BMW I3 vs Kia EV6

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 Kia EV6 Air offers comfort, a good range of features and beautiful handling for a ‘base model’, but it is a little pricey considering its competition.

Having said that, if you’re looking for an EV that will fit the family and has a stellar safety list – this is one to consider.

My son reckons the EV6 looks 'really cool' and he loves the space in the back seat.

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 EV6 is cool and fun-looking, but being the base-model does mean you get plastic rather than body-coloured mouldings around the base of the car, which highlights its grade level.

The exterior hosts 19-inch alloy wheels and a full suite of LED lights but misses out on the upgraded Matrix headlights that the higher grades get.

The exterior's swoopy curves look aerodynamic and the chunkier rear balances out the sharper nose.

The interior looks well-made, and the mix of high-end cloth and synthetic-leather materials complement the futuristic exterior aesthetic.

The dashboard is headlined by a curved panel that houses the dual 12.3-inch tech screens and the floating centre console leans into that future vibe again.

There's a nice mix of touchscreen and physical buttons to satisfy a wide audience. Overall, while it’s not as flashy as its siblings, the cabin of the Air is very pleasant to look at.

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 space in the EV6 rivals much larger SUVs and tall families will rejoice with how much leg- and headroom you get in both rows.

The comfort for passengers is pretty good, with comfortable seats in both rows that feel well-cushioned. The floor in the rear is flat, which accommodates any middle-seaters.

Being the base grade, you don’t get electric front seats, which is a bit rough for its price point but the driver’s side does get powered lumbar support, which I appreciate on longer journeys.

Individual storage is fantastic for the class and the front gets two cupholders, a drink bottle holder in each door and glovebox and middle console. There are multiple storage nooks and a utility tray on the topside of the floating centre console (sized for items like keys, wallet, phone etc).

The large shelf underneath the centre console easily accommodates a handbag and snacks for any kids in the back (or adults, no judgement).

Individual storage in the back is as good as the front, with plenty of spots to tuck away all of the paraphernalia that kids seem to attract. There are also two cupholders in a fold-down armrest, a drink bottle holder in each door and map pockets.

On the whole, my seven-year-old really enjoys being in the back seat because of the amenities and space he has. He finds the EV6 to be an easy car to get out of but we all struggle with the flush door handles! They can be terribly annoying to use as they don’t pop out on approach or when you unlock the doors. If you have your hands full and have little T-Rex hands like me, it can be awkward to open.

What isn't awkward to use is the technology! The 12.3-inch touchscreen multimedia system is quick to respond and the system itself is easy to navigate once you spend some time with it.

The 12.3-inch digital instrument cluster is semi-customisable but not as pretty in its graphics as it could be. It has two styles to choose from - white or black, and the white is a little too sterile for my liking.

The multimedia system features wired Apple CarPlay, Android Auto and built-in satellite navigation with map updates for 10 years.

Charging options are solid with a single USB-A and and two USB-C ports up front, a wireless charging pad and a two 12-volt ports to choose from. The rear enjoy a three-pin standard house port and two USB-C ports as well.

The back seat has a 60/40 split and it's handy that you can lower them from the boot with manual levers. The boot itself is a good size with 490L when all seats are in use but you miss out on a powered tailgate in this model.

The frunk storage also offers an additional 52L, which is perfect to keep any charging cables or the tyre mobility kit stored away.

The Kia EV6 Air is the base-model in a four-variant line-up but is still priced at $72,590 before on road costs.

That positions it as the most expensive option compared to its nearest rivals. The Hyundai Ioniq 5 2WD is the closest at $71,000 but the Tesla Model Y RWD base model is $7190 more affordable.

Compared to it's siblings, the Air isn’t as well-equipped with the luxury features, but it doesn’t feel basic either because the technology is top-notch.

There is a 12.3-inch touchscreen multimedia screen and a 12.3-inch digital instrument cluster, plus built-in satellite navigation, as well as wired Apple CarPlay and Android Auto. Other tech features include dual-zone air-conditioning, single USB-A port, four USB-C ports, a wireless charging pad and a full suite of LED lights.

