X6 and 7-series hybrids have been launched at Frankfurt

BMW has launched its first hybrid models at the Frankfurt motor show — and one of them will be the world’s most powerful hybrid.

Badged ActiveHybrid X6 and ActiveHybrid 7, the two cars use V8 petrol engines, but the X6 features two electric motors while the 7-series has one.

The X6’s drivetrain will produce a combined 478bhp and 575lb ft, which makes it the most powerful hybrid in the world, according to BMW.

That’s enough to enable the car to reach 62mph in 5.6sec, just 0.2sec slower than the xDrive50i. BMW also claims combined fuel consumption of 28.5mpg, with CO2 emissions of 231g/km. The car can also run on electric power only at up to 37mph for 1.6 miles.

BMW has attempted to differentiate the ActiveHybrid X6 from a regular X6 with the addition of what it calls a powerdome on the bonnet — a bulge in the sheetmetal — and it comes in a new metallic blue available only on this model.

However, all this additional technology means the ActiveHybrid X6 weighs in at 2450kg, making it 185kg heavier than a standard V8 X6. Its maximum permissible vehicle weight is 3100kg.

The 7-series is less powerful, with 459bhp and 561lb ft, but faster, cleaner and more fuel efficient. It hits 62mph in 4.9sec, returns 29.1mpg and emits 219g/km of CO2. It’s not a full hybrid, though, and can’t run on the electric motor alone; it’s just a back-up for the V8.

The electric motor and its ancillaries are similar to those used in the Mercedes S400 hybrid — BMW and Daimler co-developed the tech — and it uses lithium ion batteries.

Like the S400, neither BMW will be available in the UK, due to the cost of re-engineering for right-hand drive and the limited appeal of vehicles with large petrol engines here. “Eighty-five per cent of X6s and 90 per cent of 7-series sold in the UK are diesel-powered,” said a BMW source. “And both hybrids are petrol-based, so they’re a niche within a niche.”

Hmm I think this is about performance. Maybe this line is a clue:

"The car can also run on electric power only at up to 37mph for 1.6 miles. "

Marketing schpiel. The 740d that Autocar drove emits 181g/km. Good effort, but maybe the 3-litre twin turbo petrol engine would've been more sensible...

can someone explain why this is please? So you do your 1.6 miles of electric powered driving... then the V8 takes over, then what?! How do you get your electric power back?

1.6 miles, seems a waste of time...

Keep it simple thanks!

"...28.5mpg, with CO2 emissions of 231g/km. The car can also run on electric power only at up to 37mph for 1.6 miles."

Way to go BMW, excellent use of hybrid tech. Why save the world when you can waste time on a niche within a niche, eh?

Still, I'm sure this will be very useful for negotiating Rue du Faubourg St. Honoré...

Good post.

This has to be close to the ultimate marketing cynicism. Most companies would be ashamed to release figures like this, never mind brag about them.

However, it will probably sell in the USA where the words "hybrid" and "sainthood" seem to have become interchangeable (people generally being not very technically aware).

While I don't necessarily agree with what BMW if offering here, I think they have strong reasons for doing this:

- BMW is still (mostly) about performance so they are never going to offer a 7-series that can't outrun a Prius
- Hybid technology is still expensive (even for Toyota who have sold their units in the millions now) so the only way BMW is likely to get some return on their investment in the short term is to make it a premium product, which for them equals performance.

I'm sure that once they have got people used to the hybrid idea and they have paid back some of the steep R&D costs, we'll see cheaper, lower performance/better efficiency hybrids from them too.

The electric performance and range is frankly pathetic.

Having said that, considering how powerful these engines are (in X6's case the drivetrain will produce a combined 478bhp and 575lb ft), the quoted mpg and CO2 emmissions are not bad at all.

[/quote] You do realise that it's a hybrid they've produced, not an EV? The Prius will only run for a similar distance on battery alone. A hybrid is about using multiple power sources for maximum efficiency or power. The range on battery alone of some hybrid trains is zero. And I agree with the observation that BMW are targeting the premium sector first. Toyota have a ten year head start on BMW so they'd be foolish to try to compete head on yet. That said, it would be interesting to see what they could do with the technology using their 3 litre petrol engine - that seems to already offer a pretty impressive balance of economy and performance.

I do realise that it's not an EV. But it stikes me as a poor effort. I admit performance is better but I just thought BMW could do better than this.

To put it in context MG Rover had something like this working in an MG F several years ago. It's really not rocket science. Surely making cars out of aluminium to save weight, increase MPG and boost performance would have been a smarter move.

COME ON PEOPLE! I really think the point of this technology is largely lost in this forum. Do people realise what BMW-MERC have achieved here? Let me repeat..

Near 500BHP V8 PETROL, ALMOST 600LB/FT TORQUE AND YET EVEN WITH 2.5 TONNES LOG ABOUT, IT'S STILL GIVING CLOSE TO 30MPG AND 230g/km CO2. The 7 - Series figures are even more captivating. Regardless of which model this technology is being showcased in, it should not detract from this simply amazing piece of engineering feat.

No one complains that a Nissan GTR with only 3.8Litres, 480BHP/430LBFT torque & 1.75tonnes releases 298g/km CO2. Imagine this engine in a lighter car and I for one feel very excited about the future of performance cars and their efficiencies. We should really celebrate this. It is after all a petrol engine and not a diesel. The 30mpg hypercar is almost upon us!
