required every second year, at £295. The most expensive scheduled service is the £355 'Full+', which is first due at 60,000 miles.

Toyota can set up a service contract that covers up to three years (30,000 miles) of scheduled maintenance for a fixed price. There's also an 'essential care' programme for cars over five years old, with lower prices that aim to keep owners coming back to official Toyota workshops.

Road tax

While the regular petrol Toyota Yaris costs £140 a year to tax, hybrid models are classified as 'alternative-fuel' cars and attract a slightly lower £130 annual rate. The first year of vehicle excise duty (VED) is typically covered within the purchase price of a new car.

Depreciation

Residual values of between 31 and 34% are predicted across the Yaris hybrid range. That means after years' driving, your car could be worth as little as 31% of its original purchase price. That's put into perspective when you consider that you would have paid £1,300 more for it than an automatic petrol version.

That's a little lower than the 1.5 and 1.0-litre petrol models, which are rated at around 37 and 34% respectively. It's a disappointing figure compared to the latest Ford Fiesta range, too – most models there return 40% or more of their value after three years and some petrol versions manage 45%.

These depreciation predictions don't seem to be borne out by prices of approved used examples of the Toyota Yaris Hybrid, nor those offered for sale outside the Toyota network, where three-year-old cars with around 30,000 miles on the clock are usually advertised for over half the original price.
