Audi Q5 vs Mercedes-Benz GLA-Class

What's the difference?

It might be a late return to the PHEV game for Audi, but it’s an impressive one. Everything great about the Q5 remains - dynamically engaging, responsive powertrain - but you get the added benefit of electric power.

This could be the car to prove that plug-in hybrid medium SUVs don’t have to be bland family transport. If the Q5 is anything to go by, going green can be downright fun!

With Mercedes-Benz’s vast number of SUVs, there is room for an urban luxury crossover niche, and the GLA delivers in spades.

Indeed, in 250 4Matic guise, it is that rare thing – a high-riding hatch with dynamics to shame most dedicated pocket-rockets. It really is a hoot if you find the right road, regardless of weather conditions. The Benz has towering talent.

However, even without desirable options like adaptive dampers and a full suite of driver-assist safety technology, the GLA is expensive, does not quite carry off the price tag from an interior quality point of view, and struggles to maintain the degree of comfort and refinement expected from a Mercedes – with or without the $3K necessary to score adaptive dampers.

Still, especially because of the way the GLA looks, goes, stops and steers, if you can afford it, you’ll be rewarded. There’s never been a more rounded GLA.

The second-generation Q5 has been around for six years, and it was very much an evolution of the original, but it still looks attractive in the metal. You couldn’t call it edgy, but it is handsome.

Both PHEV body styles get the S line exterior package as standard, which adds a unique honeycomb grille, S line bumpers front and rear, Audi Sport wheels and it borrows the rear spoiler from the SQ5.

While many will favour the swoopy Sportback body style, I think the Q5 is at its most arresting in SUV body style, bathed in the gorgeous 'District Green Metallic' paint. Stunning.

Inside, only the Sportback gains the S line interior, which includes a leather three-spoke steering wheel with multifunction, shift paddles and hands-on detection, Nappa leather upholstery with contrast stitching, and aluminium inlays. The SUV seats are leather-appointed. 

It’s fair to say Audi’s interiors have modernised since the launch of this Q5 in 2017, but it’s still hard to fault. The multimedia screen jutting out the top of the dash is a little old school these days, but the materials and quality are top notch.

Looking like a mini-me GLC, today's GLA trades some of its predecessor’s edgier design elements like the slammed roof and exaggerated broad-shouldered stance for a more amorphous if elegant appearance. Even with the cliché plastic cladding around the squared-off wheel arches, it’s still a looker.

The net result is arguably the most attractive of all the MFA2 A-Class offshoots. It sits well within the Mercedes hierarchy of SUVs, bringing a swoopy coupe-like silhouette compared to the ultra-upright GLB.

Along with being 30mm wider, it’s also visibly taller than before, with a handy 213mm of ground clearance compared to just 157mm last time around. And the wheelbase has been stretched to the benefit of rear-passenger room – a bugbear of the old GLA. That's progress.

As - predominantly - a family hauler, the Q5 has always done well in the practicality stakes. And adding a plug-in hybrid powertrain hasn’t changed that. Although you do lose some boot space compared with the petrol models - but more on that in a bit.

Up front, the Q5 has plenty of nooks and storage slots in the console, including a longer shallow slot to hold phones. The central bin is deep enough and the door bins can swallow big bottles and more. Housing the phone charger on the top of another storage spot in the console works as it can be hidden by the larger storage lid for security.

As the Q5 is older than some of Audi’s fresher models, there are physical buttons for things like air conditioning, seat heaters, and controls for drive modes and other vehicle functions.

It might not look as schmick as having a screen to house everything, but from a practicality and safety perspective, it’s welcome.

This approach also extends to the multimedia system which is fairly simple to navigate with a logical menu. Audi’s system gets a tick, as does the digital cockpit - something the brand pioneered.

While the leather appointed seats in the SUV are nice, the quilted Nappa leather seats in the Sportback are much more luxurious. And the ‘Rotor Grey’ colour scheme is simply beautiful. They offer more than enough support in the front row and they are comfy without being super plush.

There’s ample leg and headroom in the front row.

That is the same for the second row. So much headroom even with a panoramic sunroof. And behind my 183cm (six foot) driving position, there was room to spare in front of my knees. It’s such a good size.

