Audi SQ8 vs Mercedes-Benz GLE400

What's the difference?

The Audi SQ8 isn’t your typical performance SUV. It’s more refined and less flashy. The tech can be more complicated than it needs to be and if you’re wanting that V8 soundscape, you won’t find it here.

However, the handling and on road experience are superb plus you can comfortably haul the family around and look good doing it.

All told, the Mercedes-Benz GLE 2020 model is an improvement in many ways over its predecessor. It's safer, more high-tech, considerably more luxurious and practical inside, and offers better value, too.

But, in 300d guise at least, it's let down by a slightly underdone engine, and suspension that just doesn't do a good enough job on rougher roads. It's close, but not close enough to be best in class.

Maybe that'll be a different case for the higher-grade versions with the most high-tech engines and the tricky optional suspension... we'll have to wait and see.

The SQ8 is a gorgeous coupe-style SUV that looks purposeful and poised with its balanced proportions and wide stance. It’s stands apart from its siblings thanks to the S-styled nose treatment and our test model's black accent package makes the honeycomb grille look even sportier. 

The update sees new air intake vents at the front, matrix LED headlights and new chrome exhaust tailpipes.

The upgraded 23-inch alloys with red calipers behind them hint at what’s under the bonnet, as does the Sakhir (sack-heer) Gold paintwork which is aptly named after the one-off Grand Prix race circuit.

The interior looks luxuriously appointed with the black Valcona leather upholstery and the dash is headlined by three high-end technology screens. The SQ8 also gets sport seats featuring a quilted design and 'S' badging but there’s not much else separating it from its siblings.

Audi fans will love the the SQ8's more understated interior but newcomers might be surprised it's not as flashy as some of its rivals.

You can make your own mind up about the styling of the new GLE. It's certainly more aggressive than the model that came before it, and Benz claims that it's the most aerodynamic SUV in its class.

The models on test were all fitted with the AMG styling pack and the bigger 21-inch multi-spoke wheels, and from some angles it's a striking car. I particularly like the way the rear-end treatment has worked for the GLE: the triangulated tail-lights, the lower bumper and the rear glass all work together well.

In profile, the GLE is quite challenging to look at. The rounded window-line is a bit awkward, and somehow the wheels just don't fit with the bulky guards (though I do like the way the AMG 21s poke out a bit at the back).

The front sees the diamond-style treatment to the grille for the AMG Line versions, but there's a lot of black plastic on the bumper, and the headlight shape gives it a bit of a droopy-eyed look. Is it just me, or is it a bit of a Bassett Hound? 

It is a bigger car than before - 111mm longer (now 4930mm - and on an 80mm longer wheelbase, now 2995mm), and it's 15mm wider but 31mm lower - and it looks more substantial as a result. I'm just not sure it's pulling off its bulk as well as it could.

So the outside is pretty, er, interesting. We had comments from passersby to that effect, too, and in our comparison test it was the consensus of our team of experienced testers that the GLE had some challenging exterior design elements.

But inside is where the best bits hide, with a lot of luxury finishes, materials and technology giving the GLE some wow factor that its exterior design arguably misses out on.

The upper large SUV tag certainly makes sense when it comes to cabin space because there's a lot of it. Both rows enjoy ample head- and legroom and access is great thanks to wide door apertures and high ground clearance.

Comfort is high with well-padded seats and thanks to the Sensory Package all but the middle back seater get some luxury extras.

The centre rear position has compromised legroom courtesy of the transmission tunnel, so it's best for a kid. However, the front seats take the cake with their massage, heat and cooling functions and adjustable supports.

Amenities are great throughout the car and the extendable sun visors, rear electric sunshades, soft-close doors and four-zone climate control clinch the practicality deal.

Individual storage is a bit sparse up front with two cupholders, a drink bottle holder in each door and a shallow middle console that realistically only fits a phone.

The glove box is a great size. I can fit my handbag in it, but there are not a lot of areas to pop your smaller items in.

Individual storage is a bit better in the rear as you get two big map pockets, a drink bottle holder in each door, plus two cupholders in the fold-down armrest - so it feels like you have more places for your bits and pieces.

