THE F70 (LaFerrari) Thread

Hmmmmm interesting as someone who saw the car last year said same size as 458 but lower roofline...

 

It comes directly from their work in F1, but it obviously doesn't need to abide by the F1 rules. That would defeat the purpose of it being a road car. The same goes for any evolution that comes from the race track. Otherwise a driver wouldn't be able to push the KERS button for more than a few seconds... Or every P1 driver would have to ask his local authorities what section of the motorway he could activate DRS in, etc etc...

 

Anyone else here? Want to grab breakfast or lunch tomorrow? Could use an FF in this weather.

I don't think the 458's could be called active, and although illegal in f1, is not far from this year's passive drs in concept.

What I'm hoping for is something more clever, though, involving fans, diffuser, spinning wheels, space-thrusters, etc. rather than a moving wing at the back.

I must also say that I'm not a big fan of the f1 for the road concept.

I imagine such gimmicks as drs and Kers buttons would be looked at ridicously in a few years, as f1 rules change quickly and an HyperCar should be immortal.

 

I am but only in spirit!

 

No gimmicky kers button, full time kers which is more noticeable from a stop and at low speeds. Rear active aero on upper wing and lower diffuser based on speed. Exact same length as enzo.

 

CAN you confirm horsepower numbers of f150?

 

let's just say in the area of 800hp from NA v12 (similar block to F12) and an add'l approx 150hp from kers which brings you at over 900hp+.

 

Have a good one!

You impressed by the vehicle or do you you expect more?

Will make make it match the p1?

 

Tnx, and tnx Luca.

 

Cool pic - where exactly is that?

 

A KERS "press to pass" button wouldn't be that bad. Anyway...

 

Tanks a lot

 

Giving the driver the option is the way to go. We used it both ways and it can easily be switched. In one mode it's "automatic" all controlled by the foot throttle. In one mode it's button controlled. There are times where both triggering mechanisms are useful.

 

Bologna, Piazza Malpighi.

All Italy is under the snow actually ....

 

I don't see why it can't be controlled by the amount of throttle only, if very intense it gets activated otherwise it doesn't. It's still the driver's choice.

 

Similar to the step down feature of automatic transmissions, which I have always hated.

On the other hand a steering wheel button is positive, but the wheel is getting awfully cluttered. Maybe a foot operated switch?

 

It would be immediate, not like step down. It would actually avoid going down a gear in autos.

I guess the difference is in the fact that on turbo engines the kers is activated automatically to fill in the turbo delay and you need another means of using it while the turbo is already working.

Bench driving KERS is a bit different than actually driving a car with KERS which unlike many I have.

KERS fills in low speed torque until the petrol motor can make enough revs to produce torque. This works the same way on NA or Turbo engines. It's best use is coming out of turns on a race track or as push to pass.

 

Why would you need a button though? It's ok in f1 where it's limited to only get regenerated by braking and just at the beginning of each lap.

On a normal car the throttle action should be sufficient.

And on a turbo there must be some priorities on when it deploys. If you squeeze it at the top of the revs and change gear soon after, wouldn't you feel the lag?

 

You'd want a button because the auto programs that bring KERS on via foot throttle may not suit real world driving and with a button as well as an auto program you can deceide rather than having a computer decide for you.

The latest version of our Ring race program was automatic armed by GPS location after braking for specific turns and triggered for 4 seconds upon the next 100% foot throttle application. On a race track being monitered by 4 KERS engineers and 2 petrol engine engineers and and engineer from the KERS mfg. it worked pretty well but there were times that the driver's still elected to use the buttons and on the road IMO you'd definitely want to be able to control KERS when you, not a computer program wants you too.

 

Many rumors say that tomorrow the countdown will begin on the ferrari website that do you?

 

Here's a video where you can see KERS working. The Toyota system seems to have a little more power than the Audi system. The Toyota system is Super Cap and the Audi battery which may have something to do with it. Super Cap on street cars isn't something IMO we'll see for a bit as they are VERY expensive and a touch dangerous.

One reason that F70/P1/918 all have relatively large battery packs compared to F1 systems is that the useful life of smaller battery systems is very short and these batteries are VERY expensive (tens of thousands of euros). By putting so many of them into the 918 Porsche will be able to offer an 8 year KERS battery warrantee. IMO replacing the KERS batteries after warrantee will be a huge expense.
