Mercedes-Benz GLB-Class vs Volkswagen T-ROC

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.

So that’s the T-Roc, a bit of Euro style that’s still priced to take the fight to some small SUVs from Japan or Korea.

Is it the cheapest style-forward small SUV you can get? No, but it’s far from the expensive end of things.

Plus, if you can resist ticking some option boxes, it beats some value-focused rivals and looks good doing it.

If the feeling of a sturdy fit-out and a confidence inspiring drive is important to you, I reckon the T-Roc should be an entry on your shopping list.

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.

The T-Roc subtly stands out without being garish, avoiding becoming part of the highway or suburban camouflage without relying on extreme design decisions.

For example, the LED daytime running lights that wrap around the shapes below the LED 'I.Q' headlights where vents would otherwise be on the R performance variant are quite cute.

In fact, the whole front end of this small SUV has a friendly look, even if there’s nothing specific that’s particularly exciting about it.

This 'Petroleum Blue Metallic' colour is a $700 option, but anything other than white costs extra.

However, the black roof two-tone look is a standard for the Style, as are the black mirror caps and its 18-inch alloys.

There are roof rails up top, tinted privacy windows for rear passengers and for the rear window and a sloping roofline at the rear that adds a touch of ‘sport’ to the silhouette along with a small spoiler at the top.

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.
 

Inside the T-Roc is a bit of an interesting dichotomy.

Some of what’s in here is ‘old-gen’ Volkswagen stuff, but it still holds up today against even some recently introduced models.

The dichotomy is that while it’s very usable and slick, some of its materials and surfaces let it down a touch.

The good points are that the cabin tech is a perfect level of physical and digital. The buttons and controls are easy to use and feel solid and even though the climate controls could be more physical, they’re still good as far as touch panel style controls go.

The older VW gear is arguably better than a lot of what’s found in newer models where some use of touchscreens and haptic panels has drawn negative feedback from customers.

The multimedia software managed via the 8.0-inch touchscreen is more simple and sensible than the new version, plus the Digital Cockpit Pro display for the driver is clear and, importantly, customisable. It’s a similar cockpit system that used to seem quite impressive in high-end Audis.

But what doesn’t feel very high-end is some of the plastic and the decisions around function in the rest of the space.

The leather on the seats is not a cheap option box to tick at $3450, but it feels a little cheap to the touch. It’s a tad hard and even has a bit of a rough look to it.

That option also makes them heated and electrically adjustable, though, which is welcome in winter. Otherwise, cloth seats without the optional leather or heating would be absolutely fine, and that means you get a storage space under them, too.

This central space between the driver and front passenger, too, is a little awkward with the cupholder placement. It’s behind the shifter meaning a tall bottle will be in the way and it’s got slightly odd sizing for bottles or cups with nothing to stop them wobbling.

I am, however, a fan of the angled-away phone slot under the climate controls to minimise phone screen visibility (and distraction) and the traditional shifter itself is welcome.

Look up, and (in our test car) there’s an optional ($2000) panoramic sunroof there. It’s yours if you want it, and it does have an electric blind, but some Japanese and Korean cars at this price point get that as standard.

An average-sized adult will find the second row is spacious enough and relatively comfortable. There’s an armrest, dual-directional vents and two USB-C ports.

Behind that, boot space is generous at 445L with the seats up thanks to an adjustable floor, which is very useful for tall items and even manages to fit a space saver spare tyre under it.

It’s a total of 1290L with the split-fold seats down, too, though they’re not super flat with the adjustable floor down.

The specific Style test vehicle being reviewed here is priced at $38,890, before on-road costs. But it's worth noting a new example of the Style will cost you $39,790 at the time of writing, as its price has since ours was 'delivered'.

While the Style features some older VW fitout, it comes with a decent list of features.

A set of 18-inch wheels, self-levelling headlights (with cornering function), some cute LED DRLs plus chrome highlights with black contrast trim are the best way to spot a Style from the outside.

Inside, there’s an 8.0-inch touchscreen for multimedia paired to the driver’s 'Digital Cockpit Pro' display.

The multimedia screen is last-gen VW gear, but that’s not a bad thing.

