Mercedes-Benz GLS-Class vs Cupra Ateca

What's the difference?

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

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.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

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.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

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 GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

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.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

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.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

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.

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.

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.
