    Sorry to start another thread, but it seemed appropriate to keep this info in one place..

    Can we make a collage of all the know/confirmed specs that we are aware of. Ferrari is still being way to criptic about the car.. We still don't know the battery capacity, for how long does one full discharge cycle last.(ie how long will you have 163 electric hp at your disposal onece you plant your foot down in). also the weight is semi unknown, as well as the drag coeficient and downforce.. basicly we don't know much more now then we did before launch. except how it looks and is called.

    Here are the specs from the site..

    E-Diff 3
    third generation electronic differential
    SCM-E Frs
    magnetorheological damping with twin solenoids (Al-Ni tube)
    Aerodynamics
    active

    We hear the (i gues curb) weight will be around 1350kg(same as enzos ?). the Aero section says the drag coefficient is close to 3. The battery capacity is said to hold 40 traditional batteries.. from this if we use even the lowest possible battery 45Ah that;s 40x45Ah 1.8kA at 12V which is 21.6KWh and this figure makes no sence at all as even the most efficent Li Ion batteries only have around 265Wh per kg, which comes out to ~16KWh at 60kg.. the figure also doesn't make sence if we know Porsche has only 6.8Kwh and is much heavier..

    I'm pretty new to these electrical jargon.

    Just when you thought you understood cars, they introduce wattage, amps and voltages.

    Relativly simple :)

    P = I x U
    P = Power, I = Current, U = Voltage

    P x t = E
    t = time, E = Energy...
    Since batteries are ratied in Ah which is Ixt you get that (Ixt) X U = Pxt => E = IxUxt...

    P.S. here is why engineers will never have more money then business men
    1.Everyone knows that money = time
    2.Everyone knows that knowledge = power

    Since Time = Work / Power

    Money = Work / Knowledge

    LaFerrari battery pack weighs 60kg.

    Let's assume Lithium energy density of 1 MegaJoule per kilogram (not quite best possible), this means LaFerrari battery energy storage of approx 60MJ.

    This means that the batteries (fully charged) can provide the specified 120kW (160hp) for a time period of 500 seconds ... or just over 8 minutes.

    Even if we provide a significant de-rating factor (taking into account temperature, long term reliability, etc), and say that the batteries can only store 0.5 MJ per kg, then we still conclude that the batteries can supply the specified 120kW (160hp) for 4 minutes.

    Sounds fine to me !!! :)

    EDIT : there's no track in the world where you can drive for 4 minutes without a braking event for recharging. Ferrari's battery pack sounds plenty big to me ...

    That would still imply that even at 30 MJ. te ferrari would have 8+ KWh, then I am wondering how in the hell does porsche only have 6.8KWh for a car wiht twice as much electric power, and weighs 300kg more.. something is way off here... My guess is the quoted 60kg is for the entire battery pack cooling and pumps and all. IMO more realistic figyre is ~60-100 sec of full blast... Which is more then fine :D

    Because I love the way ferrari through out fuel consumption to the wind and engages and uses the engine to charge the batteries at every opertunity, basicly the engine is working full on most of the time... while the turbo boost is being recharged at every non full throtle moment love it..

    relatively easy to do if fly by wire is used. when the driver lifts his foot of the gas insted of cuting flow to the engine, you activate the generator to start slowing the engine down...thus emulating a lifted foot of the accel..

    I do hower worry about what the heck will happen when a transistor decides do go haywire..:D

    The risk of fires and electronics related crashes just went up a few percent with these cars..

    could very well be ... 60kg might include cooling and packaging
    absolutely agree. Unlike the competition, Ferrari didn't try to store enough KERS energy to be able to drive on electric alone for xx miles, or yy minutes. That's a DUMB goal for a hypercar, IMHO ... no need to make your hypercar a little bit like a Toyota Prius or Chevy Volt, just for silly marketing reasons :rolleyes: In fact, this is the single BEST thing about LaFerrari KERS : single-minded focus :)

    Instead, Ferrari focused on enough electric energy to improve laptimes ... so even 100 seconds or maybe 2 minutes of 160hp "boost" is probably more than adequate for most tracks (won't go that long without a braking event for at least partial recharging).
    I hear you ... the cars have definitely gotten more "electronically complex", and that worries me too (and I'm an electrical engineer!). But i said that when the industry moved to fuel injection, touch-screen controls, etc etc

    I would take 0.4 MJ/kg for the energy density of the Li battery. Also figure at least 10% losses in electrical delivery. But it is still meaningful energy as you point out.

    A note in passing. Gasoline has an energy density of close to 50 MJ per kg, more than 100 x a Li battery. It is the best battery known to humans. That is one reason why the pure electric car is dumb.

    There are 2 registry/where are cars going threads. None have even been sold yet. This is getting out of hand.

    The official LaFerrari site Design | LaFerrari ? Official Site acknowledges the influence of the 330P4 and 312P, but not the P4/5. It also contains interesting data.

    For example the dimensions given show that LaFerrari is exactly the same length as Enzo (4702 mm, or 185.1 inches). LaFerrari is actually slightly narrower at 78.4 inches vs. 80.1, and is yet lower at 43.9 inches vs 45.2 for the Enzo. The suspension is conventional with double wishbones in front and a multilink rear. They claim a greatly reduced braking distance (30 m less from 200 km/hr) via super lightweight Brembos. The horsepower figure for the engine includes an unspecified amount of ram effect.

    The site is worth going through for those interested in information on the car.

    You can't calculate with the traditional Lead acid values (12V). 265Wh/kg is for experimental cells at cell level, if you take real production cells and put a housing around them and add a cooling system, you end up at ~75Wh/kg on the system level. I expect the battery to have 2-4kWh if it weighs 60kg.

    And they'll need to limit discharge to leave about 30% in the battery for longevity, unlike gas.

    Usually you have a charging window for optimizing battery life. The Prius II for example operates between 40% and 70% of the installed capacity, if I remember my colleagues' measurement correctly.

    (Of course the display shows 100% and 0% to the driver at the real 70% and 40% values).
