Audi S7 vs Mercedes-Benz GLE300

What's the difference?

Audi’s S7 Sportback wraps style, comfort and sportiness in an appealing package that is sure to please onlookers and occupants alike.

The great engine/transmission aside, the S7 Sportback also has cutting-edge technology at a more affordable pricetag, though less-than-comfortable rear-seat space lets it down a little.

We wish the car we sampled didn’t have the all-wheel steering, as we much preferred the more neutral feel of the S6 sedan we also drove but, overall, the S7 Sportback puts forward a strong case for its existence.

Whether you like Coupe SUVs or not is an entirely subjective matter, but there’s no denying the GLE 53 is a tech and spec showcase – some of the best Mercedes has to offer. If you can get past its relatively enormous dimensions and naturally compromised visibility – it’s even a hoot to drive.

The significant proportion of GLE consumers who are picking one of these over the regular version will be pleased with its many improvements. We’ll know more about how its price and specification lines up against primary rivals closer to its Australian launch date, so stay tuned.

Audi’s second-generation A7 has always been a bit of a looker, but Audi has taken it up another notch in the S7 Sportback.

Differentiating the S7 Sportback is a more aggressive bodykit, complete with larger air intakes up front, blacked out exterior trim, quad-exhaust tips (denoting that it’s an Audi Sport model) and large 21-inch wheels

The S7 doesn’t go too overboard with the aggressive appointments however (that’s what the top-spec RS7 Sportback, due here later this year, is for), but balances its sportiness with a stately aesthetic.

We think the S7 Sportback is stunning, especially the white exterior colour that gives it an almost Stormtrooper-like look, but even our test car, finished in Daytona Grey, while much more subtle, is still easy on the eyes.

We especially like the strong shoulder line, chiselled doors and sloping roofline of the Sportback body style that combine in profile to make the S7 look like a sprinter on the starting blocks ready to pounce.

Inside, the S7 Sportback scores all of Audi’s latest interior technology, including a 12.3-inch Virtual Cockpit instrumentation and dual-screen centre console layout.

The triple screen set-up definitely helps the S7 Sportback feel very cutting-edge from the driver’s seat, especially when you start to play around with the multimedia system that sports haptic feedback when you press the screen.

Everything is laid out in a clear, concise and easy-to-use manner, while the surfaces of the dashboard are covered in soft-touch, premium materials.

If we’re being honest, we'd probably skip the red-leather interior of our test car in favour of something a little more subdued, but to each their own.

We like the integrated air-vents that blend well into the dash, while the sea of black is broken up with some aluminium detailing and different finishes.

The GLE Coupe has improved so much in its looks it’s easy to see when it came to the second-generation GLE underpinnings, Benz had it planned from the beginning.

It looks mean, especially the 53 with its giant toothy grille. The stance is low and wide for an SUV, and I’m especially a fan of the much more resolved rear end.

It’s less bulbous and frumpy, more slick and menacing, rounded out nicely by the flick of a lip spoiler jutting out the rear.

You might think proportionally, the very idea of a coupe SUV is silly, and there’s no denying that, but then, you and I might not be the target audience.

That audience is someone looking for an avant-garde take on what a sports car actually looks like. They will be pleased – I’d say its even more resolved than BMW’s X Coupes and a little less science-fiction than Audi’s Q8. The incoming Coupe version of the Porsche Cayenne will be a real challenger.

The presence the GLE Coupe exudes extends to the inside, where there’s plenty of Mercedes wow factor. Level what you might at the brand’s use of silver fittings and flat dual-screen set-up, there’s no denying Benz offers an interior entirely unlike its competition.

The GLE has one of the best of the recent Benz interiors, too. I love the way the big dual-screen set-up is framed in a 'leather'-clad bay of vents.

I also like the real wood trim on our test car which runs across the dash and flows into the doors, and of course the wholly unnecessary vent-overload (becoming a Benz signature) pride of place in the centre of the dash.

It’s complemented by the tape-deck style silver switches for the climate controls which protrudes underneath.

The materials are great, with Artico trim running down the centre console, and across each doorcard. Almost every surface you’ll reasonably come into contact with is soft, and the commitment to real metals and wood is admirable.

Other highlights include the comfortable seats (with heating which extends into the armrests!) and AMG wheel which is flashy and aggressive, well suited to such a gratuitous vehicle.

Measuring 4969mm long, 1908mm wide, 1417mm tall and with a 2928mm wheeblase, the S7 Sportback falls well and truly into the large car class.

