Lexus UX250H vs Mercedes-Benz GLC300

What's the difference?

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.

The GLC300 Coupe isn't quite as great when it comes to being a family car as the regular SUV version of the GLC, and that's purely down to the sloping roofline which not only makes access more difficult to the second row but reduces boot capacity.

That said, the GLC300 Coupe makes a much better family car than a Mercedes-Benz C-Class sedan, or any sedan.

Easy and enjoyable to drive, packed with great features and still practical, the GLC300 Coupe would still cut it as a good family car.

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.

Coupe SUVs aren’t for everybody… they’re not even for lots of people. But the design of an SUV with its roof cut down so that it meets the tailgate at an almost sportscar-like angle appeals to more than a few fans. The thing is they don’t just like the look, they love it, and they also probably enjoy how much the styling makes other people cranky.

To my eyes the GLC300 Coupe is the best execution of the bodystyle compared to those of BMW and Audi. There’s an elegance to the GLC300 Coupe and the AMG-line adds a tough look that only enhances the solid, powerful but pretty look.

The GLC Coupe is a mid-sized SUV and this new generation model is a bit bigger the previous one and now measures 31mm longer at 4763mm end to end, it’s 1890mm wide, 1605mm tall and has a wheelbase of 2888mm.

It’s also more aerodynamic than ever. No seriously, it’s drag coefficient is now 0.27 and it looks like a bar of soap - and it's about as slippery as one, too.

More curved surfaces await inside with a dashboard that pours down into the large centre console and it's adorned with a sloping and large portrait-style media screen. 

At night or in tunnels the ambient lighting glows through the air vents and skirts the edges of the door trims, console and dashboard.

It’s a minimalist and high-tech cockpit with modern sports seats up front and a Nappa leather wrapped steering wheel with its twin blade design.  

So, how does the coupe design work for family practicality? Let’s take a look.

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.

SUVs are the most practical cars for families because of the better access to the cabin thanks to their large doors and slightly elevated ride height, their big boots with wide and tall hatch openings and their high flat rooflines. They’re essentially raised station wagons.

A coupe-style SUV still has four doors but they are less boxy due to the sloping roofline which falls away quickly to meet the tailgate at a lower point. The effect is a sporty-looking shape but practicality is lost in this exercise of form over function.

The second row doorways aren’t as large as those on the regular SUV. I did a side-by-side test and felt like I had to duck under the sloping roof when getting out of the back seat.

The smaller opening also made it trickier to lift my toddler daughter into her baby seat.

The sidesteps are also surprisingly handy for bigger kids and my eight-year-old used them every time when climbing into the car.

Cabin storage is outstanding with huge door pockets and cupholders in both rows, and while the 545-litre boot in the GLC300 Coupe is 80 litres smaller than the cargo capacity of the regular GLC SUV, it's bigger than the previous version of the Coupe.

As for people space, there’s enough headroom for me at 189cm tall in the back seat and heaps of legroom, even behind my driving position.

I’ve mentioned the lack of climate control in the second row, but also should point out that there are no USB ports back there either.

There are USB ports in the big centre console box upfront and a long cord should be able to make it to the second row. 

There’s a wireless phone charger but it's housed in the bowels of the centre console too, and you’ll need to weave your hand while clasping the phone under the shiny black trapdoor, past the cupholders possibly with drinks in them and almost under the dashboard.

Mercedes-Benz is offering Australia just the GLC300 grade in both the SUV and Coupe body styles.

High-performance AMG variants are out overseas now and will arrive in Australia soon, too.

You can expect to pay more for these AMG beasts - a lot more than the $113,900 list price of the GLC300 Coupe.

Still the GLC300 Coupe does come standard with an AMG Line body kit and 20-inch AMG alloy wheels. LED headlights are also standard, so is the panoramic glass roof, tinted rear glass, proximity unlocking and a power tailgate.

Inside there’s synthetic leather Artico upholstery, sports heated front seats, Nappa leather steering wheel, an 11.9-inch media display with Apple CarPlay and Android Auto, a 12.3-inch digital instrument cluster and a head-up display. There’s also dual-zone climate control and wireless phone charging.

