BMW I4 vs Tesla Model 3

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 3 Performance is one of those cars that’s undeniably impressive in almost every way, and hugely fast in absolutely every way, and yet can somehow still leave you feeling slightly cold. Or at least damp with fear sweat.

It’s not my kind of sports car, but if you love speed, and EVs, and Tesla, you’re gong to think it’s the Queen Bee’s knees.

Publishers: Please place the following in BOLD after the verdict:

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.

Tesla’s design folks waxed long and loud about how they’d finally been able to visually lift and separate this Performance Model 3 from the basic one and they point to the new front and rear fascias, more aggressive styling, aerodynamic flicks, integrated cooling ducts, rear diffuser and carbon-fibre spoiler, which are there not only to look good, but to to “optimise lift balance and high-speed stability”.

Now, I’ll grant you it’s better than a normal Model 3, and that we were regularly approached by excited Tesla fans asking “is this the NEW PERFORMANCE OH MY GOD I WANT ONE NOW?!?"

But honestly, I still think it’s a bit subtle, and that includes the strange little 'Performance' sticker/badge on the rear, which does look a lot like the Ludicrous symbol that Elon loves, from the awful movie Spaceballs, but Tesla staff insist it’s not, nor is it Plaid. 

Clearly, the design tweaks are there for a reason, and train spotters will note the differences immediately, but it’s still just not the most exciting car to look at, nor is it anywhere near as exciting to behold as it is to drive.

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.

Inside, the big news is the new seats. Tesla was happy to admit the pews fitted to the previous Performance just weren’t up to the job of holding humans in place when applying so much G force. 

The new 'Sport Seats' feature enhanced side cushioning and side bolsters for better lateral support during dynamic driving. And they can also be heated and ventilated. 

Elsewhere, there’s some carbon-fibre trim on top of the dash, with a Tesla-first weave pattern to further help the Performance stand out within the Model 3 line-up.

Other than that, it’s pretty standard Tesla sedan, which will be familiar if you’ve ever caught an Uber in Los Angeles. Spartan, minimalist, slightly cheap-feeling.

As for the practicality of the tech, I'm still against the giant 15-inch tablet-style touchscreen, for everything, the replacement of an indicator stalk with buttons and not having a speedo right in front of your eyes, where you need it.

Tesla says the price for the Model 3 Performance will be "starting at" $80,900, plus on-road costs. There's no word on whether there will be different spec levels and the company does not like answering questions or providing information.

What we also know about Tesla is that the price quoted could move down, or up, at any time, quite randomly, so if phrases like "residual value" or "depreciation" are of interest to you, it can be a challenging brand.

That side swipe aside, this sounds like astonishingly good value for this much performance from your Model 3 Performance. A Hyundai Ioniq 5 N would give it run for fun and involvement, if not brand fans, but it's $111,000, while a Porsche Taycan kicks off at $164,000 (it is a lot more car for the money, but it might struggle to keep up with this Tesla, at least in base model form).

In terms of equipment, it's pretty much standard Model 3 fare, other than the fast bits and a spot of carbon here and there.

You get 'Autopilot' included, of course, but you can't use all of its 'Full Self Driving functionality' on Australian roads. Not yet, anyway.

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.

If you’ve ever driven the previous Model 3 Performance you’ll know that it could well have come with Space X badging (arguably Elon’s more impressive engineering achievement), because it really did thrust rather than accelerate.

But this time the engineers wanted to go all out. Customers appreciated the incremental performance they got from the last Model 3 Performance version, but they told Tesla they wanted more.

With many enthusiasts among Tesla's engineering and development team, they looked to unlock the performance potential of the platform.

So, that meant a whole lot more madness and torque thump. It comes from a new Performance 4DU, an all-new drive unit - featuring an entirely new rear motor that uses bar-winding technology - unlocking 22 per cent more continuous power, 32 per cent more peak power and 16 per cent higher peak torque delivery. 

Overall figures are 380kW and 740Nm, but looking at them written down, they seem big, yet not as big as they feel in this car, as it’s shoving you from a standing start to 100km/h in three seconds flat. 

It feels faster. Sick-making fast, even.

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.

Despite being heavier and gruntier, Tesla claims the new Performance Model 3 manages to be more efficient than the one it replaces, albeit delivering just a two per cent reduction in energy consumption. Claimed energy usage is 16.7 kWh/100km.