Technology looks amazing but overwhelming to use until you wrap your head around it all. The haptic feedback also gets tired fast. The built-in satellite navigation is super simple while the head-up display and digital instrument cluster feature pull through directions, which is handy.

Charging options are good with each row getting two USB-C ports and a 12-volt socket but the front also enjoys a wireless charging pad. The pad is slow to charge, though, and left my iPhone feeling super hot whenever it was used.

The boot is a good size at 605L and easy to access, too. The sloping roof means larger items have to sit flush with the seats but you shouldn’t have to worry for road trips. 

The back seat has a 40/20/40 split which opens up storage options and this model has a powered tailgate.

The cabin presentation and pragmatism is excellent in the new-generation GLE. There was an existing version on site for us to compare, and to say it's like night-and-day would be generous to the old model.

A lot of that comes down to the MBUX twin 12.3-inch screens on top of the dash - one for all the driver instrumentation and controls, and the other for sat nav, media, car controls and other settings. They look great, and there are multiple ways to control them: the steering wheel controls, the touch pad between the front seats, the screen in the middle is touch-capacitive, and there's the much-bragged-about “Hey Mercedes” voice control system.

But it's more than just the screens: the finishes and materials used in the GLE are exceptional. The plastics are excellent, the brushed aluminium treatment that runs the width of the dash with ambient lighting, the surrounds on the vents (oh, so many vents!) - it all works so well together. But the open-pore wood finish is my favourite element, adding a touch of ruggedness that's also plush and luxurious.

The test cars all had the high-end leather treatment and optional bolster-heavy seats, and they're okay, but a little fiddly to adjust. I guess that's the beauty of driver profiles - the car will remember your favourite settings and make the adjustments as you get in or out by detecting the key.

There's also excellent storage throughout - the door pockets in all four doors are huge, there are cupholders front and rear, and loose item storage is decent, too. Plus there are heaps of USB-C (fast charging) ports up front and in the back.

Speaking of the back, the cars at launch all had the seven-seat package, which might appeal to you, or not. It's more than just a couple of seats in the back row, because it includes electric seat adjustment for the second row, with slide and recline functions allowing you to prioritise second- or third-row space.

The space in the second-row with the seats set as far back as they can go is excellent. There's heaps of room for someone my height (182cm) to sit behind a similar sized driver with ample knee room, headroom and shoulder room. You'll be able to fit three adults across the back, or if you have kids, there are three top-tether points and outboard ISOFIX child-seat anchors, too. No child seat restraints in the third row, though.

Whether you choose the five-seat or seven-seat option, the boot space remains the same at 825 litres with five seats in play. All models have an electric tailgate, too.

And if you're curious about the third row, it should be fine for anyone shorter than 175cm for shorter drives. It's not super spacious back there, and should be considered a 5+2 option. Really need a seven-seat Merc? You could get a GLS if you can afford it, or go for a V-Class luxury van. Go on. Do it!

One thing that's really neat about the new Mercedes GLE range is that the brand has decided to specify each of the models exactly the same - that makes it simple for consumers, because essentially you're just paying more for a better engine.

That means the extensive standard equipment list is the same whether you choose the 300d entry-level diesel model at $99,900 (plus on-road costs), the mid-range petrol 450 model at $111,341, or the current range-topping six-cylinder diesel 400d at $118,142.

That may seem like a pretty slim range, but you can expect Mercedes-AMG to offer two additional performance-oriented models - the GLE 53 and the GLE 63 S - in 2020. And, for context, the current BMW X5 ranges from $112,990 to $149,900, while the Porsche Cayenne lineup spans from $117,000 to $242,000.

Standard equipment includes the company's MBUX multimedia system with dual 12.3-inch screens, LED lighting with adaptive high beam headlights, 20-inch alloy wheels, a power tailgate, 360-degree parking camera, colour head-up display, the company's 'Artico' leatherette upholstery with heated front seats, DAB+ digital radio and Apple CarPlay and Android Auto.

There are multiple ways to personalise and customise your GLE, but one that's expected to attract a lot of custom is the “7 Seat Package” which adds third-row seats for people up to 180cm tall, and also incorporates electric second row seat adjustment (tilt and slide) and electric seat folding. The pack is $3900.

