BMW I4 vs Tesla Model Y

What's the difference?

If you’re intimidated by the electric future, don't be, because BMW’s i4 is just as good as any non-M sedan BMW offers right now.

The i4 delivers all the things you love about a 3 Series, engaging driving dynamics, a well-appointed interior and comfortable ride, but its all-electric powertrain means you’ll never have to stop at a servo again.

With a large battery on board, the i4 also serves up a decent driving range that should put anxiety-prone EV drivers at ease.

That is, of course, if you can get onboard with the looks.

The Model Y Long Range is the pick of the line-up thanks mainly to its ability to travel further on a full charge, but also the price is excellent. The styling is starting to date, especially compared to fresher rivals with intriguing designs. But the advantage to Tesla is its battery tech and the constant over-the-air updates which will continue to enhance this product long after you've bought it.

If the i4 looks familiar, that’s because it is based on the 4 Series Gran Coupe that entered showrooms last year.

This means a four-door liftback body style with a sloping roofline, athletic proportions and sizing close to the Tesla Model 3 and Polestar 2.

Let’s get it out of the way early and talk about the elephant in the room, the oversized front grille.

Say whatever you want about it, there’s no denying it gives the i4 a unique and head-turning look, and in my opinion, it’s not too bad.

In the flesh, it really isn’t as big as the press photos have made it out to be, and with the front numberplate to split it up, it does start to look a bit more like a traditional grille.

In profile, the 19-inch wheels fill out the arches well, and hide the massive brakes that add to the i4’s sporty appearance.

I particularly like the almost flush door handles that look futuristic, but aren’t as pretentious as those retractable handles you see on Teslas and Range Rovers.

Slim tail-lights and a chunky bumper inform the styling of the i4’s rear, but we’re really not a fan of a rear diffuser that keeps the exhaust cut-outs.

It makes sense on a model like the 4 Series Gran Coupe, but it just looks look rather odd on an all-electric model like the i4.

While the outside of the i4 might be all about that big grille, the inside is all about big screens, two of them in fact.

The instrumentation and multimedia screens dominate the experience inside, but BMW has also included physical buttons on the steering wheel and centre stack, as well as a rotary control knob, to make navigating the menus that much easier.

The connected screens differentiate the i4 from its 4 Series Gran Coupe relative, and make the cabin feel futuristic and befitting of the all-electric powertrain.

Overall, the i4’s styling might not be to everyone’s tastes, but BMW definitely gets credit for being bold in its aesthetic choices.

Would have been nice to see BMW’s designers go a bit further in differentiating the i4 from its 4 Series Gran Coupe cousin, but there's no denying the head-turning appeal of this all-electric sedan.

The Model Y is a mid-sized SUV, about 4.75 metres long and has an aerodynamic wedge shape similar to the one Toyota’s early Prius had, but with a smooth and flat styling Tesla twist.

The clean and featureless look made the Model Y appear futuristic and modern two years ago but now, with the arrival of other mid-sized electric rivals and their intriguing and attractive designs, the Tesla is starting to appear dated. 

There is a styling update coming to the Model Y, but it won’t be a completely new car, just a few tweaks to keep it looking current. But it won’t do much. I think the time is up on this design.

The cabin embraces minimalism with plenty of clean and smooth horizontal surfaces devoid of buttons or dials. Only the large central screen and the steering wheel exist on the dashboard and in my eyes compared to rival offerings the Model Y’s interior has quickly gone from cool to devoid of personality.

As a premium mid-sized sedan, the BMW i4 offers up enough storage and space for most, but keep in mind there are limitations.

From the driver’s seat, everything is well placed and the electronically adjustable seats offer plenty of adjustability to get comfy for long road trips.

Storage options include an central cubby, glove box, two cupholders and small door pockets that just about fit a bottle, but the design means it rattles around a little.

Speaking of fiddly, between this car, and the weird plastic cowl thing found in the Z4 and 1 Series, BMW needs to be called out for some of the most annoying wireless smartphone charger designs.

This one is tucked all the way under a retractable lid, and is barely wide enough to fit some flagship-sized phones.

However, we will give BMW huge props for its iDrive8 multimedia system, which is displayed on a huge 14.9-inch screen.

The menus are clear, concise and intuitive, while the software is buttery smooth and responsive. It feels snappier than some phones we’ve used in the past.

Credit too for not making all inputs touch, as there is a rotary control knob and voice command capability available.

In the second row, things are a little more cramped, but at 183cm tall I can fit in the outboard seats with tight headroom.

There’s enough leg and shoulder-room, too, and passengers can make use of the climate controls, USB-C charging ports and a fold-down-centre armrest with two cupholders.

Opening the boot reveals 470 litres of volume, but fold the rear seats down and that pace swells to 1290L.

Loading large and bulky items is made much easier thanks to the liftback design, and it’s important to note i4 buyers aren't penalised in terms of practicality as the i4 and 4 Series Gran Coupe share the same boot capacity.

However, the charging cables can get in the way, as there isn’t any dedicated space for them.

The charging point is also in an annoying spot, in the right-rear fender where the petrol cap would be.

