Mercedes-Benz Eqa350 vs Lexus RX300

What's the difference?

On one hand, the EQA 350 4Matic has the styling, interior presentation, forceful performance and handling prowess to make you forgive its very expensive price tag, especially when so many rival EVs are also so talented.

But there’s too much that’s ordinary about this Mercedes to justify its huge ask, including a lack of that final polish in the way it drives and rides.

Despite being a recent release, the EQA is already feeling beyond its age. For the money, the 350 4Matic feels out of its depth.

The Lexus RX300 is luxurious but affordable, making it great value and superbly comfortable, with a high level of fit and finish. Fear not about the four-cylinder engine being small – it makes plenty of grunt and handles daily duties perfectly well.

Which would you go for: An entry level Lexus RX300 or a top-of-the-range Mazda CX-9? Tell us what you think in the comments below.

A high-riding hatchback (its handy 209mm ground clearance is only 4.0mm shy of the GLA equivalent), the smooth and handsome EQA is like an EQC that’s been left in a tumble dryer for too long, shrinking into its smaller proportions.

Along with the EQA's obvious electric powertrain inclusion, differences compared to the GLA include a blanked-out grille, a redesigned bumper, fresh wheel styles and a full-width LED tail-light treatment. 

All add some character to the rather amorphous donor car.

I've mentioned the Spindle grille and its jewellery-like appeal, and even the sharp edges of this SUV make the RX300 look like a carved gemstone, but I'm not the biggest fan of this vehicle's proportions. I think the door-to-window ratio is a bit off. There's just too much door for my liking.

That said, I'm intrigued by the craftmanship, the attention to detail and the use of materials, which make this SUV both pretty and intriguing.

The cabin mixes the plushness of cushioned surfaces on the dash and the armrests  with pleasing design elements, like the swooping aluminium trim, which zig-zags its way from the instrument cluster to the passenger's side of the centre console.

The giant media display is impressive, but the functionality is awkward, to say the least, but more on that in the practicality section below.

The Luxury is the entry grade into the RX model and so comes with smaller wheels than the F Sport and Sports Luxury above it, but it does score roof rails, dual chrome exhausts, a roof-top spoiler and rear privacy glass.

How big is the RX300 Luxury? The dimensions show it to be 4890mm long, 1895mm wide and 1690mm tall.

How do the looks compare with rivals such as a Jeep Grand Cherokee, a Mazda CX-9 or a Land Rover Discovery? Hmm, each has its own distinctive styling, with the Jeep having brutish American looks, the Discovery boasting prestige British off-roader personality and the Mazda an elegant air that's way beyond its price point.

So why haven't I mentioned the Mercedes-Benz GLE or BMW X5? Because they're at least $20K more than the RX300 Luxury, which costs around $72K. If, however, you can stretch the budget to an RX 350 Sports Luxury then you will be crossing the $100K threshold into Benz and Bimmer territory. So let's talk about price.

Like the second-gen (H247) GLA, the EQA sits up high, offering lofty seating. That’s core to this range’s appeal, making getting in and out a less acrobatic feat compared to smaller and lower EVs.

The cabin is very similar to many of the second-generation MFA2 transverse-engine/front-drive-based Benzes like the current A-Class. That means solid looking and feeling doors and dash, upping the sense of quality. Very on-brand stuff.

This is a very modern and inviting interior, with those aforementioned screens set within a large rectangular binnacle. To the centre there are the trio of turbine-style air vents that still bring a spark of joy to the cabin (as well as seriously effective ventilation), along with the row of metallic toggle switches; both provide pleasing, high-quality sensory experiences.

It can lean towards overkill with a trashy night-club ambience if restraint is not exercised with the (configurable) coloured light show dotting the EQA's cabin. 

Not to everybody’s liking, but thankfully you can turn that stuff off, so no complaining necessary here.

You wouldn’t call the EQA particularly spacious with its curvy roof, snug sports seating, high waistline, narrow glass areas and thick pillars, but even 200cm-tall people should find enough legroom up front. There’s a sense of cosiness rather than crampedness.

The 350 4Matic’s sports seats do a great job holding and caressing you in, providing excellent bracing through tight corners. Three’s ample (powered) adjustment, including for lumbar and lower-back areas, as well as enough support for thighs. The cushions themselves are typically firm yet comfy. And the seats look great. 

