Electric dreams... to own: The most reliable hybrid and electric cars you can buy (and the problematic ones) revealed

They usually demand a premium over a comparable petrol or diesel equivalent, which is one of the hurdles slowing the uptake of low-emission cars right now. But with recent reports that Prime Minister Boris Johnson has been considering a scrappage scheme for EVs to help the automotive sector recover from its collapse at the hands of the coronavirus pandemic, there could be a fresh spark in interest in electrified models in coming months.  However, motorists will want to know which green cars they can count on - which is where What Car? The car magazine, which polls thousands of vehicle owners every year about life with their motors, has revealed which current pure electric and hybrid machines have the best reliability track records. It comes in the week that the government has confirmed that pure electric owners will be able to fit their cars with green number plates from this autumn - and potentially benefit from being able to park more freely in cities and use bus lanes. While these green plates will exclusively be for battery electric cars only, many drivers are considering a hybrid as a means of bridging the gap from petrol and diesel ownership to full-blown zero-emissions motoring.  Here's a countdown of the 10 most reliable electrified models you can buy right now - and the 3 with the lowest dependability ratings from owners... Electrified category: available as a plug-in hybrid and pure electric Price new: from £36,025 (£33,025 with Plug-In Car Grant for EVs only) Price used: from £12,000 (plug-in hybrid range extender version) When the i3 hit the market in 2013, it arguably moved the EV game forward. didn't get enough samples of each version to break it down into separate results, so lumped them in as one group. Some 16 per cent of owners said they had problems in the last year, with the engine the main area of concern on hybrid models. Drivers said that half of cars took more than a week to repair, but most were fixed for free as part of the Korean firm's seven-year warranty. The slick saloon, though expensive, was the first mainstream model to provide blistering pace but also an extended driving range. Like the Auris, the Corolla on sale in showrooms now is available as a petrol or hybrid - and it's built in Burnaston, Derbyshire. The drivetrain for the Auris Hybrid was like-for-like with the Prius - a 1.8-litre petrol engine producing 98bhp and aided by an 80bhp electric motor, with power delivered via a constantly variable automatic transmission (CVT). Sharing technology with its Japanese counterpart, the luxury manufacturers offers self-charging hybrid systems with its range of plush saloons and suave SUVs. This latest fourth generation car - sold since 2016 - is the best yet, with just 5 per cent of owners reporting back saying theirs had gone wrong in the last 12 months. Though a high dependability rating should help the Lexus against the likes of the Jaguar E-Pace, Mercedes-Benz GLA and Volvo XC40.  A 99.7 per cent score from drivers suggests it is pretty much fault free. Just 3 per cent of owners with one said they had to have an issue fixed last year, and the only problems were related to the electrical gremlins that were unrelated to the drivetrain.    What Car? With a 100 per cent reliability record, it should be an example to buyers that hybrids are just as dependable - if not more so - than petrol and diesel cars and despite the added complexity of, adding batteries and electric motors.  What might put potential buyers of is the dated technology in the CT, which has seen it fall behind more advanced rivals on the market.  Electrified category: Available only as a self-charging hybrid Price new: from £20,355 Price used: from £6,000 There are a few similarities between the Yaris Hybrid and the Lexus CT, which have tied at the top of the reliability electrified cars rankings. Both have untarnished records, with no breakdowns or repairs required, meaning a 100 per cent reliability score and no costs for owners. A new Yaris is due in 2020, which could see the relatively hefty price tag of these hybrid cars slip as dealers look to make room for new stock. While it might have the third lowest reliability score of any hybrid or electric reported on, a rating of 93.6 per cent is hardly a case of it being a lemon.  Only 13% had a problem, with the most common area being interior trim. Fortunately for their owners, all the cars reported with these issues were covered to be repaired for free, though around three-quarters were off the road for more than a week being fixed. It's was launched in 2013 and had for a time been available as a package where you could buy the car outright but lease the battery separately from the French maker. The first-generation came to the end of cycle last year and has since been replaced by a new version with a boosted range of up to 245 miles, according to the official figures, and a starting price of £26,495 (inclusive of the Plug-In Car Grant). Unfortunately, owners of the earlier model reported a high percentage of problems, including a lot of electrical gremlins. Other areas affected included the battery, brakes, interior trim and suspension, which has seen its reliability score slip to 82.3 per cent - the lowest of any electrified mainstream vehicle. *used prices based on lowest model advertised on Auto Trader on 18/06/2020 with fewer than 100,000 miles on the clock and not an insurance write off
