BMW 530i vs BMW X3

What's the difference?

Not all superheroes wear capes, and we're proud to report the 530e does its bit for green motoring without feeling the need to shout about it. And with no price or specification penalty, it's easier being green than ever before, and the pricing of this BMW really puts the cat amongst the canaries.

If a BMW X3 is for you, then we have no quarrels with that. It’s a better all-round vehicle than the one it replaces and represents better value. And even though BMW mandates a hybrid driveline, there are still some significant choices within that framework.

By all means buy the M50 if you crave the rush of acceleration that almost 300kW can provide. And if efficiency is your altar of choice, then the plug-in 30e makes a lot of sense, too.

But even if you can afford either of those two more expensive variants, whatever you do, don’t dismiss the entry-level 20 model. At least drive it alongside the others and then make a decision based on all the facts, and not the assumption that entry-level equals the car you afford rather than the car you want.

It might be cheaper, but there’s absolutely no doubt that the 20 model is the one that shines and arguably makes the most of the opportunities BMW’s latest tech offers.

Sometimes less really is more.

Crucially, there's nothing weird about the way the 530e looks. While some green cars look like they've been designed by one of the kids from 3rd Rock from the Sun, the 530e looks much the same as the rest of the range, save a few tiny but telltale giveaways - like the e-drive badging outside, and what looks like a bonus fuel flap tucked in behind a front wheel that houses the whole plug-in bit.

And we really, really like it. It's elegant and statesman-like from every angle, and looked especially important in the deep-blue colour of our test vehicle. It's not over-designed, with body creases used sparingly, and the occasional glint of polished silver that rings the windows and the grille adds a final sense of shininess to an understated design. 

Inside, there's more going on than you might normally find in a BMW. The hugely complicated digital display screen now includes everything from battery charge, power usage to the usual assortment of speedometers and petrol readouts. 

It doesn't feel overdone or crazily festooned, but there's more at play here than in your usual BMW.

The dash is busy, too, with a wide screen emerging from a centre stack that also houses a CD player and a digital aircon setup, which in turn sits above a complex centre console from which you can alter driving settings, control the multimedia or cycle through electric modes. It doesn't feel overdone or crazily festooned, but there's more at play here than in your usual BMW.

Elsewhere inside, the seats are beautifully designed, with a quilted leather highlight through the middle, while the gloss-black strip that lines the dash hides a dual strip of ambient interior lights that also runs across all four doors.

It might be badged an X3, but this is no small vehicle. In fact, it’s bigger than the original BMW X5 (which set the tone for this entire market segment) with a length of 4755mm (4667mm for the first X5) and a width of 1920mm (1872mm). That said, it’s 25mm lower than the outgoing X3 in a move to emphasise its sportiness. Shorter it may be, but it’s also 16mm wider on the front track and 45mm wider on the rear than the outgoing model.

BMWs latest styling cues also appear in the new car, including the large, split-kidney grille that, for Australian-delivered cars, is also lit around its edges. The short overhangs that characterised the original X5 (and soon characterised this whole BMW genre) remain, and the T-graphic LED tail-lights round out the stylistic touches.

The other thing we noticed (and we’ve seen it on other cars recently) is a panoramic sunroof that doesn’t actually open.

As the world's motoring tastes shrink faster than a lap-banded Clive Palmer, it's easy to forget the joys of the full-size sedan, but the space for passengers and luggage in the 5 Series will have you questioning your downsizing ways.

Upfront, there's plenty of room between front-seat riders, who will also share two smallish cup holders, along with room in each front door for bottles. There's also a dedicated wireless charge pad (which, because of its tight design, is crazy difficult to actually remove your phone from), but you'll also get two USB points and a power outlet that's hidden in the sizeable centre storage bin as standard fit.

Backseat riders get heaps of space, both in width and in leg room behind the front seats. And there's twin air-con temp controls and twin power outlets, too. But middle-seat passengers will be forced to sit with their legs on either side of the raised tunnel, which will definitely impact on comfort.

The boot's still sizeable, despite shrinking slightly to house the battery/fuel tank setup

Best to ditch the fifth passenger, then, and deploy the pull-down seat divider, which also houses two cup holders. Finally, there are three ISOFIX attachment points, one for each seat in the back.

