Introduction - 2026 Mercedes CLA
Mercedes-Benz is revolutionising its compact 'coupe-like saloon' - the CLA - by offering it in fully electric guise for the first time. Set to take on rivals like the Polestar 2, Tesla Model 3, BMW I4 and BYD Seal, the new, electric Mercedes CLA isn’t holding back on the specification.
The entry-level Mercedes CLA 250+ features rear-wheel drive with an 85kWh battery. Later models are set to get a smaller, 58kWh battery, with higher spec models gaining a 4Matic four-wheel drive with a decoupling front motor in the CLA 350 4Matic that's set to arrive in the UK later in 2026. A two-speed gearbox, 800V charging technology, intelligent brake regeneration, a multi-source heat pump and up to 320kW DC charging power is technology derived from Mercedes-Benz’s record-breaking Vision EQXX concept car.
Range, battery and charging
This CLA 250+ with EQ Technology has an 85 kWh battery feeding a 272hp electric motor on the back wheels. In the CLA it’s all about efficiency. As a result, the Merc has an official consumption figure of 5.7 miles per kWh – that’s better than most small electric hatchbacks! It means the Sport Edition version of the CLA has a range of 484 miles, which is enough for more than three weeks of driving for the average Brit. Compared to the obvious rivals, that’s a big deal. Even a long range Tesla Model 3 will conk out 48 miles before the Benz, although it has to be pointed out that the new, electric BMW 3 Series (okay, okay, the new BMW i3...) goes even further than the CLA.
As for real-world range, we saw 4.8 miles per kWh on mixed roads in mild conditions, which is good enough for more than 400 miles of range. And even during our wintery test drive in the UK we found that the new Merc CLA 250+ was really efficient - especially on the motorway where it lopes along, still returning some 320- to 350 miles of range.
If you do get half way up the country and want to charge, the Merc can accept up to 320 kW, which means you can boost the range by over 200 miles of range in just 10 minutes - provided you've got ideal charging conditions and are plugged into a rapid charger supporting 320kW, of course. And yes, that is faster charging than the Tesla Model 3, which is saying something.
From launch, the Mercedes did have one problem - it could only charge at 800V rapid points, and not the 400V units which make up a large number of rapid chargers in the UK (unless you used the converter that they provided, which is all a bit annoying). This was only a few months from the CLA's launch at the end of 2025, and it's now been remedied so that you can charge at any CCS-compatible public car charger - which is virtually of of them, by the way. Almost all EVs use a CCS socket for rapid charging, as it's the European standard, and is compatible with chargers all across the UK and Western Europe.
Practicality and boot space
Despite being a slinky, four-door coupe-saloon kinda thing, the electric Mercedes CLA gets a useful 405-litres of boot space, which is more than you get in the ID.3, for instance, but isn't quite as big as the boot in the Tesla Model 3. We've also driven the CLA Shooting Brake estate, which is a great option if you love the CLA but want a bigger boot. And there's also an SUV version coming if you need even more space.
As for the CLA saloon that I've been driving all around the UK? Again, think decent accommodation that'll take four normally-proportioned adults - but only just. That swoopy roof line hurts the headroom and I couldn’t recommend it for anyone taller than my 5 foot 8. or anyone shorter but with big hair... Anyone over 6ft will find it a squeeze, and the small rear door aperture can also be a bit tricky if you're really long-legged! Leaning in to deal with child seats could be a bit awkward, but it'd still be worth it to have such a lovely, plush family car.
At least there's loads of space up front, where it's really comfortable even for a tall driver. And if you do feel that you want something bigger but you still really like the feel and tech that Mercedes delivers, there's always the new, electric Merc C-Class and GLC.
Interior, design and technology
The interior of the Mercedes CLA is one of the really interesting things. You can really personalise the interior (which you certainly can't do with a Tesla or any other current executive car). There's about eight different seat finishes, and you can even choose from lots of different centre console finishes; there's a paper version with 'zen garden style' finish, or a wood finish, or pin stripes, or the aluminium finish of the car in our pictures is really lovely, too, if a bit more conventional.
