Subuaru Hybrid
In
late 2003 Subaru unveiled its hybrid concept; the Subaru B9 Scrambler
(later renamed the Subaru B9 SC in America,) an inspiring performance
hybrid featuring an electric motor powered by a 2.0 liter SOHC flat-four
cylinder engine. The B9 Scrambler may not seem Subaru by style,
but certainly is by function; the roadster is all wheel drive and
rides on an adjustable air suspension, allowing changes to ground
clearance as needed. It also features a dent, scratch, and ding
resistant body. The large wheels, high arches, and sporty wedge
may give the B9 Scrambler the edge it needs to transcend Subaru's
current demographic without alienating faithful enthusiasts.
So will the B9 SC ever hit the streets as a production
model? Sadly, the chances are slim, but the release of this concept
shows that Subaru is interested in hybrid production and may use
the technology developed for the B9SC in one of their other automobiles.
Perhaps your interested would be piqued by a Hybrid WRX?
A little more from Subaru Media on the B9 SC hybrid
system:
"The hybrid system in the Subaru B9 SC is
ideally suited to work with the brand's existing Symmetrical All-Wheel
Drive systems and could be adapted to current vehicle platforms.
The hybrid drive technology itself differs significantly from that
used in most current production and proposed hybrid vehicles. In
most hybrids, an electric motor is used to assist an internal combustion
engine. The Sequential Series Hybrid Electric Vehicle (SSHEV) propulsion
system in the Subaru B9 SC works the other way around."
"The SSHEV system teams a powerful electric
motor with a 2.0-liter DOHC Subaru boxer 4-cylinder gas engine.
At low and midrange speeds, the gasoline engine is used primarily
to charge the advanced laminated lithium-ion batteries. At speeds
over 50 mph, the B9 SC runs only on its gasoline engine. Thus, the
internal combustion engine always runs in its most efficient speed
range. To provide extra performance on hills and when the driver
demands quicker acceleration, the SSHEV system seamlessly combines
output from both the electric motor and gas engine through a special
two-way clutch. The compact SSHEV propulsion system could easily
be housed within the footprint of the Symmetrical All-Wheel Drive
system used in current Subaru models. The SSHEV system places a
generator between the Subaru Boxer engine and the transmission.
A two-way clutch, the high-performance electric motor and the AWD
transfer gearing are all neatly integrated into the transmission
case."
"Symmetrical All-Wheel Drive, height-adjustable
suspension and large wheels with run-flat tires give the Subaru
B9 SC concept trail-driving capability, making it a sports car for
all roads. The concept vehicle's lower body features a special protective
paint that also wraps over the upper body behind the doors to provide
unity to the design. The windshield is made of a special mirror
reflective glass."