The boot's still sizeable, despite shrinking slightly to house the battery/fuel tank setup (the tank has been moved further back to accomodate the batteries), and can be adjusted to be a flat load area if you'd like, offering up to 410 litres with the rear seats in place.

Cabin space is plentiful in the X3 with loads of room in the front, possibly thanks to the dashboard that is pulled back from you with only the twin screens and steering column offering themselves up to the driver. Even the air-vents are somewhat hidden. There’s good vision out and the seats themselves are lovely. The step into the cabin feels to be at just the right height, too; not too high, not too low.

Rear seating is good, too, although the X3 will always be better as a four seater than five thanks to the shape of the rear bench, but the glass roof opens the space up and there’s plenty of charging points and storage nooks. The sun blinds on the rear-side windows of the more expensive versions should be standard kit on every car sold in Australia.

We’ll take exception to the new gear-selector which doesn’t have a defined Park position and instead relies on applying the park-brake to engage Park. But the ambient light and contrasting cabin colours are a bit of a breath of fresh air.

There are levers in the cargo area to quickly fold the rear seats (60:40) at which point luggage space jumps from 570 litres in the mild hybrid cars to 1700 litres. The battery-pack of the 30e model means that luggage space starts at 460 litres and can be expanded to 1600 litres.

The latest version of BMW’s sometimes controversial iDrive operating system is simpler and easier to use than before and supported by a new operating system, but there’s still some familiarisation necessary. One improvement has been the addition of QuickSelect which works somewhat like the old favourites button system and gets around the need to drill into menus to access the functions you want.

A head-up display is a terrific addition, although where some displays are more tolerant of polarised sunglasses, the HUD in the BMW didn’t like mine and went dark at the most inconvenient angles.

None of the X3 variants feature a spare tyre of any sort. The 19-inch tyres on the base grade are run-flats, while everything else gets a repair kit for roadside emergencies.

If you want to tow, the good news is that all X3 variants can do so. But you will need to purchase the $2200 towing package which enables the X3 to haul a trailer weighing up to 2000kg with a maximum tow-ball down-weight of 200kg.

The new X3 range kicks off with three distinct models. There’s the entry-level 20 xDrive at $86,100, the 30e xDrive at $104,100 and the big-hitting M50 xDrive at $128,900, all before on-road costs.

Both the 20 xDrive and the M50 xDrive feature a 48-volt mild hybrid driveline, while the 30e xDrive goes all the way with a plug-in hybrid (PHEV) layout. All variants also feature BMW’s permanent all-wheel-drive system.

BMW claims greater standard equipment than ever before, and even the entry-level 20 xDrive has plenty of kit including 19-inch alloy wheels, tri-zone climate-control, the virtual cockpit screens with a curved central info screen, a six-speaker, 100-Watt stereo, acoustic glass, auto headlights, an auto tailgate, keyless entry and start, digital radio, powered and heated front seats, wireless Apple CarPlay and Android Auto and wireless phone charging.

The PHEV model adds 20-inch alloys, the M Sport package including blue brake calipers, and a leather steering wheel, as well as the Comfort Package which adds heated seats for the second row of outer seats, a roller sun-blind for each rear-side window, ventilated seats, a heated steering wheel, tinted glass and a luggage net. The 30e also gets parking assistant, a panoramic sunroof (a non-opening one), and a surround camera system.

Move up to the M50 variant, and you’re in for no-cost metallic paint, 21-inch alloys, a 15-speaker stereo, quad exhaust tips, M-specific details such as the mirror caps and aero add-ons. You also get a range of kit as standard that comes as an extra-cost option on the other two variants. Those include the enhancement pack that includes an alarm system, surround sound, M Sport Pro Package (various trim highlights, red brake calipers, M seat belts) and the Comfort Package that is also standard on the 30e.

The value headline is that, compared with the previous model, some variants of the new car are actually cheaper on an apples-with-apples basis. The base model car in its previous form was, by the time you added the now-standard M Sport package, dearer at $88,100, and the previous 30e optioned to include the standard kit the new car has, (heated rear seat, acoustic glass, roller blinds and more) was also (much) more expensive at $111,800. And although the M50 model in its previous guise was slightly cheaper at $126,800, it lacked the hybrid driveline, metallic paint and M Sport Pro package the new car has as standard.