Up front, the driver and passenger have plenty of room, while the seats and steering wheel are almost infinitely adjustable to find the perfect position.

As you can imagine though, the sloping roofline does eat into the rear-seat headroom a little.

The outboard seats offer plenty of leg- and shoulder-room, but the slanted roof prevents my six-foot-tall frame from sitting up straight comfortably.

Don’t get me wrong, the space is perfectly useable for children or even some smaller adults, but don’t expect to get any basketball players in those seats.

As for the middle seat, only children will find it comfortable due to the protruding transmission tunnel and higher-set seat.

The S7 Sportback’s boot offers at least 535 litres of space and expands to 1380L with the 40:20:40 split-fold rear seats stowed.

Being a liftback (or Sportback in Audi parlance) means the boot is much more practical than a standard sedan, and with such a large aperture, bigger items such as suitcases or golf clubs won’t be annoying to load and unload.

Bag hooks, storage tie-down points and carbo netting also feature to ensure your goods don’t roll around when the S7 Sportback is in motion.

Storage around the cabin though, could be a little better as the wireless smartphone charger takes up a fair chunk of room in the shallow central storage bin under the front armrest.

The usual storage tray found ahead of the shifter is also absent, due to the dual-screen centre console layout, but two generous cupholders and sizeable door pockets are still available up front.

Second-row passengers get access to a fold-down armrest with shallow storage tray and cupholders, as well as door pockets that can accommodate large bottles.

Naturally, the entire idea of shaving a solid bit of roof off of an SUV is going to compromise the amount of ‘practicality’ you get from such a large footprint.

Those compromises are not only there, but they are quite obvious. The sheer height of the GLE makes peering over the edge of the bonnet difficult for parking, and the sloped roofline causes the A-pillar to eat quite a bit of your field of vision.

As you might imagine, it’s genuinely difficult to see much out of the back of the GLE Coupe. I caught myself continually adjusting the rear vision mirror – as though somehow it would grant me more vision out of the letterbox rear window.

While front passengers get away with plenty of room, rear passengers are a little harder done by. This is again, largely due to the roof pillar, which eats into headroom and gives the cabin a claustrophobic feel.

Thankfully, legroom is fantastic (largely due to that massive GLE platform), the trim is all just as good as it is in the front seats, and the back of the centre console gets its own set of climate controls, adjustable air vents and USB-C power outlets.

I’d hardly say there’s an abundance of bottle holders for occupants, but there are a few. They aren’t big or packaged in ideal locations, but you’ll be able to get away with four 300ml containers in the front and four in the rear.

The boot has been re-worked from the GLE Coupe’s predecessor, there’s five extra litres on tap, for a total of 655 litres (VDA) – so it’s far from useless, but still down significantly from the full size GLE which has a massive 825L of space.

Benz has made the boot more useful, too, lowering the sill by 60mm for easier access.

There’s no dancing around the fact that the GLE Coupe is a niche, gratuitous product, targeted at a well-off consumer.

We don’t know what the pricing will be for the Australian range yet – and we won’t for a few months. But what we do know is Mercedes-Benz will only bring two highly specified variants to our market for the launch.

Those two will be the AMG-tuned GLE 53 which we were able to test at the launch, and a slightly lesser specified GLE 450.

Expect tall pricing, north of the wagon bodied GLE 450 ($111,341) for the 450 Coupe and outgoing GLE 43 Coupe ($145,829) for the GLE 53 Coupe.

The GLE Coupe will go into battle against the new BMW X6 (from $121,900) and Porsche Cayenne (from $116,600) and Audi Q8 ($128,900)

Standard features, as with the rest of the second-generation GLE range will be pretty good. We don’t know exactly what Australian-specified vehicles will get, but the GLE 53 as tested in Europe came with an extensive list of items.

You can expect all variants to get 20- to 22-inch alloys, electric tailgates, LED headlights, and Benz’ signature ‘Artico’ faux leather interior trim. The 53 also had a swish fully RGB adjustable interior ambient lighting suite and real wood in the dash. Very nice.

All GLE Coupes will have the impressive MBUX (I’m told it’s said “em bee you ex”, not “em bucks”) digital dash and multimedia suite, consisting of two 12.3-inch screens, one a digital dash, the other a multimedia screen.

The flashy setup also supports Apple CarPlay and Android auto as well as the usual connectivity via Bluetooth and packs several USB C outlets alongside Aux and USB 2.0. Our test 53 had a head-up display, too.

