BMW i4 M50 Review: Is This The Electric M Car For Proper Petrolheads?

Right then, let's get straight to the point. The big question looming over this electric beast is a simple one: is the BMW i4 M50 a proper M car? Or is it just a 4 Series Gran Coupé that’s been force-fed a battery pack, given a fancy badge, and sent out to fleece early adopters? We're here to give you the unvarnished truth, not just regurgitate some marketing guff from Munich.

Let's get one thing straight from the off: the numbers are utterly bonkers. With a staggering 544 bhp and 795 Nm of instant torque , this isn't just fast; it's bordering on antisocial. That 0-62mph sprint is dispatched in a ludicrous 3.9 seconds , putting it firmly in supercar-bothering territory. It's the sort of brutal, relentless acceleration that pins you to your seat and plasters a stupid grin across your face.

But as any proper enthusiast knows, an M car is about more than just straight-line speed. It’s about soul, feedback, and a certain lairy character that makes you want to take the long way home via every B-road you can find. The real test is whether BMW's M division has managed to inject that same magic into a two-and-a-bit-tonne electric saloon.

Here are the headline stats you need. Think of it as the Top Trumps card for the M50 before we dive into the nitty-gritty.

These are, by any measure, serious performance figures that demand respect. But the story doesn't end there.

The i4 M50 is based on the existing 4 Series Gran Coupé, which is both a blessing and a curse. On one hand, it looks like a normal, handsome car, avoiding the "look at me, I'm electric!" design language that puts so many people off. On the other, it feels less like a ground-up revolution and more like a very, very clever bodge.

This familiarity has clearly worked a charm, though. The BMW i4 M50 didn't just perform well in the UK; it became the best-selling M model globally for the third consecutive year . It spearheaded a record-breaking year for BMW M, which shifted 206,582 vehicles worldwide – a blend of blistering pace and modern efficiency that British buyers clearly can't get enough of.

The M50's success has positioned it as a serious challenger in the premium EV market. It’s forcing rivals to sit up and take notice, and it makes us reconsider what a performance car can be in this new electric age.

If you're keen to see how it stacks up against other absurdly quick EVs, check out our guide on the 7 fastest electric cars that'll rearrange your organs in 2025. For now, let’s dig into whether that raw performance translates to genuine driving pleasure on Britain’s less-than-perfect roads.

Right, let’s get down to brass tacks. Numbers on a spec sheet are one thing, but how does the BMW i4 M50 actually handle a greasy, pothole-riddled B-road on a damp Tuesday in Telford? What's the point of 544 bhp when you’re navigating craters that could swallow a small hatchback? This is where the M50 has to earn its badge.

The acceleration, frankly, is violent. In Sport Boost mode, planting your right foot delivers a gut-punch of instant torque that feels utterly relentless. It’s the kind of shove that makes your passengers gasp, then laugh hysterically. This isn’t just about winning traffic light grands prix; it’s about making overtakes on single-carriageway roads laughably easy. See a gap? A twitch of the ankle and you’re gone. It’s supercar pace, delivered with silent, brutal efficiency.

But straight-line speed is the easy bit for a powerful EV. The real question is, can it dance?

Let’s be honest, at 2,290 kg , this is a hefty machine. You feel that mass, but BMW's M division has pulled an absolute blinder with how they’ve managed it. The battery pack is slung low in the chassis, giving the car a centre of gravity lower than a 3 Series saloon. The result is a car that feels incredibly planted and stable.

This setup, combined with the standard adaptive M suspension and rear air springs, allows the M50 to strike a brilliant balance. In Comfort mode, it soaks up the worst of Britain’s road surfaces with a composure that belies its sporty intentions. It’s firm, yes, but it never crashes or jolts you about. It is, genuinely, a comfortable daily driver.

Flick it into Sport, however, and everything tightens up. The suspension firms, the steering gains weight, and the car hunkers down, ready for a proper thrashing. It’s here that the M division’s DNA begins to shine through. The steering is quick and direct, offering far more feedback than you’d get from many of its electric rivals.

