BMW I3 vs Tesla Model Y

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. 

Tesla promised wholesale improvements to the Model Y, and this Juniper update delivers where it counts. But with increased, and sometimes cheaper, competition arriving every day, the pressure remains on Tesla to keep the Model Y ahead of the pack.

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. 

We’re not talking massive changes here – more a modernising of the Model Y offering that doesn’t really change the shape or dimensions. 

The most noticeable changes outside are the front and rear light bars, spanning the width of both the bonnet and the boot. They’re a nice touch, and seriously soften what many (including me) consider the worst angles of the Model Y. There are also new headlights, a refreshed front bumper and a new look for the alloy wheels.

Inside, it is the absolute definition of pared-back minimalism. In fact, some could argue it’s gone a little bit too far.

There are no physical buttons anywhere but on the steering wheel, and there's just the one stalk, which has the sole function of operating the indicators. Everything else - mirrors, windscreen wipers, headlights etc - are accessed either through the steering wheel, or through the central screen.

And that includes the gear selector, which is now a swipe-down-for-reverse, swipe-up-for-drive function on the central screen. You might love that, but I don't. I'm sure I'd get more used to it, but initially it did nothing but slow down how quickly I could get the car moving.

Helpfully, the central screen is big and very easy use, and logging into Spotify and Apple CarPlay does largely negate the missing phone mirroring – though if the function exists, I couldn't get it to read my incoming texts to me.

Our test car's cabin was black but highlighted with quality-feeling fabric panels in the doors and on the dash, which are then framed by a metallic-feeling mesh, helping the Model Y's cabin feel definitely elevated from the vehicles that came before it.

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. 

The new Model Y stretches 4792mm long, 1982mm wide and 1624mm tall, and the practicality perks of the outgoing model still shine strongly in this new version.

Climb into the backseat and you’ll find a seriously spacious area, and one that feels even bigger and lighter thanks to the completely flat floor and the glass roof.

Even sitting behind my own 175cm driving position, there was ample knee and headroom, and the addition of the 8.0-inch rear screen, which supports two headphone connections, is a clever touch. Gone are the mind-numbing days of staring out the window on long family road trips. Now, kids get access to YouTube, Netflix and a heap of games.

There are also two USB charge points, and a pull-down divider that separates the comfortable rear seats. The door pockets front and rear are sizeable, and cabin storage abounds, including a hugely deep storage bin that separates the front seats.

Open the boot, and remove the shade, and you'll find another fairly massive storage area, including a deep hidden area under the boot floor. But you won't find a spare tyre – instead Tesla offers a 24-hour call-out service for the life of the warranty, where someone will come and repair or replace your tyre, should you have an issue.

Tesla isn't good at detailing specifics about its vehicles, but says you can expect a total 2138 litres of storage space in the Model Y, presumably with the rear seats folded flat and measured to the ceiling.

So yes, this Model Y RWD is the cheapest way into the Model Y family, listing at $58,900 before on-road costs – exactly $10k cheaper than the Long Range All-Wheel Drive.

That’s a little more than some of its core Chinese rivals, like the XPeng G6 which kicks off at $54,800, and a lot more than vehicles like the Leapmotor C10 and Geely EX5. But you could argue that Tesla has more brand standing than them in Australia, given it has been around for so much longer. 

Tesla has also jacked up the included features for this update, with heating and cooling for the front seats, new 19-inch alloy wheel designs, adaptive LED headlights, and a very cool 8.0-inch rear screen that gives backseat riders access to games, YouTube and Netflix.

Tech up front is handled by a 15.4-inch central screen on which you can connect your Spotify or Apple accounts, but there’s no Apple CarPlay and Android Auto. The system pairs with a nine-speaker stereo, and there’s still the best wireless charging pad in the business below the screen.

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.

Again, Tesla keeps its cards close to its chest on specific outputs, but data we've seen points to this Tesla's rear-mounted electric motor producing 255kW, a smallish increase from the 220kW of the outgoing model.

Tesla says that's enough to produce a sprint to 100km/h time of 5.9 seconds.

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.

Again, more cloak and dagger from Tesla here, but most reporting suggests a 75kWh battery is housed beneath the new Model Y.

We do know that our rear-drive Model Y will deliver a claimed 466km driving range on the WLTP cycle.

Charging is capped at a reported 220kW, with the brand suggesting 238km in driving range can be added in 15 minutes when using a 175kW Supercharger. Home AC charging is capped at 11kW.

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.

Reviewing a Tesla Model Y at the moment is no mean feat. The company's very public figurehead is fighting for a front-row grid position in the battle for world's most unlikeable human at the moment.

But anyway, journalist hat on, personal views aside, Tesla has done a good job with the new Model Y. I actually didn't much like the outgoing model – the ride was too harsh, the steering too darty and the cabin too austere – but Tesla has comprehensively overhauled each of those drawbacks to create a car that is genuinely much better than it has ever been before.

Let's start with the cabin. It's still austere, but the quality feels higher and more premium, and while I'll die on a hill of the screen-controlled drive selector being a bad idea, it is otherwise now a nice place to spend time. The screen and the software powering it largely replace the perks of Apple CarPlay, and the addition of the rear screen is a very good one, too.

But the biggest improvements are in the way the Model Y drives. It's far more compliant on Sydney roads, while the steering sensitivity has been dialled back so it doesn't feel as though you're constantly making corrections.

I also like the power delivery in the RWD. It's not lightning fast, but the grunt is constant and feels really instantaneous and usable.

It's no sports car, though. Our test car took in some of the windiest roads in greater Sydney and beyond, and while the body roll and composure feels on point, the Model Y does struggle with really sharp cornering. The aggressive traction control was a constant passenger on the really challenging stuff.

Overall, the improvements are good, and very noticeable.

This Tesla Model Y wears the same five-star ANCAP safety rating as its predecessor, awarded back in 2022.

Everything you expect is present and accounted for, including seven airbags, auto emergency braking (AEB), lane departure warning and assist (the latter being a little too panicky for my tastes) and cameras front and rear.

Special mention for the brand's semi-autonomous functionality, which – while not perfect – is among the best I've experienced. On the highway, it will stay in the centre of its lane, rather than the bumper-bowling-style swaying that some systems serve up, and change lanes for you when you indicate.

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)

Underwhelming, I'm afraid. A four-year/80,000km warranty might be the worst offered by any mainstream brand in the country. For the record, five-year/unlimited km is now the minimum standard, with many brands far exceeding that.

Servicing intervals are a bit scattered, with the brand instead listing when things need to be done, rather than a traditional schedule.
