BMW 630I vs Xpeng G6

What's the difference?

This isn't a car for everyone's tastes, but if you fit in to the buyer group that just doesn't really know what they want in a luxury car, it could be the perfect fit for your family. The 6 Series GT is a practical large prestige car, albeit one that will likely find very few buyers.

You never know quite what to expect when you jump into the first model from a brand-new brand, but the XPeng G6 was a pleasant surprise. And at this price, with these features, it should really give Tesla Model Y shoppers something to think about.

There is no denying the 6 Series GT looks better than the old 5 Series GT. It isn't as frumpy, it looks more sporty, and to me it appears to have grown into its identity with more conviction than its predecessor.

That said, I don't necessarily like the look very much - it's a bit like a BMW X6 that has been rounded off a little and lowered down substantially. But I can appreciate some of the finer design aesthetics that it offers up: the frameless windows are a nice touch, and the swooping roofline looks smoother than a duck's back.

Other things like the active grille shutters and the air breathers ahead of the front doors are nice functional touches, and to my eye it lives up to BMW's hope of it looking "smooth but muscular". You can get the 630i with either the M Sport package, like you see here, or the more sedate Luxury Line, which is, well, more luxurious looking.

The M Sport styling and equipment package you see in the images here - with M aero kit and 19-inch wheels (ours had been upgraded to optional 20s) - help out with the athletic look of this very big vehicle.

It's huge in fact. The length of the 630i is 5091mm long, it measures 1902mm wide and sits at 1538mm tall, with a lengthy 3070mm wheelbase.

All that equates to a lot of room in the cabin, and what a sumptuous and delightful place it is to be - leather, wood and plush finishes abound.

There’s more than a little Tesla Model Y in the XPeng’s exterior design, with the two sharing the same kind of soft-edged, swept-back SUV styling. 

It helps make the XPeng look familiar and inoffensive, and while I wouldn’t go so far as to call it ground-breaking, I think it has enough exterior flourishes to break up the body work, and I don’t mind the way it looks, and the way it sits on those big alloys.

Inside, it’s a spacious and pretty stylish space. This giant screen is super responsive, and is easy enough to navigate, with the key functions (like climate) glued to the bottom of the screen so you don't have to paw through menus to access them. The idea begins to fail when you have Apple CarPlay or Android Auto active, though, as you have to revert back to the car's home screen to access anything.

The XPeng uses its steering wheel controls to access air-con fan and temp controls as a kind of shortcut, but confusingly they change to distance adjustment when you’ve got the cruise control on. An easier, and much better solution would be to bring back buttons.

I also don't love the stalk-style gear selector, which doubles as a cruise control activator, and, with a double pull, as your autonomous helper. It just feels super old-school in a vehicle this modern.

What is a massive win though is the driver screen. Tesla fans can scream minimalist aesthetics all they want, but the drive experience is simply better when you can see your speed and other key info right in front of you.

Now, I said before that this is a bit like an X6, but it has heaps better interior space than that SUV.

As soon as you slide into the driver's seat, you feel like your inside a large car. The cabin space is plentiful, and there's an abundance of storage on offer, too: there's a split-lid armrest between the seats, a pair of cupholders, a phone storage nook with wireless charging, and big door pockets with bottle holsters.

In the back you have access to door pockets, a flip-down armrest with cupholders (that middle part of the seat can fold down completely to allow storage of longer items), and there's excellent room on offer. How many seats in the BMW 6 Series GT? Five - like, five full-size seats.

Because the roofline doesn't rake as sharply as a four-door 'coupe', headroom is excellent for adults (even of the 183cm variety, like myself), and legroom and toe room are equally very good. This is bigger in the back than a 5 Series, but maybe not as plush as a 7 Series… so I guess it makes sense numerically for its nomenclature.

Of course you get climate control in the front (and in the rear if you option it), and the materials are excellent. The media screen is tablet-style, proudly displaying 10.25 inches of high-def real estate that is both touch-capacitive and controllable by way of the central rotary controller with touchpad. And get this - you can even use gestures to control certain elements like volume, swiping and changing tracks… but you have to option that.

The fully digital instrument display is bordered by a set of incomplete dial rings, which is just odd. BMW, back yourself - your buyers can handle just having a digital screen in front of them, particularly when it's as good as this one.

This grandiose hatchback's boot is commodious - with the back seats in place it has a huge 610 litres of cargo capacity, which extends to 1800L with the 40/20/40 seats folded down using the quick release levers in the boot area.

There is no spare wheel (the BMW range is fitted with run-flat tyres) but it does have a secondary hidden storage area under the boot floor for hiding items or stowing wet gear, bathers/swimmers or muddy clothes.

