Mercedes-Benz EQ-Class vs Audi SQ5

What's the difference?

When I was telling my colleagues about the Mercedes-Benz EQC my summary was, basically, it’s the best electric luxury car I’ve driven. 

It’s plusher than a Jaguar i-Pace, more polished than a Tesla Model X - indeed, it feels like a different kind of electric car to both of those models. It’s an impressive foray into the segment, and we can’t wait for the chance to put it against some like-minded electric European luxury SUVs at some point in the future.

Let’s forget the money, for a second, because yes, you’re paying more for the Sportback variant. But if you can afford it, then why wouldn’t you. This is a sleeker, sportier and more stylish answer to the regular Q5, which was already a super-solid offering in the segment. And as far as I can tell, the practicality sacrifices you have to make are minimal at best. 

So why not?

The Mercedes-Benz EQC is entirely different to what we expect from the brand, but it’s really what we expected all along when it came to an electric SUV from the Daimler stable.

It is sleek, streamlined and smooth, with panels that almost look like they’re formed from liquid. And it has the eco-edgy graphics you’d expect, with a specific grille treatment (yes, a real grille), headlights that are unlike any other Benz (they even have an LED that runs the width of the grille), and a rear-end style that looks almost like it was penned with another Stuttgart-based brand in mind… Porsche. I’m talking about Porsche.

But one thing that I really love about the EQC is its moustache. It's more prominent when the car is finished in white paint, but there’s a moustache that former Daimler chief Dieter Zetsche himself could be envious of. And he had one helluva soup strainer.

It is clearly made to be slippery, despite essentially sharing its underpinnings with the more conventionally angular - yet still rounded-edged - GLC SUV.

While it is a nicely styled gizmo, I found there are some things that could be annoying.

For instance, I was trying to plug in at night in a dark area, and while there is a small light above the charge port, other EVs have a light that actually illuminates the area where you’re plugging in. 

And also, the plug port is on the driver’s side. If, like me, you had to charge up with the car on the street, it just adds a little bit more anxiety to the whole situation. I shudder to think what could happen if the charger was hit by a passing car - folding the mirrors in is one thing, but you can’t fold the power cable! The lead for the charger is long, thankfully. 

I know, most people (maybe even all people!) who buy and EQC are going to have undercover parking in a garage or carport, but it’s still worth remembering that the filler isn’t on the kerb side like a number of other EVs. 

It has almost identical dimensions to that car: 4774mm long on a 2873mm wheelbase, with a width of 1884mm and a height of 1622mm. For context, GLC is 4669mm long, same wheelbase, a bit wider (1890mm) and just a little more height (1639mm).

What about interior design? Well it’s also familiarly different, with a number of changes to the materials used but still the same tech and comfort you’d expect. Check out the interior images in the section below.

Our adventure began with the SQ5, and, to my eye at least, it looks mean, and more like a jacked-up hot hatch than sportier version of a mid-size SUV.

Speaking of which, it looks bigger than a mid-size, too, as though the flattened roof has pushed the rear out for more length, at least visually.

By far its best angle, though, will be afforded to the people in front of you on the road, with each peek in the rear-view mirror revealing a wide, forward-leaning grille, all black honeycomb mesh, with a cat-clawed bonnet and headlights that sweep back into the bodywork, hinting at speed before it even sets off. 

Side on, the massive 21-inch alloys hide red brake calipers, but it does also reveals a tale of two SUVs, with the front half looking taller and straighter, while the rear roofline is more raked as it flies towards a fairly small rear windscreen with a roof spoiler that juts out over it. 

At the rear, the quad exhaust tips (which sound great), and a boot spoiler moulded into the bodywork complete the package.

But even in lesser lesser Q5 45 TFSI guise, this Sportback looks the business, I reckon. Though a little more premium than performance-focused, perhaps.

As the name suggests, the Sportback version gives you, well, a sportier back, and it all starts at the B-Pillar, with a more raked roofline that gives this version of the Q5 a sleeker, more slippery look. 

But they aren’t the only changes. In Sportback models, the single-frame grille upfront is different, and the grille is also positioned lower, and seems to jut out from the bonnet more, for a lower, more aggressive look. The lights are also positioned a little higher, and those massive air vents on either side are different, too.

The cabin is the usual level of Audi niceness, with a big central screen, big digital screen in front of the steering wheel, and a sense of genuine solidity and quality wherever you look.

There are some questionable materials at work, though, like the door trims and the hard plastic that your knee rubs against when driving, but all in all, it's quite a lovely place to spend time.

