Mercedes-Benz GLB-Class vs Mazda CX-60

What's the difference?

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

The Mazda CX-60 GT P50e will suit those families that don’t need the extra seats of its bigger siblings but still want some luxury and comfort. I like the features and the hybrid efficiency but don't like how it handles in the city. I got used to it but it’s not my favourite plug-in hybrid to drive and for the higher price tag, I did expect a smoother experience.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

For me, Mazda SUVs are a bit too similar to get me excited. It’s a case of ‘same same but different’ when they’re on the road.

Each one looks like a scaled version of the other but the GT’s body colour extends to the lower cladding and wheel arches, which makes it appear larger than the CX-5 at least.

The GT model is also set apart from the base Evolve model with the heavier use of black accents – like the gloss black side mirrors, 20-inch alloy wheels and honeycomb grille. It’s 'PHEV' and 'In-line 6' side badges are also blacked out for added sportiness.

Full LED exterior lights in Mazda’s classic slim-line look plus some added ‘in-take’ vents at the front complete the overall package.

In the cabin, there’s a strangely wide panel on the dashboard that separates the centre console from the media system and it doesn’t look right compared to the skinny air-vents and button panel that sits below it.

The interior does sport black leather-accented trims and enough soft touchpoints that there is a sense of quality throughout but I was hoping for a more luxuriously-appointed interior, given the price tag. Especially considering the top-spec CX-5 model is a good $25K more affordable.

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

The cabin is practical with its great sense of space in both rows, which is not always the case for a mid-sized SUV. Taller families will love how much legroom there is to be had.

The front passenger can get comfortable with the eight-way power adjustments on their seat but the driver enjoys the most perks with 10-way adjustments, lumbar support and two-position memory function.

Both seats have heat function (up to three levels) and are well-cushioned for a longer trip.

The rear seats are well-padded and feature a handy 40/20/40 split-fold for internal storage. The outboard seats also have a heat function for added comfort.

My six-year old found this car to be super easy to get in and out of because of the 175mm ground clearance. He also enjoyed a good view from the wide windows and liked the amenities, like the directional air vents and reading lights.

Individual storage is decent in both rows but the front passengers get the best options with two cupholders, extra-large storage bins in each door, a glove box and a middle console, which is on the shallow side.

Back seaters get two cupholders in the fold-down armrest, small storage bins in each door and a couple of map pockets.

The technology looks upmarket with the dashboard being headlined by two separate 12.3-inch digital screens.

The multimedia system is easy enough to use but I wish Mazda enabled touchscreen access on this as it’s a pain to use the rotary selector dial while on the go.

That said, it’s fab that you get wireless Apple CarPlay and wired Android Auto, plus built-in satellite navigation.

The premium Bose sound system with its 12 speakers makes for a concert-like experience and the charging options are good throughout the car.

Up front you get two of the faster USB-C ports, a 12-volt socket and a wireless charging pad to choose from.

In the back seat you get another two USB-C ports plus a handy 220-volt (150W) port for bigger items. In the boot you get another 220-volt port but this one has 1500W capacity, so larger appliances can be hooked up.

The boot rounds out the cabin practicality with a decent 477L of capacity but you can bump it to 1726L if you fold down the rear seats. There are manual levers in the boot to do this.

The level load space makes it easy to slide things in and out and I always enjoy having a powered tailgate. A flipside to all of this room though is that you only get a tyre puncture repair kit rather than a physical spare.

There are three models for the CX-60 and ours is the mid-spec model, which will cost you $80,300, before on-road costs.

You get a decent number of features in this grade, so it feels well-positioned against its rivals.

The Lexus NX350h F Sport Hybrid AWD beats it by a smidge at $80,500 (MSRP) and the Volvo XC60 Recharge Plus sits well above at $92,990 (MSRP).

As you’d expect there are some luxury items to be found, like the panoramic sunroof, heated front seats, heated leather steering wheel, and heated rear outboard seats.