For context, the X6 has 580L seats up, 1525L seats down.

At 4753mm in length, 1920mm in width and 1650mm in height, the XPeng fits into the fast-growing mid-size electric SUV space. 

And it ticks a lot of practicality boxes, like with its 571-litre boot, swelling to 1374 litres with the seats folded. But its real party trick is in the back seat, where the space is properly massive. 

I have another mid-size SUV, powered by a petrol engine, at the moment and our baby seat presses against the back of the passenger seat. In this it feels like I could fly a kite in the space between them.

It’s the same for passengers, too. Honestly, the real estate on offer is massive, and that includes for the middle-seat rear passenger, where the lack of a bulky tunnel eating into legroom means adults can sit there comfortably.

There's a pull-down divider separating the back seat that's also home to two cupholders, and there are twin USB connections, as well as air vents (though no temp controls).

There's no spare tyre, though, which means fiddling with the repair kit should you get puncture, or waiting for roadside assist.

Okay, first things first – what the hell is XPeng? It's been around for about 10 years in China, but only made its way to Australia last year. It was founded by some former car company execs and tech tycoons — one of whom is telecommunications billionaire He Xiaopeng, which is where that name comes from.

Anyway, this one is the XPeng G6, which launched in Australia with two trims – the Standard Range, which is $54,800, before on-road costs, and the one we’ve tested, the Long Range, which is $59,800. The difference is in the battery size, of course, but we’ll get to that in a minute. 

As of now, the new Model Y can be ordered for $63,400 for the Standard Range or $73,400 for the Long Range, which makes the XPeng a whole heap cheaper.

Outside, you get LED lighting all around (including the DRLs), a massive glass roof, auto door handles, an auto-opening boot, a V2L connection, which allows you to use your XPeng’s battery to power whatever you plug in and big 20-inch wheels wrapped in Michelin rubber.

You also get some cool high-tech features, accessed through the XPeng app, like the ability to drive your car out of tight parking spots remotely.

Inside, there are synthetic-leather seats that are heated, a heated steering wheel, dual-zone climate, a massive 18-speaker sound system (with speakers in the headrest), wireless charging and two very handy screens — a responsive 15-inch central screen with Android Auto and Apple CarPlay, and a 10.2-inch digital dashboard.

There’s also more safety stuff than you can shake a crash test at, but we’ll come back to that in a second.

Under the bonnet of the 630i is a 2.0-litre four-cylinder turbocharged petrol engine, which produces 190kW of power (at 6500rpm) and 400Nm of torque (from 1550-4400rpm). It uses an eight-speed automatic transmission, and is rear-wheel drive.

That may not seem a lot considering the size of this machine, but consider that some of the steamiest four-cylinder hot hatches have nearly the same outputs, and you realise this engine offers up a far-from slouched approach to propulsion.

The 640i xDrive has a 3.0-litre six-cylinder turbocharged engine with 250kW of power and 450Nm of torque. It gets the same eight-speed auto, but as the xDrive naming indicates, it's all-wheel drive.

But this is the one you'd prefer if you want to hit highway speed in a hurry - the 0-100km/h claim is 5.3 seconds, where the 630i takes a full second longer (6.3sec) according to the company.

This G6 is a rear-wheel drive affair, with a single electric motor housed at the rear axle. It produces 190kW and 440Nm in Standard Range form or 210kW/440Nm in Long Range guise, which don’t sound like massive numbers — especially given the 2.0-tonne-plus weight of this XPeng – but it gets up and moving just fine.

The 100km/h sprint is a claimed 6.2 seconds, while the top speed is 200km/h.

BMW claims fuel use of 7.0 litres per 100 kilometres, and you'll need to use 95RON premium unleaded when you fill up.

On my trip with the car, I saw about 9.0L/100km across mostly high-speed driving - some freeway, some highway, some country back road touring, and quite a bit of corners and city stuff thrown in as well. I think that's pretty respectable.

What wasn't so great was the lack of premium fuel in some of the 'away from civilisation' places on my route home. Keep that in mind if planning your own GT long-distance cruise.

The Long Range version of the G6 nabs a 87.5kWh battery (compared to 66kWh in the Standard Range), unlocking a claimed driving range of 570km. 

The official power use figure is 17.5kWh/100km, but I did a fair bit of driving on all sorts of roads and my number was more like 14kWh.

When it does come time to charge, the G6 is set up for 280kW DC fast charging which means, should you find the right fast charger, a 10-80 per cent charge should arrive in just 20 minutes. Home charging will take a lot longer, of course – we’re talking overnight plugged into a regular wallbox.

