2025 BMW i4 xDrive40 review: This is the one most people will buy

Okay, not really relevant to the car being reviewed, but:

Can we just not? I DO live on a hill (~400'/122m) somewhere that DOES get a lot of winters, and I'm just fine with my RWD car on winter tires. Hell, both daughters have happily driven up/down the hill in a FWD Mini with all-seasons, occasionally laughing at spun-out AWD/4WD vehicles as they go.

(Edit: To clarify my point, I'm referring to most of the AWD cars out there that would do just as well with 2WD and a decent set of winter tires as they don't have the ground clearance to handle situations where you objectively probably need 4WD/AWD.)

More relevantly, as someone who's owned a ton of BMWs over the years and hasn't been a fan of all of their design decisions, I think they finally lost me when they moved to the new-design kidneys. It sort-of works on the SAVs but just looks too "basking shark chic" on a coupe/sedan.
I've driven tens of thousands of miles with a RWD drive BMW and good winter tires. Never had issue.

Summer tires and AWD are just dangerous so you have to run at least all season anyway, or go really slow. Even on dry pavement summer tires have significantly reduced grip at low temperatures.
Nice thing is that all seasons have gotten really good. I've been watching the Tyre Reviews channel and they do subjective and objective tests. The best all seasons like Michelins Crossclimate 2 are now almost as good as their reference winter tire. This includes stuff like traction, braking, and handling on both snow and ice.

It isn't like the Prius is designed to scrunch passengers next to the door on every turn. The stock tires actually work just fine when you are driving like a normal person and I rather trust the Toyota engineers a bit more than random internet posters. I've driven the thing in Colorado mountain winters for 4 years now. No problemo.
If they are stock, they are either all season or grand touring all season with compounds for better mileage and they are very skinny relative to most tires so you are dealing with all seasons.

I’m a year in to life with an i4 M50, it’s an excellent car. The fact it’s an EV honestly just fades into the background day to day, other than the refinement and instant throttle response.

It’s so heavy that when you’re really driving it, it feels more like a freakishly responsive and flat cornering X5 than a car. Not so great.

I suspect the RWD 40 would still be the better choice overall as it’s significantly lighter and more efficient too. In my case the lease rates actually made the M50 cheaper and I don’t regret my choice. xDrive 40 sounds like a nice halfway house for those who really want 4WD.

Yes, I was specifically calling out summer tires, not all seasons as the poster was commenting people don't want to deal with winter tires or all season tires.

Our van has Blizzaks but my commuter car has 3 season Comp 2 T/A with work fine up to 4 inches of snow. Most of the time the roads are clear so the all seasons work fine. If it is bad, I stay home or take the van if I need to be somewhere.

It should be notes that all season tires are not the same thing as all weather tires (which carry the 3 mountain peak symbol). The Michelin Crossclimate 2 tires (which I have on my Subaru, and which are awesome!) are all weather tires. If you want good snow performance and don't want to have to put on/take off winter tires every year, skip the all season tires and go with a good set of all weather tires.

The winter has been relatively mild as a result of climate change,

This probably needs more words to be unimpeachable. "The winter has been relatively mild due to some combination of climate change and good luck," for example.

Like, you might have had that mild winter if industrial civilization had never happened, it just would have been less likely.

Just caught this -

Summer tires, in the winter, are outright dangerous at low temps and you'll absolutely destroy the tread compound if you do it.

I had a set of Nitto NT555s on my old Corvette and drove them in below freezing temps once (which was a handful to say the least, even in the dry). They went from being awesome grippy tires to being greasy messes even in hot weather and were unpredictable as all hell.

IIRC manufacturers will void any treadwear warranty if you drive summer tires under 40* F too.

Don't do it.

Man, that rear view is terrible in that display. I think even a fish would have a problem with that fisheye view! The 360 "overhead" view makes it look like you are trying to park next to a long white RV, and everything around it is distorted in a funhouse-mirror way. What looks like a Toyota Solara behind you looks like it got miniaturized and stuck between two gargantuan SUVs. Surely something is wrong there.

The throttle response is instantaneous, and the brakes aren't grabby. It's quiet and smooth and rides well over bumps and potholes—a consequence of having to damp a 5,000 lb (2,200 kg) curb weight.
Sigh. Would like to see an understanding for why it is more than 1100 pounds more than the comparable 440i. Is the battery really 1200+ pounds? I would think the removal of the B58 (300 pounds on its own) and other ICE-specific components would save something meaningful but perhaps not?

At least it's not "induction cooktop chic."

I find it amusing that both big German luxury manufacturers lost the plot on the front end, but in opposite directions. A Mercedes-Benz still does not look right without the giant signature dictator's state car grille and hood ornament that they ditched around the turn of the millennium.

You'd think that going electric might give both companies' designers the opportunity to wipe the slate clean and produce something less hideous. It's not like either would lose any brand recognition in the process.