Drift around in pure EV mode and you'll be relying on the 530e's 83kW and 250Nm electric motor, which will provide what BMW refers to as "between 28 and 32 real-world kilometres".

Run out of range, or simply use too much throttle, and the 2.0-litre petrol engine comes into play, adding 135kW and 320Nm to the mix. All up, that's 185kW and 420Nm - respectable numbers by any measure, and enough to match the petrol-powered 530i's zero to 100km/h sprint of 6.2 seconds.

That power is fed through an eight-speed automatic transmission before being sent exclusively to the rear wheels, where it belongs.

Hybrid tech across the board is the key phrase here, with the base-model 20 xDrive fitted with a mild hybrid electric motor and battery pack that works in conjunction with the 2.0-litre, turbocharged petrol four-cylinder engine. Power is 140kW and torque 310Nm. Like most mild hybrids, the electric motor offers power regeneration during braking, a mellow (by EV standards) kick in the pants during take-off and acceleration and also acts as the car’s starter motor.

The performance flagship, the M50 xDrive taps into the same technical philosophy with a mild hybrid augmenting the turbocharged six-cylinder inline petrol engine. In this case, however, peak power is a hefty 293kW and torque maxes out at 580Nm.

The most technically adventurous X3 is the 30e xDrive which uses plug-in hybrid tech to offer a claimed 91km of electric driving, about twice that offered by the original X3 PHEV it replaces. When the same 2.0-litre four-cylinder petrol as fitted to the 20 xDrive, and the electric motor are humming along together, there’s 220kW of power and 450Nm for the taking. The PHEV X3 can run in purely electric mode at up to a claimed 140km/h.

All variants use BMW’s familiar eight-speed automatic transmission and in each case, drive is sent to all four wheels on a permanent basis. Interestingly, the 30e and M50 versions package their electric motor as part of the engine-transmission combination. The 20, meanwhile, places its electric motor externally, as part of the drive-belt rotating assembly.

The M50 model has an M button that unleashes the full performance with one touch, and features an electronically locking rear differential in the interests of high-speed turn-in.

Adaptive suspension that varies the degree of damping is also part of the package on each X3 variant.

Like a Facebook relationship status, it's complicated. The 530e will sip a claimed combined 2.3 litres per hundred kilometres on the claimed/combined cycle, which is amazing for a car this size. Better still, it seems genuinely achievable - at the vehicle's launch, our own Richard Berry recorded a stunning 2.0 litres per hundred kilometres on a short test route.

But that's with a full load of battery charge on board. For our week with the 530e we were unable to actually plug it in (living in Sydney, I can't afford a garage), so once the initial battery charge had been used we were back to mostly petrol power. Unlike some other plug-in hybrids we've driven, we found it very difficult to recharge the battery to any meaningful level using regenerative braking, so once we were flat we stayed flat. If we had plugged it in, it would have been a two-hour recharge using a specialised wall unit, or about four hours using a normal plug.

As a result, though, our fuel use was closer to 7.0 litres per hundred kilometres after some considerable real-world testing.

As you might expect, the PHEV 30e model is the efficiency superstar of the X3 line-up with an official combined test figure of just 1.6 litres per 100km and 38 grams of CO2 per kilometre. The four-cylinder 20 xDrive is not bad for its size at 7.5L/100km (and 171g), yet the bruising six-cylinder M50 version with all that performance is not too far behind with an official figure of 8.2L/100km (187g).

The 30e PHEV features a selectable battery-saving mode as well as the option of forcing EV-only running. It features a 19.7kWh battery and BMW claims it can charge using a three-phase, 11kW socket from empty to full in two hours, 15 minutes. It does not make use of fast-chargers.

Exactly how far you’ll travel in the PHEV model will depend hugely on how and where you drive. On long, open road journeys, fuel consumption won’t be much different to the others, but with just a 50-litre fuel tank, it’s range won’t be stellar. But in urban running where the batteries are being recharged for free as you brake, the difference will be significant. Meanwhile, with a 65-litre fuel tank in the mild hybrid grades, the theoretical range (based on the official fuel number) is 865km and 765km for the 20 and M50 respectively.

While BMW recommends premium fuel for maximum efficiency, it also says that each X3 variant will not be harmed by the use of standard ULP if that’s all you can get hold of.

