BMW 530E vs Mercedes-Benz E300

What's the difference?

The G30 5 Series is an excellent car and unless you're looking for the serious punch of the V8 M550i, or want to run with the cops in the diesel, the 530e is a great option. No slower than the 530i, well-equipped and that rarest of things, a truly elegant BMW. Nobody buys a BMW with an eye on the budget, so at this level, the $3000 gap is nothing to worry too much about. For EV-sceptics, the range anxious or just for someone who just can't take the full EV plunge now, a PHEV is a great bridge between the two worlds.

And if nothing else, it's not a giant SUV.

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.

The G30 5 Series dates back to a time when people thought the grille on this was A Bit Much. How wrong they were. The 5, like the 3, used to be part of a clutch of executive sedans that formed the backbone of the company's expansion and success from the 1980s onwards. That means the styling is never too adventurous and even Chris Bangle's E60 5 Series, while striking, was not particularly controversial.

The only problem with the G30 is that it's hard to distinguish from its predecessor, but that's not a real issue when you see how elegant this car is. Easy on the chrome, proportional grille, big wheels, it's a proper smooth operator, visually speaking.

The cabin is holding up nicely and fits with the rest of the BMW range. It's impeccably well built, full of nice materials and even the wood trim is all right. The black Nappa leather is quite lovely but I can't tell you what the standard stuff is like, so you'll have to work that one out for yourself. It's very calm in here, with a good balance of buttons and screens with which to operate the car and while it doesn't have the you-beaut wow of its E Class rival, with its two massive slabs of screen in front of you, it has plenty to offer.

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.

The 5 is almost five metres long, so as you might expect, it's big inside. Back-seat passengers have a ton of space to play with and even three across back there is doable for a distance. The outboard seats have some nice shapes to them, too, so they hold rear passengers in if the driver gets a bit ambitious. Loads of legroom, good headroom and very importantly, a good view out through the big side windows. Properly comfortable, then.

Front and rear passengers each score a pair of cupholders for a total of four as well as the same number of bottle holders. The centre-console bin is long and shallow, but does feature a USB-C port. The wireless-charging pad also has a USB-A port for those without the functionality and/or a phone too big to fit. Both the cupholders and charging pad have a sliding cover.

The boot is smaller than the standard car's as there is a lithium-ion battery hidden underneath the now-sloping floor. With 410 litres, it's smaller than a 3 Series' but it doesn't look that small. There is also a spot for the charging cable and its bag behind the left wheel arch.

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.

The 530e comes with a 2.0-litre four-cylinder turbocharged engine developing 135kW and 290Nm, with the eight-speed ZF automatic sending power to the rear wheels. The electric motor spins up 83kW and 230Nm, also driving the rear wheels. When everything is working together, the combined output is 185kW and 420Nm, which delivers a quick 6.1-second dash to 100km/h, which isn't mucking about.

You can choose four drive modes. EV will (mostly) drain the battery, Hybrid will keep the two working together and Sport will deliver the most power. And drain the battery, albeit more slowly. Adaptive works the averages and decides what you need or want by how frisky you're being with your driving style.

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 12kWh battery takes up the same amount of space as the old one, but has more capacity, extending its EV range. The claimed EV range is 57km on the WLTP standard. 

The iDrive system has a bunch of settings that you can play with to squeeze more out of the silent-running mode and there's also a battery-charging mode button to force the ICE to charge the battery while you're on the move. Also useful is a timing system, so you can schedule when the car charges to take advantage of the cheap power available in the dead of night.

Recharging is easy but sadly a bit slow off a domestic power point. Having said that, if you plug it in after a day's commuting, you'll be topped up to 100 percent overnight. It's a long charge, but it's not as if you'll be stranded if you forget. You can get a wallbox, but there's not much point.

The fuel tank is just 46 litres. The WLTP combined cycle figure is a laughable 2.3L/100km. On that official figure, you'll cover an unlikely 2000km. My week with the car, which included 70km on EV-only power with one charge off my solar panels, got me an indicated 6.1L/100km in a mostly suburban week of driving. So based off that, you'll get about 530km from one full charge and a full tank, which is a bit confusing. Keep charging and, if you're an average Australian who travels little more than 30km per day, you won't use much petrol at all.

Having said all of that, out on the freeway, you'll probably slide towards that 2.3L/100km and make it from Sydney and Melbourne on a single tank. Just.

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.

The reason I like PHEVs as a tool for pushing people towards electrification is about more than the fact that it will likely cure buyers of range anxiety once they're realistic about their actual car usage. I mean it does do that, but it's more about the fact that PHEVs drive like a normal car, with few exceptions.

In EV mode, the acceleration is swift but not that brutal, YouTuber-friendly thrust EV fanboys use as proof that legacy car makers are dead. It's all very serene and very, very quiet as you move from traffic light to traffic light in near silence, while more than keeping up with traffic. The blue of the dashboard indicates your progress and the iDrive screen can keep you updated with power consumption.

The switch between EV and ICE propulsion is very smooth and it's almost like BMW has been doing this forever. You'll also discover an appreciable lift in performance, more in line with the M Sport badges. BMW's engineers have done nothing to make the 2.0-litre petrol sound better than a whirring mixmaster, though.

Slightly less M Sport-ey is the suspension. While there's absolutely nothing wrong with it, the adaptive dampers never dial things up too much for the average motorist. Granted the 5 will leave just about anything this size for dead as far as driver involvement goes, but it certainly keeps the dial closer to comfort than, say, the M550i does. Once again, it's a serene thing to get around in and passengers will love the quietness and easy flow of conversation. Or the lovely sound from the harmon kardon speakers.

You don't have to try too hard to cover a good chunk of the claimed 57km of EV range. Realistically you'll get close to 45km, even after my colleague Matt Campbell drained 20km of charge in a six-kilometre trip that he maintains was driven gently (snigger) and normally (guffaw). Without trying too hard, I managed 41km in pure EV after his attempts to ruin my numbers (not really, but I do enjoy the amusing false narrative).

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.

BMW really needs to up its game, as do Audi and Porsche (among others). Munich is still sticking with a three-year/unlimited-kilometre warranty while German rival Mercedes is up at five years and Japanese competitor Lexus four. You do get three years roadside assist thrown in.

All 5 Series (excluding M5) are eligible for service plans. For $1950, you're covered for five years/80,000km of servicing. As with most BMWs, servicing is based on how you drive but really, if we're being honest, the car will get you into the dealer once every 12 months or 15,000km. Roughly.

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.
