Subaru, a marque that doesn’t come readily to mind when talking
advanced technology vehicles, can be a bit of a tease. Back in 1991,
this automaker all but stunned the automotive world with a sports
coupe that could generously be called atypical – the cutting
edge Subaru SVX. This swoopy, fast, and decidedly cool car didn’t
become a huge seller, but it did establish Subaru’s credentials
as a company that could bring advanced vehicles to the showroom
with the best of ‘em, something we see today in models like
the Impreza WRX STi. Still, Subaru tends to stay on the mainstream
side with such well-engineered staples as the Outback, Forester,
and Legacy rather than heading for the limelight with flexible fuel
or hybrid models.
Well, Subaru has stepped out of the box again, and in a big way.
Its B9 SC “Scrambler” hybrid electric concept blends
the design direction of Subaru’s Andreas Zapatinas –
formerly head of design at Alfa Romeo – with a unique
hybrid
electric drive technology that works seamlessly with Subaru’s
Symmetrical All-Wheel Drive systems, and also is adaptable to its
current vehicle platforms.
This automaker’s Sequential Series Hybrid Electric Vehicle
(SSHEV) system places a generator between a 2.0-liter, 4-cylinder
DOHC Subaru Boxer gasoline engine and transmission with a two-way
clutch, high-performance electric motor, and all-wheel drive transfer
gearing integrated into the transmission case. What’s unique
about the SSHEV powerplant is that its Boxer gasoline engine supplements
the electric drive motor, rather than the other way around. Up to
about 50 mph, the gasoline engine’s primary role is to charge
the laminated lithium-ion batteries that power the hybrid vehicle’s
electric motor.
The gasoline Boxer engine takes over as primary propulsion above
50 mph, a speed range that’s most efficient for this internal
combustion powerplant. Both electric and gasoline powerplants jointly
provide power under demanding driving conditions.
Subaru says it will be able to offer customers the kind of performance
now enjoyed with its turbocharged models by using its own hybrid
electric drive technology. After being blown away by the impressive
performance of Subaru’s SVX while driving this sports coupe
at its debut back in 1991, we have no doubt that Subaru has the
technical savvy and is surely up to this challenge… with a
few more tricks up its sleeve, to be sure.
