BMW 6 Series vs Hyundai Genesis

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 Genesis is not quite a match for cars twice its price but it makes you think what's possible. It doesn't have the dynamic brilliance of a BMW or the self-assured faultless execution of a Mercedes. Lexus ought to be worried, though - why would you have an LS when you could have this? The only answer is 'badge'.

The Genesis is an epoch-making car for the Korean manufacturer. As the company has got better, there are fewer excuses for overlooking it. While the Genesis is pitched into a shrinking market, it's not really meant for the average i30 buyer to buy, but to see.

It's bristling with tech and is not only a halo car but a shot across the bows of both Lexus and the Germans. Attached to that shot is a note: "We're coming for you." In other words, Hyundai got it right.

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 Genesis is like no other Hyundai. For a start, it's gigantic - it looks easily as big as a BMW 7 Series (it isn't) with the road presence to match. There's a lot of BMW from most directions, but with a sharper approach to the creasing and character of the sheet metal.

Towards the rear it's more BMW 6 Series Gran Coupe and is all the better for it. The style is understated and technocratic.

Inside is also very Germanic, but with a bit more of a Lexus feel

The big wheels from the Ultimate pack help make it look lower and sleeker, too.

Inside is also very Germanic, but with a bit more of a Lexus feel. Our car had the lighter leather which meant that the wood and the metal materials didn't necessarily work well together.

The interior is expertly put together and feels like it will last forever.

The only jarring moment is the gear selector is shared with our long-term Hyundai i30 - it looked a bit cheap in what is otherwise a beautifully executed cabin - it needs more heft.

On Australian-delivered cars there is just one Hyundai badge, sitting proudly on the boot - you get the feeling this was debated long and hard and when the decision was made to go for it, a big one was chosen.

However, the winged Genesis branding takes pride of place everywhere else. When you approach the car at night and the puddle lamps come on, the Genesis logo is projected on to the ground, crisp and clear.

The only way to describe the Genesis' pricing is aggressive - kicking off at $60,000, it's the most expensive Hyundai money can buy, but with a spec list like this, you won't feel at all short-changed.

Your sixty large buys you a huge cabin with a seventeen speaker stereo, auto headlights and wipers, LED ambient lighting inside and out, dual-zone climate control, keyless entry and start, powered front seats which are heated and cooled, satnav, front and rear parking sensors, and plenty of other bits and pieces.

Our car had the $22,000 Ultimate package, adding 19-inch alloys, blind spot sensor, front and side cameras, around-view display, real leather, more adjustments for the driver's seat, ventilated seats in the front, heated rear seats, panoramic glass sunroof, acoustic glass, heads-up display, powered bootlid and LED foglamps.

The Genesis is like no other Hyundai

You can have a lot of the more useful features in the $11,000 Sensory Pack. It's a good middle ground that, for example, features the excellent heads-up display.

The 9.2-inch screen splits the asymmetric air-conditioning vents. The software is unique to the Genesis and a huge leap forward over the rest of the Hyundai range - classy, smooth graphics, a good responsive screen.

You control the seventeen speaker stereo from here, which kicks out a rich sound and an impressive Bluetooth performance - rear seat passengers can also run the stereo from their armrest. The satnav is detailed and chatty, while the excellent heads-up display shows a configurable information set in strong, clear graphics.

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 Genesis is powered by Hyundai's own 3.8-litre V6 developing 232kW and 397Nm, mated to Hyundai's eight-speed automatic transmission.

Despite weighing just under two tonnes, the Genesis completes the dash to 100km/h in 6.5 seconds.

It has a claimed 11.2L/100km on the combined cycle. In what must be a first, we got below that, averaging 10.8L/100km over two weeks. And that's without stop-start fuel-saving to blunt the effect of lot of city driving.

The Genesis is not going to tempt you into a track day, even with rear wheel drive

We'd still like to try the V8 - only available in left-hand drive markets - though.

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.

At five metres long, with a ride firmly pitched in the luxury camp, the Genesis is not going to tempt you into a track day, even with rear wheel drive.

Blindfold your passengers and swap them between a Lexus, a BMW and a Genesis and the overwhelming impression they'll get is one of incredible smoothness.

If you're wanting sudden movements, this isn't the car for you

Sitting in the back of the Genesis, it's easily as good as the German and luxury Japanese competition. The seats are hugely comfortable, there's ample head, leg and shoulder room and it feels lot nicer than anything within a bull's roar of its price.

No matter where you sit, it's an incredibly quiet car. The engine is a distant whoosh, the tyre noise muted and there's almost no wind or ambient noise. It's supremely comfortable and the excellent stereo will wash away what little noise does invade.

It certainly feels its weight from the driver's seat, with a competent, soft turn-in, but if you're wanting sudden movements, this isn't the car for you.

The Genesis is an epoch-making car for the Korean manufacturer

On fast flowing roads you can have some fun, but things will get floaty and that will quickly kill that fun. The ride and isolation from the rest of the world is completely worth it.

Nine airbags, traction and stability control, lane departure warning, forward collision control, ABS, brake force assist and distribution and traction and stability control bring the ANCAP count to five stars.

The Sensory and Ultimate packs add blind spot sensors and around view cameras.
