Best plug-in hybrid cars 2024 – best and worst PHEVs named

It's a case of 'better late than never' for this plug-in hybrid version of the Mazda MX-30. You see, the electric MX-30 doesn't rank among our favourite electric cars, being hampered by a short official range and fast depreciation. The R-EV looks to address the first of those problems directly, by using a tiny engine to act as a generator for its battery – allowing you to go further.

The R-EV is also more powerful than regular MX-30, with 168bhp rather than 143bhp – resulting in a lower 0-62mph sprint time of 9.1 seconds. 

As a cash buy, you'll pay less for the R-EV than you would for rivals including the DS 4 E-Tense and Kia Niro PHEV, and you should also benefit from lower running costs – although, as with most plug-in hybrids, you're unlikely to match the official economy figure of 283mpg unless you're able to plug the car in regularly.

Downsides? Well, the MX-30 shares the same space issues as its electric sibling, because there isn't much of it. And while its odd reverse-hinged rear doors add some visual drama of getting in and out, they can be tricky to use in narrow parking bays. 

At the time of writing, prices for the Mazda MX-30 R-EV start from £31,495.

“Pressing the brake pedal on the MX-30 R-EV requires a bit more pressure than the one in the DS 4 E-Tense, but I don't think that's a bad thing, because its more precise response makes it easier to bring the Mazda to a halt smoothly.” – Will Nightingale, Reviews Editor

With its official electric-only range of 80 miles, the Mercedes GLC 300e has one of the longest ranges of any plug-in hybrid on sale.

However, there’s more to the GLC 300e than just range. The system is very smooth and refined, while performance is brisk. And while the plug-in hybrid GLC doesn't handle with quite the same agility as regular models, but it still offers plenty of grip and composure, and the steering is accurate enough to let you place the GLC wherever you want it.

As with many other new Mercedes models, the GLC is offered with a shedload of tech, with an infotainment system that’s responsive and easy to navigate. The boot is also a good size, while rear space is better than in the rival Lexus NX. Overall, it’s a brilliant package that’s ideal for both company car drivers and families alike.

At the time of writing, prices for the Mercedes GLC 300e start from £58,710.

“With standard air suspension at the rear, the GLC does a fine job of soaking up bumps, plus it remains hushed even at motorway speeds” – Lawrence Cheung, New Cars Editor

Choice is the order of the day in the latest E-Class, because you can have it in petrol mild hybrid, petrol plug-in hybrid or even diesel forms. And that's before you get to the fully electric Mercedes EQE.

The E300e plug-in hybrid is our recommended choice, and gets a combined 328bhp from its 2.0-litre petrol engine and electric motor. In fact, it's currently the most potent E-Class you can buy, accelerating from 0-62mph in a hot hatch-rivalling 6.5 seconds.

As a luxury car counting the Audi A6 and BMW 5 Series among its key rivals, you'd expect the E-Class to be comfortable inside, and to be surrounded by premium materials. That's largely the case, although the E-Class' infotainment system is neither as slick nor as intuitive to operate as the 5 Series' iDrive setup. And while the interior is visually appealing, the materials aren't as plush as those used on the A6.

This sixth-generation E-Class is larger in every respect than its predecessor, and that means there's lots of head and leg room throughout, and while plug-in hybrid models lose some boot space compared with regular versions, there's still likely to be enough for your family's holiday luggage.

At the time of writing, prices for the Mercedes E-Class E300e start from £68,020.

“I like the E-Class' rear seats – the space is generous, and the seatbacks fold down in a handy 40/20/40 split, so you can load longer items with ease while still keeping space for a passenger or two.” – Neil Winn, Deputy Reviews Editor

Given that its models occupy three spaces on this list, you'd be right in assuming that Mercedes clearly knows a thing or two about building tempting plug-in hybrids. Indeed, this version of the C-Class shares many of the same positive attributes as its GLC and E-Class siblings, but crucially will cost you less to buy.

Plug-in hybrids tend to be less comfortable than their conventionally powered siblings, because the extra weight of the batteries requires a stiffer suspension set-up, but the C300e comes with rear air suspension as standard, which helps to solve this problem. 

In addition, being able to run on elecrtric power for up to 68 miles at a time – according to official figures – helps it to qualify for a super-low company car tax rating.

The C300e can be a relatively practical choice, too, with a boot that’s just as long and wide as that of the regular C-Class. And while interior build quality falls some way behind rivals such as the Audi A4 and BMW 3 Series, there’s no denying the visual wow factor.

At the time of writing, prices for the Mercedes C-Class C300e start from £52,025.

“It's easy to get comfortable inside the C-Class. All versions come with plenty of adjustment in the seat and steering wheel, while AMG Line Premium cars and above get electric seat adjustment – useful if, like me, you have a long commute.” – Stuart Milne, Digital Editor

Only a handful of plug-in hybrids can travel further on a charge than the BMW X5, which is particularly impressive given that it’s a big, luxurious SUV.

In fact, if you commute less than 30 miles each way to work, the 65-mile electric range of the X5 xDrive50e could mean you’ll not burn a drop of fuel. Keep the battery charged, and you could see the official figure of 235mpg, although we recorded 27mpg when driving with a flat battery. Most drivers should see fuel economy between those two extremes, and company car drivers will enjoy low tax bills regardless.

Like the rest of the X5 range, the plug-in hybrid is superb to drive, with comfortable yet sure-footed handling and responsive steering. Its trump card here is straight-line performance: it takes 4.8sec to accelerate from 0-62mph – fractionally faster than the Range Rover Sport.

Inside, the X5 – in any guise – is hard to fault. The quality is exceptional, and the tech is brilliant, easy to use and plentiful. It’s just a shame it’s not quite as practical as the Volvo XC90.

