Toyota Corolla vs BMW I3

What's the difference?

The final score for this review makes it look as though the Corolla is a middling effort. The scores for each individual section of the review are well considered and fair. The Corolla does lack the practicality of some of its rivals. A lack of an ANCAP rating isn’t great and the powertrain is just okay. But it remains one of the most fun-to-drive hatchbacks on the market today, even seven years into its life, and I would wholeheartedly recommend the Corolla to anyone looking for a small car. If you can forgive some of the quirks, it is a reliable, adorable, fun and efficient small car favourite. 

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. 

It’s been around for a good seven years, but the current-gen Corolla hatch is still a smart design. It has a squat stance and looks as though it has sporty intentions (it doesn’t), and the head and tail-light treatment doesn’t look like anything else in the segment.

The Corolla has adorable proportions and a pert little behind in a sea of increasingly boring small SUVs.

However, in SX trim and in the ‘Sunstone Orange’ body colour of my test car, the Corolla gives off rental car vibes. Which is hardly surprising given lower grade Corollas are a favourite of rental companies.

Inside that vibe continues. This is where the Corolla is really showing its age.

There are various shades of grey throughout the cabin, with a mix of hard and soft plastics. The cloth seat trim is drab, which is a shame because some other brands have managed to make cloth cool again. Not Toyota.

The touchscreen sticks up out the top of the dash like an old iPad and the dash design is old but functional. 

There is nothing inspiring about this interior design. In saying that, of those aforementioned rivals, only the Mazda3 and the new Kia K4 have modern cabins.

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 Corolla is a small car and that is evident inside. You might bump elbows with your front passenger, but I have no problem with the front leg or headroom.

Those cloth seats might be drab but boy they are comfy, and the fronts have loads of side bolstering. 

The steering wheel has typically clear controls and looks and feels nice. 

As a more, shall we say seasoned model in the segment, the Corolla still has buttons on the dash for things like air con, but not too many. That bulbous centre stack and the centre console, however, could be better designed for the space.

As it is, the wireless charging pad is hidden under it at the far end of the console. It’s a bit fiddly to get your phone in and out. This is also where one of the USB-C ports lives.

The other one is in the central storage bin which is quite small, but also houses a 12-volt outlet. There are no other places to store things because of the rounded shape of the console, which also features a couple of narrow cupholders.

OurCarsGuide bottle had to be squeezed into the door storage cavity - only narrow, short vessels will fit properly.

That 8.0-inch multimedia screen is very easy to navigate, with logical menus and icons. However, it’s almost too basic, which is not helped by the all-white background. It could be a more engaging set-up but it’s also very hard to fault the functionality. Our Apple CarPlay maintained its connection the whole time with the car, too.

Space is quite tight in the rear, although I have enough headroom for my 184cm frame. Legroom is just okay behind my driving position. There’s more space in the back of a Hyundai i30. It’s also dark because of smallish rear windows and thick C-pillars. 

The rear seat backrest is quite upright, but, like the front seats, well cushioned.

Amenities are just average back there - there’s a weird cupholder high on the door, only a passenger side map pocket, no rear air vents and no USB ports, although you could easily use the one housed in the front central bin. There’s a rear fold-down armrest with two cupholders.

The rear seats split and fold 60/40 and they fold flat making for a better loading space.

The good news is the SX (and the base Ascent Sport) come standard with a temporary spare wheel, which is great news for a hybrid model. The bad news is, that reduces boot space to a paltry 217 litres. 

That’s off the pace of all of its key hatchback rivals, including the Mazda3 which has its own cargo concerns at 295L, and the Hyundai i30 with 395L.

The Corolla ZR hatch has more space at 333L but you only get a tyre repair kit instead of a temporary spare. 

If you’re dead set on a Corolla but need more cargo space, consider the smart looking sedan that has 470 litres.

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. 

For a compact, four-seat hatch the BMW i3s is all the money at $70,900, before on-road costs. Close to $20K more than even the top-spec ‘Premium’ version of Hyundai’s Ioniq electric hatch ($52,490), and even further away from Renault’s cute little Zoe ($49,490).

But a carbon monocoque body and high-tech powertrain don’t come cheap, and that’s where BMW’s ‘i’ model program has seemingly run out of juice.

Getting into the EV market early, BMW took a punt on niche vehicles using exotic materials, appealing to a relatively small group of premium buyers. And in glorious hindsight, that path has proved something of a dead end.

But putting all that to one side, it’s fair to expect a generous standard equipment list in a $70K-plus BMW, and the i3s comes to the party with a solid, if not spectacular batch of features. 

Aside from the safety tech detailed later, Included is a 10.25-inch media touchscreen, managing audio, built-in nav (with real time traffic alerts), phone connectivity and more.