Mercedes’ built-in assistant (summoned by uttering 'Hey Mercedes') has perhaps the best native voice recognition on the market in terms of its accuracy and what it can do.

You can do things like adjust air conditioning, open the sunroof shade (oh yes, the GLE comes with a panoramic sunroof, too), and even find your specific music tracks via internet radio.

Then there’s the built in nav suite which is also one of the better ones on the market, featuring some very cool innovations.

The system will switch to the forward-facing camera when approaching an intersection and show you where to exit using augmented reality. Neat.

The 53’s system is also uniquely adjustable with AMG-specific themes and modes for the dash cluster, setting it apart from the lesser GLE 450 when it arrives.

It’s safe to assume there will be an extensive options list, including the 'E-Active Body Control' system (a $13,000 option on the wagon version) which uses cameras to detect road quality and optimize the air suspension system to suit. It also leans into corners. We’re keen to test it when it becomes available on the GLE 450.

Powering the new S7 Sportback is a 2.9-litre twin-turbocharged petrol V6, punching out 331kW/600Nm, which is paired to an eight-speed automatic transmission that sends drive to the road via Audi’s quattro all-wheel-drive system.

The result is a zero-to-100km/h acceleration time of 4.6 seconds.

Keen-eyed Audi fans might note that those are the exact same engine and outputs as the RS5 Sportback, RS5 Coupe and RS4 Avant, and they’d be right, however, Audi has added the 48-volt mild-hybrid and an electric powered compressor (EPC) to reduce turbo lag in the S7 Sportback.

It’s a similar system first employed in the SQ7 large SUV, and basically means that the EPC is spooling up the turbo at low engine speeds for better off-the-line performance.

The mild-hybrid technology no doubt helps shift the S7 Sportback’s 2040kg weight with peak power now available earlier on in the rev range (from 5700rpm), while maximum torque is available from 1900rpm.

Compared to the older car, the new S7 Sportback matches its predecessor in power, but ups torque by 50Nm despite losing the old car’s 4.0-litre twin-turbo V8 engine.

Australia will only get one engine in the GLE Coupe – a 3.0-litre 48-volt mild-hybrid in-line six-cylinder twin-turbo petrol.

There will be two states of tune. The 450 will be able to make use of 270kW/500Nm, while the AMG-spec GLE 53 we were able to drive at the launch has more power still (thanks to extra hybrid augmentation on the turbo) for a total of 320kW/520Nm.

For a quick comparison, the single-variant Q8 produces 250kW/500Nm from a twin-turbo V6, while the equivalent X6 – the M40i packs a 3.0-litre twin-turbo in-line six to make 250kW/450Nm.

The GLE 53 has a nine-speed auto transmission which is specially tuned by AMG to go with the expanded list of available drive modes. All Australian GLE Coupes will be all-wheel drive via a permanently active '4Matic+' system.

Official fuel economy figures for the S7 Sportback are 8.5 litres per 100km, but in our brief time with the car we managed 13.6L/100km, mainly due to the inner-city and country B-road driving.

The 48-volt mild-hybrid system works to reduce fuel usage, by as much as 0.4L/100km according to Audi, and allows the car to coast with the engine off between speeds of 55km/h and 160km/h for up to 40 seconds.

The start/stop system also aids in reducing fuel usage.

The claimed combined cycle fuel consumption figure for the GLE 53 Coupe is 9.3L/100km, and while that’s not bad for something this heavy – keep in mind it’s an NEDC figure and not the widely-used WLTP figure so it could be a bit different by the time the GLE Coupe launches here.

Regardless, the fuel consumption is helped along by the abundance of ratios in the transmission and 48-volt mild-hybrid additions which help to remove inefficiencies from the drivetrain.

Our sweet but brief drive route in the Austrian Alps was not a fair reflection of fuel consumption, so we don’t have a real-world figure for you yet.

Expect the GLE 53 to require premium 98 RON unleaded petrol to fill its 65-litre fuel tank.

Audi’s formula for a go-fast vehicle has always been simple – quattro all-wheel-drive for grip, potent engine for speed – and the new S7 Sportback remains true to that formula.

We are big fans of the 2.9-lite twin-turbo V6 engine, which is matched wonderfully with a smooth-shifting eight-speed automatic transmission.

The S7 Sportback always seems to have plenty to give no matter where you are in the rev range, and the transmission isn’t bogged down with slow gear changes up or down.

Though it’s hard to tell how much the EPC helps in getting the S7 up to speed, if you have you window down and accelerate hard from a standstill, you can hear the electronics whirring away.

