BMW I3 vs Lexus UX250H

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. 

Most cars get worse as they age as their makers try and save pennies by scrimping on quality and features. But the reverse seems to be true for the Lexus UX.

The 250h Luxury 2WD we tested is the car that the brand should have launched with back in 2018, with an appealing balance of performance and economy, comfort and sporty handling, as well as refinement and features. The UX has finally come of age.

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. 

A hefty portion of the UX’s engineering underneath is shared with the popular Toyota C-HR. Not that you would necessarily know that by glancing at it.

Even five years on from launch, the current model looks slick and contemporary, and it seems to have informed the styling of newer, larger Lexus SUVs like the latest NX.

Not that you’d call the UX an SUV – it’s very much a higher-riding hatchback, with a ho-hum 160mm of ground clearance.

To put that in perspective, other crossovers are taller: the GLA has 213mm, while Subaru’s new Crosstrek boasts 220mm. At least the UX’s is loftier than the C-HR and its pitiful 137mm.

That said, the angular wheel arches and wide-track stance serves the Lexus well.

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 UX’s compact crossover-esque hatchback proportions have implications inside. Inevitably, this is no larger than the (related) Toyota Corolla, despite having the higher seating position.

Beyond that, though, the 2023 model highlights how Lexus has made its so-called ‘gateway’ model better than before.

For starters, despite being the base grade, this UX has a properly premium ambience, backed up by exceptional fit and finish.

From a sensory perspective, the UX looks, smells, feels and sounds like a Lexus should. And by the latter, we mean the cabin is pleasingly isolated from the outside world.

The overhauled touchscreen and multimedia system is a huge step forward for the series. The larger new display looks great and works well – what a monumental improvement over the infuriatingly fiddly old set-up. It’s difficult to see how they’ll improve it. Dependable and glitch-free. Are you listening, all European manufacturers?

Meanwhile, the carryover parts that worked well enough before continue to impress.

The UX’s front seats are sumptuous in their cushy softness and comfort, yet provide sufficient support over longer driving distances.

There’s also the excellent driving position, with most switchgear within grasp. There’s just enough space for taller people to settle in nicely up front. And the basics like ventilation and storage are thoughtfully executed. The climate in the UX is always fine.

Negatives? Don’t worry, we’ve identified several.

As mentioned earlier, the now-better-equipped Luxury does have all the essentials. But for a car that’s approaching $60K-drive-away, we’d expect kerb-side mirrors that dip down when reversing to avoid damaging alloys against gutters; we couldn’t get ours to auto-fold when locking up, either.

Driver vision out isn’t great. Thick pillars and that rising shoulder line make changing lanes and reversing a technology-reliant affair, as it’s difficult to see objects that are too-easily obscured. For the same reasons, a front camera would be useful in this grade.

Others might expect a sunroof, or cooled seats that massage, or a head-up display for the instrumentation, but we’d argue that they’re hardly necessities. Lexus has to upsell buyers to something.

Moving on to the back-seat area betrays the UX’s compactness most.

The back doors have small apertures. Entry/egress is challenging for folk with long legs. Legroom is tight, and three adults abreast would be a struggle, so it’s best to treat the littlest Lexus crossover as a four-seater.

Yet headroom is fine, the appearance and finish remain first class as it is up front, and the basics are all present – air vents, grab handles, coat hooks, overhead lighting, one map pocket, centre armrest with cupholders, two USB outlets, and windows that wind all the way down. Narrow front seats aid with light, vision and ambience, too.

Further back, the luggage area is pretty petite for an SUV, though the boot is (slightly) larger than the Corolla and Mazda3’s. That powered tailgate is useful if your arms are full, but the loading lip is high.

Normal boot floor depth is shallow but most of that flooring can be removed to reveal a hidden compartment underneath.

Small side pockets are also useful. You’ll find a 240V outlet. Bag hooks and floor tie-down hooks are fitted.

And – being a hybrid – there’s no spare wheel, just a tyre inflation kit. And the flimsy cargo cover is there only to keep prying eyes out.

Not big on utility, then, but the UX is true to its role as a Lexus in concentrate form.

Let’s list those changes briefly, as they inform the car you see before you.

The pre-facelift UX released in 2018 was criticised for riding too harshly and not being fun enough to drive.