Other option boxes include the AMG Sport Package ($9900, comprising an AMG bodykit, panoramic roof, wireless phone charging and leather upholstery), the Night Package ($4800, adds black exterior accents), the Vision Package ($4200, including panoramic roof, wireless charging, 13-speaker Burmester sound system) and the Energising Package Plus ($6200, adding multi-contour front seats with massaging, heated armrests, air fragrances).

Our test vehicle has a 4.0-litre, twin-turbo petrol V8 engine that produces 373kW and 770Nm. That means it sits in the middle of its rivals in terms of outputs with the Mercedes being top-dog with its 450kW/850Nm combo.

Still... the SQ8 is no dainty flower when it comes to power delivery and has an impressive 0-100km/h sprint time of just 4.1 seconds. 

The SQ8 is a full-time all-wheel drive with an eight-speed auto transmission and the whole engine combo delivers a powerful but elegant on-road experience.

Powering the Mercedes-Benz GLE is a selection of engines, with petrol and diesel offered.

The entry-level power plant is the 300d, which uses a 2.0-litre four-cylinder turbo-diesel engine with 180kW of power (at 4200rpm) and 500Nm of torque (from 1600-2400rpm). It has a nine-speed automatic transmission and all-wheel drive as standard.

The range-topping diesel is a thumper. It's the 400d, which runs a 2.9-litre turbo-diesel six-cylinder with 243kW of power (at 4000rpm) and 700Nm of torque (from 1200-3000rpm). It also has a nine-speed auto and AWD standard.

The sole petrol model at launch is the 450, which employs a twin-turbocharged 3.0-litre in-line six-cylinder engine with 270kW of power (at 5500rpm) and 500Nm (at 1600-4500rpm). It uses a nine-speed automatic transmission with AWD, but this version is the only one with mild-hybrid tech, using 48-volt EQ Boost tech to help add 16kW and 250Nm for short stints of added performance (0-100km/h in just 5.7 seconds, apparently), and allowing the engine to shut off under light throttle or lift-off situations.

If you plan to tow, there's a factory-fit tow pack available that allows 750kg unbraked and 3500kg braked towing across all grades. This pack is the one from the factory - remember that - and it costs $1900. If you instead fit one as an aftermarket fit, the figures are 750kg/2700kg respectively.

The official combined (urban/extra-urban) fuel cycle figure is 11.9L/100km, which is lower than its rivals.

My real world usage sits at 12.3L/100km after a mix of open-road and urban driving.

This result is decent for a performance SUV but expect it to be thirsty in an urban environment as the on-board gauge hit the mid-20s in the city.

Based on the large 85L fuel tank theoretical driving range is 714km and around 690 using our real-world result. Respectable for a performance SUV but not as good as some family SUVs.

Fuel consumption varies between the models, as you'd expect.

The 300d is the most frugal of the mix, with an official combined cycle fuel use claim of 6.9 litres per 100 kilometres. The 400d, with its bigger six-cylinder diesel, is said to use 7.7L/100km. The 450 petrol model has the highest claimed fuel use, at 9.1L/100km, and that's despite the fact it's the only version of this trio to bring electrification into the mix with the EQ Boost 48-volt mild hybrid system.

On test at the launch of the GLE we saw a displayed return of 9.4L/100km for the 300d model, but there was a fair bit of country road and highway driving in the mix.

All versions of the GLE are fitted with an 85-litre fuel tank.

The SQ8 delivers on power because it’s effortless to get up to speed and the pick up is super responsive when the start/stop function is turned off (otherwise there can be some lag).

The engine doesn’t sound like a big and grumbly V8, though. There are some growls but it’s mainly when you turn the engine on and not to be obnoxious about it but if you're in a V8, you want to hear it as it’s part of the fun of having a big bruiser engine like this!

What doesn’t help the V8 soundscape is the fact the cabin sounds like a noise-cancelling headphone inside. There is a small hum from road noise but it’s pretty darn quiet. Almost EV quiet at times but that means the driving experience leans more towards refined and elegant rather than sporty and fun. 

The SQ8's handling is great - super direct steering, stable in corners and well-rounded passenger comfort when it comes to suspension.

You still get road feedback, which I like as a driver, but it’s not too stiff thanks to the adaptive suspension.