At least with a combustion engine there's a certain perverse "I slaved over a hot drafting table for nine months to make a car this ugly while still accommodating the cooling system's engineering demands," but without those constraints it just feels like the work of an excitable third grader with a sticker book.

5,000 lb curb weight, ~260 miles range out of >80kwh usable, 205kw max charging, 5.1s to 62mph.

Those are not really class leading stats for an EV in 2025; weight and acceleration in particular are pretty bad for a BMW.

Would love for somebody that actually understands the trade-offs of these 'combined designs' to weigh in on how much that is a factor in the not-so-great stats.

I would say the agnostic platform that the i4, i5, i7 share with their ICE counterparts with 100% why they are heavier than other BEVS, [and German luxury have always been on heavy side]

They already have all normal crash structure and bracing under the hood, plus extra skid plats and bracing for front and rear motors. and battery. then more bracing for the extra weight.

Its was a price BMW was willing to pay to save money on a ground up development of a BEV. (ie VW)

With the benefit of not dividing customers with a separate design language for ICE and BEV ( ie Mercedes)

and Its seems to be working for BMW. Despite some less than specs they are largely viewed as normal BMW's but just electric.
and BMW is leading in number of different BEV models and percentage of Plug in sales vs total sales.

All of these comments are insanity. Number of driven wheels, tire selection, car weight, driving care etc all play a factor. None of them are more important than others. AWD is pointless until you're in a ditch. All cars have All Wheel Brakes. All tires are equally terrible if you drive like a moron. If you think any of those factors will make you invincible, please visit your nearest ski resort on a snowstorm day, you'll find all the ditched subarus with their winter tires because they think they can drive like morons because they have AWD and good winter tires.

If you're going to force me to have a stupid dash screen you could at least put it in Portrait orientation instead of landscape or, worse, ultrawide landscape.
Funny how tastes differ. I hate portrait screens in cars with a passion. Especially ones that look like someone just glued a tablet to the console. The i4 screen is beautiful in comparison, plenty bright even in direct sunlight, and the software is top notch. You can set up the HUD, "instrument panel" and main screen to display all sorts of combinations of information, and control most things on the main screen via either touch or the dial.

Just wanted to give an extra thanks for the different wheel size and EPA range/estimate! Giant wheels (19" +) from the factory seems to be the norm, but I like the single motor with 18" wheels range better.
Unfortunate that they've decided on touchscreen climate controls. (Curious to know how long they last compared to physical switches?!)
Btw you can also set climate controls via voice commands. I rarely do as I usually just set the AC to auto on the lowest setting to keep the fan noise to a minimum, but it's one of the few things besides making phone calls that I think make sense having voice recognition for.

With warranty, sure. Outside that, unless you are comfortable wrenching on it yourself, I would never recommend someone buys a European lux vehicle out of warranty. Specifically, the i4 has air suspension in the rear. A VERY costly fix.
Like any car, if you have a good mechanic you trust, BMWs are fine to own. Reliability for them has come a long way, and as long as you weren’t taking them to the dealer for service, the older ones weren’t that expensive to maintain, either.

BEVs are better than combustion​


Hard disagree. BEVs are necessary, but they are not better outside of a few metrics.
Define "better".

In quality, livespan, service costs, fuel costs, insurance costs, etc., or just "for the environment"?

"Better" applies to nothing unless properly defined.

Agreed it would be more practical and look better, but we seem to be the minority there, and it would also likely be a significant drag on range - it would be nice to have the option, though.

For how well the electric i4s have been reviewed, I was a little surprised at used prices - 1-year-old examples with fewer than 10,000 miles are going for $20k under new MSRP around here. Which makes me hopeful when it's time to replace my current car in a couple years, but also wondering if they've had significant reliability issues.
For me, just bought another car due to a set of issues that pushed it as the right decision now, and it was gas. A couple of years from now with standardized NACS, it would have been a BEV.

According to Electric on the i4talk forums it actually is. "Battery: The whole unit weights 550 kg. 1212,5 lbs".

I didn't go as far as to verify what he said, after all fact checking is now banned so we just have to trust this internet bro.

Wow, overreact much? I wasn't saying AWD/4WD was useless or unnecessary (we have one of each),
lol, no, I’m not overreacting, and yes, you sure were saying exactly that. You popped off with an opinion with zero nuance and a shitload of generalizing, you were expecting a bunch of pats on the back and yeah buddy, glad to disappoint, stop being a fuckin’ know it all.

Bro, just about all infotainment screens, regardless of orientation, look like they were hot glued to the dash. There's two reasons I prefer portrait over landscape. 1) It's better for maps, because I want to see further in front of me on the map. Landscape is better at showing more of what's to the left and right, which I don't give a shit about. I've tried both orientations, portrait is better. 2) It's easier to package the screen lower in the dash without blocking air vents. This also helps to make the screen look more integrated into the system instead of looking like some hot-glue action.

