from Axis...
"The 4wd system is brilliant, it's a Ferrari patent developed over six years ago. Half the weight of any other all wheel drive system, it works with two completely separate gearboxes one rear transaxle and one mounter transversely in front of the engine. There are two driveshafts and is no center differential.
The front gearbox has two forward gears and reverse with one clutch per axle. It's geared so that first will overlap first and second gear on the main rear transmission, second will cover third and fourth in the back. From fifth gear up the car is only driven by the rear wheels. It all sounds complicated but the idea is to minimize weight, mechanical losses and loss of the traditional rear wheel drive feel. The FF is in effect a RWD car up to the point when the computers detect there is excessive slippage, then up to 30% of the torque is vectored up front."

I, for one, do not understand how two front gearbox gears can overlap four corresponding rear gearbox gears.

It has a rear 7 speed dual clutch box in the rear. The front gearbox is totally independent of the drive to the rear, there is no powersapping front driveshaft or center differentials. The wheels are also independent of eachother, power is sent to whatever wheel needs it, similar to the GTR or EVO

wow thats f-ing amazing. 660hp, awd, seats four. look at that suspension travel!

if the subaru coupe was even remotely as amazing. i'd pay 40k for a premium coupe with awd, flat6. ferrari was able to figure out utilizing awd is a front-midship layout.

My brain can only parse things like "gear ratios". Ferrari's explanation makes no sense to me: how can one front ratio cover two back ones? The input shaft driving the front and rear gearboxes is rotating at the same speed for each, unless there's a third gearbox in there somewhere

There has to be some slippage, and it seems this is how they do it. Think it as of DCCD on steroids, that turns completely off sometimes:

http://www.topgear.com/uk/car-news/f...-ff-2011-01-25

So what about the four-wheel drive, then? Uniquely, power is also taken off the front of the engine, which is behind the front wheel centres. It's fed to a compact lightweight unit containing a set of clutches that can progressively feed in torque to a tiny integrated gearbox and front diff. It has only two gears, roughly the equivalent of third and seventh in the main box. How can this be? Because the clutches are always slipping under electronic control, and the front tyres would never be able to make use of all the V12's torque in first or second.

This is either going to be the most insanely awesome way to make an AWD transmission, or the most maintenance intensive drivetrain design in the history of EVAR.

VVV Those are artificially fixed ratios. In actual operation, the "holes" in your torque split map are filled by the front clutches slipping.

"Torque split: 0:100 in 1st gear, 5:95 in 2nd, 10:90 in 3rd, 0:100 in 4th, 5:95 in 5th, 10:90 in 6th, 15:85 in 7th"



It doesn't seem like a good idea from my armchair-engineer's position.

Ferrari patented the system over 6 years ago, it's been in R&D for at least that time. I'll try to find the video explaining it's operation, it was shown at the premiere of the car

That sounds like an awesome way to get highway/cruising fuel economy improvements.

Terrible name for a Ferrari though.

Oh... too late...

I didn't like the car that much before - but that video was intoxicating. Just watching a Ferrari doing slides in snow was something I hadn't really thought would be so cool...

Meh... just dramatic singing and a car driving around. Only thing intoxicating would be the sound, but that's solely the engine.

More info on the 4WD system

EVO Magazine interviewing head designer of the FF Amedeo Felisa

How does it work? (4WD System)
All the power goes to the rear axle until the point where the system sees there is not enough grip to transmit all the power being asked for by the driver. At this point, the hydraulic clutch in the front gearbox starts to 'close', transmitting the extra power being asked for to the front wheels. Up to 30 per cent of full power can go to the front.

This front gearbox only has two forward speeds, why?
In order to make it as light as possible, the hydraulic clutch overcomes the inevitable speed differential, so there is almost always some slip occurring. "first" gear covers first and second gear in the main gearbox and "second" covers third and fourth. Once you are traveling beyond 180km/h, the system reverts to rear wheel drive only, as there should always be enough grip at the rear wheels to transmit full power. If there isn't, you're probably in the middle of an accident and 4wd will not save you anyway!

The image of a Ferrari drifting through snow dunes is utterly ridiculous, and very cool at the same time!

im pretty sure that he meant why couldnt subaru do it for $30k... most nasioc'ers want everything for under $30k these days ... anything from ferrari level performance to audi interiors to mercedes build quality to exotic porsche sound... all for under $30k and cheap aftermarket support and no desire to let stealerships do anything except for warranty work after mods messed up the cars....
