BMW I3 vs Hyundai Inster

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 target market for the Inster isn't huge, and Hyundai knows it won't be a runaway best-seller for the brand. But those in the market for a bite-sized EV will find the Inster feels bigger, and drives better, than they might expect.

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 words small but perfectly formed appear here, with Hyundai’s insistence on not having a traditional range-wide design identity allowing them the freedom to create something unique and pretty funky here — though I do see some shades of Suzuki Ignis in the side profile.

It does look fun though, right? With the selfie ring-light-style headlights, Tetris-style rear lights, those swollen guards and the funky alloys.

And you can dial up further with the Cross variant, which gets a tougher, more squared-off look front and back - even if you’re more chance of meeting a bunyip than an Inster on your favourite off-road track.

Inside, the cuteness continues, though some of the scratchy cabin materials definitely point to the entry-level nature of the Inster.

Still, the seat materials, both the cloth and the leather, are lovely and thoughtfully coloured, and the twin screen setup is nice, too. I love the inclusion of a host of physical buttons that control the climate, stereo and the nav.

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 Inster stretches 3825mm long, 1610mm wide and 1575mm tall, but it rides on a 2580mm wheelbase – the later being bigger than the Hyundai Venue, and almost as big as the Kona.

It has allowed Hyundai to stretch the legroom options in the backseat, which actually gives you more space than the two bigger SUVs mentioned above, helped massively by the fact the Inster's rear pew is on rails, allowing you to slide it right back, and that it reclines a fair way, too.

I'm 175cm and I found I had more than enough leg and headroom, and with the backseat in full La-Z-Boy mode, I could sit back and relax, even on a longer journey.

It's a good thing it's four seats only, though. While the Inster feels longer than it is, it doesn't feel any wider, and even in the front seat you can feel like you're in economy class when you have a passenger on board, with both of you rubbing elbows on the central armrest.

Clever storage abounds though, with hidey-holes, handbag hooks and more dotted throughout the cabin. Opt for the roof box – and wear the efficiency penalty – and you can pop another 75kg worth of gear on the roof.

Also cool is the fact the backseats fold completely flat in the entry-level Inster, upping the storage possibilities. And in the top-spec Cross, the front seats fold down, too, allowing for fairly long items to be stowed. Though why you would need the driver's seat to fold flat is a bit of a mystery, unless you're looking to turn your Inster into an immovable storage container.

Apparently in Korea you can option a mattress that slides over all four seats, but I can't see that taking off here.

The official storage numbers are 280L and 1059L, and the small boot is helped along a little by underfloor storage where you can pop your charging stuff.

The Inster is available as an entry-level model, which comes as a Standard Range for $39,000 before on-road costs, or an Extended Range for $42,500. It then steps up to the Inster Cross, which is $45,000.

For perspective, the Geely EX5 is considerably bigger, and will travel further on a charge, for $40,990 before on-road costs. Then there's the Chery E5, which is now  $39,990 plus on-road costs.

Anyway, the Inster nabs 15-inch wheels, dual 10.25-inch screens (one for the multimedia, another for driving info), a six-speaker stereo, Apple CarPlay and Android Auto, cloth seats, two V2L connectors, a wireless charging pad and rain-sensing wipers. The equipment list for the Extended Range is the same, but it rides on 17-inch alloys.

Stepping up to the Inster Cross scores you a unique and off-road-inspired look, but also leather trim inside, a unique design for its 17-inch alloys, heating and ventilation for the front seats and heating for the steering wheel, some extra safety kit and practicality perks, and the option of a sunroof or an exterior roof storage box, the latter of which seriously eats into the driving range.

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 Hyundai Inster Standard Range kicks off power proceedings, with a single front-mounted electric motor producing 71kW and 147Nm.

Next is the Extended Range, which shares its outputs with the Inster Cross. Here, the front-mounted motor’s outputs have been ticked up slightly, now producing 84kW and 147Nm.

Those aren’t big numbers, but then neither does either Inster feel particularly slow or underpowered. 

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.

Standard Range cars get a 42kWh lithium-ion battery, producing a driving range of 327km. The Extended Range and the Cross get a bigger 49kWh battery, increasing the range to 360kms. Now, that roof box. It does look cool, but you’re going to really need to carry stuff to choose that option, given it increases energy consumption by 25 per cent, reducing the Cross’s range to just 293km.

When it comes to charging, the Inster is set up for 120kW DC fast charging, or 10.5kW AC charging - provided you have that much power available at home, as most wall boxes are more like 7.1kW.

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.

Honestly, the impact electrification has had on vehicles in this class is staggering.

It wasn't so long ago that these micro cars were fitted with underwhelming petrol engines, four- or five-speed gearboxes and all the noise-deadening technology of a tin of beans.

As a result, they were cute, but painful. It always felt like you had to wring their neck to get the most out of them, and when you did, they were loud, buzzy and annoying.

But the Inster is none of those things. While not ludicrously powerful, the electric propulsion offered, and the nature of the way it's produced, feels ample in the little Hyundai, with the acceleration smooth, silent and easy,

It's also just generally quiet. Hyundai says it has double-sealed the doors, used thicker glass and fitted full underbody coverings to reduce the NVH - or noise, vibration, harshness - levels, and all of that, combined with the peace and quiet of an electric motor, have created a mostly blissful cabin experience.

The ride and handling hasn't been through the full Hyundai Australia ride and handling calibration of old. Instead, it's undergone the brand's more modern approach, which is to take the best componentry from what's available overseas and then build the Aussie-spec cars from there.

Either way, it all works pretty well here. Only really big bumps clang into the cabin, with the Inster otherwise riding well over all of the road surfaces we encountered.

The point, I guess, is that it's a drive experience stuffed full of happy surprises. The ride, the acceleration and the refinement are all well up on what you might expect from a city car.

The Hyundai Inster is yet to be crash tested, but does arrive with a solid safety offering including seven airbags, as well as active equipment like a auto emergency braking (AEB), rear cross-traffic avoidance, lane keep assist, and active cruise control.

The Cross ups the equipment a little more, including a surround-view monitor, blind-spot monitoring and front parking sensors.

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)

The Inster delivers super long service intervals, requiring a trip to the service centre every two years or 30,000kms, but each service is priced at $655. A Toyota Yaris Cross, for perspective, will see you visit the service centre twice as often, but each visit will only cost you $255, or $510 every two years.

The Hyundai warranty is five years/unlimited kilometres, while the high-voltage battery is covered for eight years.