All that said, I would happily chuck this and every single other infotainment system I've ever used, observed, or read about in the fuck-it bucket if I could just have a good spot to dock my phone in it's place for maps and tunes in either orientation I want. My phone is better at both things, and those are the only two reasons I have for having a screen in the first place.

Depends on what goes bad. Pulling a cylinder head is going to cost a small fortune, and apparently machine shops for valve jobs are few and far between. $8k for a new one. The quote for repairing my 535 was 12-18k, with a used engine, no warranty. Engine cost alone was about 6-7k for a like mileage one. New engine was worth more than the car. I managed to address the immediate problem and traded it in, rather than address the core issue causing the misdiagnosed failure I experienced: compression failure in a cylinder, debris in a couple of cylinders - thought initially a piston had disintegrated - this actually is a potential failure mode in the N55 engine as the stock pistons are cast. Instead massive carbon buildup on a single valve that broke free and was burnt onto the valve during multiple misfires. Note - good bore scope is worth its weight in gold.

That doesn't include all the other little parts that need replacing on a 100k mile car at that point, if you're going that far anyways.

So - if nothing major goes wrong (see about serpentine belts getting sucked into the engine for nightmares) it's not too bad. But "cheap" and "BMW" after 100k don't fit on the same page. They're not like Toyotas that make 150-200k before needing that type of attention normally. (v8 4Runners being an exception with the emissions exhaust valve failures at 100-120k, with a repair cost north of $3k, or a twisty wire IIRC)

I've had a number of vehicles between 100k and 200k, and at some point they all need a repair that's more than the car's worth, even if you're doing it yourself. That's trade in time, provided you catch it before catastrophic failures.

For what it's worth - I've had 2 BMWs go past 130k, and this one at almost 100k. The previous two were sold because reliability was a concern when both owned cars far exceed 100k.

That's nice. You live on a small hill at low elevation. I live in Colorado, and regularly drive at altitudes around 6200-10,000ft, where an average winter can bring not only ice but also deep snow, extended driving on steep grades, and extremely rapid shifts in conditions and temperatures. It can also, as is currently the case, bring 65-70F temperatures that result in dedicated winter tires crumbling like pencil erasers. In the conditions I am used to in my particular situation, an AWD car with 3-Peak rated all season tires is often a more capable and appropriate vehicle than anything with dedicated winter tires and 2WD. And that's how I've equipped my primary vehicle.

So, my friend, can you just not? By all means do what makes sense for you in your context, but do recognize that your circumstances are not universal, and maybe stop being a goddamn know-it-all.
So how well would the low ground clearance i4 function in your locations with 4wd? Yeah, thought so.

Wrong.

3pmsf is a pretty weak acceleration test on snow that most modern all seasons can clear.

Using the 3pmsf as a benchmark and saying it's more capable than dedicated winter tire on 2wd will be false in most situations.

If you have an excellent all-weather tire like the Michelin CC2s it might be true, however handling and breaking gets little help from 4wd in most daily driving.

This doesn't contribute much but I really wish someone would take away BMW's keyboards in the Car Naming Department. "i4 xDrive40?" Has anyone even tried to say this out loud, much less describe it to someone else with a straight face? This is far from the most egregious offense, too.

How about i40x? 440xi? Perfect, no, but they don't look like a robot having a stroke at a spelling bee, either.
People would usually just say "i4". The rest denotes the type of drivetrain, where the "xDrive" denotes BMW all wheel drive (it is a smart , computer-controlled wheel distributor of the torque across all wheels), and the remaining numbers are the engine/power of the vehicle. It is there to describe the full model, but in the end no one uses it. So it is barely a problem when you own one of this vehicles. Many people would also just say "white BMW" or so.

Unlike many posters here, I absolutely love the look of this car in person. It's honestly probably my favorite looking car right now, although I also continue to have a soft spot for the Model S (purely in terms of looks).

It's a shame with the transmission tunnel. It really makes the rear seats feel more cramped, even when you don't stuff a third person back there (which I would need to, but I realize I'm very much in the minority there). The Polestar suffers from the same thing.

I'm not sure how final the Neue Klasse designs are, but I have to admit I much prefer the i4 design over the new renders from BMW.

As someone who has driven a lot of EVs I can honestly say BMW makes the best ones, imo.
No snark, I would appreciate if you could expand upon this assertion.

I'm actually going to be in the market for a new car within the year and, until now, I've never been in a position to even consider a BMW. What makes them the best EVs in your opinion?

I'd never heard about a failure like a serpentine belt getting, literally, sucked into an engine before. I can't imagine the work that goes into fixing that, if it's even possible. It would seem like just a whole new engine would be needed...

Returning to the point though, no ICE means no need for belts, oil, which means much less in terms of normal maintenance that needs done. Do we have enough data on BMW EVs to get a sense of maintenance costs for them? Or at this point do we have a sense of common points of failure at high mileage?
