Science Meets Sheetmetal By:

“Is that the thing that runs on water?”
“Pardon me?” I exclaim, with a half confused, half
grimaced look on my face; yet another classic
example of mainstream media leading to public
confusion. Current events mix with auto tech about
as well as the weather and sports. Sure, you still
get the score, but what does the dewpoint have to do
with the bases being loaded? Not much. But with fuel
prices looming in the stratosphere, even the
cameraman has something to say about gas savings. So
without further ado, lets dive into the meat and
potatoes of this FrankenUte (and no this isn’t a
culinary review either)!
According to Webster, a hybrid is an offspring of two
different races; in this case, combustion meets GE.
Ford has taken a 2.3-liter four cylinder with
Atkinson cycle combustion and mated it with a 65-kW
electronic traction motor to create the propulsion
system for this engineering wonder. Separately, the
gas engine produces 133 horsepower while the
electric motor emits about 87. Ford claims that when
used together the duo produces 155 horsepower, not
sure who was adding those numbers, but evidently
there is parasitic loss somewhere. A
smaller 28-kW generator motor is used for recharging
the batteries. An electronically controlled
Continuously Variable Transmission (eCVT) determines
gearing ratios, a tranny not found in the standard
Escape lineup. To further augment efficiency, our
tester was equipped with the standard front-wheel
drive setup, but four-wheel drive is available with
the hybrid as well.
Starting up the Hybrid is as simple as any normal SUV.
The engine fires each time you twist the key, so as
to warm fluids up to operating temperature. Once
underway, however, road conditions and power
utilization dictates which power source to use when.
If your motoring through town and hitting stop
lights along the way, the engine will take a
breather and let the electric motor handle things
using power stored in the 330V Nickel Metal Hydride
battery pack under the rear cargo mat. Regenerative
braking is the primary source of recharge energy,
utilizing what would otherwise be lost as friction
heat. When braking alone doesn’t recoup enough
energy, the engine will kick in using the smaller
motor in reverse like a generator. Like any other
hybrid, the Escape is most efficient in the city
where the brakes are used most often. However, as
Editor Dye found out, even over long highway miles
where the gas engine is the primary source of
propulsion the Escape was capable of delivering 30
mpg. When extra power is needed for passing or quick
acceleration, both the battery and engine are
sourced to deliver V6-like performance. Driving the
Hybrid is for the most part like driving any other
Escape. The powertrain feels a bit smoother, with a
bit of a disconnected feeling--being that most of it
is electronic. The engine sounds a little coarse at
times, depending on where the revs fall, but the eCVT is much smoother and graceful at its work than
the CVTs found in the Five Hundred or Freestyle.
Driving with the engine turned off takes a few
minutes to get used to, especially when all you hear
is road noise and the fan cooling the battery pack.
Seeing the rpm gauge fixed on 0 while doing 25 mph
is pretty cool as well.
Appearance wise, very little actually distinguishes our
Escape Hybrid from that of its less efficient
brethren. Apart from the Hybrid badges adorning the
flanks of the sheetmetal, silver lower accents and
unique 5-spoke wheels are all that set the
gas/electric’s apart from the petroleum burners. Our
green (as in environmentally safe) Escape came in an
environmentally friendly Titanium Green finish (as
in paint). The interior remains as cheap as ever.
All of the same gripes we had about the last
non-hybrid Escape we tested still exist. Hard
plastics, hard armrests, cheap feeling touch points
and acres of more hard plastic top the list. Added
safety features including side airbags and head side
curtains did find their way onto the options list
and were checked for our vehicle. Also checked was
the Hybrid Energy display monitor with Navigation
system. While being a cool feature, you gain very
little for the $1800 you pay out. The screen
displays where the power is coming from and going
to, but there is little useable information from
this. The screen is small and the Navigation system
requires the use of a CD, thus you can’t listen to
the Stones and find directions at the same time.
So what is the real benefit of owning a hybrid SUV?
Well, for starters, you won’t have to borrow your
neighbor’s F-350 every time you want to pick up more
than one bag of mulch from the local greenhouse,
just because you want a commuter car that is easy on
your wallet at the fuel pump. That, and it is a bit
amusing to silently roll up to a stoplight next to a
guy in his Civic with the windows down and a Sierra
Club bumper sticker on a hot sunny day while you’re
running on electric power, have the kids in the back
seat eating ice cream, listening to SmileFM and have
the A/C on.
Unfortunately, there is always a downside. Technology
comes at a cost. In the case of the Escape, a
similarly equipped non-hybrid model will save you
about $2,000 in initial cost. If you crunch the math,
at 12,000 traveled miles a year using 22mpg for the
non hybrid and 33mpg for the hybrid, at $2.20 per
gallon of gas, it will take five years to see the
benefit of that extra dough spent upfront. However,
if you plan to put more than 60,000 miles on your
vehicle in 2 years or less, than you have a business
case. As well as being that much easier on the
environment. All those extra components add weight
as well, with our front-wheel drive tester tipping
the scales at 3,620 lbs; or just under 200 lbs more
than the fully loaded Limited 4x4 Escape that we
tested a year ago. Fortunately, the Hybrid carries
its weight well, distributing the load by placing
the battery pack at the rear of the vehicle.
In retrospect, Ford has built an all around very
practical, efficient SUV. The hybrid system works
seamlessly and will surely lengthen the time between
fuel stops. Ford claims a 400 mile range on a tank
of gas, while we didn’t achieve this number, it
isn’t out of the question considering our feet are
heavier than most and our trips were long with the
A/C cranked up (which we found to be just a bit weak
by the way). Last time we reviewed an Escape we
found it hard to justify the near $30 grand sticker
price. With the Hybrid powertrain however, this
unique piece of technology makes the sticker more
attractive. Our front-wheel drive model listed out
at $30,825, so if you can live without 4-wheel drive
and you dump the Nav screen option, it is possible
to drive a nicely equipped Hybrid Escape home for
about $29 large. Not bad, all things considered. And
no, I don’t know who will win the playoffs, but I
can tell you that you don’t have to plug it in at
night!

|
 |
| The
Good: |
|
High-tech powertrain, much welcomed fuel savings.
|
| The
Bad: |
|
Still a cheaply furnished interior, higher initial
cost.
|
| The
Verdict: |
|
With all the high-tech, fuel saving gadgetry, it’s
easier to forgive a cheap door pull and a hard armrest.
