BMW 6 Series vs Mazda CX-60

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.

The Mazda CX-60 GT P50e will suit those families that don’t need the extra seats of its bigger siblings but still want some luxury and comfort. I like the features and the hybrid efficiency but don't like how it handles in the city. I got used to it but it’s not my favourite plug-in hybrid to drive and for the higher price tag, I did expect a smoother experience.

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.

For me, Mazda SUVs are a bit too similar to get me excited. It’s a case of ‘same same but different’ when they’re on the road.

Each one looks like a scaled version of the other but the GT’s body colour extends to the lower cladding and wheel arches, which makes it appear larger than the CX-5 at least.

The GT model is also set apart from the base Evolve model with the heavier use of black accents – like the gloss black side mirrors, 20-inch alloy wheels and honeycomb grille. It’s 'PHEV' and 'In-line 6' side badges are also blacked out for added sportiness.

Full LED exterior lights in Mazda’s classic slim-line look plus some added ‘in-take’ vents at the front complete the overall package.

In the cabin, there’s a strangely wide panel on the dashboard that separates the centre console from the media system and it doesn’t look right compared to the skinny air-vents and button panel that sits below it.

The interior does sport black leather-accented trims and enough soft touchpoints that there is a sense of quality throughout but I was hoping for a more luxuriously-appointed interior, given the price tag. Especially considering the top-spec CX-5 model is a good $25K more affordable.

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.

The cabin is practical with its great sense of space in both rows, which is not always the case for a mid-sized SUV. Taller families will love how much legroom there is to be had.

The front passenger can get comfortable with the eight-way power adjustments on their seat but the driver enjoys the most perks with 10-way adjustments, lumbar support and two-position memory function.

Both seats have heat function (up to three levels) and are well-cushioned for a longer trip.

The rear seats are well-padded and feature a handy 40/20/40 split-fold for internal storage. The outboard seats also have a heat function for added comfort.

My six-year old found this car to be super easy to get in and out of because of the 175mm ground clearance. He also enjoyed a good view from the wide windows and liked the amenities, like the directional air vents and reading lights.

Individual storage is decent in both rows but the front passengers get the best options with two cupholders, extra-large storage bins in each door, a glove box and a middle console, which is on the shallow side.

Back seaters get two cupholders in the fold-down armrest, small storage bins in each door and a couple of map pockets.

The technology looks upmarket with the dashboard being headlined by two separate 12.3-inch digital screens.

The multimedia system is easy enough to use but I wish Mazda enabled touchscreen access on this as it’s a pain to use the rotary selector dial while on the go.

That said, it’s fab that you get wireless Apple CarPlay and wired Android Auto, plus built-in satellite navigation.

The premium Bose sound system with its 12 speakers makes for a concert-like experience and the charging options are good throughout the car.

Up front you get two of the faster USB-C ports, a 12-volt socket and a wireless charging pad to choose from.

In the back seat you get another two USB-C ports plus a handy 220-volt (150W) port for bigger items. In the boot you get another 220-volt port but this one has 1500W capacity, so larger appliances can be hooked up.

The boot rounds out the cabin practicality with a decent 477L of capacity but you can bump it to 1726L if you fold down the rear seats. There are manual levers in the boot to do this.

The level load space makes it easy to slide things in and out and I always enjoy having a powered tailgate. A flipside to all of this room though is that you only get a tyre puncture repair kit rather than a physical spare.

There are three models for the CX-60 and ours is the mid-spec model, which will cost you $80,300, before on-road costs.

You get a decent number of features in this grade, so it feels well-positioned against its rivals.

The Lexus NX350h F Sport Hybrid AWD beats it by a smidge at $80,500 (MSRP) and the Volvo XC60 Recharge Plus sits well above at $92,990 (MSRP).

As you’d expect there are some luxury items to be found, like the panoramic sunroof, heated front seats, heated leather steering wheel, and heated rear outboard seats.