Also, the rear seats have some bucketing so passengers will feel a little spoiled. There’s also knee-level air vents, map pockets, two USBs and a 12-volt port, a fold-down armrest with cupholders and ISOFIX points on the outboard seats.

The rear row folds 60/40 and there’s decent room in the boot, which has a power operated tailgate. 

Given some of the PHEV hardware sits directly under the boot floor, it’s little surprise that the SUV version (465 litres) loses 55L of space compared with the petrol-powered 45 TFSI.

Similarly, the Sportback (455L) drops by 45L. Also, despite the swoopy roofline, the Sportback only loses 10L of cargo space compared with the more practical looking SUV.

Those PHEV bits also mean there is no spare wheel - only a tyre repair kit.

Compared to before, the 2021 GLA is some 122mm taller, so ushers in a higher hip point for loftier seating – reducing that jumped-up hatch feel. Headroom improves obviously, as does rear legroom, a corollary of a 30mm wheelbase stretch (to 2729mm).

Wide apertures also make entry into and out of the German-built GLA child's play, though the solid heft of their doors is serious business at this end of the segment, very satisfyingly Teutonic and totally on-brand. This is something you won’t enjoy in a Subaru XV.

Then you s-c-r-a-p-e the underside of the front doors on the pavement literally every time you swing it to get out, and wonder whether Mercedes engineers have ever been to Australia. This fail drove us spare. Heaven help the GLAs in towns and cities with bluestone sidewalks. Maybe all that extra AMG packaging is the culprit.

Still, most of the other basics are spot-on and can’t really be faulted; cosy yet spacious for four adults – especially up front, ample vision, an excellent driving position aided by heaps of seat and steering wheel adjustability, cosseting front sports buckets that you just sink into, torrents of ventilation from those delectable turbine vents and stacks of storage. Collectively they make the GLA a welcoming, opulent place to travel in. Only the hapless fifth occupant squished between the outboard rear-seat passengers might think otherwise. But nobody buys this Benz for carting people around. That's the GLB's job.

Several years ago, Daimler poached a senior Audi designer and since then Mercedes’ dashboards have morphed into a multi-coloured multimedia diorama of touchscreen technology that threatens to completely take over the universe. Choose the right combination of colours and lighting and it's like your very own White Night on wheels. Starting with 2018’s A-Class, the striking, spangly MBUX system that underpins all this has come to be widely admired and imitated. For aesthetics anyway, with its vivid hues, panoramic displays and simple, tiled applications, it’s been a real trip.

Anyway, back to reality. From a tactility and functionality point of view, there’s still work to be done.

Access to the multimedia (including our GLA's banging optional audio system) and car settings areas is possible via a mildly fiddly finger-pad arrangement down forward in the centre console, or smaller yet much more annoying thumb sensor tabs on the wheel spokes. These are not easy to modulate on the move. Additionally, their menus can be confusing to navigate through and sometimes counterintuitive in operation. Mercedes obviously realises this as a quick-guide pamphlet is provided on old-fashioned cardboard paper. How quaint.

Eventually all areas can be mastered over time, but the functionality is complicated and may overwhelm the not-so-tech savvy. Additionally, the ‘Hey, Mercedes!’ voice control is impressive for getting MBUX to perform basic multimedia and vehicle settings-related changes, but it too-often erratic, unreliable and ultimately frustrating for more complicated commands. Perhaps elocution lessons on behalf of the operator may help.

But not as much as the profound disappointment we endure from the cheapness of some of the materials, the wincing cellophane-like sounds when pressing on some of the surfaces such as the door cards, or that emanate after a particularly bumpy section of bad roads. Sheeny reflections and hard textures in a car optioned with extras that total up to nearly $82,500 just don’t cut it.  

At least in this latest-gen GLA, the rear seat area seems much improved over the previous models, with more space, comfy and supportive seating (remember ours featured the $607 sliding function that ought to be standard) and a reclining backrest. All amenities are present, with deep pockets, fresh air from twin vent outlets, reading lights and thoughtfully placed armrests – but, again, the latter’s extendable cupholders feel brittle and cheap.

