Mercedes-Benz GLB-Class vs Cupra Ateca

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 Cupra Ateca V is a much needed more affordable way into this small SUV while still offering a high-end feeling with plenty of standard features. Yes, the V isn't as high-powered as the VZx but it's still great to drive in the city and on the open road. Big on the inside and small on the outside the Cupra Ateca can perform urban and (small) family duties well.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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.

Once you know the Cupra Ateca V is closely related to the Volkswagen Tiguan and Skoda Karoq you can definitely see a resemblance. Still, all three have their own look with the Cupra clearly given the role of being the fierce, sporty one. 

While the Ateca V doesn’t have the same menacing styling as the VZx, it’s definitely a seriously sporty looking SUV with its 19-inch alloys, aggressive front bumper, triangular LED running lights and blacked out wing mirrors, roof rails and CUPRA lettering across the tailgate. 

The bronze Cupra logo really signals the sporty intent of this brand and I’ve been told on more than one occasion that it looks like a biohazard symbol by people confused by what it is I’m driving. According to Cupra the blade-like design represents “the sense of belonging to a clan”. 

Measuring 4381mm long, 1841mm wide and 1625mm tall with 2630mm wheelbase the Ateca V is about 15cm shorter in length than a Tiguan, but as you’ll see in the practicality section the interior dimensions might be larger than you think.

The Ateca V’s cabin is full of dark-coloured materials with black leather upholstered sports seats and steering wheel. In the same way it feels like Batman designed the exterior the interior it has a ‘Made in Gotham City’ feel with a brooding style incorporating high quality textures and surfaces.

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 Ateca V is only about 4.4m long which is a lot shorter than a Kia Sportage, Nissan X-Trail or Subaru Forester, which are truly mid-size SUVs. So, the Ateca is a small SUV but on the larger side compared to say a Volkswagen T-Roc.

Despite its fairly diminutive exterior proportions the Ateca V has excellent storage and is remarkably spacious. If you have a young, small family and want a five-seater SUV big enough for them but small enough to make urban driving easy the Ateca V ticks both boxes.

Up front there are the gigantic door pockets, two cupholders, a decent-sized covered centre console bin and under-dash storage with wireless phone charging and two USB ports.

The second row is incredibly spacious for a small SUV with so much room for me at 189cm tall to sit behind my driving position. Headroom is excellent, too.

There are also cupholders in the fold-down armrest, two USB ports and big door pockets.

The back door apertures are tall and wide which makes getting little kids in and out of their car seats easier for parents.

A 485L cargo capacity is large for the class and under the boot floor is a space-saver spare wheel.

The Ateca model now has a lower priced grade called the V and it lists for $51,990. That’s more than $10K less than the top-of-the-range VZx  which has been out for a couple of years and lists for $63,490.

The Ateca V might be less expensive but the features list is still impressive. Coming standard are 19-inch alloy wheels, sports bumpers, LED headlights, running lights and puddle lights. There’s a proximity key and power tailgate with gesture control, too. 

Inside black leather upholstery is standard, so are heated front seats and steering wheel, there’s dual-zone climate control, a power driver’s seat, a 9.2-inch media display with wireless Apple CarPlay and Android Auto and wireless phone charging. 

As for options, you can have a panoramic sunroof for $1850 and premium metallic paint for $490.

There’s also the optional 'Tech Package' for $2950 bringing a Beats stereo system and a 360-degree camera. But the best thing about the pack is it also adds dynamic chassis control which adds adaptive suspension, so when you select 'Comfort' mode the suspension becomes softer, and in 'Sport' mode the suspension firms for better handling.

Rivals to the Ateca V include the Lexus UX and Volvo XC40 but also its Volkswagen Group cousins such as the Skoda Karoq and VW Tiguan R-Line.

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 Ateca V has a 2.0-litre turbo-petrol four-cylinder engine making 140kW and 320Nm. That’s a step down in output compared to the VZx’s 221kW and 440Nm, but the V doesn't feel underpowered.

A seven-speed dual clutch automatic transmission shifts gears lighting fast with the drive going to all four wheels. Yes, it’s all-wheel drive.

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.

Cupra says that after a combination of open and urban roads the Ateca V should use 7.1L/100km. That’s not hugely fuel efficient and urban consumption of 8.6L/100km will mean higher fuel bills than a hybrid SUV of this size.

On the launch we saw a fuel consumption average of 7.7L/100km and that’s after city roads, motorways and country roads.

Once we have the Ateca V in our CarsGuide garage we’ll be able to perform a real-world test of its fuel consumption.

The Ateca V has a 55-litre fuel tank and requires 95 RON premium unleaded petrol. Theoretical driving range is around 775km.

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 launch of the Ateca V saw us drive the V and the VZx back-to-back, which highlighted how good the V is for the money when it comes to its on-road performance.

The 2.0-litre engine is superbly responsive with loads of torque for such a small petrol SUV, while the dynamics were equally impressive on winding country roads. Even when those roads occasionally and suddenly turned from bitumen to dirt at 100km/h excellent all-wheel drive traction kept everything under control.

The Ateca V we tested has the optional Tech Package fitted which adds dynamic chassis control and adjusts the suspension in the Comfort drive mode setting to a softer level compared to the firmer level in Sport. The ride in any mode, however, is comfortable with great handling. 

As standard the Ateca V is given sports suspension and after a quick sample of the Ateca V with this set-up I also found the ride to be comfortable and composed.

There's good visibility even through the rear window, along with nicely weighted accurate steering and a good pedal feel under my feet make the Ateca V effortless and enjoyable to drive.

The Cupa Ateca V hasn’t been tested by ANCAP and the Euro Ncap result of five stars (which is the maximum) has now expired because it was so long ago (2016).   

Still, while much of the safety tech isn’t as cutting edge as some new SUVs , there’s AEB, adaptive cruise control, lane keeping assistance, rear traffic alert plus front and rear parking sensors. 

The airbag count runs to seven, including a front centre bag to minimise head clash injuries in a side-impact.

For child seats there are three anchor points and two ISOFIX mounts in the back.

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 Ateca V is covered by Cupra’s five-year, unlimited-kilometre warranty, with servicing needed every 15,000km or annually.

You can buy a five-year service plan for $1990 - which isn’t overly pricey.
