Audi Q5 vs Mercedes-Benz E300

What's the difference?

The new Q5 does a lot right even if it doesn’t feel as resolved from behind the wheel as I had expected.

It catapults one of the oldest premium SUV nameplates into this decade, and all three of its launch powertrain options are great, so you can’t really go wrong.

Each features the smoothness and efficiency of genuine hybrids backed by punchy turbo combustion thrills, while the increase in standard kit across the entire range is notable at a very reasonable price increase.

The E-Class is stacked with kit, looks great, and is an effective and comfortable way to get around in built-up areas or across the countryside.

While it’s not the most dynamically engaging - it’s pipped by its Bavarian rival there - it offers more comfort-oriented features than most, and the cabin is a pleasant place to spend a day driving.

If you're disposed towards stumping up the asking price, the extra outlay for the 'Plus Package' will probably be most relevant to you if you’re covering long distances due to the Airmatic suspension.

Otherwise, even a simple-spec E300 provides a step up from what you might expect from an executive sedan.

Proportionally, the new Q5 is quite a departure from its curvaceous predecessors, thanks to a more chiseled bodyline and stronger flares over its wheelarches. While this makes it the biggest stylistic departure for the Q5 ever, embracing its all-new PPC (Premium Platform Combustion) underpinnings, its stylistic motifs are still somehow very familiar.

The traditional Audi grille is maintained, although has been modernised with a geometric pattern and integrated highlight pieces depending on styling package, and even the light profiles manage to be somewhat familiar despite their twinkly new customisable LED elements and contemporary slimline appearance.

A closer look only makes the car feel more contemporary, with strong contours around its face and bumpers, which were absent from its more plain-looking predecessors.

In addition, the brand tells us the Australian market in particular has one of the highest levels of uptake of large wheels, so it offers a range of designs to choose from on the options list, many of which are on the larger side, despite the standard wheel being 19 inches.

The interior is where the biggest changes are. While Audi interiors have been familiar for the longest time, the new Q5’s interior appointments feel dropped directly out of its Q6 e-tron electric alternative.

The result is a completely re-thought approach to the interior design, which is now dominated by huge touchscreens as well as a collection of contemporary shapes and mouldings that transport the Q5 into the current decade.

Still, elements of familiarity are present. The seats feel like Audi seats, the materials are as you’d expect for the brand and the wheel is backed by familiar switchgear.

Evolution rather than revolution is obvious when it comes to the E-Class’ styling, but that’s in Mercedes’ best interests, because it’s still a good-looking thing, and being a bit subtle is warranted in the executive sedan game.

The biggest changes come in the headlights and tail-lights. Up-front there are now more than one million pixels in the LED headlights, which have adaptive high beam as standard and are more connected to the grille via black trim, as has been seen in EQ electric models.

Underneath, the bumper now features an AMG-style 'A-wing' apron as part of the 'AMG Line' exterior package as standard. A set of 20-inch AMG alloys are also included.

To the rear, and the digital tail-lights feature a Mercedes-Benz star motif, making its lighting signature now more recognisable from behind.

The German Rainbow is well-represented with mostly shades of grey, black, or white available, though 'Verde Silver Metallic' is a slightly retro green, and 'Nautic Blue Metallic' is a subtle and classy tone.

The daring ‘Manufaktur’ shade of 'Patagonia Red Metallic' is a $2500 option, as is 'Opalite White Bright' while 'Alpine Grey Solid' is $2900.

While the interior might feel as modern as they come, it also brings with it some of the pitfalls of contemporary design themes.

The most obvious is the over-reliance on touch panels for controls. The most egregious example is the lack of physical buttons for the climate control, which is interacted with via a permanent part of the touchscreen, but it doesn’t end there.

On top of this, there are capacitive gloss finish panels for the steering wheel controls, and even a capacitive panel in the door to control the mirrors and lights. It all looks swish, but isn’t the best to use compared to just… buttons.

Apple CarPlay worked flawlessly in my time with various versions of the car, and the stock software is fast and crisp. Interestingly the digital instrument cluster is the most plain version of Audi’s usually stellar virtual instruments yet. Without the big animated cluster dials it used to have it feels a bit less fun to look at.

Adjustability and space is great for front passengers, as is the amount of visibility on offer, plus the seats are as comfortable as ever in all grades.

