Summary
BMW 6 Series
What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.
That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.
Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.
I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.

Mercedes-Benz C-Class
When it comes to choosing a family car, sedans are often overlooked for their long-legged wagon or beefy SUV cousins.
They're a bit of a forgotten hero but they'll always hold a piece of my heart for their practicality and (often) sexier kerb-side appeal.
If you can get used to your body cracking like a glow stick when you get in and out of them, the sedan may make a comeback!
The new Mercedes-Benz C-Class, in entry-level C200 form, has definitely tempted my family to consider a sedan in the future – it looks stately and refined but the driving experience also makes it fun.
Let's see what else it did right and if there was anything that could be improved.
Did I mention, I'm fond of sedans... ?

Verdict
BMW 6 Series7.6/10
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.
Would you consider a genre-bending car like the BMW 6 Series GT? Let us know in the comments section below.
Mercedes-Benz C-Class8/10
The Mercedes-Benz C-Class C200 is such a stylish sedan and I would totally have one. The driving performance, luxurious features and practical size made it a winning combo for my family. The price point is definitely up there but you do get a high-end build for the cash. I've seen bigger boots in other sedans and not being able to fit a third child seat will limit some families, but this still easily earns an 8.5/10 from me.
My son really loved this one. The ambient lighting was the highlight for him and he thought it looked like a "space car" inside. He gave it a 9/10.
Design
BMW 6 Series7/10
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.
Mercedes-Benz C-Class
The C200 is a sleek and elegant steed.
Initially, you may think this is just a standard Merc showcase. There's the nice big badge on the pronounced nose. Beautiful sleek lines in the body... but it's the attention to detail that make this feel special.
There's a repeated badge motif in the grille and a cute cursive Mercedes logo tucked into the corner of the windscreen. The puddle lights on the doors project the badge at night time and you can often spot a badge etched into the LED lights.
However, it's the interior that's the highlight for me and I feel like it's a big step up from previous models I've been in.
Our model has the grey 'Artico' synthetic leather trim (says grey but it's really white) and a lovely mix of piano black and shiny chrome inserts that are set against soft touchpoints throughout.
The quality of the build oozes through every stitch and join. Don't even get me started on the cool customisable ambient lighting system inside, which makes this feel like you're on the set of Tron and really elevates the interior.
It's quite fun to build one of these in Mercedes' online configurator. You can customise your trims to make it feel like your own and their blue paintwork options are great (I do love a blue car).
Practicality
BMW 6 Series9/10
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.
Mercedes-Benz C-Class
I'm not going to lie – there are sedans out there that have an almost limo-like space inside but the C200 isn't one of them.
It's not small by any means and all occupants enjoy the comforts of decent legroom and headroom but it's not cavernous considering the specs (1437mm high/1820mm wide/4751mm long).
The optional panoramic sunroof does cut into the headroom for back seat passengers, which is something to consider if your family is very tall.
The storage is maybe a tad leaner-than-average for a car of this size. The glove box and middle console aren't massive but will suffice.
The cupholders up front can be removed if you need extra storage space for larger items and back seat passengers enjoy retractable cupholders in the armrest.
The way the front doors curve out creates a larger than normal storage bin and drink bottle holder – which help make up the difference. There is a dedicated phone pocket, to tuck it out of the way.
The boot space is 455 litres (VDA), which isn't as large as some others on the market but it was plenty big enough for my family's needs.
There's a handy under-floor storage pocket for smaller items, like the puncture repair kit, because you don't get a spare tyre in this.
When it comes to ease of use, my six-year-old loved not needing my help to get into his seat and he still enjoyed a decent view out of the wide back window.
The amenities in each row are good but not class-defining. Still, creature comforts have be well-thought through.
Front occupants enjoy heated seats and fantastic lumbar and under thigh support. Dual-zone climate control sorts out the temp, and the cool circular air vents that make loud audible 'clicks' when manoeuvred give the interior a jet cockpit vibe.
While I've never had an issue opening or closing a sedan boot, the powered lid was a nice feature to have this week.
