BMW I3 vs Tesla Model 3

What's the difference?

Yes, it’s pricey for a small hatch, but this little BMW is a city car like no other. The i3s is tailor made for the urban environment, and six years on retains the quirkiness and charisma that stood it apart at launch, and it can still hold its head high among the current EV crop. 

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:

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

Built around a carbon-fibre reinforced plastic (CFRP) tub, the i3s is ultra-light (for a battery-electric vehicle), super strong, and unlike anything else on the road.

At just over 4.0m long, close to 1.8m wide, and a fraction under 1.6m tall, the i3s is compact, upright, and boxy. A classically polarising design, with some crossing the street to avoid it, and others (like me) loving its unique proportions and stand-out styling.

The nose is tall, short and upright, with the distance from the base of the front windscreen to the front axle (car designers call it the ‘dash-to-axle ratio’) unusually short.

That’s because the electric motor sits in the back of the car driving the rear wheels, with only a small front boot compartment required to house charging cables and other bits and pieces.

Despite the lack of anything of substance behind it, BMW’s signature ‘kidney grille’ is present and accounted for, with swoopy LED headlights (and DRLs) either side. Our test car’s ‘Fluid Black’ finish with ‘i Blue’ highlights dialed up the little car’s charismatic personality.  

One of the i3’s most impressive party tricks is its counter-opening ‘clamshell’ doors, and the engineering trickery used to create a B-pillar free side opening (including the strength of the carbon body structure) means the high window line follows a jagged path from front to back, the rearmost hatch windows shrinking the rear glass area appreciably.

The i3s’s standard 20-inch (dual) five-spoke alloy rims, although slightly wider in this performance model, are alarmingly skinny. But taking the car’s relatively light weight (1245kg) and urban-centric purpose into consideration, the narrow, low-rolling resistance rubber makes sense.

With the roofline and sides of the car tapering distinctly towards the back, the rear view is suitably idiosyncratic, highlighted by flush-fit, vaguely U-shaped LED tail-lights. 

The hatch window is small, and the bumper sits high to marry with the load space floor sitting on top of the motor and transmission.

And when it comes to moving inside, BMW offers a choice of three ‘interior worlds - ‘Loft’, ‘Lodge’, and ‘Suite’ - featuring renewable natural fibres, recycled plastics, naturally tanned leather, and open-pore wood (sourced from 100 per cent Forest Stewardship Council-certified forestry).

But irrespective of where everything comes from, the end result is inviting, comfortable and sub-zero cool. Our car’s ‘Suite’ interior was combined with ‘Oak dark matt’ wood, and ‘Vernasca’ brown leather to stunning effect.

A tunnel-free floor, gently curved dash and digital screens for instruments and media let you know you’re in something different and special. It might be six years old, but the i3 still feels contemporary and distinctive. 

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.

Wide-opening clamshell doors make getting in and out of the i3s a breeze. But bear in mind you have to open the front door to get to the latch for the back one, which can be a pain.

The driver and front passenger enjoy heaps of room, in an open environment, but there’s only a single cupholder in the centre console, so let the coffee cup wars begin.

Aside from that there are seriously big bins in the front doors, a modest glove box, and a handy elasticised pocket near the floor at the base of the bulkhead.  

Outlets for 12-volt and USB are provided, and there’s a small oddments tray at the rear of the centre console.

Slip around to the rear and you’re in anything but limousine territory. Sitting behind the driver’s seat set for my 183cm height, head and legroom are modest but do-able. And remember it’s two seats only back there.

In terms of storage, there are two cupholders between the seats but no storage pockets or bottle holders in the doors. You won’t find adjustable ventilation outlets either, but that’s not a huge factor in car of this stature.

The boot’s volume is quoted at 260 litres with the 50/50 split-fold rear seatback upright, which is enough to easily swallow the largest 124-litre suitcase in the CarsGuide three-piece set. The smaller 95- and 36-litre cases will sit side-by-side without a problem.

Fold the rear seat down and you have 1100 litres of space at your disposal, with tie-down anchors, an elasticised pocket and 12-volt power provided.

Don’t bother looking for a spare of any description, a repair/inflator kit is your only option. And not surprisingly, the i3 is a no-tow zone. 

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.

The i3s is powered by BMW’s ‘eDrive’ hybrid synchronous electric motor, producing 135kW at 7000rpm, and 270Nm from 0-4500rpm. Yep, that’s right, maximum torque is delivered the instant you depress the right-hand pedal, and we’ll get to what that brings to the driving experience a little later.

The unit incorporates a charging and generator function for braking energy recuperation, the latter delivering up to 50kW.

Drive goes to the rear wheels via a single-speed (fixed-ratio) automatic transmission.