Tesla claims a total range of 528km on the WLTP, which is obviously going to drop if you drive it the way its makers clearly intended.

Using a Tesla Supercharger, you can add 228km in 15 minutes and... that's all Tesla will tell us. There are no official figures available for how long a full charge takes, on either a Tesla charge or a home wallbox of your own.

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.

Very occasionally, one drives a car that makes the human body feel inadequate to the task. I would have worried that I’m getting old, that my body is simply too flubby and my brain too broken, to cope with the kind of wild acceleration and brutal g-forces the Model 3 Performance delivers.

But, fortunately, I had a videographer in the passenger seat, a much younger man who loves fast cars, and he kept threatening to vomit when I drove it hard, too. 

I’ve driven quite a few cars that you can use make your passenger sick, or hurt their necks - one obvious competitor in the shape of a Porsche Taycan Turbo S comes to mind - but it’s very rare that a vehicle is so intense it can make you, the driver, feel bilious.

Yes, you do bring this on yourself, by choosing to push this Performance anywhere near its limits through particularly sharp and intestine-shaped roads like the canyons outside Malibu Tesla chose to launch it on. 

On longer, sweeping bends it was far more of a joy, and less physically punishing, but in the tight stuff it often felt like corners were being thrown at you, as if you were driving behind the Millennium Falcon and being pulled along in its wake.

The brakes, special new sporting ones with track-ready pads, were up to the task, even though it often felt like they couldn’t possibly pull you up from the speeds you were doing.

And yes, it was entirely my fault that the very first time I even gently prodded the throttle and it launched me ahead past a California Highway Patrol officer, that was my fault too. Three minutes into the drive, holding an American fine, I had already deduced that perhaps this car was too fast for my own good.

But lots of EVs are fast in a straight line, you’re really comparing the length and depth of your “oooophhh” sounds at this point, but where this one succeeds is by being a lot better in the handling and ride and cornering departments than most.

Tesla’s stated goal with this car was to move beyond straight-line speed, to become more than a one-trick pony, and to do that it’s given the Performance a stiffer structure overall and updated the springs and stabiliser bars. 

Aerodynamic changes have reduced drag by five per cent, delivered a 36 per cent lift reduction, and a 55 per cent improvement in front-to-rear lift balance.

Tesla’s own, in-house version of adaptive dampers, not an option but included in every Performance, work with the car’s 'Vehicle Dynamics Controller' through its various modes - 'Insane' and 'Track' being the most… ludicrous - to immediately respond to driver inputs. 

The Performance rides well on LA’s awful concrete freeways but feels absolutely nailed down when you attack even a bumpy driver’s road.

This version also has a lot more power going to the rear wheels, to help it feel more sports-car playful and to fire out of bends the way an enthusiast’s car should. And make no mistake, I met them, the people behind this car are serious driving enthusiasts (although they demur, slightly, on whether their boss is one).

Track mode will allow some serious adjustability, drifting ability and fun, so the kind of people who want to hurl around a racing circuit in silence will love it.

Perhaps the only let downs are that it still feels a bit austere inside, just not very special, and that the steering is just a bit digital, soft and uninvolving, compared to the cars they clearly benchmarked against - BMWs and Porsches. 

Tesla provided no information about safety for the Performance Model but it is assumed it will be unchanged from a standard Model 3.

Aside from Autopilot that means auto emergency braking, lane keep aids, and instead of blind-spot monitoring, it gets the surround radar view and blind-spot cameras when you indicate.

The latest Model 3 has an additional centre airbag for a total of seven, as well as additional bolstering where the doors meet the body in response to requirements in its American home market.

It should be able to carry its maximum five-star ANCAP safety rating, which the original version achieved in 2019.

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.

Again, we've been asked to assume the Performance will come with Tesla's standard four-year/80,000km warranty and roadside assistance. And that the battery and drive unit will fall under an eight-year/192,000km warranty, whichever comes first.

Tesla says it monitors its cars to ascertain when they need servicing, and so it is based on a case-by-case situation. Every 12 months/20,000km is recommended for a general check-up, and includes tyre rotation.

Wiper blades, brake fluid and cabin air filters need replacement every two years while the air-con service is every six years.

Of course, there are no oil changes, filters or spark plugs to replace, and even brake pad wear is less than on an ICE vehicle because of the regenerative braking system. Although it will likely be higher in the Performance variant.
