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. 

Tesla has done enough with the introduction of this Premium Long Range RWD variant to keep the Model 3’s head well and truly above water in an increasingly competitive segment. After more than six years it still looks good, with a pleasant cabin environment, plenty of performance and leading energy efficiency. Safety is top-shelf and it stands up well in terms of practicality and driving dynamics. 

That said, the ownership proposition is average, the determination to make so many functions screen-based is frustrating and the optional Full Self-Driving system is unconvincing. With the Model S and Model Y now discontinued globally it will be interesting to see how the Model 3 continues to evolve.

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. 

After four years in market, a heavily upgraded version of the Model 3 arrived in Australia in 2023, the biggest visual changes being a reshaped bonnet, aero massaged overall profile and angular slimline headlights.

The boot lid now incorporates a lip spoiler and the tail-lights were remodelled to create a truncated, two-layer effect. And in true Tesla fashion, the standard 18-inch alloy rims are fitted with matt black-finish aero elements filling the gaps between the satin black wheel spokes. Two new body colours - ‘Stealth Grey’ and ‘Ultra Red’ - were recently added to the available palette. For reference, our test car's finish is 'Quicksilver'. 

It’s still clearly recognisable as a Model 3, but these relatively minor design changes have helped the mid-sizer keep up with the slew of sleek newcomers it now faces.

The interior was also given a substantial makeover, the expansive 15.4-inch central display screen backgrounded by an all-new wrap-around dash and revised console treatment, the former featuring a raised insert and the latter a two-device wireless charging station.

Introduction of this Premium Long Range RWD model also brought the small but significant addition of a physical indicator stalk on the left-hand side of the steering column, replacing buttons on the steering wheel. Big ergonomic tick for that.

Customisable ambient lighting lifts the tone, soft materials look and feel good and the doorcards, bins and armrests have been reprofiled into a more sophisticated arrangement.

Our test car’s dark grey and white synthetic leather trim combination lifts the mood as does light from the huge, two-panel glass roof. But beware, while white trim looks dazzling on the showroom floor it takes some extra work to maintain its schmick appearance in the day-to-day grind.

After seven years in market the Model 3 has aged well and still looks sleek and contemporary.

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. 

At just over 4.7m long, more than 1.8m wide and a bit over 1.4m tall (with a 2875mm wheelbase) the Tesla Model 3 is a low-slung medium-size sedan. 

There’s plenty of space up front, a feeling enhanced by the standard panoramic glass roof and our test car’s white trim brightening up the cabin.

There are long, wide bins on the front doors with enough room for large bottles, a slim glove box (which opens only via an on-screen button, which is annoying) and a generous lidded storage box between the seats that doubles as a centre armrest.

The console houses two cupholders with another storage cubby ahead of them (both with sliding covers over the top) and the dual device wireless charging bay on the lower part of the dash under the media screen.

Switching to the rear, at 183cm I have a surprising amount of foot, leg and headroom when sitting behind the driver’s seat set to my position. The rear door aperture is surprisingly large which helps entry and egress.

Technically able to accommodate three passengers, the back seat is best for two full-size adults on anything other than a mid-length journey, although the flat rear floor helps ease pressure on the centre occupant.

There's a well-hidden fold-down centre armrest with cupholders, there are useful bins in the doors and hard shell map pockets on the front seatbacks.

The crisp 8.0-inch rear screen is a welcome entertainment option for back-seaters and there are adjustable air vents underneath it.

For power and connectivity there are two USB-C ports and a 12-volt socket in the front compartment, a USB-A in the glove box (mainly for dash cam and ‘Sentry Mode’ data storage) and two USB-C ports in the rear under the vents.

Boot space is a ample at 682 litres (the bootlid is adjustable for opening height) with an 88L ‘frunk’ in the nose. And if you need to tow a relatively light load like a box trailer or Jet Ski (or two) you can hook up a 1.0-tonne braked trailer (750kg unbraked).

While we understand it helps maximise battery space and reduce weight, we’re not on board with Tesla’s policy of providing a repair/inflator kit rather than a physical spare tyre. Even though this is likely to be a primarily urban cruiser, it’s not good enough. 

Then, there’s the Tesla app, an electronic Swiss Army Knife that facilitates everything from remote vehicle access and cabin ‘preconditioning’ to planning your route (complete with charging stops) and monitoring Sentry Mode (checking the vehicle’s surroundings and receiving alerts of potential threats).

The list of functions goes on and on, but suffice it to say the app is hugely handy. For example, ‘Dog Mode’ keeps the air con on with the car locked for the benefit of your four-legged friend and lets passers by know the doggo is safe via a bold message on the central screen. An internal camera, accessible via the app, lets you check-in remotely, too. Nice. 

