Allison Electric Drive System |
|
|
Metro's new hybrid buses are powered by the
Allison Electric Drive system, which reduces
exhaust emissions up to 90% compared to
conventional combustion engines.
Up to
a 60% improvement in fuel economy has been
demonstrated in a vehicle with an Allison
Electric Drive.

Regenerative Braking |
|
|
Forty
percent of the energy to accelerate the bus is
energy saved during regenerative braking. When
stopping or decelerating, vehicle energy is
converted to electric energy and stored. In
effect, the motor becomes a generator.
An
Allison Hybrid Electric Drive System can
significantly out-accelerate a vehicle equipped
with a conventional drivetrain or an alternative
fuel system.

Allison Electric Drive System - EP
System Familiarization |
|
|
As explained
by Bill Nye the Science Guy!
Learn more
about the EP System, a parallel hybrid that blends
both mechanical and electrical power paths to drive a
vehicle.
By using a
smaller internal combustion engine, and operating it
only in its most efficient ranges, the EP System
reduces fuel consumption and emissions and increases
productivity and passenger comfort.