You also enjoy the following as standard - dual-zone climate control, electric front seats, leather-accented trim, electric steering wheel adjustment, satellite navigation, keyless entry, a hands-free powered tailgate and a 360-degree view camera system plus a bunch of upmarket technology which we’ll touch on later. 

The GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

The GT P50e has a 2.5-litre, four-cylinder petrol plug-in hybrid powertrain with a maximum power output of 241kW and 500Nm of torque.

This is an all-wheel drive and has an eight-speed auto transmission.

Overall, it’s fairly gutsy and you’ll be pleased with that power when you hit the open road.

On the electric motor side of things, this also has a lithium-ion battery with a relatively small 17.8kWh capacity which gives you a driving range of up to 76km when in pure EV mode. 

It has a Type 2 AC charging port but it can’t be hooked onto a fast charger as it lacks the CCS DC connector.

On a 7.0kW system you should be able to get from 20 to 80 per cent in as little as 90 minutes. The household plug charging time is more like seven or eight hours, so best to leave overnight when at home.

The GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

The official combined cycle fuel figure is 2.1L/100km but after an almost 600km roadie and charging it twice, my real-world usage came to 6.4L.

That's a good result considering this car's power and size but you will get the best efficiency if you charge the battery regularly. 

Based on my usage and the 50L tank, I’d be able to get a rough driving range of 781km.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

Well .. let’s unpack that shall we? Yes, this thing certainly has power but the biggest surprise for me was how the electric motor and combustion engine talk to one another because it doesn’t make for the smoothest driving experience in the city.

Therein lies the rub, for me. At this price point I was hoping for a smoother drive experience. In fact, it performs in the strangest of ways - when you’re accelerating, it feels like you’re in a much lower gear than you ought to be.

Almost like you’re stuck in 4WD. There is a sensation of the engine being held back and fighting you when you drive this in built up areas.

The ride comfort in the city was affected by this because it has a tendency to bunny hop/lurch when you hit corners at lower speeds. However, it has beautiful manners on the open road and that is where this model shines for comfort and handling. 

In this environment the steering feels concise and you can handle winding roads at speed without much roll. It can get a little noisy in the cabin as the electric motor wheezes a lot but otherwise, it’s alright for highway driving.

Overall, it's pretty good to park and I like the tight 10.8m turning circle. The 360-degree camera system is clear, too, but coupled with the front and rear parking sensors, you won’t have any issues.

The CX-60 has a lot of safety features I like to see on a family car and a highlight is the intelligent blind-spot monitoring system which shows the vehicles around you in a dynamic display on the instrument panel.

Other standard safety features include LED daytime running lights, lane departure alert, lane keeping aids, rear cross-traffic alert, forward collision warning, intelligent seat belt reminders, a driver fatigue monitor, front and rear parking sensors and a 360-degree view camera system.

It also has adaptive cruise control but it was a bit hit or miss. It’s quite sensitive and sometimes registers a larger vehicle, like a truck, as still being in your lane despite overtaking.

It has autonomous emergency braking with car, pedestrian, cyclist and junction assist detection that’s operational from 10–80km/h (although the car detection is operational from 4.0–160km/h).

I’m happy to say this system works well – a ‘roo jumped out in front of me this week and the car performed an emergency stop with plenty of room to spare.

It achieved a maximum five-star ANCAP safety rating from testing done in 2022 and it has eight airbags, including a driver’s knee- and a front centre airbag.

There are ISOFIX child seat mounts on the outboard seats and three top tethers and while two seats will fit best, you might get lucky with three skinny booster seats. There’s also plenty of room when a 0-4 rearward facing child seat is installed.

As with all Mercedes-AMG models, the GLB35 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

The GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.

The ongoing costs are pretty reasonable. It comes with a five-year/unlimited km warranty which is usual for the class. It also has capped-price servicing for five-years or up to 75,000km, whichever occurs first.

Services cost an average of $518, which is a little expensive for this class but servicing intervals are fine at every 12 months or 15,000km, whichever occurs first.
