New 4x4 coupe gets new 407bhp twin-turbo V8; on sale Spring 2008
15 December 2007

These are the first official pictures of BMW’s production version of the vanguard X6 four-wheel drive coupe.

The X6 will be the firm's first model to receive a new twin-turbocharged 4.4-litre V8 petrol engine when it goes on sale late next spring. The 90-degree unit, which will power a number of new performance-orientated BMW models in the next 12 months, is billed as a replacement for the company’s existing, normally aspirated 4.8-litre V8, in a move that underlines a commitment toward engine downsizing from Munich, through a combination of twin stage turbocharging and direct injection.

BMW's new firebrand 4x4: X6 xDrive50i

 

Producing 407bhp at 5500rpm along with a prodigious 443lb ft of torque between 1750rpm and 4500rpm, the blown V8 starring in BMW's range-topping X6 delivers a creditable 40bhp and 81lb ft more than BMW’s naturally aspirated V8.That’s enough to launch the range-topping X6, the 2190kg xDrive50i model, from zero to 62mph in just 5.4sec – better than a 650i automatic. Fuel consumption is a claimed 22.6mpg.

Design and dimensions

Based on the X5’s platform, the X6 shares its wheelbase but it’s longer, by 23mm at 4877mm, and wider, by 50mm at 1983mm. The sloping roof and a lower ride height make it 86mm lower than the X5, at 1690mm.

Despite the X6’s large frontal area and obvious bulk, BMW claims a drag co-efficient of 0.33 – better than a Smart Fortwo - thanks to tricks such as flaps behind the grille that only open when the engine requires additional cooling.

Inside, the X6's cabin and trim design draws heavily on that of the X5. Front seat height is put at 944mm, with individual rear seats for two passengers. Boot capacity is a nominal 570-litres – 70-litres less than the X5 - rising to 1450mm with the split fold rear seat lowered.

Target: best-handling 4x4 on the road

 

The X6 aims to dislodge the Porsche Cayenne as the best-handling SUV. Building on the X5’s accomplished chassis, it comes with BMW’s new torque vectoring unit that allows drive to be varied between the front and rear axles dependent upon traction, and between the left and right wheels for greater agility, improved traction and less steering effort.

Other improvements on the X5 include a 56mm wider rear track for added stability. Six-cylinder models come as standard with steel springs, with the more upmarket V8 riding on air springs.

The rest of the range

Along with the new twin-turbo V8, the X6 will also be offered with Munich's twin-turbo six-cylinder petrol engine – the 3.0-litre with 306bhp/295lb ft - in the £42,925 xDrive35i.

The majority of British sales will come from a pair of 3.0-litre common rail diesels; the twin-turbo 286bhp/428lb ft xDrive35d at £44,135, and the £41,995 235bhp xDrive30d.

The car industry shoots itself in the foot again. BMW does what is expected however.

Over 2000kg's of pointless metal that says everything you need to know about BMW, their target customers and this magazine which SHAMELESSLY saves BMW the cost of printing paper to promote the car.

If you thought the school run was hard now - wait for this monstrosity to appear outside little Tarquin's prep school.

It will sell - it will sell to those who know the cost of everything but the VALUE of nothing.

Autocar telling us that BMW is signalling a commitment to downsizing engines by knocking 400cc off the engine has left me completely gobsmacked. The sychophantic witterings of the 'journo' who wrote this piece leaves me in no doubt that the bias towards BMW in this mag is alive and well and completely out of kilter with the rest of the unbiased world. I can't believe that this person actually wrote that - it's hilarious.

Well yeah it is just a descriptive news story as opposed to an analytical road test or subjective column, so presumably there's only so many ways to cut and paste the BMW press pack?

"Despite the X6’s large frontal area and obvious bulk, BMW claims a drag co-efficient of 0.33"

This sentence shows a complete lack of understanding of the term drag coefficient. It is a dimensionless unit. A cube face flat to the wind ALWAYS has a drag coefficient of 1. what drag coefficient is is the ratio of drag of the object to the drag of a cube with equivalent frontal area. So just to recap: no, the X6's large frontal area does not make the acheivement of 0.33 Cd more impressive (or less impressive for that matter), it is completely irrelevant - a house brick could well have a higher Cd than a house!

Sorry for being so anal but I find it ever so distressing when I read stuff like this in such a fine publication. Please oh please, if only for the sake of my fragile disposition, can the autocar journo's have some sort of "Wikipedia Wednesday Detention" for occasions like this?!

[quote Kee Law]

it looks pretty cool, much as expected really, a coupe like X5.

as a coupe BMW seem very keen to ensure that only 2 people can sit at the back. the 3 series coupe does the same. seems to be a silly invention and needlessly ruins practicality.

oh, and anyone else find the wheels on the X6 in the video too small? need more bling!

(p.s. i'm currently watching cribs on mtv. mr plum, suggest that you never watch this show for I would fear your blood pressure would explode)

Hi Kee Law,

I am familiar with this genre of show.

Take one uneducated trailer trash type of individual, add a multi million dollar recording/sporting contract, mix together and watch the consequences of money mixed with little or no education, manners, upbringing and dare I say it, class.

Hang on - that sounds like the county of Cheshire.

I enjoy the show actually - there is nothing funnier than having all the gear but no idea.

What you talkin bout Willis?

The County of Cheshire indeed, although I think I know what you mean.

A completely pointless car, for completely pointless people.

Trust BMW to come up with something like this, problem is due to that badge it will sell. Had it got a Hyundai/Kia or similar badge, it would be shunned.

Spot on Jon.

I suspect the car park at John Lewis in Cheadle will be full of these and Fiat 500's.

Nasty, nasty and nasty.

[quote Kee Law]I think the success of motors like the Nissan Qashqai[/quote]

They keep telling us the Qashqai is a success, but where are they? I just don't see them around. Now I see plenty of X3's and X5's.

I agree with everything else you say though!

It's nice when we can all get along.