Through a series of tight corners, the M50 remains astonishingly flat and composed. The all-wheel-drive system, with its rear-biased setup, provides immense traction, clawing you out of bends with an iron grip. It’s a hugely confidence-inspiring car to drive quickly, even when the weather is doing its best to be miserable.

Of course, you can’t escape its electric nature entirely. The regenerative braking is a key part of the experience. You can choose from several modes, but 'B' mode offers proper one-pedal driving. It’s brilliant around town but can feel a bit unnatural when you’re pressing on, interfering with the rhythm of a spirited drive. Thankfully, the Adaptive mode is a genius touch—it uses navigation data and sensors to adjust the regen level automatically, which works surprisingly well.

Then there’s the sound. BMW roped in film composer Hans Zimmer to create the "IconicSounds". It's a synthetic whirring hum that rises and falls with your throttle inputs. Some will love it, calling it futuristic; others will call it a pointless gimmick and switch it off immediately. The choice, thankfully, is yours.

Ultimately, the M50 pulls off a remarkable trick. It delivers the savage, organ-rearranging acceleration you expect from a top-tier EV, but marries it with a chassis that offers genuine poise, control, and, dare I say it, a bit of fun. It’s not a lightweight M2, but it proves that a heavy electric car can still put a massive grin on your face on a proper British road.

Right, let's get to the question that haunts every potential EV owner: what’s the actual range? BMW’s official brochure will tell you the i4 M50 can manage up to 318 miles on the WLTP cycle. And to that, we say, with a healthy dose of British scepticism, pull the other one.

That number was probably achieved by a featherweight test driver on a closed circuit, rolling downhill with a friendly tailwind after skipping breakfast. It’s pure lab-coat fantasy. What you really need to know is whether it’ll get you from Bristol to Newcastle on a single charge in the middle of winter without causing a full-blown panic attack.

The answer, thankfully, is a reassuring "very nearly".

Our road tests, which involve driving like a normal person with places to be and a slight impatience for middle-lane hoggers, paint a much more realistic picture.

On a mild summer's day, mixing motorway stints with a bit of A-road fun, you can genuinely expect to see around 260 to 280 miles . That’s plenty for most long trips and a very respectable figure for a car with this much poke.

But let's be honest, UK weather isn't always mild. Crank up the heating on a frosty January morning with the heated seats on full blast, and that range will inevitably take a hit. You'll be looking at something closer to 210-230 miles . It's a noticeable drop, for sure, but that's just the physics of batteries in the cold. The i4 M50 remains perfectly usable, and we explain the science behind this in our guide to electric car real-world range—the unvarnished truth.

What really matters here is efficiency. The i4 M50 consistently averages between 2.8 and 3.2 miles per kWh in real-world driving. For a two-tonne performance saloon that can embarrass sports cars, that's seriously impressive. It's this efficiency that gives it such a usable real-world range, making it a viable companion for both the daily grind and weekend getaways.

So, you’ve enjoyed the M50’s performance and run the battery down. Now for the next great EV adventure: finding a public charger that actually works. The good news is the i4 M50 is equipped for a quick top-up, with a peak charging speed of 205kW . In plain English, that's properly fast.

That’s just enough time to grab a grim service station coffee and a stale pastry before you’re ready to hit the road again. This kind of charging speed is what makes long-distance EV driving a breeze rather than a chore.

For day-to-day life, you’ll be charging at home on a 7kW wallbox . Just plug it in when you get home, and you’ll wake up with a full ‘tank’ every morning. On a cheap overnight electricity tariff, a full battery costs less than a pint in London, which makes the daily commute ridiculously cheap compared to feeding a petrol M-car’s habit. This is where the i4 M50 transforms from a weekend weapon into a surprisingly sensible daily driver.

Climb into the driver’s seat of the BMW i4 M50, and one thing hits you immediately: the screen. It's an immense, curved slab of glass that sweeps two-thirds of the way across the dashboard. BMW calls it the 'Curved Display', and it elegantly merges a 12.3-inch digital instrument cluster with a massive 14.9-inch central infotainment touchscreen. It’s a genuine showstopper, looking like it’s been lifted straight from a futuristic concept car.