Storage is ample in the cabin, with big bottle holders in the centre console, large pockets in each door, and a halfway decent centre console. The phone charger sits tucked away at the front with the USB-C outlets and a volume dial.

The back seat is less impressive. The Q5 never had the most spacious second row in this mid-sized segment, but it’s disappointing to see this new-generation car hardly improves on the formula. It’s spacious enough for me at 182cm tall behind my own driving position, with enough room for my knees and airspace for my head, but it’s certainly not as spacious as many rivals. In addition, the centre position is compromised by a huge rise in the floor, making it a hard pitch for an adult to sit there.

On the plus side, there’s plenty of amenities with bottle holders in each door, a further two in the drop-down armrest, netted pockets on the backs of the front seats, and an entire third rear climate zone with touch panel temperature control and physical air vents. There’s also two USB-C outlets.

One trade-off for the small second row is a large boot. It measures 520 litres with five seats up, or 1473L with the second row down. It also comes with a few neat things like a net and sliding cover.

Unfortunately, while there’s a small amount of underfloor storage, there’s no spare wheel, with Audi only offering a tyre repair kit.

Inside, the E-Class should feel familiar to anyone who’s spent time in a recent Benz, though the Superscreen might be the main point of difference. It’s an immediately comfortable place, though, with a relatively visually busy cabin.

The seats and their adjustability mean most drivers and passengers, regardless of height and size, should feel supported (and ideally relaxed), while touch-points are mostly either leather upholstery or digital screens.

The steering wheel, also seen in plenty of other Mercedes models, is a bit of a let-down, however, with its haptic touch pads on a slightly busy two-tier layout. This millennial found it irritating, surely too will the usually older E-Class buyer.

There are a few other small annoyances, one being that the MBUX Assistant sometimes won’t hear a command, or that not everything seems to be able to be controlled by it. The climate control vent positions are electrically adjustable to certain pre-sets through the menu, but the MBUX Assistant isn’t able to do this for you.

And while the driver display and central multimedia screen are fairly user-friendly, it’s not always immediately apparent what the quickest way to find some information or a setting is.

Our test car was fitted with the 'Plus Package', which means four-zone climate control available to the rear seats, which my 180cm-tall self found spacious with plenty of headroom, kneeroom, and even a fair bit of room under the driver’s seat.

Behind the rear seats, there’s a generous 540 litres of boot space, exactly the same capacity as the previous generation E-Class.

While cross-shopping the E-Class and a BMW 5 Series would normally be relatively easy, the Merc’s $131,500 starting price, before on-road costs, puts it plenty north of the base 520i, the only petrol one available, at $114,900. The electric i5 eDrive40 starts from $155,900, more than $20K over the Mercedes.

But the E-Class is stacked with features as standard, and while there are a couple of option packs, Mercedes Australia has tried to streamline the most popular features and specifications into the E300.

Its $131,500 price gets you a tech-heavy sedan with Merc’s latest 'MBUX' system housed in a visually impressive, if perhaps unnecessary, 'Superscreen' dash.

The dual-screen set-up incorporates a main 14.4-inch central multimedia touchscreen and a 12.3-inch display for the passenger, allowing the driver to keep, for example, a map visible while a passenger sorts out media or comfort settings.

The system is also designed to avoid taking users through sub-menus, though can be bypassed by wireless Android Auto or Apple CarPlay.

It also features a selfie camera mounted to the dash, which is disabled for the Australian market at present. Mercedes-Benz Australia hopes to change this soon.

Mercedes also plans to allow the MBUX system to learn what settings and functions will be most useful to the driver under certain conditions, but currently users are able to manually create so-called ‘Routines’ such as setting the climate control and seats to warm up if it’s below a certain temperature, and can even adjust the ambient lighting to a warmer colour.

More automation comes in the brand’s MBUX ‘Hey Mercedes’ system, which can now respond to commands without the driver needing to say “Hey Mercedes”. 

Heated and vented front seats, leather upholstery, wireless phone charging, and a 17-speaker Burmester sound system with Dolby Atmos 4D sound are also standard - the latter being a clever feature that positions different elements of the audio, usually music, to give a 360-degree feeling, as well as turning bassier tones into a physical vibration via “tactile transducers” in each front seat’s backrest. Good for bassline junkies, then (apologies to Mr. Rascal).

