Unfortunately,
Ford has recently pulled back on its hybrid vehicle
plans and this seems sure to affect the Tribute hybrid.
In fact, there were even rumors that Ford wasn't even
going to produce the Tribute hybrid, however, Ford
eventually squashed those rumors and confirmed its
commitment to the hybrid Tribute.
How many
Mazda Tribute hybrids Ford will produce is the real
question.
How the Tribute hybrid
does it.
Combining two electric
motors, one to drive the wheels, the other to turn over
the gas engine, with the standard Tribute 2.3 -liter four-cylinder gas engine,
the Tribute HEV is expected to get 35 mpg and perform
as well as the 200-hp V-6 version.
The hybrid Tribute's gasoline
engine has been modified to run on the Atkinson cycle,
unlike the standard Tribute, which like all conventional
automobiles, runs on the Otto cycle.
This cycle runs more
efficiently, using less air and fuel, but also reduces
engine horsepower, and that's where the electric motors
kick in.
One motor drives the
wheels on the Tribute hybrid, the other starts the engine
and manages the transmission's ratio.
These electric motors improve fuel economy in city
driving, allowing the vehicle to be powered by electric
power only, and by capturing energy more efficiently.
Yes, you still have to keep gas in the hybrid Tribute.
Similar to other
hybrids, the Mazda Tribute will utilize a variable
transmission system, which Ford calls Electronically
Controlled Continuously Variable Transmission or eCVT.
This allows the distribution of power between the
gasoline engine and the electric motor to be determined
by driving conditions, allowing the gas engine to shut
off when the electric engine can provide enough power to
run the hybrid SUV - significantly increasing
fuel-efficiency.