But living with it day-to-day reveals a few cracks in the facade. For starters, it’s an absolute magnet for fingerprints and dust. More importantly, in the name of minimalism, BMW has binned most of the physical buttons. Need to change the cabin temperature or turn on the heated seats? That now requires a distracting prod and swipe through a menu. When you’re trying to quickly demist the windscreen on a dreary UK morning, it feels like a genuine step backwards.

It’s a classic case of form trumping function. The iDrive 8 operating system is snappy and feature-rich, no doubt about it. But burying core controls in sub-menus is a faff you just don’t need when you’re trying to focus on the road.

Look past the screen-fest, and the rest of the cabin is pure, modern BMW – which is to say, it’s excellent. The build quality is simply first-rate. Every switch clicks with precision, every surface you touch feels solid and expensive. It’s a tangible cut above some key rivals where plastics can feel a bit thin and hollow.

The standard-fit sports seats are brilliant. They hold you snugly in place when you’re enjoying a B-road, but remain perfectly comfortable for a long, dull slog up the M1. Better still, the driving position is spot-on: low, purposeful, and sporty. It’s a constant reminder that, despite the silent powertrain, this is a proper driver's car at heart.

This familiar, high-quality environment is a massive part of its appeal. It doesn't shout about its electric credentials; it just gets on with the business of being a comfortable, luxurious, and superbly put-together place to be.

This is where that sleek Gran Coupé body style starts to ask for a few compromises, particularly if you plan on carrying passengers.

• Rear Headroom: There’s no polite way to say this: it’s tight. Anyone nudging six feet tall will find their hair brushing against the headlining. It’s perfectly fine for kids or for short hops across town, but you wouldn’t want to stick your taller mates back there for a trip to Scotland.
• Legroom: It’s best described as adequate. Because the i4 is based on a platform shared with petrol and diesel cars, a chunky transmission tunnel still runs down the centre of the floor, robbing the middle passenger of any foot space. It’s really a four-seater in practice.
• Boot Space: Now for the good news. The huge hatchback boot opening is a massive advantage over a traditional saloon. You get a very useful 470 litres of space, which easily swallowed a couple of our large suitcases and some soft bags. Flip the rear seats down, and that expands to an impressive 1,290 litres , making it surprisingly versatile for those inevitable trips to the tip or IKEA.

So, where does that leave us? The i4 M50 absolutely nails the premium feel inside. The tech is visually stunning, even if the usability can be frustrating, and the quality is undeniable. While it’s not the roomiest car for those in the back, that practical hatchback boot gives it a dose of everyday usability that makes it a genuinely compelling performance car you can live with every single day.

Right, let's get down to it. The BMW i4 M50 doesn't exist in a vacuum. It’s been launched into a gladiatorial arena with some seriously capable electric rivals, most notably the Tesla Model 3 Performance and the Polestar 2. These aren't just cars; for many owners, they represent fiercely defended tribes.

So, where should your hard-earned money go? Is the premium feel and engineering pedigree of the BMW badge worth paying for when a Tesla gives you the keys to the world's most reliable charging network? This is the big question for UK buyers, and it's time for a proper, no-holds-barred comparison.

We're looking beyond the headline 0-62mph times. This is about what these cars are like to live with day-to-day: the genuine range you'll see on a cold Tuesday morning, the quality of the cabin you'll be sat in, and the price you'll have to justify.

You simply can’t talk about performance EVs without mentioning the Tesla Model 3 Performance. For years, it’s been the undisputed benchmark. It's quicker off the line than the BMW, with a blistering 0-60mph time of 3.1 seconds that remains utterly shocking every single time you experience it.

Its real trump card, though, is the Supercharger network. It's the EV equivalent of having your own private, flawlessly functioning petrol stations dotted across the country. It just works, every time.

But this is where the BMW fights back, and it fights back hard. Step inside the i4 M50 and it feels like a car from a different price league entirely. The materials are richer, the fit and finish is bank-vault solid, and it has that satisfyingly premium feel you expect from a German saloon. The Tesla’s minimalist cabin, by comparison, can feel a bit... sparse. And that’s being generous.

