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. 

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.

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. 

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.

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. 

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. 

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.

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.  

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.

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.

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.

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.

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)

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.