At the time of writing, prices for the BMW X5 xDrive50e start from £80,835.

“It's very efficient, but the X5 comes with very wide tyres as standard, and these generate a fair amount of road noise as you drive along. Thankfully, the X5's standard stereo speakers can drown the din out.” – Darren Moss, Deputy Digital Editor

The plug-in hybrid P300e is our favourite engine in the Range Rover Evoque. It's the fastest model in the range (0-62mph takes just 6.1sec) and is smooth around town yet punchy on the motorway. It combines a 1.5-litre three-cylinder petrol engine with an electric motor and 15kWh battery, and can officially travel up to 38 miles on electric-only power. 

As you’d expect from a car that bears the Range Rover name, the Evoque’s interior is beautifully finished, with most of the surfaces you touch regularly coated in high-end materials. The driving position is also spot on, giving you a great view out and placing you higher than in most rival SUVs. Lots of adjustment means that it's easy to get comfy, too.

The Evoque is also surprisingly spacious for its size, having more space for rear passengers than most other family SUVs, although the boot isn’t as big as you’ll find in the BMW X1 or Volvo XC40.

At the time of writing, prices for the Range Rover Evoque P300e start from £49,000.

“The Evoque is a good choice if you regularly need to fill every seat in your car – that's because its rearbench is nice and wide, meaning fitting three adults side by side is less of a squeeze than in most rivals.” – Doug Revolta, Head of Video

If you’re in the market for a relatively compact plug-in hybrid with a premium badge on its nose, we’d recommend taking a look at the Audi A3 40 TFSIe. 

As well as having a high-quality interior, the A3 impresses with an excellent driving position and a comfy ride. Yes, a Mercedes A-Class A250e has a slightly cheaper purchase price and a marginally better electric-only range – the A3 manages 25 miles in real-world driving – but it’s not as refined, it doesn’t handle as well and at times its ride is more fractious. 

The A3 is peppy, with a combined 201bhp from its 1.4-litre petrol engine and electric motor, resulting in a 0-62mph sprint time of 7.6sec.

Front-seat passengers will have nothing to complain about in the A3, and while six-feet passengers in the rear won't be sprawling in luxury, they will be comfortable – the Seat Leon and Skoda Octavia are both better bets if space is your top priority. The Octavia also has a bigger boot, though the A3's should take your weekly shop or a couple of suitcases without any trouble.

At the time of writing, prices for the Audi A3 40 TFSIe start from £36,400.

“There are two sides to every coin, so while you'll pay slightly more for the Audi A3 than you would for equivalent versions of the BMW 1 Series, it'll hold on to its value better over the years – meaning you'll get a bigger percentage of your money back when you come to sell it.” – Dan Jones, Reviewer

The latest Lexus NX is one of the most compelling reasons to go green that we've yet seen, with a long electric-only range that should not only slash your running costs, but also makes for tempting company car tax rates. 

This large SUV is good to drive, too, and has an interior that's hard to fault in any respect – indeed, it places you higher above the road than the rival Audi Q5, giving you a more commanding driving position. Plus, it’s a car your family will enjoy, because they’ll have more room to stretch out than they would in some rivals, and the boot will have no trouble swallowing your holiday luggage.

In short, Lexus has proved that driving an electrified car without accepting compromises need not be a fantasy.

At the time of writing, prices for the Lexus NX 450h+ start from £54,950.

“If you're the kind of driver who likes to make a quick getaway from traffic lights, then you'll appreciate the extra pulling power that the 450h+ has over lesser NX models – its 305bhp is enough to reach 60mph in 5.8 seconds, which is faster than the Mercedes GLC 300e could manage.” – Mark Pearson, Used Cars Editor

You’re probably familiar with the BMW 3 Series; it’s long had a reputation for being among the best executive cars you can buy, and these days, our preferred version is also a plug-in hybrid.

The 330e model combines an electric motor with a punchy yet smooth 2.0-litre petrol engine, for an official electric range of 37 miles – that could be enough to cover your daily commute without using a drop of fuel.

Elsewhere, the 330e is nearly as rewarding to drive as any 3 Series, with sharp handling and a firm, well-controlled ride. The interior, meanwhile, is classy, comfortable and exceptionally user-friendly. Indeed, BMW's infotainment system is easier to get along with than the touchscreen setups you'll find in the Audi A4 and Mercedes C-Class.

At the time of writing, prices for the BMW 3 Series 330e start from £46,985.

“Like a lot of plug-in hybrids, pushing down on the 330e's brake pedal activates a regenerative braking system which, to the uninitiated, can feel a bit odd. It's useful, though, and I found it more confidence-inspiring than the brakes of some rivals.” – George Hill, Staff Writer

There are lots of impressive facts and figures associated with the Hyundai Santa Fe plug-in hybrid. There's the 36 miles that it can officially cover before it needs to burn any fuel. Then there's the 173.7mpg and 37g/km of CO2 that it averaged in official tests. But perhaps the most significant number of all is seven, because it’s one of the few plug-in hybrids that can carry that many people.

Altermatively, you can fill its massive boot with luggage instead – in our tests, we fitted 10 carry-on suitcases inside, which is more than the rival Nissan X-Trail.

The Santa Fe also impresses for value, because you get so much equipment as standard. Even entry-level cars come with adaptive cruise control, heated leather seats and keyless entry.

Just be aware that an all-new Santa Fe is due to arrive in the UK very soon, and should offer an improved all-electric range.

At the time of writing, prices for the Hyundai Santa Fe 1.6 T-GDi plug-in hybrid 4WD start from £48,385.

“The third row of the Santa Fe is amazingly spacious relative to rivals, and no longer means that anyone relegated to the rearmost seats will feel like they've drawn the short straw.” – Claire Evans, Consumer Editor