Then you have the Polestar 2, especially the dual-motor version with the optional Performance Pack. It’s the cool, understated choice. With its sharp, minimalist design and a cabin that feels both modern and impeccably screwed together, it offers a unique sense of rugged Scandi-cool that really sets it apart.

The Polestar is a fantastic bit of kit, but the BMW just edges it on pure driving dynamics. The M50 feels more agile and engaging when you’re really pushing on, its DNA feeling closer to that of a traditional sports saloon. While the Polestar is quick and capable, the BMW’s sheer sense of occasion and its ability to blend everyday comfort with outright lunacy gives it the nod for the keen driver.

As the data shows, while the sloping roofline does compromise rear headroom for taller passengers, its overall seating and surprisingly generous boot make it a very usable daily driver.

To put it all into perspective, here’s a head-to-head showdown comparing the i4 M50 with its closest rivals on the UK market, focusing on the stats that really matter.

Ultimately, your choice depends entirely on your priorities. Do you value the raw speed and seamless charging of the Tesla, the cool Scandi design of the Polestar, or the premium finish and rewarding driving experience of the BMW? Each one makes a compelling case, but for different reasons.

So, after all the driving, charging, and prodding of screens, it’s time to get to the point. Should you really part with your hard-earned cash for a BMW i4 M50? The answer, I’m afraid, is a classic case of "it depends".

Let's be blunt. If you're a proper petrolhead being dragged kicking and screaming into the electric age, this car might just be the perfect transition. It delivers that terrifying, silent shove of EV power in a package that looks, feels, and drives like a bona fide BMW sports saloon. It's a compromise, sure, but it’s quite possibly the best one on the market today.

BMW has absolutely nailed the fundamentals here. The interior quality is superb, the driving position is spot-on, and the chassis is so brilliantly sorted you often forget you’re lugging around a battery pack the size of a small sofa. This is a car for someone who still values handling, poise, and proper build quality over minimalist gimmicks.

The ideal i4 M50 owner is someone craving the thrill of an M-badged car without the eye-watering fuel bills and nagging eco-guilt. They want a car that feels special to sit in and is rewarding to hustle down a B-road, yet can still handle the Monday-to-Friday slog with quiet composure.

• You'll love it if: You appreciate exceptional build quality, a properly engaging driving experience, and a design that doesn't scream "look at me, I'm electric!"
• You should probably walk away if: Your top priority is the absolute fastest 0-60 time, you need loads of space for rear passengers, or the thought of not having the Tesla Supercharger network gives you anxiety.

This blend of performance and premium feel has clearly struck a chord with UK buyers. The i4 has shot to the top of BMW's electric sales charts, with an impressive 12,953 registrations last year—a massive 45% jump . This storming performance helped BMW grab a dominant 20.4% share of the premium EV market in the UK. You can read more about BMW's strong electric growth on their official press site.

It’s an immensely capable and deeply desirable machine that proves performance, quality, and electric power can live together in harmony. It isn’t perfect, but it might just be the most complete electric performance car you can buy today.

Got a couple of questions still lingering? Let's tackle the most common ones we hear to clear things up before you head to the dealership.

Ah, the big debate. The honest answer? Not in the traditional sense. It's an M Performance model , which sits a rung below a full-fat M car like the M3 or M4.

Think of it this way: it has the M badge and the genuinely shocking straight-line speed, but it’s not a stripped-back, track-focused machine. It’s M Division’s take on a ferociously fast electric GT – built for the road, not the Nürburgring.

This is where EVs trounce petrol cars. The final figure depends on your home electricity tariff, of course, but it’s incredibly cheap.

If you have an EV-friendly overnight tariff charging around 7.5p per kWh , filling the 80.7 kWh usable battery from empty will cost you just £6.05 . For the price of a fancy coffee, you get over 250 miles of real-world driving.

Yes, it looks like the M50 is set to be replaced. BMW has already indicated that an even more powerful i4 M60 is coming, which will likely push power closer to the 600 bhp mark. Expect a slightly quicker 0-62mph time and a few other tweaks. It's more of an evolution, but it's definitely on the horizon.