If you’re thinking the EQC looks like a seven-seat SUV, you’re wrong. It’s a five-seater, with a decent sized boot, too.

The luggage capacity is 500 litres, which is decent for a car of this size, but bear in mind there is no spare wheel under the boot floor. 

Rear seat space is reasonably spacious for someone my size (182cm) sitting behind their own driving position, with decent knee and toe space. Headroom is not terrific, though, and anyone taller will need to watch their head as they get in and out of the car as the top sill eats into space quite a bit. 

Any middle-seat passengers might find the room a little less likeable, as the transmission tunnel intrudes quite a bit. Those with big feet might find shoehorning themselves in and out a bit of a challenge as the sills are quite large, and our car even had optional ($1200) “aluminium-look running boards with rubber studs” - side steps, essentially. They get in the way, too.

But if you’re just sitting two abreast in the back the seat comfort is really good, the trim quality is excellent, and there is a flip down armrest with the storage bin and pop out cupholders. There are rear air vents (no climate control adjustment in the back, though, and no USB charging either), and there are two map pockets, plus bottle holders in the doors. Up front you will find a mix of familiar elements if you’ve sat in any recent Benz model, but a few unique finishes and trim elements that might be new to you.

There’s a beautiful horizontal fin theme that runs around the cabin, as well as the now-traditionally audacious looking Burmester sound system speaker covers. They don’t quite gel with the aesthetic, to my eye. 

The dash-top material - “fine surface texture”, as Benz calls it - is unlike anything else we’ve seen from the brand, it’s kind of like a soft silky slippery fabric trim. While there are lovely copper trim elements that just add something visually entertaining and appealing to the space.

There is a large covered centre console bin with 2x USB-C charge points and there is an additional USB-C upfront next to the wireless phone charger. The Mercedes touchpad system that aligns with the MBUX media screen is reasonably easy to get used to, but being a Benz there are plenty of options for usability - the centre screen is a touch-capacitive unit, or you can use the steering wheel-mounted controller on the left side of the wheel to control the middle screen. The right thumb controller manages the driver info screen.

It was mostly very easily managed, although the menus did get stuck at times for me - mainly in the section around the energy consumption. Plus I tried the whole “Hey, Mercedes” command thing, and it failed on numerous occasions. 

The Q5 Sportback range stretches 4689mm in length, 1893mm in width, and around 1660mm in height, depending on the variant. It rides on a 2824mm wheelbase. 

And remember when I said there were few practicality penalties for the new sportier look? This is what I meant.

Up front, it's basically the same Q5, so if you know that car, you'll know this one, with its spacious and airy feeling front seats.

In the back, though, things are a little different, just not quite as different as I was expecting. The new sloping roofline has actually only reduced headroom by 16mm. I’m 175cm tall, and there was clear air between my head and the roof, and plenty of leg-room, too.

The central tunnel arrangement means you probably don’t want to squeeze three adults across the back, but two would really be no problem at all. That way, you can deploy the back seat divider to uncover two cupholders, use the two USB charge ports or adjust your climate controls, including temperature settings.

In the 45 TFSI and SQ5 models, the rear seats also slide or recline, meaning you can prioritise luggage space or passenger comfort, depending on what you're carrying.

Up front, there’s heaps of little cubby spots, including a key storage spot under the aircon controls, another in front of the gear shift, a phone slot next to the gear shift, two cupholders in the big centre console, and a surprisingly shallow centre console that’s home to a wireless phone charger and a USB port, joining the regular USB port under the drive mode selector.

And at the rear, Audi reckons there’s 500 litres of storage, only about 10 litres less than the regular Q5,  which grows to 1470 litres with the second-row folded.  

The three-model line-up (two regular Q5s and the SQ5) Sportback range kicks off with the Q5 40 Sportback TDI quattro, which will set you back $77,700 (which is plenty more than the $69,900 of the regular Q5).

The entry-level Q5 Sportback gets 20-inch alloys, a standard S Line sporty exterior styling treatment, LED headlights and tail lights, and an electric tailgate with gesture control. Inside, there’s leather trim, electric sport seats, three-zone climate, paddle-shifters for the steering wheel and ambient interior lighting.

You also get the virtual cockpit, the 10.1-inch central screen with all the Connect Plus services, like live traffic, weather and restaurant tips, as well Android Auto and wireless Apple CarPlay.

The range then steps up to the Q5 45 Sportback TFSI quattro, yours for $86,300. That's another marked jump from its regular Q5 equivalent.