Other features include, wireless phone charging (for compatible devices), a rear-view camera, automated parking assist, active cruise control (with stop-go function), climate control air, driver’s digital display, ambient interior lighting, 20-inch alloy wheels, auto LED headlights, LED DRLs, indicators and tail-lights, keyless start, rain-sensing wipers, plus heated and folding power mirrors.

But there are a few surprises. It might be an electric car, but forget power adjustment of either front seat. And despite inclusion of Apple CarPlay (BMW says Android Auto will be available later in 2020) and digital radio, the audio system only has four speakers, all in the front doors (because of the clamshell arrangement detailed later). 

Our test car featured the ‘Suite’ interior package ($2308) which brings ‘Vernasca Dark Truffle’ leather on the seats, instrument panel, doors and side trim, as well as ‘Oak dark matt’ wood trim, the steering wheel in black with a ‘Satin Silver’ contrast ring, floor mats (and general interior fabrics) in ‘Anthracite’, the roofliner in ‘Carum Spice Grey’, plus orange/white LED lighting for the door pull handles and front map pocket. A dual porthole-style glass sunroof adds another $2246, for an as-tested price of $74,454.

Since Toyota dropped the petrol engine from the Corolla range, it’s a hybrid-only affair.

The powerplant is a 1.8-litre naturally aspirated petrol engine paired with Toyota’s fifth-generation hybrid system that incorporates a lithium-ion battery, which is lighter yet more powerful since the 2022 update.

The Corolla drives the front wheels exclusively via a continuously variable transmission (CVT).

It’s not the punchiest engine and could do with more poke, but Toyota does do hybrids well. 

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.

According to Toyota the official fuel-use figure for the Corolla hybrid hatch is 4.0-litres per 100 kilometres and CO2 emissions sit at 90g/km.

While the trip computer said 4.8L/100km at the end of our week, my own fuel consumption calculation came to 5.8L.

You will only need 91 RON 'standard' petrol to fill up the Corolla.

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.

Most generations of Corollas have been solid, dependable and occasionally, even fun to drive. 

My first car was a Holden Nova GS hatchback, which was a rebadged version of the seventh-generation Corolla. I loved that car. It was zippy, fun and super economical.

The same principles generally apply to the current-gen Corolla. Thankfully, Toyota’s former CEO, Akio Toyoda, insisted all models from the Camry to the Kluger needed to be injected with more fun. And he succeeded with the Corolla. So much so that they've spun off a wild GR performance hot hatch version.

The Corolla sits low to the ground and it just feels much more connected to the road than a small SUV can. Even in mid-range SX guise, the Corolla can hug a corner and there is ample grip to ensure a fun drive on your favourite winding road.

Sure, the hybrid powertrain might not set your heart racing, but it is quick enough from a standing start and it lacks the lag of some of its turbocharged contemporaries. There’s also plenty of poke on tap for a small car when overtaking.

Even though it has a sporting edge to how it handles, the Corolla SX has been tuned for comfort first and foremost and this is another area it excels. The damper set-up ensures the Corolla soaks up speed bumps, nasty potholes and whatever else our shoddy roads can throw at it. At no point in my seven days with the Corolla did I complain about a harsh bump or thud.

Steering has a mechanical feel but it is still sharp, adding to the ‘chuckable’ vibe of this hatchback.

The powertrain can be noisy when pushed and combined with a CVT auto it’s the nicest sounding engine out there. Also, the transition from electric to petrol power isn’t particularly smooth. Other carmaker’s hybrid offerings - like Honda for example - are close to seamless. 

Some road noise gets into the cabin but it’s no deal breaker.

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 i3 scored a maximum five ANCAP stars when it was assessed at the time of its local launch in 2014, and the standard safety spec has been boosted since then.

Active tech includes ‘the usual suspects’ such as ABS, EBD, and ESC, as well as city-speed AEB (with 'Forward Collision Warning', and  'Traffic Sign Recognition'). reversing collision avoidance, a reversing camera, and tyre pressure monitoring.

If all that doesn’t prevent an impact, passive safety tech includes, dual front, side chest and side curtain airbags.

There are also top-thether points and ISOFIX anchors to secure child seats/baby capsules in both rear seating positions, as well as a first aid kit and warning triangle..

The Corolla is covered by Toyota’s five-year/unlimited kilometre warranty, which, given Kia, MG, GWM, Jaecoo and more have longer terms (not to mention Nissan and Mitsubishi’s conditional 10-year terms) is now officially trailing its competitors.

However, the capped-price servicing plan of up to five years costs just $250 for each service, which is incredibly competitive. The service schedule is every 12 months or 15,000km, whichever occurs first.

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)