The driving position is superb, ahead of a set of vibrant digital instrumentation choices that run the gamut of tastes, with the 'Classic' dial-like look and minimalist settings (reminiscent of Saab in its essentials-only display) included, so as to not scare away traditionalists. There is also a 'Progressive' screen that’s colourful and techy, though the info presented is a lot to take in.

What may not please conservative Benz buyers are the cheap-looking plastics dotted throughout the interior, along with the rattles that are regular companions, especially over less-than-smooth roads. 

This has been a bugbear of all MFA-platform vehicles for more than a decade now, and while better than in some previous models, the EQA at $100K should possess vault-like build quality, not squeaky trim.

And when will that small and flimsy gear selector stalk be binned?

Our test car’s ‘Hey, Mercedes’ voice control system was erratic at best, barely providing any assistance and regularly annoying/entertaining with misunderstood responses and laughably limited functionality. Was our example glitchy? Perhaps.

Storage is good. And, ergonomically, everything’s within reach of the driver, but there’s a lot to take in, with scattered switchgear.

It’s also worth noting that, if you’re new to the MBUX multimedia system, taking the time to learn its many functions and capabilities is advisable, as it’s more logical and simpler than the intimidating first impression suggests. 

A deft thumb is required for the steering-wheel spoke-actuated tabs for instrument data, but even technophobes ought to master it all eventually. 

The central part of the screen can be swiped to access the vast array of features, including the excellent audio system and detailed vehicle control settings.

Further back, passengers sit up high, giving a wide view of what’s happening up front, while the backrest is angled at just the right position. 

There’s not much fun to be had sitting on the raised middle bit, and shoulder space is seriously limited with three abreast, but otherwise, even adults should find sufficient legroom and headroom – even with the panoramic sunroof fitted.

Deep door pockets, face-level air outlets, reading lights and a folding armrest are to be found back there, though the latter includes a flimsy slide-out cupholder set that’s not worthy of the brand. 

Because there’s a battery pack in the rear half of the EQA, cargo capacity shrinks from the donor GLA's 435 litres to just 340L, while dropping the 40/20/40 backrests extends that into the cabin for a 1320L load space. Note there’s no spare wheel, just a tyre inflation kit.

People don’t buy these small crossover Mercedes models for space or practicality – that’s why the GLB/EQB exist – but the EQA isn’t too bad for the urban demographic which wants/needs a compact, high-riding EV with impressive ground clearance.

The RX300 is a five-seater SUV and, while it would be even more practical if there was a third row, the cabin is impressively spacious.

Have a look at my photo of the entry to the RX300's back seat – that's a big doorway  for a car. Parents will understand the value of wide-opening doors and these ones made it easy for my child to climb into his car seat and for me to buckle him up. Head and legroom in the back seats are also good, even for me at 191cm tall, while the flat floor makes it easy to 'scoot' across from one side to the other.

There are two cupholders in the fold-down centre armrest in the back and small door pockets, but storage up front is better, with huge pull-out door pockets, two more cupholders and a large centre-console bin.

There's a wireless charger in the hidey hole in front of the shifter, plus six USB ports on board - the rear passengers have two of their own in the back of the centre console and the rest are up front.

The second row doesn't come with climate control, but the directional air vents back there got a workout over the 40C days we had over summer.

The RX300's boot has a cargo capacity of 506 litres, measured to the top of the second-row seat back.

Now,  the media system. Yes, it's a tech thing, but I'm calling out it out as impractical. The functionality of the trackpad used to navigate around the screen is frustratingly awkward. I think 12 swear words in a row came out of me on one occasion (no child on board, obviously), just trying to use the sat nav. The layout of the display menu is also confusing and non-intuitive.

The RX300 received a stack of new equipment in the September 2019 update,  including a 12.3-inch media screen (previously 8.0-inches), Apple CarPlay and Android Auto, plus four additional USB ports (for a total of six), and a kick-open power tailgate. The list price is $71,920 before on-road costs.

Other standard features include a 12-speaker stereo with DVD player, sat nav, wireless charger, dual-zone climate control, 18-inch alloys wheels, LED headlights, proximity unlocking, heated wing mirrors, rear privacy glass, and powered front seats.

The update added more safety tech, too, along with some changes designed to make the driving experience better, which I'll tell you about below.

