    apparently the murciolago is a bugger of the line because you need to get it rolling before you can floor it - apparently it stalls if you dont (cant imagine that happening myself), this is of course a manual car

    EDIT: of all auto-manuals da de das i like DSG but it still removes driver involvement, i like driver involvement.

    Maybe thats something to protect the clutch, mutch like EVO's are limited to 5000rpm on launch.

    Is that so the engine stops when you do, or you like the very strange sound that they make as the engine note is constant?

We are choosing chassis layouts already yet have not outlined the cars target cost, audience or purpose. I'd rather come to a choice of above after seeing it in context - not by copying others. Drakkie your dexcriptions are accurate and i in no way wnat to diss the project - its just a suggestion. Happy engineering!
    Learning moment for me !!!

    I must say though,money and market plays less of a role then it would in real life...

    I like (i am not the only one deciding however) the sound of a changing engine and the ability to double clutch (if i had it) so you have a point, i however will proceed with less sarcasim. Come on team - work it out

    sorry for being blunt. I will leave you all to choose what you want, i didnt realise this would be a just-on-paper project. It would be a shame to produce another concept car and not a half-marketable automobile

    No need to apologize, mate !

    Offcourse, if we would find a manufacturer to join us, then it would really be cool. But who's interested ?

    I don't think you need to worry about a lack of low end power. Seeing as we will probably be using a V12 of at least 6L...
    Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
    Engine torque is an illusion.

    Can I suggest that you start a new thread covering the basics. Like what kind of car (race car, GT, saloon etc), target demographics etc. These things ARE very important when choosing certain technical aspects of the car.

    And one that appoints project leaders ? Like you suggested in the other thread. Like a Driveline department leader or an Engine design leader etc.

    it would be nice to see use of heterogeneous fuel mixture control for reasons we have seen explained

    I'd love to make this thing a beast but I would also like to see it being as environmentally friendly as possible.

    Suggestion will be executed swiftly

    Entries are still open. I am now organizing the entries into a handy Excel-sheet. Will post it later in the other thread. Then I guess each department on it's own should choose their leader ? I can't please everyone,so they should on their own.

    So far I'd like to thank everyone thinking with me. These suggestions really help me. Furthermore I feel as if I allready learned some stuff, which is always a good thing !

    its funny how most people want a lotus elise style layout. does that mean the engine will be transversely mounted like the ferrari 308GTB

    or Cizeta V16T

    Hahaha then I would blame the driver in your case
    forgot to let the clutch all the way out didn't you?

    just because it is clutchles doesn't mean that the engine has to stop when the car does. The engine will not run at constant revs all the time if you pull away with low thottle opening then the engine revs stay low. However if you floor it then you accelerate at max power (pretty high revs but not redline). CVT would be designed to get the best economy during low throttle openings and power for larger openings. For the people who just can't handel that then there is always paddle shifters. Come on when I thrash my little bimmer I always wish it would stay at about 7200 to hear the sweet tune. But I wouldn't want it to pull away from the drive thru doing that!

    You could maybe open up a few threads with polls to chose the project leaders, project members could maybe post a little "cv" that tells us what their skills are.
    After the leaders are chosen these threads could be closed to minimize clutter.

    May I also suggest a sort of "General Technical Questions" thread were you can ask certain technical questions to all members so you don't limit yourself to the knowledge that is in your own project group. Questions like: is there a material out there that disintegrates completely upon impact ? (I'd like to know this ). Or maybe what type of clear plastic is the strongest or lightest etc.

    Could we also open up a temporary subforum ? Like we had with the first UCP supercar ?