So, Lexus says the MY23 version’s steering rack is better braced, the suspension and rear adaptive dampers have been retuned, the chassis gains more spot welds for added rigidity and the body is now stiffer and stronger than before. These are learnings directly applied from the UX300e EV version released in late 2021.

Most buyers will probably be more impressed with a now two-inch larger touchscreen, updated and (at long last!) easier-to-operate multimedia system, post-crash emergency services-callout should the driver end up incapacitated, upgraded voice recognition system, more-effective lane-keep assistance, improved traction through corners, better surround-view monitor and jazzed-up trim presentation.

Collectively, they strive to finally bring the expected/demanded on-brand qualities lacking from the previous model and in the UX’s largely-patchy competitor set – namely the Audi Q2, BMW X2, Jaguar E-Pace, Mercedes-Benz GLA and Volvo XC40. 

This is especially so when sizing up the entry-level front-wheel drive grades (euphemistically dubbed 2WD at these exalted heights) of each, as we have done with the least-expensive hybrid version of the UX, the 250h Luxury from $53,820 (all prices are before on-road costs).

Costing nearly $8000 more than the base 200 Luxury petrol version, the hybrid accounts for the lion’s share of sales, and really has no direct electrified premium rival at that price point, except in the recently-released Alfa Romeo Tonale Ti from $49,900 – though that’s a mild-hybrid set-up with a 48-volt battery.

Along with an electric motor and a small Nickel-metal Hydride (Ni-MH) battery, the 250h Luxury is compellingly equipped for a base grade, including a 12.3-inch touchscreen, wireless Apple CarPlay, wired Android Auto, Bluetooth telephony, ‘Hey, Lexus!’ voice recognition, 10-speaker audio, digital radio, satellite navigation, remote engine-start/door-unlocking/hazard flashers/buzzer, acoustic windscreen glass, heated/powered mirrors, powered steering column, heated/powered front seats, climate control, keyless entry/start, a powered tailgate, roof rails, alarm and 17-inch alloys.

The 250h Luxury also comes with ‘Enhancement Pack 2’, featuring a powered tailgate with kick sensor, a wireless phone charger, cornering lights, headlight cleaners and rear privacy glass.

On the safety front, there’s all the usual driver-assist tech equipment including Autonomous Emergency Braking (AEB), lane-support systems and rear-cross traffic alert, amongst other items. Check our safety section for a full rundown.

So, yes, the UX 250h Luxury represents strong value. Even for a luxury-branded vehicle.

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 UX’s Corolla/C-HR connection continues with its 2.0-litre (1987cc) twin-cam four-cylinder petrol engine, delivering 107kW of power at 6000rpm and 188Nm of torque between 4400 and 5200rpm.

The 250h Luxury pairs that with an 80kW/202Nm permanent magnet motor and 1.4kWh Ni-MH battery, for a combined power output of 135kW. A second, rear-mounted motor is available in higher grades, providing all-wheel drive. But not in this Luxury guise.

As with most Toyota and Lexus hybrids, charging is only via the petrol engine and recuperated energy from braking. Electric-only drive is only offered during brief spells of low-speed light-throttle driving, or off-throttle coasting where conditions allow.

Drive is sent to the front wheels via an electronically-controlled continuously variable transmission (CVT). Three modes are offered – 'Eco', 'Normal' and 'Sport'.

Tipping the scales at 1625kg (kerb), the 250h Luxury offers a power-to-weight ratio of nearly 83.1kW per tonne. That’s a hefty output for a hybrid. Top speed is 177km/h, with 0-100km/h needing 8.5 seconds.

Underpinning that performance is a MacPherson-style strut-front and a multi-link rear suspension set-up.

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, the 250h averages an impressive 4.5 litres per 100km on the combined cycle, which is just 103 grams per kilometre of carbon-dioxide emissions.

Now, out in the real world, with plenty of inner-city and urban driving as well as a spell of fast highway runs punctuated by some very heavy-footed acceleration, we managed just under 7.4L/100km pump-to-pump.

That’s not too bad given how hard our UX was caned. The trip meter showed 5.6L/100km over the same distance (nearly 400km).

This is one Lexus hybrid that will happily sip from the standard 91 RON unleaded petrol pump. With a fuel tank capacity of a smallish 43 litres, expect a range of between 930km and 1000km.

For a luxury small crossover, these are economical figures.

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.

