BMW 630I vs Genesis G70

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 updated Genesis G70 3.3T Sport Luxury is beautiful to look at and drive. It features premium features, trims and great power but the cabin is tight on space. Which makes it a little awkward to use, so this will suit a small family best or families where this may not be the primary mover. That said, I love the after-care program and it suited my small family of three, so it gets an 8.0/10 from us. 

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.

The G70 sedan is absolutely gorgeous to look at and the our test vehicle's 'Kawah Blue' paintwork makes the crisp pleating across the body stand out.

The G70 has a muscular stance, much like its BMW rival, but the rear is softer in its shaping.

The front looks sophisticated with the wide-set LED lights and black air-intake vents. The sporty 19-inch alloy wheels and red calipers behind them hint at what the powerful V6 engine can do.

The interior looks high-end with our test vehicle’s white quilted Nappa leather upholstery and a soft-touch black headliner. The dashboard looks solid and robust but the slick looking 10.25-inch touchscreen multimedia system and digital climate control panel elevate the overall design. 

The only thing I didn’t like about the design was the ambient lighting. It’s limited to two panels on the roof and is a little distracting when you drive at night. I think if it was scattered more throughout the cabin, it would be less intrusive.

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 practicality is hurt a little by the space available for passengers. The front row benefits the most when it comes to head- and legroom but if you’re ferrying passengers in the back seat, you’ll have to scoot your seat forward to accommodate them.

Especially if they’re tall because my knees brush the back of the driver’s seat when it’s in my driving position and I’m only 168cm tall!

The individual storage options throughout the car are okay for the class with the front enjoying a small middle console and glove box, two cupholders and two small drink bottle holders in each door.

The rear gets map pockets, two cupholders in a fold down armrest and two very small storage bins in the doors.

The other amenities are great in both rows and a high-level of comfort will be found for adults with the heat and ventilation functions on the front seats and the heat function on the rear outboard seats.

However, the width of the rear seat and the tall transmission tunnel means the middle seat should be strictly reserved for a kid. Think of the G70 as more of a four-seater if you have adults to carry.

The boot has a 330-litre capacity and it’s not too hard to reach to the very back if items roll that way. The back seat has a 60/40 split and there is a temporary spare tyre underneath the floor. 

In terms of technology, you get a USB-A and USB-C port up front, as well as, a 12-volt socket and wireless charging pad to choose from. Rear passengers get two USB-C ports and the boot features another 12-volt outlet.

The 10.25-inch multimedia system looks great and is easy to use with a responsive touchscreen. It also has built-in satellite navigation, wired Apple CarPlay and Android Auto and the system now features over-the-air updates and Genesis Connected Services functionality.

The digital climate panel is responsive and very simple to operate, which is handy when on the go. The 12.3-inch digital instrument cluster is semi-customisable and it’s handy that the 8.0-inch coloured head-up display pulls through satellite navigation directions and traffic sign information. 

The G70 3.3T Sport Luxury sedan on test here is priced at $88,000, before on-road costs, which is $7000 more expensive than the 2.0T Shooting Brake version. That positions it right in the middle of its nearest competitors and you get some fab features included. 

The premium items include electric front seats with heat and ventilation functions, heated rear outboard seats, Nappa leather upholstery and other leather trims, a sunroof, a heated leather-wrapped steering wheel and a premium 17-speaker Lexicon by Harman sound system.

The update sees the G70 now have an intelligent speed limit assist feature, the 'Genesis Connected Services' app and over the air updates to its software.

Other standard features include keyless entry, keyless start, remote start from the key fob, a powered tailgate, 19-inch alloy wheels, a temporary spare wheel, dual-zone climate control and extendable sun visors.

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 G70 3.3T Sport Luxury sedan has a 3.3-litre V6 turbo-petrol engine with a maximum power output of 274kW and 510Nm of torque. The G70 sedan is a rear-wheel drive and features an eight-speed auto transmission.  

The V6 engine responds eagerly, being able to do a 0-100km/h sprint time in just 4.7-seconds. Suffice it to say it’s fun to drive.

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 compromise for getting all of the power is that she’s a thirsty gal and the official combined cycle fuel consumption figure is 10.4L/100km and my real-world usage came to 10.6L/100km.

However, that’s after mostly doing open-roading – expect the fuel usage to be higher in an urban setting.

Based on the combined cycle and the 60L fuel tank, expect a driving range of around 577km on average. Which means you’ll be filling up more on a longer journey than more efficient sedans.

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.

The G70 sedan is a lovely car to drive with graceful handling and a good well of power to dip into.

That oomph is there when you need it and it’s as easy to drive in the city as it is on the open-road.

The responsive steering makes the G70 sedan feel nimble and well-balanced in turns, even when you accelerate out of a hair-pin corner.

The suspension is on the firm side and that can lead to a few grunts when you hit bigger bumps but the ride is not unpleasant, even for back-seaters. 

The cabin is generally quiet but you can get road/wind noise at higher speeds. It’s not enough to intrude on chatting but you don’t forget it’s there, either.

The G70 sedan is easy to park because it has an outstanding 11m turning circle. The 360-degree camera system is clear and the front and rear parking sensors make light work of a tight car park.

The Genesis G70 has a great suite of safety features and it’s almost a case of what doesn’t it have.

But a real highlight is the blind-spot view monitor which pops a video feed of your blind spot onto your instrument cluster. Very handy to have in a city setting!

The G70 has a maximum five-star ANCAP safety rating from testing done in 2018, with the update now featuring 10 airbags, which is fantastic for the class.

Other standard safety features include blind-spot monitoring, blind-spot collision avoidance assist, driver attention warning, forward collision warning, lane keeping aid, lane departure alert, rear cross-traffic alert, rear occupant alert, adaptive cruise control with stop and go function and a tyre pressure monitoring system.  

A clear 360-degree camera system as well as front and rear parking sensors also come standard.

The G70 has AEB (operational from 10–180km/h) with pedestrian and cyclist detection.

There are ISOFIX child seat mounts on the rear outboard seats and three top tether anchor points but only two child seats will fit. Front passenger comfort may be compromised for front occupants 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 Genesis after-purchase program is hard to beat and such a treat because you get five years or up to 50,000km complimentary servicing with the G70. How good is that? 

The G70 also comes with a five-year/unlimited km warranty and the servicing intervals are every at 12-months or 10,000km, whichever occurs first. The interval could be annoying if you travel a lot but any annoyance will be softened by the fact that the services are free.