With the $9400 'Plus Package', the E-Class also comes with 'Airmatic' suspension and rear-axle steering (which I’ll touch more on later), power-closing doors, 'Urban Guard' to monitor your vehicle while it’s parked, an illuminated grille up front, a more capable version of the MBUX 'Interior Assistant', four-zone climate control and Mercedes’ 'Digital Light' function, which uses the more-than one-million pixels in the headlights to project onto the road or surface in front of you when turning the car off or in driving situations to alert road users of potential danger.

A $6200 'Energising Package' adds multicontour front seats with comfort headrests, upgraded climate controls with 'Air-Balance' and fragrances, upgraded seat heating with armrest heating for the front occupants and heated seats for the rear.

Here’s where things get interesting. Despite featuring three carryover engine options, the Q5’s big upgrade is the introduction of a hybrid system.

The brand calls this technology MHEV+, which I think is underselling what the system can actually do. Normally a mild hybrid (MHEV) system consists of higher-voltage electrics to assist auxiliary systems and take a small amount of load off the engine, or provide a more robust stop/start system, but this new Audi tech consists of an 18kW/230Nm electric motor placed after the seven-speed transmission that can motivate the entire vehicle under electric power for small periods. It can recapture up to 25kW of energy and is supported by a 1.7kWh battery pack.

The three engine options supported by this include the base TFSI 2.0-litre four-cylinder turbo front-wheel drive (150kW/340Nm), the mid-spec TDI 2.0-litre four-cylinder turbo diesel (150kW/400Nm) exclusively in all-wheel drive, or the SQ5’s 3.0-litre turbo-petrol V6 (270kW/550Nm).

There’s no disappointments here. All powertrains feel up to the task, and for those of you waiting for an all-wheel drive base petrol or a plug-in hybrid, the brand assures us both are on the way soon.

This lone E-Class variant is powered by a turbocharged 2.0-litre engine pumping out 190kW and 400Nm, assisted by a 48-volt battery system. Under EQ boost, an extra 17kW and 205Nm is available for a short time.

It’s hooked up to a nine-speed auto that drives the rear wheels, and it’s all pretty traditional… for 2024, that is.

Mercedes says the E300 is able to hit 100km/h in a respectable 6.3 seconds.

All engine options are also relatively efficient, although the total fuel reduction from the introduction of this new MHEV+ hybrid technology is surprisingly small. Audi says it saves up to 0.74L/100km and 17g/100km of C02, which doesn’t sound like a lot for a system that can pull the whole car.

Regardless, fuel consumption is 5.7L/100km for the TFSI 2.0L FWD petrol, 5.4L/100km for the TDI 2.0L AWD diesel, or 7.6L/100km for the 3.0-litre petrol V6 SQ5. The emissions are also relatively low for a premium SUV.

Mercedes claims the E-Class drinks 7.2L/100km on the combined cycle, and though we weren’t able to test that properly at the pump on the launch program, the trip computer showed up to 9.4L/100km after some quite spirited driving, which gradually averaged out to about 8.6L/100km in the afternoon once some more calm, E-Class-appropriate distance had been covered.

With its 50L fuel tank, the E-Class should theoretically be able to cover 694km on a single tank if the 7.2L/100km is achieved, though realistically it would be much less, 550-600km depending on driving style.

To drive the Q5 is familiar in some ways and less familiar in others. The initial impression is good, with each variant being relatively quiet on the road, offering a nice adjustability and driving position, with great visibility around the car.

The new powertrain options are all a joy to pilot, with all feeling punchy and smooth-shifting through the seven-speed auto. This smoothness is helped along by the introduction of the new MHEV+ tech, which can push the car along at reasonable speeds without needing the engine to assist.

It might not be quite as punchy as some other hybrid systems in terms of overall assist, but it’s certainly better than other systems we’ve seen on the market that barely help with driving or smoothness, and end up being a cynical emissions-saving device. It’s nice to see this tech is a step forward for the brand.

The familiar Q5 driving points are mostly intact, too, with the most notable upgrade being the ride comfort. This car is much more adept at dealing with road imperfections than its predecessor, with a softer suspension response.