Further back, the 435-litre cargo area is sufficiently sized and practical for smaller family use (at last), aided by a 40/20/40 backrest fold and that slide-able cushion to extend capacity further. There is no spare wheel, but a tyre inflation kit is fitted in lieu.

Overall, then, better than before, with that fundamental rock-solid heft, luxurious aura and alluring premium-car aroma. The dazzling MBUX screen-related visuals, too, are endlessly entertaining to explore when the vehicle is not moving, but the GLA’s cabin is still not quite up to Mercedes’ reputation for exacting over-engineered excellence.

Or even to the standards of some mainstream alternatives.

The latest GLA’s evolved dimensions is presumably to put some space between it and its GLB 5+2-seater SUV fraternal twin, giving Mercedes-Benz blanket SUV market coverage. From GL (for Geländewagen, or off-road vehicle) A, B, C, E and S (as well as the G-wagen icon that started it all back in '79), there’s a premium option for everybody… if not every budget.  

In the GLA’s case, the entry-level 200 front-driver starts from $55,100 (before on-road costs); moving up to the $66,500 250 4Matic, and then to two performance powerhouses – the AMG 35 4Matic and supernaturally fast AMG 45 S 4Matic+ flagship, from $82,935 and $107,035 respectively.

Even the base GLA 200 includes new and improved autonomous emergency braking (AEB) among other safety-related technologies, as well as the brand’s glamorous MBUX multimedia system with wireless Apple CarPlay/Android Auto, digital radio, satellite navigation, reverse camera, climate control, wireless phone charging, powered tailgate, automatic parking, auto high beam, rain-sensing wipers and 19-inch alloys.

All the extra techy stuff doesn’t come for free though – prices jump almost $10,000 over the less-powerful previous-generation GLA 180 that the 200 replaces – though we expect the former badge to return in time.

In contrast, the GLA 250 4Matic is ‘only’ $3500 more expensive than its predecessor, gaining a terrific 2.0-litre four-cylinder turbo instead of a Renault-Nissan-sourced 1.3-litre turbo, all-wheel drive (with an Off-Road Engineering Package that gives the car some very light off-road capability), and other niceties such as heated electric front seats with memory function, a panoramic sunroof, more direct steering and lowered suspension (for a sportier drive).

Note that adaptive cruise control costs extra – a curious oversight at this price point. It’s part of a $1531 optional Driving Assistance Package, which also includes Active Lane Change Assist, extended semi-autonomous driver assistance in traffic jams (meaning full stop/go capability) and route-based speed adaptation. Do it.

Our test car had it, along with a $915 Vision Package (includes fancier adaptive headlights and a 360-degree camera), $1915 Sports Package (with AMG styling upgrades inside and out, perforated disc brakes, privacy glass, shift paddles and lowered ‘Comfort Suspension’), a Night Package (less brightwork, more black finishes) and sports direct-steering with corresponding wheel), $1531 20-inch AMG Black alloys, a $1915 Communications Package with upgraded audio and head-up display among a litany of other gear, $2838 AMG Exclusive Package with adaptive dampers, cooled as well as heated front seats, an ‘Energising Comfort’ ambience-enhancing 'experience' and special leather upholstery, $1531 Patagonia Red metallic paint and $607 rear-seat fore/aft adjustment. Total cost after the added luxury car tax: $82,446. Gulp.

Not cheap in anybody’s language. Nor, for that matter, are the GLA’s rivals, which owe their existence to the original’s spectacular sales trajectory and the trail that this blazed last decade.

Lexus’ loaded UX 250h hybrid AWD and Audi Q3 Sportback 40TFSI quattro slip slightly below the standard GLA 250 for both pricing and power, while the BMW X2 M35i and its Mini Countryman JCW cousin, along with Jaguar’s E-Pace E250, also offer in-the-same ballpark pricing but quite a bit more space as well as pace.

It’s also worth noting that Volvo’s XC40 T5 AWD conspicuously undercuts all from just $57,000, though now we’re talking about putting square pegs into round holes. Speaking of which…

The Q5 pairs a 2.0-litre four-cylinder turbo-petrol engine - found in many VW Group products - with a plug-in hybrid set-up that includes a lithium-ion battery pack and an electric motor.

The total system output is 270kW of power and 500Nm of torque, which is impressive. In fact, it has more power - but a little less torque - than the SQ5 performance flagship. 

