akirby Posted April 2, 2009 Share Posted April 2, 2009 A Manumatic is an automatic transmission with a manual valvebody override. As we all know, Automatics don't have a clutch... let alone two. There is no "definition" of manumatic that says it has to be an automatic without a clutch. It can just as easily be a manual with automatic capability like the ones that Ferrari use. It's a combination of manual and automatic. Quote Link to comment Share on other sites More sharing options...
jfalkSVO Posted April 2, 2009 Share Posted April 2, 2009 Does anybody know if the improvement in mpg will lower or eliminate the gas guzzler tax for the GT500? Quote Link to comment Share on other sites More sharing options...
NickF1011 Posted April 2, 2009 Share Posted April 2, 2009 Does anybody know if the improvement in mpg will lower or eliminate the gas guzzler tax for the GT500? From what I have heard, it will eliminate it. Quote Link to comment Share on other sites More sharing options...
Versa-Tech Posted April 2, 2009 Share Posted April 2, 2009 There is no "definition" of manumatic that says it has to be an automatic without a clutch. It can just as easily be a manual with automatic capability like the ones that Ferrari use. It's a combination of manual and automatic. Well first off, by definition an automatic transmission does not have a clutch, period. Second, Ferrari does not offer any transmission that switches gears autonomously. The system you are refering to was originally called F1 Electronic Gearbox, and was a manual transmission with an computer controlled clutch. The current version is refered to as F1 SuperFAST, and no that's not a joke. These transmissions are referred to as Electrohydraulic Manual Transmissions or EMT in Ferrari's original patent, and are currently referred to as such by those in the industry. Dual Clutch transmissions were first used by Porsche under the name Porsche Doppelkupplung or PDK back in the 1980s. The term Manumatic was first used by Porsche in their patent for an automatic transmission developed specifically for use on the treacherous winter Nordschleife F1 race. Porsche found that by using a torque converter on the often snow-covered track, they could run cars more consistently than opponents (by reducing shift induced oversteer). Unfortunately, for the same reasons that Porsche developed the Manumatic, the race was relocated before they could ever use it. Porsche revived the Manumatic technology in the late eighties, and continued to use the original name before switching to Tiptronic in '92 for marketing purposes. So to directly answer your claim, there is a definition for Manumatic. It's in Porsche's original patent. If Manumatic described any manual without a clutch pedal, then Porsche would have simply called their PDK a Manumatic. I could care less if journos use the term loosely, it's incorrect. And before you even say it, I already know that I'm an ASS :yup: Quote Link to comment Share on other sites More sharing options...