A mixture of premium cloth trims and synthetic-leather upholstery gives the cabin a premium feel, but being the base model does mean you miss out on the upgraded sound system. The base sound system with its six speakers is sufficient for every day use.

The seating features manual adjustments, but the driver's side does enjoy powered two-way lumbar support, which I appreciate on a long journey.

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 EV6 Air is a single-motor rear-wheel-drive that produces a maximum power output of 168kW and 350Nm of torque.

The Air has the slowest 0-100km/h sprint time in the EV6 range at 7.3 seconds, but that’s honestly enough for my little family. It still feels pretty damn zippy when you put your foot down.

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.

Officially, you get a driving range of up to 528km (WLTP) from the 77.4kWh lithium-ion battery. However, the longest range I ever saw was 480km, which admittedly is still very good.

The EV6 Air has a Type 2 CCS port, which means you can benefit from plugging into a fast charger and the accepted voltage is a whopping 800v.

On a 50kW system, you’ll get from 10-80 per cent charge in 73 minutes and on a 350kW system, which charge time drops to just 18 minutes.

Expect it to take longer on AC charging, though. To get from 10-100 per cent on an 11kW system, it will take approximately seven hours and 20 minutes. On a standard house plug ... expect it to be on charge for around 30 hours.

The Air also has a vehicle to load (V2L) capability – meaning, it has a standard house three-pin plug port available to charge larger appliances while on the go. 

The official combined energy consumption is 16.5kW/100km (WLTP), and my usage came out at 16.02kW after a mix of open-road and urban driving this week.

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.

The EV6 Air handles itself really well, it's been hit by torrential rain and didn’t skip a beat.

The Air really grips the road and distributes the power through the rear wheels evenly. Even at higher speeds, there’s no wobble and it feels stable when you accelerate. 

Steering is on the right side of firm and makes the Air feel very zippy when navigating tight city streets.

There are three levels of regenerative braking available, as well as a one-pedal function called iPedal, which is probably the best I’ve sampled and I like how responsive it is in stop-start traffic. However, when using this function on hills, I still hover over the brakes as it can still roll forward a bit. 

The cabin can get really loud from road noise at higher speeds, but it seems to come from underneath the carriage, rather than through the windows. The suspension is well-cushioned but not spongy.

Parking the EV6 isn’t an issue once you get used to the rotary gear selector and the reversing camera is super clear. You get a 360-degree system on higher grades but the Air does come with front and rear parking sensors.

The Kia EV6 Air is well equipped with safety features and it's here that you don't feel like you're in the 'base model'.

Standard features include the biggies like forward collision warning, blind-spot monitoring, rear cross-traffic alert, lane-keeping aids, lane departure alert, driver attention alert, reversing camera and front and rear parking sensors.

Considering the Air is a base model, it's also great to see items like blind-spot collision avoidance, safe exit warning, rear occupant alert and haptic-feedback on the steering wheel (as an additional 'sense' warning).

I rejoiced when I discovered that the Traffic Sign Recognition technology has been tweaked to not sound or alert on every traffic sign or speed change. It still chimes in school zones, but you no longer have to go into the menu to downgrade the sensitivity! Hurrah!

The Air has AEB with car, pedestrian, cyclist and junction turning assist, which is operational from 5.0 - 85km/h but it is usual to see that top figure be well above 100km/h, so this is surprising.

The EV6 achieved a maximum five-star ANCAP safety rating from testing done in 2022 and features seven airbags, including the newer front centre airbag.

There are ISOFIX child seat mounts on the rear outboard seats plus three top-tethers. You might get lucky in fitting three skinny child seats but two fit the best and there’s plenty of space for front passengers when a 0-4 rearward facing child seat is installed too.

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 EV6 comes with a leading seven-year/unlimited-km warranty. The battery covered by a separate seven-year/150,000km term, but this is a smidge shorter than some of its rivals.

You can pre-purchase either a three-, five-, or seven-year servicing program, priced at $721, $1382 and $2045, respectively. All of which are reasonable for the class.

The seven-year program runs up to a max 105,000km.

Servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.