Given its overall size and despite its conventional sedan configuration, the Tesla Model 3 offers efficient packaging and a heap of thoughtful features to enhance everyday practicality.

At $61,900, before on-road costs in NSW ($67,329, drive-away), the Tesla Model 3 Premium Long Range RWD sits in the same price ballpark as other pure-electric mid-size sedans like the BYD Seal Premium RWD ($58,798, BOC), Hyundai Ioniq 6 2WD ($67,300, BOC), MG IM5 Platinum RWD ($69,990, drive-away) and Polestar 2 Standard range Single motor ($62,400, BOC).

Broaden the consideration set to include medium EV SUVs and a dozen other options including the BYD Sealion 7, Kia EV5, Skoda Enyaq and Zeekr 7X enter the picture, many with a price-tag around $10K lower than the Model 3’s.

But price is one thing, value is another. Aside from the performance and safety tech we’ll get to shortly, let’s look at the Model 3 Premium Long Range RWD’s included features.

Standard spec highlights include LED exterior lighting, new design 18-inch alloy wheels, a 15.4-inch central display screen, synthetic leather seat trim, power-adjustable ventilated and heated front seats, tri-zone climate control, adaptive cruise control and nine-speaker audio.

There’s also ambient interior lighting, navigation (with real-time traffic updates), an 8.0-inch rear touchscreen for back seat climate and entertainment, a power boot lid, dual wireless phone chargers, surround parking sensors, keyless entry and start (plus a lot more through the Tesla app, which we’ll cover in the Practicality section) and 360-degree acoustic glass (including the standard glass roof). Still no Android Auto or Apple CarPlay, though.

Add in less obvious improvements like the extension of soft-touch materials throughout the cabin and this Model 3 stacks up well in terms of value relative to its cost-of-entry and direct competitors.

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 Tesla Model 3 Premium Long Range RWD is powered by a single permanent magnet synchronous electric motor producing a handy 235kW and in excess of 400Nm.

It sends drive to the rear wheels only via a single-speed, direct-drive automatic transmission. 

Kerb weight is 1747kg and Tesla claims 0-100km/h acceleration in a rapid 5.2 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.

Tesla claims a WLTP range of up to 750km for the Model 3 Premium Long Range RWD, the official EV term for which is… a lot. 

As mentioned earlier, at the time of the car’s local launch in October last year Tesla claimed it as the longest-range EV in Australia and at the time of writing nothing had arrived to change that.

Unlike the standard Model 3, which is powered by a CATL-sourced LFP battery, the Long Range RWD is fitted with a lighter, more energy dense NMC pack from LG with a total capacity of 82kWh (78kWh usable).

In terms of energy consumption, Tesla claims 12.5kWh/100km on the combined (urban/extra-urban) cycle and on test we experimented with liberal use of the accelerator pedal, higher than average freeway running and keeping the car constantly chilled during extremely hot weather, which resulted in an average of 15.7kWh/100km. 

Aside from that, more typical stop-start urban driving with occasional use of the ‘Chill’ (eco-focused) mode brings the number down to 13.1kWh/100km.

That’s an impressive performance, with even the upper test figure more than acceptable for a 1.75-tonne electric sedan.

Capable of accepting a 250kW fast charge, Tesla says the Model 3 Long Range RWD can take on 311km of range in 15 minutes, at that speed.

On a 150kW pylon we saw capacity go from 15-85 per cent (theoretically, 600km of range) in roughly 50min, although the charger fluctuated below peak output throughout.

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.

So, surprise, surprise, the Tesla Model 3 Premium Long Range RWD is quiet. But it’s quiet, even in the context of other EVs in this part of the market.

That’s thanks in part to acoustic glass in the front, rear and side windows as well as the dual-pane glass roof and the Bridgestone Turanza T005 EV tyres (235/45x18) featuring ‘B-Silent’ technology. Corny, but it works.

A kerb weight under 1.8 tonnes is relatively lightweight for an EV of this size and the Model 3 RWD is quick with 0-100km/h acceleration in a fraction over five seconds. There’s always plenty of pulling power under your right foot. 

Suspension is double wishbone front, multi-link rear and ride comfort is respectable rather than exceptional. Smaller bumps and irregularities find their way into the cabin but never to an alarming degree.

Steering sits in the middle-of-the-road between tactile and wooden, which is par for the EV course, although it's accurate and pleasingly progressive. Body roll, even in enthusiastic cornering, is modest. 

The physical brakes are ventilated discs front and rear although they don’t come into play all that often because the Model 3’s regenerative braking system is so good. Single-pedal operation soon becomes the norm. 