This having been said, I expected more from this ground-up new platform. Each version of this Q5 I sampled felt less dynamically engaging than its predecessor. The usually sharp Audi steering tune feels a bit disconnected in this new car, with a little bit too much electrical and software assist, and the suspension, while more comfortable, isn’t as engaging in the corners.

It, too, lends the car a disconnected feeling over undulations and corrugations, giving the new Q5 an overall less resolved feeling from behind the wheel than I would have liked. The previous car was a bit sharp, but at least it was consistent in the way it responded to the road.

The previous car started to feel old towards the end of its run. Previous Audi owners will enjoy how this new car catapults the nameplate into this decade in terms of its cabin ambiance and general demeanour, it would have just been nice to see the consistency return, too.

While the E-Class has taken fairly sizeable steps in terms of its tech, it remains a fairly traditional car from behind the wheel, save for a few small changes like its mild-hybrid system and rear-wheel steering.

It’s still a petrol-powered rear-drive sedan, and it feels built more for eating up highway kilometres than it does tackling twisty turns. But that’s okay, because it will still do the latter.

Comfort is the main focus, clearly, for the E300, and the big Merc does it well. We weren’t offered a car without Airmatic air suspension on the launch, but the E-Class doesn’t seem like it would be particularly rough without it.

With it, however, large bumps and minor road annoyances only make their way into the cabin in the sense that you’re aware of them, but not bothered by them.

That slight dulling of feedback does extend to the steering wheel however, where, despite the rear-wheel steering making the car more nimble, the feedback to the driver is less encouraging of eager driving. 

While 190kW on paper doesn’t seem like enough, the E-Class makes do with its meagre engine quite well - and even though it can seem like it’s working a bit too hard at times, the E-Class’ natural state isn’t responding to a planted foot, so it’s unlikely to be a daily bother.

Engine noise, as well as wind and road noise are suitably dulled by the E300’s NVH fitout, too.

The tuning of its drive modes, in particular Comfort and Sport, seemed well-judged on our drive loop, with the option to set the 'Individual' mode to a custom configuration, most elements in Comfort while the drivetrain is set to Sport is particularly helpful when on gentle, high-speed country roads.

If you do start to approach the limits of the big sedan’s capability, it’ll let you know fairly early on. The heavy E-Class isn’t prone to sudden lurching or poor handling, and isn’t much phased by mid-corner bumps.

It’s not as dynamically engaging as some rivals, particularly the 5 Series, but it does appear to be a better provider of cross-country comfort.

ANCAP hasn’t had a go at crash-testing the E-Class yet, and it might not given the relatively small number that will be sold here compared to volume models, but Mercedes’ track record with safety is pretty stellar, and it’s extremely rare for a Mercedes to not cop the maximum five stars.

In the new E300 there are 11 airbags - plenty for a sedan. Mercedes lists front airbags, knee bags and pelvic/thorax airbags for the driver and front passenger, side bags for the rear and a front centre airbag.

It also comes with a fairly extensive suite of safety tech, including the usual ABS, lane-keep assist, blind spot monitoring and surround-view parking cameras.

But on top of that, there’s also ‘Evasive Steering Assist’, semi-automated cruise control with sign recognition, distance assist for following leading vehicles and can even project light arrows onto the road if leaving your lane, when 'Digital Lights' are optioned.

The E-Class also has a function if an imminent collision is detected in which it can, depending on the type of collision, take occupant protection measures. In the case of a side-on collision, the E-Class can “move an affected front occupant towards the centre of the car” before impact.

Audi continues to offer its fairly standard five-year and unlimited kilometre warranty with five years of roadside assist and this is paired with the option of a five-year service plan.

This costs an additional $3520 ($704 per year) for the 2.0-litre variants, or $3560 ($712 per year) for the 3.0-litre V6-powered SQ5. Servicing is required every 1500km or 12 months.

The E-Class comes with Mercedes’ fairly industry standard five-year, unlimited kilometre warranty, though Mercedes-Benz Australia was unable to confirm exact servicing pricing on the launch. 

It does however list pricing for the E-Class on its website for a three-service pack at $3325, four at $4535, and five at $6800, the latter averaging out to $1360 each.

This could increase with the new generation car, and Mercedes doesn’t list estimated serving pricing for new E-Classes yet in its booking system (I checked with one of the test cars).

Servicing intervals are every 12 months or 25,000km, whichever comes first.