The standard air suspension also does a wonderful job at absorbing road imperfections in comfort, while it can be switched over to dynamic for a more sporting characteristic.

Grip is plentiful thanks to 255/35 tyres and the quattro all-wheel-drive system but, as with other Audis, the S7 Sportback tends towards understeer when pushed hard around a corner.

Being such a long and wide model, you definitely feel the S7 Sportback’s size on the road, especially when navigating through quick direction changes, but this is where the $7700 Dynamic Package comes into play.

It adds a sports differential, variable ratio steering and all-wheel steering, all aimed at sharpening the S7 up in the bends.

Our test car was fitted with the option pack, but it left us a little cold.

The all-wheel steering especially, made the S7 Sportback’s handling feel too artificial for our tastes, and we were never able to gauge where the rear end wanted to go in a corner.

If we were buying one, we’d leave the Dynamic Package option box unticked.

Bringing the S7 Sportback to a stop are big 400/350mm brake rotors front/rear, with six-piston callipers in the front.

Ceramic brakes with grey-painted callipers can be optioned for $18,000, but the standard stoppers do a fine job scrubbing speed in the S7 Sportback.

The resurgence of the in-line six engine is a glorious thing, and it makes the GLE 53 quite a fun, if chunky, unit to drive.

Acceleration is urgent thanks to the pre-spooled first-stage turbo, and the transmission flicks through the gears like there’s nothing to it.

It’s perhaps not as 'smart' on the downshifts as competitor transmissions from Audi or Porsche, although Mercedes was keen to point out this will get better over time as the car’s computer 'learns' your driving characteristics.

Thankfully though, unless you’re in 'Eco' mode, the GLE 53 does a great job of letting you ride each gear out, giving you that signature in-line six sensation of an entire revolution range of relatively even torque distribution – a characteristic which Mercedes has gone to pains to perfect on a turbocharged engine.

This has the result of letting you bask in the sound for precious extra seconds.

While not as furious as preceding V8s – it is distinct. It’s refined and rich, although more subdued than you might have come to expect from vehicles wearing the Affalterbach badge.

I’m a fan. It’s an engine befitting a more refined sports machine than a garish statement.

The AMG suspension tune was great, too, keeping the massive Coupe truly under control in the corners, while soaking up bumps (which we’ll admit, there were few of on Austria’s immaculate roads).

It was interesting to read colleague Matt Campbell found the standard suspension less than impressive on the regular SUV-shaped variants, so we’ll see what the more basic set-up on the 450 is like at the Coupe’s launch.

I have no complaints about the steering, which proved to be responsive, smooth and accurate, while not erring too far on the heavy side, even in 'Sport' or 'Sport+' mode.

My main complaints lie with outward visibility and the sheer size of the GLE’s body. There were some nerve-wracking moments piloting it at speed around narrow streets with tall snow embankments encroaching.

And no matter how much I adjusted my seat and mirrors, the view out the back was particularly compromised.

We don’t know exactly how Australian cars will be specified yet, but expect the two GLE Coupes to come with flagship active features like high-speed auto emergency braking (AEB), lane departure warning with lane keep assist, blind spot monitoring, rear and front cross traffic alert, adaptive cruise control, 360 degree parking sensors and cameras, fully auto LED headlights, semi-autonomous parking, and driver attention alert.

The GLE has nine airbags and dual ISOFIX child seat mounting points in the outer rear seats.

Regular wagon bodied GLE class vehicles have maximum five-star ANCAP safety ratings as of 2019, and we’ll update you when we hear more about the Coupe variants.

Like all new Audi models, the S7 Sportback comes with a three-year/unlimited kilometre warranty with three years roadside assist.

Audi’s warranty still lags behind Mercedes-Benz and Genesis, two premium marques that offer a five-year/unlimited kilometre warranty on their models.

Scheduled service intervals are every 15,000km/12 months, whichever comes first.

A three- or five-year service plan is available for the S7 Sportback, priced at $2350 and $4110 respectively.

Mercedes continues with its three-year/unlimited kilometre warranty which is frustratingly standard across European premium car manufacturers in Australia– particularly its primary competitors, Audi and BMW. We doubt this will change any time soon.

Like VW Group competitors, though, Mercedes is now bundling in service costs in packages which can be tacked on to finance. The GLE requires servicing once a year or every 15,000km – we’ll update you on the cost of the packages closer to the Coupe’s local launch.