And the screens? It's not three screens, it's the 'MBUX Hyperscreen'. To the rest of us, that means that there are three massive screens, plus optional head-up display. The two central screens are your main focus, and they've got built-in ChatGPT, it'll do intelligent route planning factoring in charging times, and it is all really clever. Mind you, that voice control... Well, check out the video to see how responsive it was!
Plus, there's games, movie streaming, games console connectivity and more - as well as the usual wireless Apple CarPlay and Android Auto. It's got everything you could ever think of wanting in your car. The fact that the interface is so much like a mobile phone is also good, as it is easy to use (and very configurable). Clever, eh?!
There are some irritations though - like Mercedes decided to copy the much-hated haptic buttons and switched windows from Volkswagen to save costs.
Motors, performance and handling
The electric CLA 250+ with EQ Technology gets a 272 hp electric motor on the back wheels, which is good for delivering a punchy 0-62mph time of 6.7 seconds. But the clever bit is that it also has a gearbox. Electric motors are usually so efficient that they don’t need one, as they are flexible enough to have instant power as you move off and still be spinning efficiently at motorway speeds. But the Mercedes hails from a country where they like to go really fast on the autobahns, so they’ve added another gear to make the electric motor more efficient at motorway speeds.
I know the Porsche Taycan has had the same for a few years, but that was mainly for the performance. In the CLA it’s more about efficiency. You don’t have to change gears yourself of course - the car decides when to switch gear, and you won't even notice it happening. You'll just notice that you're getting great efficiency and real-world range, and will feel extra smug about choosing the rather swanky CLA.
And it is just lovely to drive. My only niggle is that the throttle response can be a bit sharp in some of the drive modes, but I really like the CLA in Eco mode, which smoothes out that response and makes it even more efficient - yet still pretty rapid when you want it to be. More than that, the steering has a lovely weight and oily progression to it, and the ride comfort is very good. On bigger wheels it can feel a touch firm, but the damping is good enough to take the sting out of even the UK's coarse and broken roads. It feels very controlled, very precise and very serene.
While the others in this class are certainly great to drive, I'd say that the CLA is the best of the lot. There's also a dual-motor CLA 350+ version arriving soon, which I drove briefly out in Denmark on a European Car of the Year test drive, and it's just lovely to drive. Seriously rapid, surprisingly fun but also very confident.
Running costs and pricing
The electric CLA 250+ Sport Edition starts from under £46,000, and it's surprisingly well equipped. Standard kit includes that lovely pano roof, leatherette upholstery, parking camera and more – although the AMG Line, with its snazzier white-and-black interior, keyless entry and AMG alloys will likely be the more popular trim at just under £50,000. You can also step up to the top-spec car with its backlit grille and sportier styling, but I'd say that prices get a bit punchy at that sort of level.
Whichever model of the CLA you look at, pricing is very competitive, even next to alternatives like the Tesla Model 3, Polestar 2 and BYD Seal.
Verdict
The electric Mercedes CLA is the start of a new era of electric cars for Mercedes-Benz, and it looks to be a very good era indeed. I love that Mercedes has focussed on efficiency here, rather than simply squeezing in more battery for a bigger range, and that's shown in the real-world range as well as the claimed range. Not only that, but the CLA is just lovely to drive, even on our rubbish UK roads. The problem is that the rear passenger space is a bit disappointing, and I don't love all the plastics that you get around the dash.
Even so, the CLA is innovative, efficiency-enhancing technology. And that styling? Blimey, it's lovely, and really does feel like a much more premium prospect even than a Polestar 2 - never mind a Tesla Model 3. There are others in this class that cost less on monthly finance, and that have much better passenger space and more usable infotainment. But even so, the CLA is one of the best electric executive cars you can buy.