You're not getting the heated seats and the head-up display that you do on the F Sport, or the Sport Luxury's Mark Levinson stereo, but the value is great here,  especially compared to more prestige brands, which ask more money for the same or less equipment.

The Mazda CX-9 Azami lists for $69,303 and offers more features, but the Lexus brand has more luxury badge appeal than the Mazda, or the $69,950 Jeep Grand Cherokee Limited, while the $73,221 Land Rover Discovery 2.0 i4S beats all of them in the prestige stakes because… it's British. And they have a royal family.

The EQA 350 4Matic features an asynchronous motor and a single-speed reduction gear transmission under the bonnet, delivering 140kW of power and 385Nm of torque to the front wheels, and supported by a second, permanently excited synchronous motor located on the back axle.

'Dual E-motor' total outputs are 215kW between 7130-9506rpm up front and 5746-7661rpm for the rear motor, for a 520Nm torque total, from zero rpm. 

Drive is infinitely variable on both axles, for AWD capability. Tipping the scales at 2091kg (kerb), the 350 4Matic’s power-to-weight ratio is an impressive 103kW per tonne.

Result? Some six seconds is required to race from 0-100km/h, on the way to a 160km/h top speed.

The EQA employs a 66.5kWh lithium-ion battery pack fitted between the axles, with a maximum 11kW AC and 100kW DC charging capability.

Suspension is via MacPherson-style struts up front while a multi-link arrangement is out back. Steering is by electrically assisted rack-and-pinion.

The RX300 has a 2.0-litre four-cylinder turbo-petrol engine making 175kW and 350Nm, with a six-speed automatic transmission. This peppy four-cylinder gives the RX300 a completely different feel to the lethargic-but-powerful oomph of the RX350 and its naturally aspirated V6, even though it doesn't make a great deal more grunt, at 221kw and 370Nm. There's a difference in fuel consumption, too – find out how different below.

Is the RX300 all-wheel drive? Nope, it's a front-wheel drive. Only the RX350 and RX450h are AWD.

Using WLTP figures, the EQA 350 4Matic’s official consumption figure is 17.9kWh/100km. Maximum range is rated at 400km.

At pick-up, our EQA was displaying a 395km maximum range availability. After 273km of a mix of city, urban and freeway driving, our car showed 47km of range left, which means we could expect up to 320km in real-world driving scenarios. 

That did include some performance testing, which tends to suck out the kilowatts, by the way.

Our trip computer showed the vehicle had consumed 20.8kWh/100km on average.

Like the EQB, the EQA offers varying levels of energy recuperation to help recharge the battery pack. In ‘D Auto’ it figures out the level of resistance automatically, but drivers can also choose to do this manually via ‘D+’ that provides coasting, ‘D’ that brings mild regeneration off-throttle, and ‘D—’ that activates maximising regen for close to single-pedal driving. These are paddle activated.

Cables for home charging with three-prong outlets are included – an eight-metre long one plus a five-metre public charging cable.

Mercedes says a 100kW DC charger will take an EQA from 10-80 per cent charged in 30 minutes, while an 11kW AC public outlet needs seven hours, and at home using a regular 3.0kW 10-amp socket requires at least 34 hours.

Mercedes also offers a Wallbox with up to 22kW charging capability for your home or office from $1710, not including installation. That drops the charging time to under eight hours, which is ideal for overnight-home or all-day work charging scenarios.

Lexus says the RX300, with its 2.0-litre four-cylinder turbo-petrol engine, should use 8.1L/100km of premium unleaded after a combination of open and urban roads. My own testing over 375.4km - taking in motorways, city and suburban call-of-daycare drop-off-duties - had our RX300 using 11.79L/100km, measured at the petrol pump. The real-world results almost always exceed that of the manufacturer's claims so you can expect the V6-powered RX350, with its claimed 9.6L/100km, to have a much higher mileage again after the same kind of usage.

Probably the most impressive thing about the EQA 350 4Matic is how effortless, easy, and fun it is to drive, whether around town or out on the open road.

Slot the flimsy drive selector to D and this wastes no time moving off the line, streaking past 100km/h even more swiftly than the 6.0s official time suggests. 

The Mercedes powers along with strong acceleration available at all times. With such instant torque on tap, this is a treat weaving through traffic, zipping into rapidly closing gaps like a little go-cart.

