GM has no intention of releasing large numbers of VOLT. It's all a PR
ploy. GM has stated to NHTSB that the VOLT won't be produced in more
than tiny number through 2014, and should not be counted in GM's
supposedly desperate struggles to meet MPG standards.
GM's EV1 was never marketed by GM, never offered by sale by GM, and
was sabotaged orginally by GM's failing Delco batteries. GM had, in
1994, bought control of, and suppressed use of, the NiMH batteries
that last longer than the life of a car.
It was Toyota, in 1997, that proved that NiMH batteries were
successful, and GM had to react; it reacted by selling control of the
NiMH patents to Chevron, which then funded a lawsuit against Toyota,
collecting $30M after which Toyota ALSO stopped producing an EV.
These Toyota RAV4-EVs are still running, over 100 miles range, proving
that GM's "quest" for 40 miles range is just a dodge and a lie. They
had a serial hybrid in 1969 (Oldsmobile) and 1999 (a version of the
EV1).
GM is just trying to delay things until gas prices come down; only the
gullible believe GM.