That model delivers a new 20-inch alloy wheel design, a panoramic sunroof, and Matrix LED headlights, The S Line treatment extends to the interior, along with Nappa leather trim, heated front seats and a sliding or reclining rear bench. You get a better sound system, too, with 10 speakers, including a sub-woofer. 

Finally, the SQ5 Sportback is yours for $110,900 (up from $106,500), and delivers 21-inch alloys, adaptive dampers and red brake callipers, while inside you get electric steering adjustments, a head-up display, colour ambient lighting and a banging Bang and Olufsen stereo with 19 speakers.

The EQC has a power output of 300kW and it has 760Nm of torque, which is enough to see its claimed 0-100km/h acceleration pegged at just 5.1 seconds.

The EQC’s top speed is 180km/h (limited for the sake of the batteries), and it has an 80kWh lithium-ion battery pack.

It uses a pair of asynchronous motors - one front, one rear - and they can alternate to do what’s best in the situation - be it working in 2WD (RWD or FWD), or in AWD. 

If you’re thinking about an EQC as a towing option, the towing capacity is 750kg for an un-braked trailer and 1800kg for a braked trailer.

There are three engines total here, kicking off with the 2.0-litre TDI in the Q5 Sportback 40. It produces 150kW and 400Nm - enough for a sprint to 100km/h in 7.6s. The 2.0-litre TFSI in the Q5 Sportback 45 petrol bumps those figures to 183kW and 370Nm, lowering your spring to 6.3s. 

Both pair with a seven-speed S tiptronic automatic, and feature a 12-volt mild-hybrid system to smooth out acceleration and lower fuel use, as well Quattro ultra, which can disconnect the rear drive shaft so only the front wheels are driven.

The SQ5 gets a seriously lusty 3.0-litre TDI V6 which deliver 251kW and 700Nm, and a sprint of 5.1s It also gets a 48-volt mild-hybrid system, and an eight-speed tiptronic transmission.

With an 80kWh battery pack and a Type 2 CCS plug (up to AC 7.4kW / DC 110kW) the charge times vary pretty greatly depending on what output you’re powering up from.

Mercedes-Benz says a DC fast charging station should be able to replenish the battery bank in 1 hour 22 minutes (at a maximum of 110kW, though some Chargefox stations offer charge rates up to 350kW) while an AC charging station (like you’d find in car parks) or Mercedes-Benz’s own Wallbox system should take about 12 hours 13 minutes.

Charging from a regular household powerpoint is a last resort option. It is claimed to take 46 hours 40 minutes from empty to full (230-volt outlet, 10-amp/2.3kW). I plugged in to a powerpoint in my house and the car’s info display was stating it would take 9.5 hours to achieve the remaining 16 per cent of charge. It didn’t get to 100 per cent before I had to unplug, however.

My not-so-urban test drive loop commenced with 97 per cent of battery charge and an indicated range of 363km available. The idea was to get a feel for the “range vs reality” of the situation, so I did it in Comfort drive mode with the climate control active and no intent to either thrash the vehicle or baby it to save battery.

My drive ended with 36 per cent indicated charge remaining, after I’d covered 231.6km. That means, based on the car’s own algorithm, that it would have covered 315km before the battery was depleted, which is a long way short of the claimed 434km range.

The indicated energy consumption was 20.8kWh/100km, which is ‘thirsty’ for an EV. On our recent electric car comparison test, the most efficient of our EVs - the Hyundai Ioniq Electric - used just 13.0kWh/100km. Yes, I know the EQC is a lot heavier (2425kg kerb weight), but even the Tesla Model 3 was notably more efficient (18.5kWh/100km) than the EQC over very similar terrain and driving.

However, our testing saw us return an even better consumption rate than Mercedes-Benz’s claimed figure, which is 21.4kWh/100km.

All Q5 Sportback models are fitted with a 70-litre fuel tank, which should produce a driving range in excess of 1000kms - though prepare for pain at the pump. Sometimes premium fuel in Sydney can run to around $1,90 a litre, for example, so the good stuff will cost you around $130 bucks a tank in the petrol cars.

Audi says the Q5 Sportback 40 TDI will sip 5.4 litres per 100km on the combined cycle, while emitting 142g/km of c02. The 45 TFSI needs 8.0 litres per 100km on the combined cycle, and will emit 183g/km of c02. The SQ5 sits somewhere in the middle, with 7.1 litres per 100km and 186g/km of c02.

If you have a garage and a Wallbox connector, there’s no reason the Mercedes EQC couldn’t be a terrific option as a commuter, a second car, or even your primary vehicle. 

The thing with all electric cars is that it’s about settling into a rhythm. If you use the car to commute to work, maybe you can charge it there. Or you might have a solar array and charge at home.