The battery powering the whole show is a 352-volt/120 amp-hour (Ah) Lithium-ion unit with a (gross) energy rating of 42.2kWh.

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.

When it comes to an electric car’s energy use and projected range, there are two main things to consider - the motor’s power consumption and the battery’s capacity.

And according to BMW, the i3s’s power consumption for the combined (urban/extra-urban) cycle is 14.6–14.0kWh/100km.

Over a week, and roughly 250km of urban driving (with some brief freeway runs thrown in) we saw 19.3kWh/100km staring back at us from the on-board computer.

When BMW launched the i3 in Australia in 2014, the pure EV version came with a 60Ah battery pack delivering a claimed 130 kilometre range (a range extender model featuring the addition of a two-cylinder petrol motorcycle engine was also offered). 

In 2016 a 94Ah version arrived to boost range up to 183km, and the i3s launched in 2018, with its 120Ah battery pushing range out to BMW’s current, real-world estimate of 260km.

Then, there’s charging time, which is like asking how long is an electric piece of string.

According to BMW, for a 0–80 per cent charge from a (50 kW DC) fast-charging station, you’re looking at 45min.

From a (11kW/16A/380V) high-output home/office wall unit, that pushes out to 3.10h, and using a (3.7kW/16A/240V) low-output home/office unit stretches the wait time to 9.40h.

BMW offers the ‘WallBox plus’ charging suite as a dealer accessory priced from $1990 (not including GST or install costs).

Plug into a domestic (2.4kW/10A/240V) socket, and you’re staring down the barrel of 15.00h. But at least you can use low-cost, off-peak energy overnight, right? Nah, I don’t buy that line either.

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.

It might not look like a conventional sports car, but the BMW i3s certainly accelerates like one, with a claimed 0-100km/h time of 6.9sec. The i3s is a smile-inducing hoot to drive.

Every one of this little hatch’s 270 newton metres of torque is available from the minute you hit the accelerator pedal, and remain in service until 4500rpm, at which point torque delivery drops off a cliff.

But peak power steps in at exactly 7000rpm, so if you’re determined to make that overtaking move you won’t be left in the lurch. In fact, BMW says it only takes the i3s 4.3 seconds to surge from 80km/h to 120km/h.

However, the i3’s forte is 100 per cent the city, rather than the open road. Its ‘point and squirt’ ability making it the perfect partner for the cut and thrust of the urban jungle.

The i3s features an upgraded ‘Sports Suspension’ incorporating firmer dampers, re-tuned springs and revised anti-roll bars. It’s also lowered 10mm, the track is widened (+21mm front / +2.0mm rear) and the wheels go plus one inch to 20-inch alloys.

The standard i3 (no longer offered in Australia) rolls on 19-inch rims shod with 155/70 rubber all around. And while the i3s’s 175/55 front and 190/50 rear tyres are still exceptionally narrow, from the side the low-profile Bridgestone Ecopias look like fan belts wrapped around pulleys rather than tyres around wheels..

No surprise then that ride comfort isn’t exactly cushy, and in signing on for the i3s experience you’ll need to be ready for more than occasional bumps and thumps.

But the pay-off is super-sharp dynamics, Suspension is by alloy struts at the front, and a five-link alloy set-up at the rear..The steering responds to inputs quickly yet smoothly, and with 48/52 front to rear weight distribution, the car always feels balanced, eager, and taut.

And if you really want to dial things up the ‘driving experience control’ allows a switch to Sport mode for a further tweak of the suspension, steering, and traction control set-ups.

A tight 10.3m turning circle makes for easy parking and stress-free U-turns. But if things get too tight, rapid three-point turns are assisted by the gear shift controller bring mounted on a chunky stalk on the right-hand side of the steering column. Too easy.   

Braking is by vented discs front and rear, but they’re tiny. That’s because the ‘Brake Energy Regeneration’ system does most of the work. 

Effectively turning the motor into a generator, the system not only slows the car dramatically but feeds energy to the battery in the process. It takes a while to get used to the sensation, but soon becomes a fun, and surprisingly easy game to use the brake pedal as little as possible… often not at all, for long periods.

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.

BMW offers a three year/unlimited km warranty, which is off the pace given the majority of mainstream brands have stepped up to five-year cover, with some at seven. And the pressure is on with Mercedes-Benz recently announcing its shift to five years/unlimited km.

That said, the BMW's body is warranted against rust (perforation) for 12 years/unlimited km, and roadside assistance is provided free-of-charge for three years/unlimited km.

Maintenance is 'condition based' with sensors and on-board algorithms (mileage, time since last service, driving style) determining whether an annual vehicle inspection is required.

The 'BMW Service Inclusive' package, offering a single, one-off advance payment to cover selected service and maintenance costs, is available in two levels - 'Basic' ($850) or 'Plus' (dealer quote)

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.
