This truck has an all-hydraulic transmission that stores braking energy and uses it to turn the wheels.
In electric trains, the braking energy is converted into electricity and fed back into the overhead power supply.
The technology in question is KERS (kinetic energy recovery system) for capturing and storing the car's braking energy instead of wasting it as heat.
To meet those standards, GM must install smaller battery packs in autos and implement mechanisms that regenerate braking energy and shut down the vehicle's engine when it's idling.
It converts kinetic energy gathered while braking into electrical energy and stores it in a flywheel.

The hybrid recaptures energy through a process known as regenerative braking -- where the energy normally lost through braking or coasting goes to power the electric motor.
The Volt also has a regenerative braking system that recovers some of the energy of braking as a charge to the batteries.
While the car is on the move, the electric drive itself contributes to a favourable energy balance through recuperation, by converting kinetic energy into electric current in deceleration mode and during braking and feeding this energy into the battery.

The new locomotives are designed for easier maintenance, will improve energy efficiency by using a regenerative braking system that will feed energy back into the power grid and will enhance mobility for the people, businesses and economy of the entire Northeast region.
They capture energy during braking and release it during acceleration, all within a range from 75% charged to 45% charged.
However, the electrical version of KERS is not the only nor possibly the best way to capture kinetic energy during braking and use it to boost power.
Regenerative braking also recovers some energy to recharge the battery.

Williams are testing a flywheel kinetic energy recovery system - the device that stores energy under braking - and have set up a company to develop the technology both for Formula One and further applications outside the sport.
Supercapacitors have a big internal surface-area that allows a large amount of energy to be delivered rapidly and are used in some electric cars to provide a short burst of power for rapid acceleration and in hybrids to recover energy during braking.
Dubbed KERS, for Kinetic Energy Recovery System, the powerplant designed to recapture energy lost during braking or coasting.
The paddles also give the driver control of regenerative braking, which translates the kinetic energy that is dissipated when the car slows down into electricity that tops up the batteries.
ECONOMIST: Fast cars will go even faster with electric power
Its two high-speed electric motors operate as one but can act independently (and incidentally, by using reverse torque instead of friction for braking, the motors convert the energy of your motion to help replenish the battery).
During braking, it becomes a generator, recapturing energy normally lost as frictional heat.
Kers stores energy that would normally be lost during braking and converts it into power.
This novelty harnesses energy that would have been lost during braking and allows the driver to reapply it during acceleration.
Kers stores energy that would normally be lost during braking and converts it into power that drivers can then use.
This is somewhat akin to capturing the kinetic energy of an electric car via regenerative braking a feature found in the Toyota Prius.
The new developments include a switch to slick tyres from the grooved ones of recent years, and the introduction of the kinetic energy recovery system (Kers), which stores energy recovered from the rear axle during braking and converts it to supply a brief power boost.
They include changes to the aerodynamics, the re-introduction of slick, untreaded tyres after 11 years with grooved rubber and the potential use of a kinetic energy recovery system (Kers), which stores energy that would have been dissipated during braking and reapplies it while the car is accelerating.
The Kers system stores energy that would otherwise be wasted as heat during braking, then reapplies it during acceleration to provide a boost in power, controlled from the cockpit by the driver.
"The Nissan LEAF has an advantage in that braking force is used to re-power the battery, thereby improving its energy efficiency, " said Castignetti.
