Mercedes-Benz G63 vs Cupra Ateca

What's the difference?

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

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.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

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.

The G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

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 G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the 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.

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

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.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.

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.
