Mercedes-Benz E-Class vs Audi SQ2

What's the difference?

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

The Q2 is good value and great to drive – especially the SQ2. The exterior looks new, but the cabin feels older than the larger Q3, and most other Audi models.

More standard advanced safety tech would make the Q2 even more appealing, as would a five-year, unlimited-kilometre warranty. While we’re at it, a hybrid variant would make enormous sense. 

So, a great car, but Audi could offer more to make it an even better proposition for buyers. 

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

This updated Q2 looks almost identical to the previous one and really the only changes are subtle styling tweaks to the front and back of the car.

The front air vents (they aren’t real air vents on the Q2, but they are on the SQ2) are now larger and pointier and the top of the grille is lower. Around the back, the bumper now has a similar design to the front, with those pointy polygons set wide apart.

It’s an angular little SUV, full of sharp-edged shapes like some kind of acoustical wall in an auditorium.

The SQ2 just looks more aggro, with its metallic-trimmed air vents and beefy quad exhaust. 

The new colour is called Apple Green and it’s not really like any colour on the road – well not since 1951, anyway when this hue was hugely popular on everything from cars to telephones. It’s also very close to Disney’s “Go Away” green – look it up and then ask yourself if you should be driving a car that’s kind of invisible to the human eye.

I digress. Other colours in the range include Brilliant Black, Turbo Blue, Glacier White, Floret Silver, Tango Red, Manhattan Grey and Navarra Blue.

Inside, the cabins are the same as before, apart from the larger, sleeker media display, and there are some new trim materials, too. The 35 TFSI has silver inlays with a diamond paint finish, while the 40TFSI has aluminium door sills.

The Q2 has beautiful quilted Nappa leather upholstery, which goes beyond just covering the seats and to the centre console, doors and armrests.

All options offer well laid out and premium feeling cabins, but the disappointing part is that it's an older Audi design, which started out in the third-generation A3, launched in 2013, and still exists on the Q2, even though most Audi models, including the Q3, have the new interior design. This would bug me if I was thinking about buying a Q2. 

Have you thought about a Q3? It’s not that much more in price, and it’s a tad bigger, obviously. 

The Q2 is tiny, at 4208mm end to end, 1794mm wide and 1537mm tall. The SQ2 is longer at 4216mm long, 1802mm wide and 1524mm tall.  

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

The Q2 is basically a current model Audi A3, but more practical. I’ve lived with the A3 Sedan and Sportback and while rear legroom is just as confined in those as it is in the Q2 (I’m 191cm and need to squish my knees behind my driving position) getting in and out is easier in the SUV, with its elevated ride height and taller door apertures.

The easier access helps enormously when helping kids into their child seats. In an A3 I need to kneel on the footpath to be at the right level to put my son into the car, but not with the Q2.

The boot space of the Q2 is 405 litres (VDA) for the front-wheel-drive 35 TFSI and for the SQ2 it’s 355 litres. That not bad, and the large hatch makes for a big opening, which is more practical than a sedan’s boot.

Inside, the cabin isn’t enormous, but rear headroom is good, thanks to the fairly high roof.

Cabin storage isn’t terrific, although the front door pockets are big and there are two cupholders up front.

Only the SQ2 has USB ports in the back for rear passengers, but all Q2s have two USB ports up front for charging and media – plus all have wireless charging for phones.

The Q2 entry grade is the 35 TFSI and it lists for $42,900, while the 40 TFSI quattro S line is $49,900. The SQ2 is the king of the range and lists at $64,400.

The SQ2 has never been to Australia before, and we’ll get to its standard features in a moment.

Aussies have been able to buy a 35 TFSI or 40 TFSI since the Q2 arrived in 2017, but now both have been updated with new styling and features. The good news is the prices have only gone up by a few hundred bucks,  compared to the old Q2.

Standard on the 35 TFSI are LED headlights and taillights, LED DRLs, leather seats and steering wheel, dual-zone climate control, Apple CarPlay and Android Auto, eight-speaker stereo with digital radio, front and rear parking sensors and a rear-view camera.

That was all standard on the previous 35 TFSI, but here’s what’s new: an 8.3-inch media screen (the old one was seven inches); a proximity key with push button start (great news); wireless phone charging (brilliant), heated exterior mirrors (more helpful than you’d think), ambient interior lighting (aww… pretty); and 18-inch alloys (heck yes).

The 40 TFSI quattro S line adds sports front seats, drive-mode selection, a power tailgate, and paddle shifters. The previous one had all that, too, but this new one has the sporty S line exterior body kit (the previous car was just called Sport not S line).