No matter the situation, you’ll be getting a rather nice vehicle to live with, based on my week with the EQC.

It’s a plush car, that’s for sure. The silence it offers is truly relaxing, and there’s effortless torque to pull you away from a standstill. The way you can build pace to overtake, the rush of noise-free acceleration, is pretty astounding. Perhaps not as visceral as in a GLC 63 AMG, but it’s still an experience.

The steering is direct and doesn’t require much thought, though it does lack a little bit of feel. But it’s easy to predict and quick to respond, making for pleasant progress around town. It’s easy to park, as well, with a great surround view camera system, as well as front and rear parking sensors. And if you’re not confident, the car has semi-autonomous parking, too.

The brake pedal feel takes some acclimation, because it responds pretty well, but the action is hard to modulate at times. That is partly due to the brake regeneration system, which actively captures energy that would have otherwise been lost during braking. You can adjust the level of aggression of the regen brakes, too, by tapping either the up or down shift paddles. The most aggressive setting will almost pull you up to a halt from urban speed without any brake pressure required.

The suspension of the EQC feels more settled than the last GLC I drove, and that could be in part due to the extra weight and stiffness of the battery cell under the body. The centre of gravity feels low, and it feels stuck down to the road in most situations.

The ride is mostly fine, but with big 20-inch wheels and low profile tyres, it can jar on hard edges. I also noticed that it can feel a bit unsettled at higher speed, as the body moves around - from side to side - more than I would have expected. It deals well with undulation changes and big dips, and if the surface is good, so are the comfort levels in the cabin. 

How to best describe the drive experience in the Q5 Sportback? That's easy. And it's 'easy'.

Honestly, I know this is ostensibly the sportier version of the Q5, but the truth is that, in the 45 TFSI version we tested, it's a comfortable, light-feeling drive experience that only ever reveals its sporty nature when you really command it to.

Left in its Auto drive mode, the Q5 45 TFSI will positively waft around town, road noise kept to an absolute minimum, and feeling somehow smaller and lighter than its dimension would suggest.

You can dial-up the aggression by cycling through the drive modes, of course, but even in Dynamic guise it never feels too harsh, too aggressive. More that you've simply tightened the screws a little bit.

Plant your right foot and the 45 TFSI will collect speed in a way that Audi refers to as "hot hatch-like", punching towards the 100km/h sprint with verve and aggression. But having just stepped out of the SQ5, it still feels somehow sedate, and almost relaxing, rather than out-and-out aggressive.

And that's because the SQ5 variant is clearly, purposefully, the performance-focused variant here. I think this V6 engine is an absolute peach, and its the kind of powerplant that inspires you to stick with the vehicle's most dynamic settings, putting up with the just-too-firm suspension settings so you can access more fo the grunt more quickly.

And it feels constantly ready for action. Tap the accelerator and the car bristles, dropping down a gear, revving higher and preparing for your next command.

Through bends, it feels smaller and lighter than you might expect, with plenty of grip and steering that, while not overflowing with feedback, feels true and direct.

Short answer? It's the one I'd take. But you'll pay for it.

The Audi Q5 Sportback carries a five-star ANCAP safety rating thanks to the regular Q5, but that’s really the minimum cost of entry these days. So what else do you get?

Advanced driver-assist systems on offer here include autonomous emergency braking (with pedestrian detection), active lane-keep assist with lane change warning, driver attention assist, blind-spot monitoring, rear cross-traffic alert, park assist, a great surround-view camera, parking sensors, exit warning and tyre pressure monitoring, and more radars than you can poke a stick at. 

There's also twin ISOFIX anchor points, and top-tether points for child seats.

It mightn’t have the same method of propulsion as a petrol or diesel Merc, but it has similar service requirements. You still need to take it to the workshop for maintenance every 12 months - or every 25,000km! - whichever comes first.

Owners can either pay as they go for servicing, or pay up front and bundle it into their finance. The upfront rate is $1350 for three years/75,000km. Pay as you go will peg you along at $450 (year one), $750 (year two), $450 (year three). 

When the EQC launched it came with a three-year/unlimited kilometre warranty plan, but that was recently updated to a five-year/unlimited km plan, bringing Benz inline with the likes of Korean luxury maker Genesis, not to mention the majority of mainstream car brands.

All Audis are covered by a three-year, unlimited-kilometre warranty, which really isn’t great in a world of five-, seven- and even 10-year warranties.

The brand will let you prepay your services, required annually, for the first five years, with the regular Q5 Sportback billed at $3140 and the SQ5 billed at $3170.