It means that you always have to reverse into charging spots, and it can be tricky to manoeuvre the i4 into just the right position to get the charging cable to reach.

The Nissan Leaf's front centre charging port, or the dual charging ports available on the left and right fenders in the Audi e-tron or Porsche Taycan are preferable.

Electric SUVs have moved practicality to a level combustion-engine equivalents can’t compete with thanks to their front and back boots and (no transmission tunnel) flat floors maximising people and storage space. 

The Model Y is practical with a 117L front boot and a rear boot with 854L litres of cargo capacity, while the cabin has large door pockets, wireless phone charging and two cupholders up front and in the second row.

The Model Y comes as a five-seater only, but leg- and headroom in the second row is excellent and even at 189cm tall I can sit behind my driving position. 

Back seat passengers also have directional air vents and two USB ports for charging.

Cabin practicality could be better, though. The large centre console is unnecessary as it’s not covering a transmission and driveshaft. We’re seeing other brands such as Kia make use of this area as a storage space perfect for even large bags.

Locking and unlocking the Model Y is done with a key card that needs to be swiped against a sensor in the B-pillar. This worked sporadically for me and I felt like the action could scratch the pillar’s surface.

There’s a phone app which can also lock and unlock the Model Y. We downloaded it and found the functions useful, from seeing how much charge is in the battery, to opening the boot, tracking the location of the car and turning the climate control on to cool or heat the cabin before driving. 

Only the weather changes more than Tesla’s pricing, but the latest adjustment to the Model Y Long Range price had it listing for $72,900. That could easily change again so it might be best to check back at CarsGuide or Tesla’s website for any updates.

At almost $73K the Long Range sits in the middle of the Model Y line-up, above the $64K entry grade and below the $83K Performance.

The standard features list for on the Model Y Long Range is decent and includes LED headlights and 19-inch alloy wheels, there’s the fixed glass roof, synthetic leather upholstery, the 15-inch central touchscreen, power adjustable and heated front seats, a 13-speaker stereo, sat nav, wireless phone charging, dual-zone climate control with direction air-vents in the second row and a power tailgate.

Also standard is Tesla’s so-called 'Autopilot' which is an advanced form of adaptive cruise control which combines braking and steering.  

Anything missing? A sunshade for the glass roof would be good. You can buy aftermarket ones but really it should be built-in. There’s no rear climate control, either, nor ventilated seats.

But the one item that’s not here and should be is a head-up display because the location of the speedo on the central display isn't ideal for keeping your eyes forward and on the road.

So, the price is good but the features list could do with a boost. Really, though, the reason for picking the Long Range grade is because it can travel further on a full charge than any other Model Y. You can skip ahead to the Efficiency section if you’re busting to find out what the range is.  

As for rivals, there are way more now than there were when the Model Y first came to Australia a couple years ago. Back then it was really just the Hyundai Ioniq 5.

Now there’s the Kia EV6 and soon to arrive EV5, the Mustang Mach-E, the Subaru Solterra and its Toyota bZ4X twin, while the Polstar 4 is coming, too. 

If there’s one thing BMW knows how to do well, it’s building a sports sedan like no other. And that holds true for its EVs.

Powering this i4 eDrive40 is a single electric motor that produces 250kW/430Nm, which beats the outputs of even the 330i and 430i Gran Coupe.

With drive sent to the rear wheels, the i4 eDrive40 can accelerate from 0-100km/h in just 5.7 seconds, beating out the aforementioned 330i and 430i models.

For those that want a bit more pep, the top-spec M50 grade’s dual-motor set-up punches out 400kW/795Nm for a lightning quick 3.9s 0-100km/h run.

Compared with its petrol-powered 4 Series Gran Coupe counterpart, the i4 certainly puts up respectable figures, while offering more than a performance match for the Polestar 2 and Tesla Model 3.

The Model Y Long Range is all-wheel drive thanks to a motor powering the front wheels and another turning the rear ones.

Together the motors have a combined output of 378kW and 493Nm which is an enormous amount of power and torque for a family SUV like this and that means the 0-100km/h time is also a pretty quick 5.0 seconds.  

With an 84kWh battery the official range on this i4 eDrive40 is pegged at 590km when tested to WLTP standards.

However, when fully charged, our test car's range readout was around 390km.

But keep in mind EVs aren’t as effective in cold weather, and the mercury was showing only three degrees on most days during this freezing Irish winter.

Luckily then, BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

Using an 11kW AC charger however, will require 8.5 hours for a full charge.

In a week with the car, I averaged an energy consumption rating of 23.4kWh per 100km, almost matching the official figure of 22.2kWh/100km.

My driving included several long-distance trips on the freeway, however, an environment in which an electric vehicle does not excel.

Worth noting the heavier and more energy-hungry M50’s official driving range drops to 510km, but we’re yet to test its real-world figures.

The Model Y Long Range’s name suggests it's the version for those looking for the maximum distance they can travel on a full charge and it is the smart choice in the line-up. That said, the extra range isn’t all that much more than the other grades.