Our test car’s optional ‘Full Self-Driving (Supervised)’ will set you back $10,100 as a one-off payment, or $149 per month and Tesla says when using it, “Under your supervision, your car will be able to drive itself almost anywhere with minimal driver intervention”.

We engaged it for a 30km trip through suburbia, across the Sydney Harbour Bridge and into the city’s inner south. 

A rainbow-coloured magic carpet in front of the car graphic on the nav map tells you the system is engaged and although things went smoothly at first we soon sliced a bit off the inner oncoming lane as we turned right at a T-intersection, which was alarming. 

The system also has a consistent tendency to stick to the far right-hand side of the lane, stay five to 10km/h under the signposted speed limit and it continued to operate without my hands on the wheel, although I kept them there for 99.9 per cent of the drive (which is tiring when you’re not doing the steering).

Having been squeezed to the point where we couldn’t merge safely into a particular arterial road the nav took us on what’s known in the trade as a wild goose chase that had to be nipped in the bud. If I hadn’t known my way around it could have been a huge waste of time and (vehicle) energy. As much a nav issue as an FSD one, but overall, let’s just say, I’m not convinced.

Under the heading of miscellaneous observations, I’m not a fan of the on-screen gear position slider in place of a physical control. It’s needlessly fussy, although its ability to automatically switch between D to R (and back) during slow-speed manoeuvres is helpful. 

The software behind the car’s multitude of functions is exceptionally good, as is the ability to swipe in the vicinity of the temp and audio volume screen sliders, rather than having to hit them bang on and the blind-spot camera view which pops up on the screen when indicating on either side is handy.

The Model 3 has a maximum five-star ANCAP rating from assessment in 2025, with outstanding scores across the independent body’s four key pillars: Adult Occupant Protection - 90 per cent, Child Occupant Protection - 95 per cent, Vulnerable Road User Protection - 89 per cent and Safety Assist - 88 per cent. Wow.

Active (crash avoidance) safety ticks a heap of boxes including AEB (operational from one to 150km/h with forward collision warning covering cars, cyclists, pedestrians and motorcycles) as well as rear AEB, lane keeping assist (car-to-car and car-to-motorcycle), lane departure warning, blind-spot monitoring, a 360-degree camera view, driver fatigue detection and more. None of them are overly intrusive in operation.

The airbag count runs to seven - front head and front side as well as full-length curtains, and a front centre bag to minimise head clash injuries between driver and co-pilot in a side collision. There’s also multi-collision brake (to reduce the chances of subsequent impacts after an initial crash).

For baby capsules or child seats there are three top-tether points across the second row with ISOFIX anchors on the two outer positions.

A super-impressive safety package that matches or betters anything in the category.

Worth noting our test car features Tesla’s ‘Full Self-Driving (Supervised)’ functionality which we’re positioning as a convenience feature rather than an outright safety factor. So, its performance is covered in the Driving section.

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)

From January 1, 2026 all new Teslas sold in Australia have been covered by a five-year, unlimited kilometre warranty (including roadside assistance for the duration), up from four years/80,000km, previously.

A big step forward, no doubt, but that just gets Tesla to a base, mainstream market level with a dozen brands now at seven years, several at eight and three at 10 years (conditional).

The drive battery is covered for eight years/192,000km, which is in line with the category norm. And a Body Rust Limited Warranty covers rust perforation for 12 years, unlimited kilometres, which is reassuring.

Tesla servicing is condition-based, so there’s no fixed schedule, with a summary on the car’s touchscreen providing a record of when vehicle maintenance was last carried out and prompts for when they should be performed next.

In the absence of a combustion powertrain the emphasis is on things like wheel rotation, balancing and alignment, brake fluid testing, air-con servicing, camera precision, radiator cleaning and high-voltage battery maintenance.

Theoretically, if a workshop visit is flagged in the car’s system, it could include actions like a ‘Vehicle Health Check’ ($270), ‘General Diagnosis’ (270 per hour), brake fluid flush ($240.80) and replacement of both cabin air filters ($106.60).

Things like air-con desiccant bag replacement ($89.18), tyre rotation ($81.00), a wheels check - if tyre wear is abnormal ($81) and a wheel alignment ($225) are also set inspection and service items. All prices exclusive of GST.

In the States, the brand provides a range of estimated annual service pricing of between US$257 - US$499 ($367-$712), based on data collected by car buying specialist CarEdge. The suggested service range is around 20,000km and the first five annual estimates are at US$300 ($430) or less.

Tesla has 25 stores in Australia, not surprisingly covering mainly urban and larger regional centres, including four each in Melbourne and Sydney, three in Canberra, two each in Adelaide, Brisbane and Perth as well as one in Hobart.