Before driving the 2023 UX250h hybrid, there was some trepidation.

All versions of the original series from 2018 were tested previously, and in every one bar the base 200 on small wheels and tyres, none lived up to the promise of a premium Lexus crossover. A harsh ride, excessive noise intrusion and dull handling made this model a disappointment.

That’s all in the past, thankfully, thanks to a sustained program to save the UX from mediocrity. The company really got the basics wrong the first time around with the horrid CT200h predecessor back in 2011, so we imagine that it would be damned if this was going down the same sorry path again.

In the 250h Luxury, as reviewed here, it is difficult to objectively fault the way everything works and drives.

Let’s start with performance. Even in Normal or Eco mode, the UX steps off the line briskly, and initially at least, it’s the electric motor and battery that silently whooshes the car forward.

If you’re gentle, you can reach speeds of up to about 40km/h before the petrol engine chimes in unobtrusively.

Beyond that, there’s a stream of electric power you can feel, keeping the acceleration coming on strong, even as speeds rise above 100km/h.

This is also true for Sport mode, except that it all happens a bit quicker and earlier, and with extra urge.

And the welcome news here is that the CVT doesn’t really make the engine sound too droney, unless the driver is mashing the pedal to the metal.

Travelling along at normal urban speeds, there’s a seamless transition from electric-enhanced petrol propulsion back to electric-only if the conditions are right – such as when coasting off-throttle.

This is most common in heavier traffic, and the resulting smoothness and quietness adds to a refined and relaxed experience.

About our only objection is when you apply the brakes. In our test car, they felt a little on/off, like a switch. At times, they seemed too grabby for smooth stopping.

That said, the driver can downshift using the gear lever to provide powertrain braking, to help minimise snatchiness.

Road noise seems to be more muted than before, supporting Lexus’ claims that retuning the suspension and beefing up the structure/chassis has helped with refinement.

We wouldn’t say the UX is at the top of the class for quietness, especially on Australia’s coarse-bitumen highways, but now things have hushed sufficiently enough for a crossover purporting to be a premium.

Where the suspension changes really transform the UX, at least on the 215/60R17 tyres the Luxury wears, is how much softer and comfier the ride is.

Where before there was suddenness there’s now suppleness, substantially improving the experience. We wonder whether the bigger-wheeled rubber the richer grades receive are as well-resolved.

As the 250h Luxury is not trying to be a hot hatch, the resulting body lean through fast corners is a happy trade-off, though it’s not so roly-poly that handling composure is adversely affected.

Plus, the steering – while light and easy at parking speeds – still offers enough response and feedback for most drivers to enjoy taking the UX for a cross-country blast once in a while.

To that end, the steering’s weighting does increase in Sport mode… though you won’t be selling your Peugeot 205 GTi for one just yet, but that previous dullness is history. In fact, whether behind the wheel or ensconced in one of the inviting outboard seats, the UX250h as a whole is a much sunnier experience all-round than before.

Tested in 2019, the UX has managed an ANCAP crash-test rating of a maximum five stars. The rating applies to all models built from October, 2020, onwards.

That’s no surprise, given the level of standard safety equipment fitted, even to this entry-level 250h Luxury grade.

You’ll find eight airbags – dual front, side chest, side head and driver and passenger knee – as well as Lexus’ ‘Pre-collision safety system’ with AEB for pedestrian (day/night) and cyclist (day) detection and daytime intersection assistance.

The AEB functions from 10km/h to 180km/h and the lane support systems between 50km/h and 180km/h.

Also included is lane-keep assist, speed-sign recognition, rear cross-traffic alert, parking support braking, blind-spot monitor, emergency steering assist, auto high beam, full stop/go adaptive cruise control and front and rear parking sensors.

Anti-lock brakes with brake assist and electronic brake-force distribution, traction control, stability control, active cornering assist, four-wheel disc brakes and a reverse camera are fitted.

Lexus’ Connected Services offers SOS emergency call, stolen vehicle tracker and other GPS-based assistance features.

The outboard rear seats include ISOFIX child restraint anchors and there are three top tethers for baby capsule/child seat straps across the second row.

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)

Lexus offers a five-year/unlimited kilometre warranty and roadside assistance.

Service intervals are at 12 months or 15,000km.

The first three scheduled services are capped at $495 each, with the work carried out detailed online.