I'll put this out there - if you like to drive, there are BMW models for less than this one that will put a much bigger smile on your face. Like, a 440i Gran Coupe, or even just a 330i sedan…

But if you're in BMW's target market - that being older executive buyers who want space and luxury as a priority over thrills at the wheel, you could do a lot worse.

That's because the 6 Series GT lopes along the highway without fuss - the engine easily coping with the demands of overtaking moves, the adjustable drive modes allowing a light steering and wafting suspension feel to wile away the kilometres.

There are 'Comfort' and 'Comfort Plus' modes, but the latter is a bit too spongy and can be boaty feeling. The Comfort setting is made for the highway.

It is actually pretty agile for its dimensions.

If you decide to deviate from the straight sections, you'll be able to explore a little bit of dynamic range, especially when you dial up the 'Sport' mode, which changes the damper settings, steering weight, throttle and transmission response, and even the digital dials in front of the driver to a more aggressive look.

Our car had the 'Integral Active Steering' setting, which is a variable ratio steering system that includes rear steering - that essentially helps make is more turnable in corners at highway speed, and easier to park at lower speeds. It's difficult to say whether the assistance is excellent or not short of driving a car without the tech, but to this tester it was hard to hide the size and weight (1835kg kerb weight) of the vehicle.

That isn't to say it's clumsy or lumbering - it is actually pretty agile for its dimensions, though it makes a lot more sense on long drives and coastal cruises than it does in the narrow and twisty alpine roads of the Snowy Mountains Highway that I tested it on.

There's good grip from the tyres, and strong response from the powertrain - but if it were my money, and I had to have a 6 Series for whatever reason, I'd be looking towards the 640i model, which has a thumping six-cylinder with 250kW/450Nm - certainly an engine that would be more at home in this car. Plus that model comes with AWD.

How much you love your time behind the wheel of the XPeng G6 comes down to what you're looking for from your mid-size electric SUV.

Speed and sportiness? There's not much of either. But it does serve up tons of space and technology, surprising refinement and a calm and cosseting ride.

And I think you can mount a pretty solid argument that all of that is pretty important in a mid-size SUV, more so than the ability to carve corners.

I did some solid driving in the G6, including a round trip from Sydney to the start of the NSW South Coast, taking in every road type and surface imaginable, and XPeng proved super comfy, pretty quiet and very, very easy the entire time.

Sure, it's not one of those EVs that makes the scenery blur when you put your foot down. Its outputs and acceleration are a bit more user-friendly than that. But it also doesn't ever feel underpowered, with the plenty of poke away from the lights and even some in reserve for freeway overtakes at 110km/h.

The steering, even in its 'Dynamic' mode, is fairly soft, and you can never magic away the weight of the XPeng in corners, where that compliant suspension does allow for some roll, but it also doesn't feel entirely disconnected from the road below in that disconcerting way some vehicles can.

So, if comfort is mission critical in your SUV space, the XPeng delivers.

Oh, and I know that big screens aren't that uncommon these days, but the multimedia unit in the XPeng is a treat. It's super fast, even when scrolling across maps, and it's relatively user friendly, too.

The XPeng G6 wears a maximum five-star ANCAP safety rating from assessment in 2024, owing mostly to a flood of active safety features that arrive as standard, including AEB (with pedestrian, backover, cyclist, motorcycle and crossing detection), lane departure warning, lane keep assist, speed sign recognition, driver monitoring and more.

But it could also lay claim to a unique record – the first Chinese EV in which the safety systems don't make you want to make you pull your hair out with their incessant chiming and bonging.

Only on the freeway, where an intermittent chiming incorrectly warned me I was leaving my lane, were the safety systems at all overzealous. Otherwise, they were entirely liveable.

If a crash is unavoidable, the airbag count runs to seven (dual front, front side, side curtain and front centre) and multi-collision brake is standard, to minimise the chances of a secondary crash following an initial impact.

BMW runs a condition-based servicing plan, which means the car will tell you when it needs servicing. But you can rest assured it won't (theoretically) cost you much, with the brand's 'Service Inclusive' pack. It covers you for basic maintenance as and when required for five years/80,000km. According to BMW, that includes "annual vehicle checks, oil changes, all filters, spark plugs and labour costs for the duration of the package".

BMW offers a three-year/unlimited kilometre warranty plan, and you get the same cover for roadside assistance.

I'm scoring the regular warranty offering here, which is five years or 120,000km, with the battery covered for eight years or 160,000km. Keep an eye out for deals, though. At the time of writing XPeng was offering a 10-year warranty on both, for example.

Service intervals are 12 months or 20,000km. The cheapest individual service is $238, but over five years the total cost is $2064, averaging out to more like $410 per year.