You also enjoy the following as standard - dual-zone climate control, electric front seats, leather-accented trim, electric steering wheel adjustment, satellite navigation, keyless entry, a hands-free powered tailgate and a 360-degree view camera system plus a bunch of upmarket technology which we’ll touch on later. 

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.

The GT P50e has a 2.5-litre, four-cylinder petrol plug-in hybrid powertrain with a maximum power output of 241kW and 500Nm of torque.

This is an all-wheel drive and has an eight-speed auto transmission.

Overall, it’s fairly gutsy and you’ll be pleased with that power when you hit the open road.

On the electric motor side of things, this also has a lithium-ion battery with a relatively small 17.8kWh capacity which gives you a driving range of up to 76km when in pure EV mode. 

It has a Type 2 AC charging port but it can’t be hooked onto a fast charger as it lacks the CCS DC connector.

On a 7.0kW system you should be able to get from 20 to 80 per cent in as little as 90 minutes. The household plug charging time is more like seven or eight hours, so best to leave overnight when at home.

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 official combined cycle fuel figure is 2.1L/100km but after an almost 600km roadie and charging it twice, my real-world usage came to 6.4L.

That's a good result considering this car's power and size but you will get the best efficiency if you charge the battery regularly. 

Based on my usage and the 50L tank, I’d be able to get a rough driving range of 781km.

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.

Well .. let’s unpack that shall we? Yes, this thing certainly has power but the biggest surprise for me was how the electric motor and combustion engine talk to one another because it doesn’t make for the smoothest driving experience in the city.

Therein lies the rub, for me. At this price point I was hoping for a smoother drive experience. In fact, it performs in the strangest of ways - when you’re accelerating, it feels like you’re in a much lower gear than you ought to be.

Almost like you’re stuck in 4WD. There is a sensation of the engine being held back and fighting you when you drive this in built up areas.

The ride comfort in the city was affected by this because it has a tendency to bunny hop/lurch when you hit corners at lower speeds. However, it has beautiful manners on the open road and that is where this model shines for comfort and handling. 

In this environment the steering feels concise and you can handle winding roads at speed without much roll. It can get a little noisy in the cabin as the electric motor wheezes a lot but otherwise, it’s alright for highway driving.

Overall, it's pretty good to park and I like the tight 10.8m turning circle. The 360-degree camera system is clear, too, but coupled with the front and rear parking sensors, you won’t have any issues.

The CX-60 has a lot of safety features I like to see on a family car and a highlight is the intelligent blind-spot monitoring system which shows the vehicles around you in a dynamic display on the instrument panel.

Other standard safety features include LED daytime running lights, lane departure alert, lane keeping aids, rear cross-traffic alert, forward collision warning, intelligent seat belt reminders, a driver fatigue monitor, front and rear parking sensors and a 360-degree view camera system.

It also has adaptive cruise control but it was a bit hit or miss. It’s quite sensitive and sometimes registers a larger vehicle, like a truck, as still being in your lane despite overtaking.

It has autonomous emergency braking with car, pedestrian, cyclist and junction assist detection that’s operational from 10–80km/h (although the car detection is operational from 4.0–160km/h).

I’m happy to say this system works well – a ‘roo jumped out in front of me this week and the car performed an emergency stop with plenty of room to spare.

It achieved a maximum five-star ANCAP safety rating from testing done in 2022 and it has eight airbags, including a driver’s knee- and a front centre airbag.

There are ISOFIX child seat mounts on the outboard seats and three top tethers and while two seats will fit best, you might get lucky with three skinny booster seats. There’s also plenty of room when a 0-4 rearward facing child seat is installed.

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.

The ongoing costs are pretty reasonable. It comes with a five-year/unlimited km warranty which is usual for the class. It also has capped-price servicing for five-years or up to 75,000km, whichever occurs first.

Services cost an average of $518, which is a little expensive for this class but servicing intervals are fine at every 12 months or 15,000km, whichever occurs first.
