BMW 7-Series ActiveHybrid - Hybrid style - 2008
Tsk. It’s always the way, isn’t it? You wait ages for a
hybrid rival to the Lexus LS600h to turn up, and…
Yes, hot on the heels of the Merc S400 BlueHybrid comes
this, the BMW 7-Series ActiveHybrid.
Also set to be launched in Paris next week before reaching
our roads next year, the ActiveHybrid is BMW’s first genuine, er, hybrid.
Although still currently billed as a concept, it’s powered
by BMW’s twin-turbo 4.4-litre V8 petrol engine mated to an electric motor
that’ll add some 20bhp to the combustion engine’s 407bhp.
Like the Merc, the two can combine to give a proper kick of
low-end torque - as much as 597lb ft, in this case - and improve consumption by
up to 15 per cent.
As the 750i on which the ActiveHybrid is based manages 25mpg
on the combined cycle, we’d imagine that means economy of around 29mpg - hardly
revolutionary, but still impressive for a big V8 saloon.
The ActiveHybrid will, as expected, get BMW’s stop-start
technology already seen on Mini diesels, and lithium ion batteries, which are
far more compact and efficient than traditional lead acid units.
Still left a touch cold? Well, what about this: we’re told
that this very drivetrain could find its way into the upcoming ‘baby Rolls’
It’s not quite what we were promised hybrids would be like
in the future though is it?