Tesla says the Long Range with its battery fully charged can travel up to 533km and has a combined cycle energy efficiency of 16.9kWh per 100km (WLPT).

A range of 533km is impressive but only 78km more than the entry-grade Model Y and just 19km more than the top-of-the-line Performance.

How accurate are Tesla fuel efficiency figures? Well, my own testing over a combination of all types of driving saw the trip computer report an average of 16.8kWh/100km.

Tesla says one of its 250kW Superchargers can add up to 275km of range in 15 minutes.

If you came here just to find out whether BMW has succeeded in transplanting its signature sports sedan characteristics into the all-electric i4, the answer is, yes.

The best thing I can say about the i4 is that, aside from the way power is delivered and the lack of engine and exhaust noise, it feels just like a 3 or a 4 Series.

Steering is sharp and responsive, throttle and brake inputs are immediate, making this rear-drive i4 a delight to drive enthusiastically.

The staggered Michelin Pilot Sport 4 tyres and massive brakes obviously help in this regard, and look, it’s not as sharp as the Porsche Taycan, still the sharpest electric vehicle we’ve driven to date, but the driving experience in this i4 is comparable to the excellent 3 Series.

But I’m not in love with the fake sound piped into the cabin when in 'Sport' mode. It sounds weirdly low-rent and I much prefer to accelerate to triple digit speeds in serene, near-silence.

Switch things up to 'Comfort' mode, and the i4 makes for a surprisingly relaxed drive.

The steering gets bit a looser and the adaptive dampers ease off a little, soaking up bumps and road imperfections with minimal affect to occupants.

Pair this with the nearly-silent electric powertrain, and well, our little one in the back seat has fallen asleep on more than one occasion in my time with the car

You can also adjust the level of regenerative braking in the i4 and operate it with one pedal like in the Nissan Leaf and Hyundai Ioniq 5.

This is a more efficient way to drive an EV as it forces you to look ahead and be careful with your throttle inputs.

One-pedal driving might not be for everyone, but it’s nice to have the option there.

CarsGuide hasn't been alone in criticising the Model Y’s overly firm suspension with potholes and bumps seeming to unsettle the vehicle easily.

But Tesla says it's updated the suspension to a more ‘comfortable’ tune and we had a chance to test it.

So, is it more comfortable now? Yes, but it could be better. There appears to be softer absorption in the suspension but anything other than small bumps are still prominent.

Body control remains a bit jelly-like in that there’s too much jiggling and leaning when driving normally, even on typical suburban roads.

At this price point we'd expect the ride to be more comfortable and settled. But this is unlikely to be a deal breaker for most people.

Otherwise, the Model Y drives like most electric cars with instant and quick acceleration, direct steering and it’s all done in silence which makes commuting far more pleasant than idling in the traffic with a petrol or diesel engine and a transmission constantly shifting from first to second and back.

And apart from not using petrol or diesel that's the appeal of electric cars; how easy they are to drive. 

What would make life even easier is a head-up display or driver’s instrument cluster because the current central screen set-up, which shows the speed in a fairly small size in the display's top right corner, is far from ideal.

There have been cases reported on Australian Tesla forums where displays have broken making the car illegal to operate and if this happens out of warranty the repair can be costly.

Be aware, too, that the 'Full Self-Driving' abilities of the Model Y are restricted in Australia. The law states that some autonomous tech can be used, such as adaptive cruise control with lane changing, but you must keep your hands on the wheel.  

The Model Y was given the maximum five-star ANCAP rating in 2022, scoring incredibly well for occupant protection for adults and children. The advanced tech on board includes AEB, lane keeping assistance and blind-spot warning.

Great all-round camera vision is offered by the Model Y, too, which is very much needed for rear vision given the back window's modest viewing aperture. 

For child seats there are three top tether anchor points and two ISOFIX mounts in the second row.

The Model Y doesn’t have a spare wheel, but there is a puncture repair kit.

Quick note about the lack of physical buttons. I found not having easy to access physical climate control dials distracting. Most of the car’s other functions are also housed in the media display and I feel this is a potential safety issue.

Like all BMWs sold in Australia, the i4 comes with a three-year/unlimited kilometre warranty with roadside assist over that period.

This falls short of the now-standard five-year assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus and Mercedes-Benz.

Scheduled servicing intervals for the i4 are every 20,000km/24 months, at least in overseas materials.

Australian intervals are yet to be confirmed, but BMW is offering service price plans covering four- and six-year periods in 'Basic' and 'Plus' forms.

The Basic plan for four and six years is set at $1240 and $1765 respectively, while the Plus package is $4805 and $5500.

When it comes to ownership the Tesla Model Y is covered by a four-year/80,000km warranty which falls short of the Hyundai Ioniq 5’s five-year, unlimited kilometre cover and Kia’s seven-year, unlimited km promise on the EV6.

As for the battery warranty, Tesla will cover it for eight years or 192,000km, which is better than Hyundai’s eight year 160,000km deal and seven years or 150,000km from Kia.

The Model Y has condition-based servicing, meaning it will tell you when it wants to go to a Tesla workshop.
