Plug-in hybrid production planned in 2010 by Saturn
Saturn announced that production may begin as soon as
2010 on a plug-in hybrid electric version of the Saturn Vue Green Line,
expected to be the first regular production plug-in hybrid electric vehicle.
Depending on a consumer’s drive cycle, the Vue plug-in hybrid will be
the most fuel-efficient vehicle offered by a major automaker.
This Vue Green Line will use a modified version of GM’s two-mode hybrid
system and plug-in technology, a lithium-ion battery pack, highly efficient
electronics and powerful electric motors to achieve significant increases
in fuel economy. When the lithium-ion batteries are fully charged, the
Vue plug-in hybrid will potentially double the fuel efficiency of any
current SUV. After electric-only propulsion depletes the lithium-ion
energy storage system to a specified level, the battery is replenished
by utilizing the two-mode hybrid system’s electric motors and regenerative
In early testing, the Vue Green Line plug-in hybrid is capable of electric-only
propulsion for more than 10 miles at low speeds. At higher speeds or
when conditions demand it, such as brisk acceleration, a combination
of engine and electric power or engine power-only drives the vehicle.
The vehicle’s lithium-ion batteries can be fully recharged in four to
five hours by connecting the vehicle to any standard 110V household electrical
outlet. The connection port on the vehicle will be integrated into the
A plug-in hybrid-electric vehicle differs from a non-plug-in hybrid-electric
vehicle by offering extended electric-only propulsion, additional battery
capacity and the ability to be recharged from an external electrical
The two-mode hybrid system to be introduced on the 2009 Saturn Vue Green
Line 2 Mode will be altered for use with plug-in technology. In addition
to plug-in capabilities and the modified two-mode hybrid system, the
Saturn Vue Green Line hybrid SUV’s powertrain will feature two interior
permanent magnet motors within the two-mode transmission and GM’s 3.6L
V-6 VVT gasoline engine with direct injection. The lithium-ion energy
storage system will be replenished by utilizing the two-mode hybrid system’s
electric motors and regenerative braking systems.
