Ferrari HY-KERS news - Geneva show: Ferrari HY-KERS - 2010
One horsepower per kilo is the Ferrari
hybrid rule. This 599 HY-KERS hybrid
has the rule applied. In other
words, whatever any hybrid system costs in weight is offset by a corresponding
power upgrade. Whew, so it won’t be slow, then. Good.
It’s mildly surprising that this car
exists, but Ferrari is no different to other car manufacturers in that it has
to be Seen To Be Doing Something in environmental terms, despite the fact that
such a small-volume manufacturer contributes relatively little to global
warming. In fact, you could argue that The Car in general contributes little,
but we’ll leave that alone for now. Ferrari has to play the game.
It’s green. That’s obvious. It’s also fast.
But most of all, this 599 is impressive technically. In fact, my impression of Ferrari
as a company has been boosted by the fact that this machine exists. One of
Ferrari’s chief engineers told me that if they were to put it on sale today,
the hybrid system would double the standard 599’s price. Cutting edge, in other
words - because Ferrari’s demands for the tech are demanding indeed. It won’t
be on sale for at least another five years.
Batteries are skinny (20mm thick) and
highly efficient lithium-ion jobs lying flat on the undertray. The motor is
neatly integrated with the dual-clutch transmission at the back of the car. It
is controlled by a neat electronics module located beneath the boot floor - not
an inch of boot space has been lost, though. In fact there’s more, because the
standard 12-volt battery has been taken out of the boot and its function
replaced by the module.
The hybrid 599 has regenerative braking and
stop-start, and the net result is a 36 percent improvement in fuel consumption
(and roughly the same in emissions) over the standard V12. And an 80kg weight
gain is neatly offset by an 80bhp upgrade in power via that electric motor.
There are other clever things going on too, like using said motor to fill
torque holes in the V12’s power delivery. They’re really thinking about how
this can work for a Ferrari.
Shame the F1-transfer of KERS regeneration
tech is now a dead duck, because none of the F1 teams are using KERS this year.
And when I asked an engineer about whether he’ll ever work on an all-electric
Ferrari, he said politely ‘I’d prefer not to think about it’.