The value is good in terms of features, although the price is slightly higher compared to the rivals such as the BMW X4 xDrive30i ($106,400) and Audi Q5 Sportback 55TFSI ($110,200).

It’s worth pointing out, too, that the GLC300 Coupe is about $10K more than the GLC300 SUV version. Why? The coupe versions of prestige SUVs always tend to be pricier than their regular more boxy SUV siblings. Somebody in marketing will be able to explain why.

Having lived with the GLC300 Coupe with my family over the past few days I can say the proximity unlocking which works by touching even the back door handles is excellent, the tinted windows are dark and cut out much of the sun's glare, but there’s no climate control in the second row. There are air vents back there, which is good.

I found that on hot days the semi-transparent shade on the glass roof couldn’t stop the cabin from heating up quickly.

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.

The GLC300 Coupe has a 2.0-litre four-cylinder turbo-petrol engine making 190kW of power and 400Nm of torque.

There’s also an overboost function which allows the engine to make an extra 17kW and 200Nm just for a brief moment, but that extra dollop of grunt combined with the regular output provides impressive acceleration (0-100km/h in about 6.3 seconds) for overtaking or moving quickly when you need to.

A smooth nine-speed automatic transmission sends the drive to all-four wheels.

The GLC300 Coupe is all-wheel drive and while there’s a setting for rougher terrain, along with one for comfort, eco and sport, but I’d make sure that it doesn’t get any more adventurous than tame gravel and dirt roads.

Mercedes-Benz refers to the GLC300 Coupe as a mild hybrid and this is because it has a 48-volt system and an integrated starter-generator.

This type of hybrid doesn’t use electric motors, doesn’t drive the wheels and won’t save much fuel, but it will provide efficiencies by supporting the engine and when coasting, plus will reduce petrol consumption to a small degree.

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.

As we mentioned above the GLC300 Coupe's 48-volt mild hybrid system is not the kind of hybrid that will allow you to drive miles on electric power, nor will it dramatically reduce fuel consumption in the way a parallel, series or plug-in hybrid will. But every bit of efficiency helps.

Mercedes-Benz says the GLC300 Coupe will use 7.7L/100km after a combination of open and urban roads. 

We had the GLC300 Coupe for just two days, but in that time my family covered 176km of regular daily usage which took in motorways but mainly suburban duties such as the school run, supermarket dashes, that sort of thing.

In our fuel test we measured 14.48 litres at the fuel pump which works out to be an on-test fuel use figure of 8.2L/100km and not far off the manufacturer’s claim. 

While this fuel consumption isn’t overly high, a plug-in hybrid or even a parallel or series hybrid could return about 5.0L/100km or less.

Mercedes-Benz has dropped plug-in hybrids from its Australian range which is a shame because it would be good to see more efficient options in the GLC range. Of course if you want more efficiency from a Benz of the same size, there is always the fully electric EQB or EQC.

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.

There’s a lot to like here but the short version is the GLC300 Coupe has a comfortable ride, but good handling, with a responsive engine, although rear visibility through the small back window is poor.

If we drill down a bit further I can tell you that excellent cameras around the car will help you check to make sure kids aren’t running around behind you and that forward and side visibility through the window is good.

An important takeaway is that the GLC300 Coupe is easy to drive with light steering and an engine that’s mild and controlled in its power delivery.

The gear shifter is mounted on the steering column, in the same way an indicator lever is. So putting the car into Drive, Reverse and Park is so easy and means you don’t have to take your hands off the steering wheel. 

As a family car I liked the good body control and composed ride. We have a small toddler that we can sometimes only get to sleep by taking her for a drive and we found that she could nod off and not be woken by potholes and speed bumps or too much leaning in the corners. 

The GLC was given the maximum five star ANCAP rating in 2022. There’s AEB, active lane keeping assistance and active blind spot warning and nine airbags including a centre airbag.

As mentioned above I especially liked the surround-view camera systems - which let you look right around the car - good for driveway safety and kids.

For child seats you’ll find two ISOFIX mounts and three top tether anchor points in the second row.

I was also impressed to see a space-saver spare wheel under the boot floor and not just a puncture repair kit. 

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