An Electric Jeep Wrangler? Chrysler says YES!
A Promising Future
Jeep's foray into the electric vehicle is one of the bullet points of its
future propulsion strategy, and based on the information we have, we feel that
the future is full of promise for Jeep. The real challenge, though, is for
Chrysler tech engineers to build an electric vehicle Jeep enthusiasts won't pass
over. What they've come up with so far is a Wrangler Unlimited that uses an
electric motor to drive the rear wheels, lithium-ion batteries to store the
energy, a super-computer controller to manage the energy flow, and a small
engine/generator needed to produce power when storage ratings in the batteries
fall below 30%.
Electric Power in a Jeep?
Moving on full electric power for up to 40 miles the Jeep EV then kicks into
hybrid mode, where the generator produces power directly to the electric motor
as necessary. Any extra energy during braking or off-throttle situations will be
routed into the batteries. The gasoline tank (which can also hold E85 fuel) will
allow the vehicle to travel, depending on the types of loads and environmental
conditions, an extra 400 miles or so. In addition, because of the capabilities
of the on-board dual-voltage generator, the Jeep EV can have a 15-amp
110/120-volt outlet as well as a household 30-amp 220/240-volt power outlet.
The Jeep EV packs a punch with strong and smooth acceleration, ramping up
power progressively where the vehicle just keeps pulling up the speedometer at
an almost unnerving pace. Being all electronic, the console-mounted stick shift
is gone and the gear selection is done by pushbutton just below the nav screen.
The nav screen itself allows for several different options to help the driver
monitor all sorts of vehicle parameters like battery temperature, power levels,
strength, range, charge/discharge direction, and more.
Handling and Capability
During driving, the added weight underneath the vehicle helps to take away
some of the Wrangler's usual "tippy" feel when cornering at higher speeds. Of
course, all test driving was done on pavement, but the Jeep guys said this
vehicle has to be able to do everything people expect a Jeep to do if it's going
to be a success. In fact, we've been hearing that a pair of wheel-mounted
electric motors could work on a future model to make the SUV more trail capable,
but the computer power needed to make the front and rear motors sync is
prohibitive. Our guess is that it's still a few years out at best, but opens up
all sorts of ecofriendly 4x4 possibilities Jeep is hoping will catch on. The key
will be to make them work like a typical 4x4. In the 2WD vehicle we drove, there
was nothing that made the vehicle look or act compromised, with the exception of
noise and absence of a transmission. Additionally, under the hood was tons of
room to store various gear and tools, or mount a winch.
Only one of the models that Chrysler has had for demo will be available in
2010. To us it would make the most sense and be an easier fit in the Town &
Country as they are priced better to deal with the added technology, the
platform has built-in under floor storage capacity for the batteries, and it's
just about the only segment making money right now. You can expect more on this
coming in the near future. And we'll see if we can get a few more tidbits from
the Chrysler EV development team at the L.A. auto show.
ENVI Technology
ENVI which takes it's name from the first four letters
of ENVIronmental is Chrysler's foray into the electric vehicle realm. ENVI's
variations on this "updated" electric theme appear on three different
platforms-front-wheel drive, rear-wheel drive, and four-wheel drive-and from all
three brands: Dodge, Chrysler, and Jeep.
The other technology ENVI developed went into the
Chrysler and Jeep products: the Town & Country minivan and Wrangler. While the
Dodge is called "electric," these two are referred to as "range-extended
electric." The first clue that the Wrangler isn't the Renegade? Gas, not diesel.

Chrysler uses the word "modularity" here-as in, the
minivan and Wrangler can share hardware (let's hope the electric power train is
the only modularity mentioned for these two in the future). Like the Renegade
(and Volt), the battery pack in these two EVs can run 40 miles on one charge
(Chrysler says 40 percent of us are driving less than that each day).
The small
engine and electric generator are there for up to 400 miles of
refueling/recharging freedom. The recharge comes from run-of-the-mill household
electricity, just like your cell phone. However, we hope that unlike our cell
phone, the Jeep battery will still hold a charge after a year.
Besides the differences in the regular and EV Wrangler
power trains, there's the center of gravity. The EV's is significantly lower; the
battery pack is axle height. However, Chrysler says the weight of the two
Jeeps
is about the same.
Chrysler swears an electric vehicle
is going to be available to the public in 2010 (like the Volt). And while we
implied that this Jeep was a '10 model in the title, the truth is that none of
these three may see the light of day. It could be another front-, rear-, or
four-wheel-drive Dodge, Chrysler, or Jeep product.
Jeep seems to be pulling ahead of the pack once again by making strides into new technologies which set
them apart from the competition. This is an atypical trait for Jeep. Wrangler is
somewhat of a throwback, with live axles, mechanical locking differentials, and
part-time four-wheel-drive systems. The need for advanced technologies is
certainly there, and the decision makers at Chrysler seem to have heeded the
call with the research and development of these and other new technologies.