Now, the 45 TFSI quattro S line may appear  not to get much more than the 35 TFSI, but the extra money is getting you more grunt and an awesome all-wheel-drive system –  the 35 TFSI is front-wheel-drive only. If you love driving and can’t afford the SQ2, then $7K extra for the 45 TFSI is absolutely worth it.

If you have saved all your pennies and the SQ2 is what you’re zeroing in on, then here’s what you get: Metallic/pearl effect paint, 19-inch alloys, matrix LED headlights with dynamic indicators, the S body kit with quad exhaust, sports suspension, Nappa leather upholstery, heated front seats, 10-colour ambient lighting, stainless-steel pedals, auto parking, a fully digital instrument cluster, and a 14-speaker Bang & Olufsen stereo.

Of course, you get an incredible high-output four-cylinder engine, too, but we’ll get to that in a moment.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

There are three grades and each has a different engine. 

The 35 TFSI has a new 1.5-litre four-cylinder turbo-petrol engine making 110kW and 250Nm; the 40 TFSI has a 2.0-litre turbo-petrol four making 140kW and 320 Nm; and the SQ2 has a 2.0-litre turbo-petrol as well, but it puts out a very impressive 221kW and 400Nm.

The 35 TFSI is front-wheel drive, while the 45 TFSI quattro S line and SQ2 are both all-wheel drive.

All have a seven-speed dual clutch automatic transmission – nope you can’t get a manual. There are also no diesel engines in the line-up.

I drove all three cars and, from an engine perspective, it’s like turning the ‘Smile Dial’ up from Mona Lisa in the 35 TFSI, to Jim Carrey in the SQ2, with Chrissy Teigen in between.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

Audi engines are superbly modern and efficient – even its monster V10 can shut down cylinders to save fuel, and so can the new 1.5-litre four-cylinder engine in the 35 TFSI. Audi says that over a combination of urban and open roads, the 35 TFSI should use 5.2L/100km.

The 40 TFSI is thirstier at 7L/100km, but the SQ2 demands a bit more at 7.7L/100km. Still, not bad. 

What’s not good is the lack of a hybrid, PHEV or EV variant of the Q2. I mean the car is small and ideal for the city, and therefore a perfect candidate for an electric version. Not having a hybrid or EV is why the Q2 model range doesn’t score well for its overall fuel economy.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

When it comes to the driving part, Audi can almost do no wrong – everything the company makes, whether it’s low powered or rip-your-face-off fast, has all the ingredients for engaging driving.

The Q2 range is no different. The entry-grade 35 TFSI has the least grunt and, with its front wheels pulling the car along, it’s the only one in the family that’s not blessed with all-wheel drive, but unless you’re doing laps at a track you’re not going to be wanting more power. 

I drove the 35 TFSI for more than 100km on the launch, through the country and into the city, and in all situations, from overtaking on highways to merging and slow traffic, the most affordable Q2 performed well. That 1.5-litre engine is responsive enough and the dual-clutch transmission changes swiftly and smoothly. 

Superb steering and good visibility (although that rear three-quarter view is slightly obstructed by the back pillar) makes the 35 TFSI easy to drive.

The 45 TFSI is a good mid-point between the 35 TFSI and the SQ2 and comes with a very noticeable bump in oomph, while the extra traction from the all-wheel drive is a reassuring addition. 

The SQ2 isn’t the hardcore beast you might think it is – this thing would be super easy to live with daily. Yes, it has firm sports suspension, but it’s not overly hard, and that engine, which nudges almost 300 horsepower, doesn’t feel like a Rottweiler on the end of a leash. If anything, it’s a Blue Heeler that loves to run and run, but is happy to take it easy and get fat.  

The SQ2 is my pick of the bunch, and not just because it’s quick, agile, and has an intimidating growl. It’s also comfortable and luxurious, with sumptuous leather seats.  

The Q2 was given the maximum five-star ANCAP rating when it was tested in 2016, but by 2021 standards it is light on advanced safety tech.

Yes, AEB with pedestrian and cyclist detection is standard on all Q2s and the SQ2, and so is blind-spot warning, but there’s no rear cross traffic alert or reverse AEB, while lane-keeping assistance is only standard on the SQ2, along with adaptive cruise control.

For a car that will most likely be purchased by younger people, it doesn’t seem right that they’re not being protected as well they would be in more expensive Audi models.

For child seats, there are two ISOFIX points and three top-tether anchor mounts.

A space-saver spare is under the boot floor.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.

The pressure for Audi to move to a five-year warranty must be hugely intense, with Mercedes-Benz offering one, along with pretty much every other mainstream brand. But for now, Audi will only cover the Q2 for three years/unlimited kilometres.

As for servicing, Audi offers a five-year plan for the Q2 costing $2280 and covering every 12-month/15000km service over that time. For the SQ2, the cost is only a fraction higher at $2540.
