Tansmissions-Powertrains
The EPA documents published on hydraulic hybrid research in 2006 included some projections about the potential improvements in mileage from various system improvements.
The greatest improvemnt with a peak projection of 80% was in the powertrain itself, with all other engine, aero, and tire rolling resistance increasing that 80% to a total of 120%. This has been coinfirmed by developments from various sources in the 6 years since the document was first published and has verified the accuracy of the original projection.
These projections also assume testing will be in exactly the same method as current EPA tests, which would eliminate extreme cases of hypermiling which do not match those same testing standards.
In thise series of threads I am going to discuss what I believe will be the future of powertrains. I will also relate my experiences with some of the newer developments in Continuously Variable and automated manual transmissions.
I fully understand that many of the best hypermilers use manual transmissions exclusively.
ANY HUMAN VEHICLE INTERACTION CAN BE RECORDED AND PROGRAMMED AND RENDERED AUTOMATIC.
The human interaction demonstrates the fact that the manual transmission is still king as far as efficiency, but only becasue of the unique way a highly skilled hypermiler can make it function, as well as using techniques that in the hands of less skilled operators, without a lot of practice could be dangerous and in some cases are technically illegal in some states in the US, even though the exact same techniques are considered legal when they are incorporated into a hybrid or pure electric vehicle design.
