Mercedes-Benz E300 vs Tesla Model Y

What's the difference?

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.

If you like the five-seat Model Y, then you'll like the six-seat L version even more. I think this the best example of Tesla's electric SUV to date, and the cabin layout just makes a lot of sense, and would suit plenty of families who don't need to squeeze someone into a compromised middle seat.

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.

Spoiler alert - it looks a lot like a five-seat Model Y, doesn’t it, albeit a slightly bigger one. And you’d have to be a bigger Tesla head than me to immediately spot the differences at a glance.

The wheelbase is longer, the rear doors are bigger as are the rear 3/4 panels and the roof line is higher, helping with headroom in the third row.

Still, safe to say if you like the look of the five-seat Model Y, you’ll like this one. And if you hate it, well, good luck.

The alloys are 19-inch and shaded by the aerodynamic caps and there are light bars front and rear which debuted on the updated five-seat Model Y when it arrived mid-last year.

The bigger changes are inside, of course. I promise we’ll get to the second and third rows in the Practicality section, but let’s talk about the look and feel first.

There’s a love/hate relationship with Tesla’s stripped-back aesthetics, and I’m probably somewhere in the middle. I like the airiness of the space in the cabin, and I think it feels nicely put together, and I really dig the contrasting fabric used on the doors and dash which add a little visual interest to the cabin.

But I hate using the central screen to select a gear and I hate not being able to see how fast I’m going without turning my head. A head-up display would work wonders in the Model Y L cabin.

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.

Captain’s chairs are simply a more luxurious version of second-row seating. With that there is no argument and the heated and cooled chairs that occupy the second row of the Model Y L are pretty good examples of them.

Space, both knee and headroom, is ample, and you can adjust each seat individually if you want to grant a bit more space to any third row occupants. Armrests deploy at the push of a button — as do the two hidden cupholders — and it really is easy to settle in and get comfy.

The third row is a bit more hit and miss. I’m 175cm and found I had enough legroom and headroom, but the big plastic mouldings that emerge from each side of the Model Y (which house a cupholder) are a miss. They end up pushing you into the seat next to you, and I can foresee a lot of arm rubbing with anything like two adults back there.

Also confusing is how to actually get out of it. You can fold the seat in front of you flat, but then you have to climb over it. I found it easier to just walk out between the seats.

There are another two USB-C ports in the rear row and you get air vents but no temperature controls. 

The Model Y L stretches 4969mm in length, 1668mm in height and 2129mm in width, which is roughly 18cm longer and 4.5cm taller than the five-seat model. The extra space doesn’t sound like that much, but start dropping rows and you find a heap of storage space.

Both the second and third row stow electronically from the boot, but with them in place you’ll find 420 litres of storage in the double-layer boot. Drop the third row, and that number grows to 1076 litres. With the third row folded there is a massive 2423 litres of space. The frunk serves up another 116 litres.

There’s also room (and the ISOFIX attachment points) for four child seats.

The Model Y L sits smack bang between the $68,900 Long Range AWD and the $89,400 Performance, setting you back $74,900, before your on-road costs. It’s also the only three-row option in the Tesla family.

Aside from people movers, we’re not swimming with options in the three-row electric space, either. The Kia EV9 will get it done from $97,000, the Hyundai IONIQ 9 starts from around $120K and the Volvo EX90 is more expensive again (from $124,990).

Anyway, in Tesla land, the Model Y L rides on 19-inch alloy wheels, has a glass roof, automatic wipers and Tesla’s smartphone access key, as well as the little credit-card swipe.

Inside, there’s a 16.0-inch central screen that handles everything. And I mean everything. It's your gear selector, your speedometer, and everything else, too. There’s no Apple CarPlay or Android Auto, but you can access things like Spotify and podcasts through the in-built apps and the on-board navigation system is a good one, too.

All of that pairs with a 19-speaker sound system, and there are dual wireless charge pads. All three rows of seats are heated, while the first and second row get ventilation, too.

A second 8.0-inch touchscreen in the middle row then handles things like the seat heating or cooling, music and games to amuse the kids. And the Model Y L also debuts V2L, or Vehicle to Load, for Tesla in Australia, using a connector in the external charger.

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.

The Model Y L gets Tesla’s dual-motor AWD powertrain, with two electric motors producing a total 378kW and 590Nm. That’s enough, Tesla says, to knock off the sprint to 100km/h in five seconds flat.

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.

Tesla is always a little vague when it comes to the size of its batteries, but reports point to the Model Y L carrying a 84Wh (useable) NMC battery.

Whatever the specifics, the range is strong, with Tesla promising a 681km driving range on the WLTP combined (urban/extra-urban) cycle.

It’s also set up for 250kW DC fast charging, which should see you take on 288km in 15 minutes, according to Tesla.

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.

Honestly, it feels like the Tesla Model Y has grown up. I didn’t love earlier iterations of this car and I found the Performance to be fast but lacking any emotional fizz.

This one, though, feels solid and composed, and the power on tap (of which there is ample) is more about effortless progress than it is attempting to offer sports car excitement.

The steering is now nicely weighted and feels direct enough without being too sharp, and the cabin is well insulated, with often the slightly off-putting sort of rubbing noise the steering wheel makes when you turn it the only intrusive sound.

One drawback is a ride that definitely errs on the side of firm. This Model Y L gets electronic damping designed to iron out some of the more jagged stuff, but it still feels brittle in places, and you can definitely feel some sharpness in the cabin. Now, to be fair, it’s not too firm for me, but it might be for you.

Another is a bizarre turning circle which constantly reminds you you’re driving a big bus, especially when you try to complete a tight three-point turn.

But despite its stretched dimensions, I found the Model Y L easy to drive and park in the city, and once you're up to speed with Tesla's operating system (there's no Apple CarPlay or Android Auto), then the screen is pretty easy to use, too.

The Model Y L gets the same maximum five-star ACNAP safety rating as the rest of the Model Y range, with nine airbags (up from seven in the five-seat model), and things like AEB (Auto Emergency Braking), lane-keeping assist, 'Forward Collision Warning' and blind-spot monitoring all along for the ride.

Interestingly, the curtain airbags from the five-seat version haven't been replaced, with coverage still only extending to the second row. New airbags have instead been added for third-row occupants.

One more analogue quirk of the Tesla Model Y L is the thick B-pillar, which does a good job of almost completely obscuring driver-side blind-spot checks (for those of us who still like to do those manually).

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.

Tesla warranty is a these-days-underwhelming five years and unlimited kilometres, while the high-voltage battery is covered for eight years or (a wildly specific) 192,000km.

There’s also five years' of roadside assistance, including puncture repair (a good thing, given the lack of a spare wheel). I also couldn’t find a puncture repair kit and later research suggests Tesla sells them, rather than provides them as standard.

Tesla servicing is condition-based, so there’s no fixed schedule, with a summary on the car’s touchscreen providing a record of when vehicle maintenance was last carried out and prompts for when they should be performed next.

In the absence of a combustion powertrain the emphasis is on things like wheel rotation, balancing and alignment, brake fluid testing, air-con servicing, camera precision, radiator cleaning and high-voltage battery maintenance.

Expecty a ‘Vehicle Health Check’ to come in under $300 with ‘General Diagnosis’ at around $270 per hour.