The SQ8 is a large car but you wouldn’t know it when it comes to parking. The 360-degree view camera is clear and the dynamic guidelines help you to position this big unit even the smallest of car parks.

The launch drive was limited to the 300d variant, though I did get a chance to sample the version with air suspension, as well as the model with the standard steel suspension.

Now, before we get too nerdy, this is an important element for a luxury SUV. Ride comfort is arguably as vital as effortless power. And, sadly for the GLE, neither model sets any benchmarks for suspension control and comfort.

The steel-sprung model doesn't have adaptive suspension at all, meaning that it can be bouncy, wobbly, unsettled and stiff all at the same time. The country road I sampled it on showed that the standard suspension offered up a quite nervous experience, never feeling as settled as a luxury SUV really ought to.

The air suspension version is definitely better, but still not as good as a BMW X5, Audi Q7 or VW Touareg. It lacks the body control and comfort that a true luxury SUV ought to offer.

Now, that might matter to you, or it might not. You might think the look of the car - with 20s, 21s or 22s filling the guards - is more important than how it deals with lumps and bumps. But it's our job to tell you how the land lies, and the GLE simply can't match the better SUVs in this segment as a driver's tool.

There is another level of suspension which the CarsGuide team (myself included) hasn't yet had the chance to sample - the E-Active Body Control system, which includes curve-tilting so it can make the car feel level through corners, and a system that'll scan the road ahead to predict bumps and lumps and prime the suspension to deal with it. That system is $13,000... and, while I haven't sampled it yet, it's my hope that it makes all the difference to the GLE.

So, what about the other driving elements? Well the steering is light and accurate, and decently responsive at low speeds or highway pace, and you're never left guessing as to what'll happen.

The engine, too, is decent - a 2.0-litre with 180kW and 500Nm is nothing to be sneezed at - but in a vehicle this large, with a kerb weight of 2165kg, and with a nine-speed automatic taking care of forward progress, it can be a busy engine.

That's because the transmission will shuffle between ratios when you encounter a hill as it doesn't quite have the grunt to simply stick in a gear and tug you along. It's not that big of a deal, and the transmission is smooth enough and pretty hard to catch out, but it is a little less effortless than a six-cylinder would no doubt be.

All in all, I was left wanting more from the drive experience. Maybe the higher-grade models with the highest-grade suspension will prove a better flag waver for the new-generation GLE.

As you'd expect, the Mercedes-Benz GLE has achieved the highest possible five-star ANCAP safety rating under the stricter 2019 criteria. Indeed, the GLE was given the best ever score for child occupant safety.

The GLE is loaded with the safety technology and equipment you would expect. There's auto emergency braking, lane departure warning, lane keeping assist (with active lane assist - it will merge into the next lane when you indicate), blind-spot monitoring, rear cross-traffic alert, front cross-traffic alert, adaptive cruise control, a 360-degree camera with reversing camera, front and rear parking sensors, semi-autonomous parking, and driver fatigue detection.

The GLE has nine airbags (dual front, front side, driver's knee, rear side, full-length curtain).

All GLE models have three top-tether restraints for child seats, and dual ISOFIX anchors in the second row. The seven-seat model has no third-row child restraints.

The SQ8 comes with a five-year/unlimited km warranty, which is a normal term for the class.

It also comes with capped servicing for five years or up to 75,000km and averages $920 per service, which is very good for the segment.

Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first.

Mercedes-Benz stands by its three-year/unlimited kilometre warranty plan, stating at the launch it has no plans to extend it to match what most of the mainstream brands now offer (five years). But it's not alone in the luxury segment in that regard.

The big point the company's local reps made was that they're trying to lower the cost of ownership for customers through servicing packages. You can pre-pay them, or you can pay as you go (PAYG).

The GLE requires maintenance every 12 months or 25,000km. The pre-pay option is $2700 for the first three years/75,000km of maintenance or, if you decide to PAYG, the costs are $850, $1200 and $1250 (totalling $3300 over the same period). It makes sense to pre-pay then, and you can bundle the cost into your finance, too, so you'll notice it less.

There is three years roadside assist included at no cost if you buy the car brand new, as it coincides with the warranty period.