It drives all four wheels thanks to Audi’s quattro all-wheel drive system, and does that via a seven-speed dual-clutch automatic.

Mounted transversely, Mercedes’ M260 1991cc 2.0-litre four-cylinder petrol engine features a twin-cam, 16-valve design, a twin-scroll turbocharger and variable-valve timing, to help deliver 165kW of power at 5500rpm and 350Nm of torque at a low 1800rpm. With an impressive 97.2kW per tonne, it can hit 100km/h in 6.7 seconds, on the way to a 240km/h top speed.

All four wheels are driven by an eight-speed dual-clutch transmission (DCT), though most of the torque at lower speeds or during reduced throttle loads is delivered to the front wheels until extra traction is required out back. The gearbox is one of the very best of its type we’ve experienced – seamless, strong and largely lag-free.

The PHEV’s battery capacity is 17.9kWh and that ensures the Q5 has an electric driving range of up to 55 kilometres on the WLTP protocol. 

Audi says the average daily commute of an Australian is 35km, so technically many people could get to work and back using electric power only.

It might not sound like a huge amount, but it’s more than the 41km offered by the BMW X3, although it doesn’t come near the Lexus NX’s 87km claim.

Energy consumption is rated at 23.9kWh/100km, and the official fuel consumption figure for the Q5 is 2.0 litres per 100km - bettering the X3’s 3.2L/100km figure but not as frugal as the Lexus (1.3L).

It has a 54-litre fuel tank and emits 45 grams per kilometre of CO2.

The Q5 PHEV has a Type 2 plug and comes with a charger to add more juice at home.

It has an AC charging capacity of 7.2kW and it will take two and a half hours to fully charge using a home wallbox charger. You can also plug it into a regular wall socket at home and it’ll be charged up in about eight hours, or overnight. It's not capable of DC charging.

Weighing in at 1668kg (kerb), and with a bluff nose and high ground clearance also not helping, we didn’t expect great fuel economy, particularly given how hard and fast the GLA 250’s performance bandwidth is. It’s tempting to just blast your way from point A to point B.

However, at the pump we averaged 9.8 litres per 100km, which isn’t too bad at all considering the available muscle. The official figure is 7.5L/100km, for a carbon dioxide emissions rating of 170 grams per kilometre. With a 51-litre fuel tank, the theoretical range is around 680km.

Note that the GLA 250 requires 95 RON premium unleaded petrol as a minimum.

The Q5 has always been the driver’s pick among its peers - specifically the BMW X3 and Mercedes-Benz GLC. You could argue a Porsche Macan is more engaging and you’d probably be right. But of those immediate German rivals, the Q5 takes the cake.

Adding a PHEV powertrain and the circa-300kg of extra weight that brings should impact dynamics - but somehow, it doesn’t. 

First of all, the Q5 PHEV can do the 0-100km/h dash in just 5.3 seconds which is hot hatch territory. 

But the really impressive thing about this Q5 is how well it handles, despite that extra weight. The battery pack is housed under the boot floor, and Audi engineers have done a bang up job in ensuring it retains that dynamic prowess it's known for. 

We drove on some delightfully twisty roads in the Gold Coast hinterland for this launch event, and the Q5 didn’t miss a beat.

It maintained composure when pushed into tight corners, and had plenty of grip. And the electric urge coming out of those corners - providing you have battery charge left - only helps the experience.

Typically sharp Audi steering is indeed present and welcome.

Riding on 20-inch Audi Sport alloy wheels, and with a sporty bent, you’d think the ride quality would be impacted. But that was another pleasant surprise.

The Q5 soaks up corrugations with the standard suspension set-up, and the tyres have a decent sidewall. So no unpleasant sharp bumps detected.

The cabin is reasonably well insulated from most outside intrusion as well.

A soaring 2.0-litre turbo engine application, this is a slick, stirring and robust performer that can also do efficiency as effortlessly as launch the GLA 250 4Matic towards the horizon. Let’s not mince our words. This is a fast and fiery mover.