There’s also dual-zone climate control with an allergen filter, ambient lighting, a six-speaker sound system, wireless phone charger and wireless Android Auto and Apple CarPlay.

There are a few options on our test car that nudge the price up quite quickly, like the metallic paint, leather upholstery, sunroof, plus the keyless entry or ‘Easy open and close package’.

All this brings the total price as-tested to $45,640, before on-roads.

The good news is you don’t need to tick all, or any, of those options for this to still be a compelling option. 

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 engine in the T-Roc - as with most Volkswagens - does what it says on the tin. Essentially, a 110TSI means there’s 110kW of turbocharged VW happening, in this case a 1.4-litre four-cylinder that also makes 250Nm of torque.

It’s paired to an eight-speed torque converter, which will be music to the ears of those who have been scorned by older VW dual-clutches.

It drives the front wheels only, and there’s no hybridisation or 48-volt system.

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.

A lack of electrification in a relatively small engine and a traditional drivetrain shouldn't scare you too much, in this case.

Combined cycle fuel consumption is a claimed 6.3L/100km. On test in mostly urban areas or for spirited driving we saw the fuel use rise a little higher than that but not by as much as you might think.

After a mix of primarily urban, some highway and a stint of dynamic test driving, the trip computer admitted to a figure of 8.1L/100km.

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.

The T-Roc is essentially a previous-generation Golf-turned-small SUV in terms of its platform, and that’s a great thing for anyone who likes driving.

The Golf 7.5 was a benchmark for everyday driving as far as hatchbacks are concerned, and even though the current Mk8 might be a bit more up to date, the T-Roc’s use of the platform it rides on is practical and fun.

It’s not as nimble as a Golf, but the T-Roc in front-drive Style guise, with a responsive turbocharged engine and no all-wheel drive system weighing it down, is not only more dynamically capable than most rivals, it’s also easy to access that capability.

The 1.4-litre engine feels well-tuned for its two modes accessible through the shifter - calm but not lazy in ‘Drive’ and eager but not thrashy in ‘Sport’.

It works well with the transmission on the move, picking right gears fairly accurately, though there are paddles behind the wheel for those who prefer to take charge.

The drive modes are also more customisable than just those on the shifter, with 'Individual' selections for steering and drivetrain able to be used rather than the standard 'Eco', 'Normal' or 'Sport' full-system modes.

While the steering wheel itself is a little thick and the feedback, while adequate, isn’t the most telling, it’s accurate and inspires confidence in cornering.

The T-Roc handles turn-in and exits well, even soaking up bumps and not becoming unsettled when braking.

Its safety systems are relatively subtle, and the active cruise control is well sorted, though the automatic braking at car park speeds can be overzealous. Something I’ve experienced in VW Group models several times over the years.

The main culprit for the T-Roc was a shrub beside my driveway that, while not touching the car, would set off the automatic braking system. Still, better than letting the car roll back if there was a proper obstacle or someone who could be hurt in the way.

Aside from that, the Volkswagen T-Roc is fun and easy to drive, and the work that’s gone into that puts its price into perspective a little more.

There are more expensive cars available that are less impressive, some even disappointing.

In 2017, ANCAP gave the T-Roc five stars for safety. For most people, that says enough, plus the list of features the SUV comes with is fairly comprehensive even in the Style.

While its rating is getting on in years, the only real downside to the T-Roc’s age when it comes to safety is it only having six airbags - front and side for the front passengers, plus curtain airbags for front and rear passengers.

But the list of tech isn’t lacking, with driver fatigue detection, pedestrian monitoring, parking bay and parallel parking assistance, pedestrian monitoring, side assist, rear cross-traffic alert and lane assist.

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.

Volkswagen’s five-year/unlimited kilometre warranty is pretty standard for a premium-leaning brand, with VW also offering roadside assistance for the warranty period.

In terms of servicing, VW offers care plans of three years or five years, covering servicing for $1515 or $2770 respectively. That's an average of $505 or $554 per workshop visit.

Otherwise, servicing costs at 12-month/15,000km intervals can cost from $470 for some to $1104 to the biggest service if you don’t go with the locked-in package.