The tech throughout is great and intuitive to use. The massive 11.9-inch touchscreen multimedia system is cool and is easy to use once you become acclimatised to Mercedes system.
The customisable digital instrument panel makes the driving experiences feel individualised.
The interior is a chilled out space with gentle scrolling touchpads taking the place of most 'push' buttons and dials.
Think of each surface as being a bit like a touchscreen tablet in how you operate it. I was a little worried the touchpads would be laggy but they're very responsive.
There's only one USB port in the whole car, which limits charging for other passengers but I did enjoy the easy connectivity of the wireless Apple CarPlay.
The electric heated front seats are a nice touch but I was amused by the 'kinetic' function on both. It's what you might call a 'massage' function on another car but here they don't really work. It's best to think of them as a way to do some (very) gentle stretching on a long trip.
The 360-degree camera view is super clear and crisp but the dynamic guidelines (which tilt the camera angle) are a bit too dynamic for my liking and I relied mostly on the bird's eye view to park.
As I've mentioned, the ambient lighting system creates a stellar atmosphere inside. I've often wondered why other car manufacturers haven't jumped on that bandwagon because it's a relatively cheap way of creating wow factor. And it generates massive wow factor in here.
Price and features
BMW 6 Series6/10
The BMW 6 Series Gran Turismo range starts off with the model tested here, the 630i. It has a list price of $123,500 before on-road costs - and that's whether you buy the M Sport Line or the Luxury Line.
That's quite a lot of money. And while it has a lot of equipment to help justify the cost, the smarter dollars will probably find their way to a more affordable 5 Series.
Standard gear in this spec includes adaptive air suspension with multiple drive modes, a colour head-up display, semi-autonomous parking, adaptive cruise control with steering assistance, auto high-beam LED headlights with LED daytime running lights, DAB+ digital radio, a 16-speaker harman/kardon sound system, a 12.3-inch driver information screen and a 10.25-inch media display with sat nav, Bluetooth and 'BMW ConnectedDrive' online services.
Hey, you even get a panoramic sunroof as standard! Plus there are things like an active rear spoiler, two USB ports and four 12-volt outlets, leather trim, heated front electric seats, electric steering wheel adjustment, keyless entry, push-button start, and an automatic boot.
It also comes loaded with active safety assistance functions - we'll get to that in the safety section below.
Things it's missing at this price point? Well, heated seats are an option, but bundled nicely into the 'Comfort Package' ($3000) which was fitted to our car. The pack includes heated seats front and rear, quad-zone climate control, electric sunblinds for the rear side windows, and electric seat back adjustment. Oh, and BMW continues to gouge consumers $623 for Apple CarPlay (which seemingly didn't work in our car).
The only other 6 Series GT model available is the 640i xDrive, which is again available with the choice of M Sport or Luxury body styling. It's also pretty exxy, with a list price of $148,900, but gets a more performance-focused drivetrain, as well as extra equipment: essentially the Comfort package, plus vented front seats, interior fragrance (eight options), memory settings for the front seats, 20-inch wheels and metallic paint.
Plus the 640i has Sport+ settings - it's probably the wrong car for those - and 'Integral Active Steering' to couple with the all-wheel drive system.
Mercedes-Benz C-Class
Herein lies the rub. There are four models for the C-Class sedan and ours is at the bottom of the pack.
But don't let its position fool you in thinking it'll be cheap because this model starts at $78,900... and that's before you start adding the option packs.Â
Our model is fitted with the 'Vision Package' which adds a host of features – like a panoramic sunroof, head-up display and heated front seats, to name just a few. This adds about $3000 to the price tag.
This also has the optional 'Sport Package' which adds 19-inch AMG alloy wheels and rear privacy glass, among other things, for an extra $1300.
Unfortunately, even without all of those options, this is still one of the most expensive 'entry-level' sedans in the luxury class!
Under the bonnet
BMW 6 Series8/10
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.
Mercedes-Benz C-Class
The C200 has a 1.5-litre, four-cylinder, turbo-petrol engine with an integrated starter-generator.Â
What's that, you ask? So, glad you did. It's basically an electric battery that also acts as your starter... or alternator.
