Borg Warner announces new single-speed eGearDrive transmission for Coda electric sedan — Autoblog Green)
BorgWarner, the designer of the gearbox for Tesla's roadster has been nominated for the "prestigious 2010 Automotive News PACE Awards, recognized around the world as the industry symbol of innovation."
(Here's a link to past PACE Award winners & finalists.)
Quote:
Through its high efficiency gear train and compact, low-weight design, the BorgWarner
eGearDrive(TM) transmission contributes to extended battery-powered driving
range which in turn reduces the required amount of battery capacity needed.
The transmission also achieves higher torque capacity with 98% efficiency,
while providing smooth, quiet operation. Approximately 99% of the materials
used in the eGearDrive(TM) transmission are recyclable.

98%!
Something to be said for a single speed transmission, for sure.
(Makes me want to open up the ForkenSwift's gearbox and get rid of all those extra wasteful gears that are uselessly meshed together all the time.)
