Nika, reminds me of the scene in "Gone in 60 seconds" when Cage and Jolie are waiting for the Lambo guy and his chick to finish their business. The Technicalities of transmissions never sounded so good!  | ||

Thanks Nika and Bret, for your reply....I was just watching my question go down down down down the topic list...unanswered....and I was thinking...oh boy I must've asked a dumb question. LOL | ||

Most transmissions are "geared" so that the ratio's take best advantage of the engines "power or torque band " ...in other words the gear ratio's are chosen to hopefully allow the engine to perform it's duty when it is in it's best working range of power production in order to get the maximum power to the wheels for the duty cycle that the vehicle was designed for. The relationship between engine power production and gear ratio choice is of course a big compromise (as are all relationships ) because the driver desired wheel speed or the speed of the vehicle may not necessarily match any one ratio when the engine is in its best power producing RPM... this is especially true on a race course when you don't want to be really up or down shifting in the middle of a corner if you can at all help it. In race cars we change the gear ratio's at the track to get the best overall compromise for any given track - -- if you could have a transmission that could allow the engine to just continually produce peak power at a constant RPM and the transmission did all the changing it would be theoretically an ideal world --these devices do exist- a lot are used in industrial applications and some vehicles that are built to belch out cleaner air than they suck into there green shoe-box home appliance with a vengeance styled bodies But they haven't replaced the scream of a V12 going up and down through the gears so far ...thank the powers that be !!!!! | ||

I think it's an excellent idea to replace automatics, that's it. Wouldn't want it anywhere that there is a manual now. I'm a little skeptical about the system as well because it will require unGodly amounts of pressure to hold that chain between the cones for anything more than a 150hp Audi. They don't even offer it on the quattro equipped cars yet which makes me doubt its ability to handle torque. | ||

Come on guys!!! Was this a dumb question? | ||

I know this might belong in the Technical Forum but since many of you come to General Discussion anyway, I thought I might get a larger response to these questions: How do you guys feel about CVT (Continuiously Variable Transmissions)? Audi says it permits infinite gear ratios, better fuel economy, less power loss due to lack of a torque converter, etc...Now, can you picture it in a Future Lamborghini? Does it take away from the drivers experience, involvement? Does it have a long way to go (technically and acceptance by performane minded drivers) before it is feasible for the companies to actually include it in their sportier models? Can you imagine one on a Ferrari? Perhaps a 456GT-like touring car? Thanks in advance for your imput, you guys/gals are a great bunch of people! |