At slower speeds, even in slippery conditions, the 350 4Matic feels glued to the road, possessing tons of grip wearing Pirelli P Zero 235/45R20 rubber, to help it carve through without breaking a sweat, pulled along by endless torrents of torque. Just a slight flex of your right foot has this car bounding ahead in no time.

Armed with nicely weighted and responsive steering and a planted yet agile chassis, all the makings are present for a premium electric hot hatch experience. 

However, there’s just a bit too much weight, which seems to manifest itself in somewhat top-heavy handling at higher speeds or through fairly tight corners. 

In such conditions, the Benz feels a bit nervous and a tad skittish, and not quite as composed as we’d hoped.

Disappointingly, while there’s regenerative braking using the steering paddles, it doesn’t quite bring the car to a full stop, but instead slows it down with enough force to wipe off most but not all of the speed. You can’t rely on full stop/go single-pedal braking, then.

Finally, there’s the suspension’s ability to cope with our patchy road surfaces. Over big bumps, ride comfort is fine, but smaller-frequency ones are all-too-often felt. 

There’s an underlying firmness to the chassis tune that’s in keeping with the EQA’s German heritage, but we expected more suppleness and isolation in a high-riding SUV equipped with adaptive dampers.

Plus, there’s more tyre/road noise than we’d like.

So, as a sprightly urban runabout, the EQA is ideal, with forceful acceleration and a slick powertrain. Backed up by the security of AWD, the 350 4Matic is great in inclement weather, too, with exceptional roadholding dynamics. But it isn’t quite as agile nor sophisticated and refined as we’d like a $100K Mercedes EV to be.

Good seats are the start of a good driving experience and I've not met a Lexus that doesn't have superb pews – from the uber luxury models, such as the LS500 and ES300, to sports cars such as the RCF or LC500, they all have supportive and comfy ones. Lexus somehow manages to  combine the comfort of a lounge chair yet still holds you firmly, all while placing you in a great driving position. The RX300 is no different. Large enough to fit me and my 191cm frame, yet bolstered enough to feel snug.

As for performance, the RX300, with its four-cylinder turbo-petrol engine with its six-speed automatic, is responsive and a bit hyperactive feeling. It's a very different sensation to piloting the RX350, which has a V6 and delivers its grunt in a more linear and lethargic fashion. Having driven both back-to-back I'd say the V6 and its eight-speed auto suits the RX personality better, but the 300 is a car that would have had a school report card that read: "Lots of potential, but lazy".

That said, plant the right foot and the RX350 will get the message to hurry up and can do the 0-100km/h sprint in eight seconds flat. The RX300 is keen but can't match it, with  a time of 9.2 seconds.

Either way, the ride comfort is excellent, although body control could be better - the speed bump and roundabout route I take to do the preschool drop off caused it to  get the wobbles, but give the RX300 a motorway and it'll cruise beautifully.

Forward visibility is good but vision through the tiny rear-quarter window (it's even smaller than it looks) while reverse parking isn't great.

The RX300 scored the maximum five-star ANCAP rating when it was tested in 2016. The September 2019 update added more safety tech to the RX300, including nighttime pedestrian detection and daytime cyclist detection for the AEB system, while the adaptive cruise control was given lane-trace assistance and road-sign recognition. This is on top of the already standard safety equipment, such as a reversing camera, blind-spot monitor and rear cross traffic alert.

Ten air bags, along with auto high beam, front and rear parking sensors, two ISOFIX points and three top-tether mounts for car seats and a space-saver spare wheel round off a comprehensive safety package.

Mercedes-Benz offers a five-year/unlimited kilometre warranty.

The battery pack warranty is also industry-standard, valid for the usual eight years/160,000km. Service intervals are every year or 25,000km.

There is no capped-price servicing, however buyers can purchase up-front when new to save money. 

The EQA 'Service Plan' starts at $1600 for the first three years/75,000km (whichever occurs first), $2200 for four years and $2650 for five years.

Lexus recommends servicing the RX300 annually or every 15,000km, with the first three services capped at $595.

The duration of Lexus's factory warranty is four years/100,000km, which is a bit longer than BMW and Benz's coverage, but behind the five-year/unlimited-kilometre warranties of the mainstream brands.
