The Sierra Hybrid automatically
and seamlessly selects the best
operating point for the powertrain
to deliver both fuel economy
and performance while also
reducing gear “hunting” associated
with trailering.
During normal stops, regenerative
braking uses the motors in the
hybrid transmission as generators
to decelerate the vehicle by apply-
ing resistance in the motors rather
than brake friction. At the same
time, the motors are capturing
that energy as electricity in the
300-volt battery pack, electricity
that is available for the next ac-
celeration cycle.
At low speed and with a light
load, Mode 1 can employ elec-
tric power alone, engine power
alone or a combination of both.
It reduces fuel consumption in
stop-and-go traffic by shutting
off the engine and operating on
electric power alone. The result is
an EPA-estimated 21 mpg in city
driving, a 40-percent improve-
ment over the traditional engine.

At highway speeds, AFM uses
either V-4 or V-8 operation—some-
times with supplemental electric
power as conditions warrant. Full
V-8 engine power is used when
conditions demand it — such as
passing, trailer towing or climbing
steep grades. On the highway,
Sierra Hybrid has an EPA-estimated
22 mpg.