There's so much to like about the way the 530e sets about saving the world, and that's mostly because it doesn't shout about it, either to the driver or the outside world.

It's very much an underpants inside its pants superhero, which makes us like it even more. Set off in EV mode, and the 530e will drift silently away from the curb, burning battery power over fuel for as many as 30(ish) kilometres. But equally important, the shift from green to gas is largely imperceptible, with the petrol engine joining in willingly when you ask it to - usual via a prod of your right foot.

It is so effortlessly smooth that you need to really pay attention to notice the eight-speed 'box changing gears at city speeds, and it's commendably quiet, whichever drive mode you're in.

Downsides? Well, it doesn't feel quite as sharp as it's conventional-engined siblings. The batteries add around 230kg in weight, which never helps, and it all feels a little softer and a little less dynamic, even with Sport mode engaged. BMW assures us the adaptive suspension setup and tune is identical, but the 530e feels noticeably softer when you tackle a twisting back road. And that encourages you to use your right foot a little more, which in turn negates the whole electric thing in the first place.

One of the great joys of BMWs has always been their ability to transform from cosseting comfort to rear-drive rocket when you want them to, and you can't help but notice the 530e isn't quite up to that challenge. But if your intentions are mostly city- and freeway-based, then this plug-in BMW is almost indiscernible from its petrol-powered sibling.

Big heavy SUVS like this one haven’t always been too dainty on their feet. The extra bulk and height mean suspension has to be firmer, the big wheels and subsequent loss of tyre sidewall depth plays against ride quality and before you know it, the compromises have piled up and the driving experience has gone to hell.

This time, however, BMW’s claim that the X3 was designed from the start as an SUV and not converted from a sedan platform seems to hold water. There’s an overall greater sense of cohesion in the way the car steers and flows through corners and faster bends. The steering feel and feedback are a big part of that, too, and the whole seems at least as great as its parts.

The M50 is, predictably, a rocket with loads of accessible acceleration and a great noise while you’re enjoying it. That said, the 21-inch wheels and tyres don’t do anything for ride quality, but it remains an entertaining performance car in a familiar, ICE kind of way.

The plug-in is also perky with its 220kW on tap, but it’s less old-school and more techy. And while you can’t pick the point at which ICE hands over to electric and vice-versa, sensitive drivers will absolutely know that there’s a big dollop of electrical assistance when your right foot starts asking the tough questions. It definitely feels more overtly hybrid, though that shouldn’t be any kind of surprise, purely because that’s precisely the case.

Which brings us to the 20 entry-level grade. And while it’s going to be a controversial statement, this emerges as the most cohesive, rounded variant of the new X3. There’s something in the way the fizzy, bubbly (but very smooth) 2.0-litre four-cylinder provides more than enough urge, but never threatens to dominate the dynamics.

With less weight over the front wheels than the M50, and less weight overall than the PHEV, the 20 corners flatter, steers more intuitively and is simply more fun more of the time. Even on the optional 20-inch tyres, it rides better than the others, too, and might even be better again with the standard 19s other than the fact that those are run flats and we didn’t get try them.

The X3 – not too surprisingly – runs to all the latest driver assistance programs starting with autonomous emergency braking (AEB) that can identify pedestrians and cyclists. There’s also front collision warning, lane departure warning, parking assistant and a surround camera system. There’s also lane-keeping assistance which is calibrated perfectly and should be the standard for this type of otherwise intrusive technology.

You’ll also find front and rear cross-traffic warning, adaptive cruise control and tyre pressure monitoring.

The X3 hasn’t been ANCAP tested and there’s no real likelihood of that happening in the future.

Like the rest of the 5 Series range, the 530e falls under BMW's three-year, unlimited-kilometre warranty. There are no set service intervals, either, with BMW using what it calls 'condition-based' servicing. In other words, the car will tell you when it requires a trip to the service centre.

The batteries are covered by a separate warranty covering six years or 100,000km.

BMW’s warranty on the X3 is the company’s usual five-year/unlimited kilometre deal. But in this case, there’s also a six-year/100,000km warranty on the high-voltage battery.

Also typical for BMW is the service interval which is not a set time or distance and instead is determined by how the car has been used. It’s called condition-based servicing and it’s nothing new at BMW.

There’s also capped-price servicing available. For the X3, the five-year/80,000km service package is $2475.