Three drive modes – Eco, Comfort and Sport – provide a wide spectrum of acceleration and throttle responses, and all deliver precisely what you’d expect. Eco’s fine for pottering around town smoothly and serenely; Sport morphs into a searing and seamless speed demon; and the default Comfort sits somewhere in the middle as the best of both worlds. There really is no faulting Mercedes’ M260 masterpiece.

The DCT also happens to be one of the better dual clutch autos, avoiding the lag and clunkiness pitfalls usually associated with this sort of gearbox. It’s even comparatively smooth off the line on hills. Ours came with the optional handy set of manual-mode paddle shifters, adding a welcome level of interactivity autos tend to overlook. Too bad Mercedes persists with that fiddly column lever that is forever prone to knocking the car out of drive. Even after 15 years, it's still so annoying.

What all this means for the urban driver is strong acceleration for flitting in and out of traffic gaps, as well as incredibly instantaneous point-to-point responses for commanding manoeuvrability, thanks to ultra-eager steering and assisted by outstanding brakes.

With struts up front and a multi-link rear end as standard, the GLA 250’s chassis, too, is a transformative for what is essentially a high-riding hatchback – but only if your pockets are deep enough.

Fitted with that near-$3K AMG Exclusive Package that includes adaptive dampers, our Benz displayed a definite hot-hatch attitude that really would make it the darling of Golf GTI owners who’ve outgrown their rides but not their girl/boyracer desires. Superb handling and hunkered-down roadholding really do make this the driver’s premium compact crossover. You can pretty much point and shoot this Merc as you might a Golf R, and likewise in most weather conditions thanks to all that reassuring tenacious grip.

Plus, if you’re put off by the hard ride in Sport, the Individual mode allows the driver to engage the soft damper mode while the engine and steering retain the hardcore settings. It’s a win-win situation – as long as you can stretch to that AMG Exclusive pack. We strongly recommend it, given the balance between ultimate high-speed control and comfort.

However, while this is all good news for rural and country folk seeking hot crossover fun, back around town, poor urban road conditions can reveal a flaw in the chassis’ ability to properly smother bumps and ruts. It’s the small frequency stuff that seems to transmit through, never really settling down.

The result is a jittery ride, that may somewhat undermine the GLA’s upmarket sheen. There’s also a fair degree of road noise coming through. Perhaps sticking with the 19-inch alloys instead of those lovely 20-inch rims is the solution here.

Mercedes-Benz is a long and proud pioneer in passenger-vehicle safety, and the GLA is no exception… except that for the full suite of safety assistance you need to fork out more in the GLA 250.

The standard roll-call of advanced driving assist systems includes nine airbags (front, pelvis side and window bags for driver and front passenger, side airbags for rear occupants and a knee airbag for the driver), AEB with pedestrian and cyclist detection, and blind-spot monitoring with an exit warning that alerts the driver of approaching cyclists or vehicles if the door begins to open into their path.

The AEB system has a working range of between 7km/h and 200km/h.

Active Lane Keep Assist, an active bonnet that raises to reduce head injury, Cross Wind Assist, Pre-Safe accident anticipatory systems and traffic sign recognition tech are also present.

Additionally, front and second-row seatbelt reminders are fitted, as well as two rear-seat sited ISOFIX child-seat anchorage points and a trio of child-seat tether points behind the backrest.

But you’ll need to fork out another $1531 for the optional Driving Assistance Package, which includes adaptive cruise control with full-stop/go, Active Lane Change Assist, extended semi-autonomous driver assistance in traffic jams, and route-based speed adaptation.

At the time of publishing, the H247-series GLA’s crash test rating results had not been published, but the closely-related GLB tested in 2020 managed a full five stars.

The Q5 comes with Audi’s five-year/unlimited kilometre warranty. This was an increase on its previous term that Audi announced at the start of 2022. The PHEV is also covered by an eight-year/160,00km battery warranty.

Service intervals are every 12 months or 15,000km, whichever comes first, and Audi offers a capped-price service plan for five years that costs about $3500 all up. That’s a little pricer than BMW and Volvo’s plan.

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $550 for the first year, $750 for the second year and $1250 for the third year, totalling $2550. Alternatively, buyers can also choose a Service Plan, starting at $2050 for the first three years (saving $500 from the normal capped-price service plan), $2950 for four years and $3500 for five years.