It smooths out vibrations from the engine and generates some power from braking. Making this a very mild hybrid. Note the 'mild'.
Is it powerful? Surprisingly, yeah. It has a maximum output of 165kW and 300Nm of torque. Combine that with the starter-generator and we have a powerful little engine that can push the C200 from 0-100km in 7.3 seconds, while still feeling like there's power in reserve.
The nine-speed auto transmission is damn smooth and there's no clunky gear changing at any speed. It's got great pick-up, too, for when you need to overtake or zip across traffic.
Efficiency
BMW 6 Series7/10
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.
Mercedes-Benz C-Class
The official combined cycle fuel figure is 6.9L/100km. Real world testing saw my figure at 7.2L, which was awesome for the heavy driving I did this week on a combo of urban and open-roads.
The light regen braking probably helps this coast comfortably into being a very efficient sedan for its size.
Minimum fuel requirement is 95 RON premium unleaded and you'll need 66 litres of it to fill the tank.
Driving range using the official consumption figure is around 950km, and 915km using our real-world number.
Driving
BMW 6 Series7/10
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.
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.
Mercedes-Benz C-Class
The steering feels solid and concise. The tyres seem like they're glued to the road, making winding roads downright fun to tackle. Oh, and the sharp 11 metre turning circle is wonderful.
The handling makes this your best friend in a car park. The lower ground clearance did elicit some unladylike grunts when I parked on a hill, but otherwise the wide door apertures makes it easy to get in and out of.
The only thing I would note is the low-profile ground clearance. Just be aware of your speed and angle when you handle car park ramps or road bumps in this. They are not your friends.
Safety
BMW 6 Series9/10
The BMW 6 Series GT range has a five-star Euro NCAP crash test score based on 2017 testing, but it hasn't been scored by ANCAP.
There's the usual array of airbags - dual front, front side, full-length curtain and driver's knee airbags are included, plus parking sensors all around, and heaps of safety tech including the 'Driving Assistant Plus' package with lane departure warning and lane keeping assist, forward collision warning, auto emergency braking (AEB) front and rear, blind-spot monitoring and rear cross-traffic alert, and adaptive cruise control with stop and go.
That's all great stuff, and so is the 360-degree camera system with adaptive display - so, if you're reversing and you turn the wheel to one side, the image on screen will move, too. It'll also go between a birds-eye view and a backing-up perspective, and that can take some getting used to.
What was less convincing in terms of the user experience was the rear auto braking, which seemed to be scared of the car's own shadow. On multiple occasions the car jammed on the brakes when reversing out of driveways on to empty streets - be it in the normal height, or the raised height setting.
The 6 Series GT has dual ISOFIX anchor points and three top-tether points are there and ready for baby seats or child seats.
Mercedes-Benz C-Class
The safety sheet is well-stocked and has the usual suspects you want in a family car, like: AEB with car, pedestrian, cyclist and junction turning assist (effective speed 7.0-90km/h); forward and back-over collision warning, lane keeping assist, lane departure warning and emergency lane keeping assist, as well as, blind-spot monitoring.
I quite like the 'Active Distance Assist' which helps to automatically slow your vehicle speed to keep a set distance to the car in front in stop-start traffic.
Perfect for those busy city commutes. And if you're not confident on parking, this also has a 'Park Assist' feature.
It's nice to see that this has nine airbags, which include a driver's knee airbag and the newer front centre airbag.
This has a maximum five-star ANCAP safety rating which is nice and new from testing done in 2022.
There are ISOFIX child seat mounts on the outboard rear seats and three top tether anchor points but because of the narrower rear seat, you'll only comfortably fit two side-by-side.
It was super easy to fit my seats and there's a good amount of room for front passengers when a 0-4 rearward facing child seat is installed.
Ownership
BMW 6 Series8/10
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.
Mercedes-Benz C-Class
The C200 comes with a five-year/unlimited km warranty, which is standard for the market.
There are multiple servicing options and on the five-year plan, the services average $1090 annually, which is quite expensive.
Servicing intervals are pretty good at every 12 months or a longer than usual 25,000km, whichever comes first.
