XL launches PHEV Ford F-250; 50% improvement in fuel economy

Green Car Congress

The battery is also charged by regenerative braking during driving, which captures and stores energy while slowing the vehicle. The energy is then transferred back into the drivetrain through an electric motor which helps propel the vehicle during acceleration, reducing fuel consumption, CO 2 emissions and brake wear.

Toyota announces expected fuel economy and pricing for RAV4 Hybrid: 33 mpg combined, entry at $28,370

Green Car Congress

Regenerative braking changes the electric motor to a generator that captures the kinetic energy of the still-turning wheels when the brake is applied, storing it in the nickel-metal hydride (NiMH) hybrid battery pack. In EV mode, the RAV4 Hybrid, under certain conditions, will run solely on the electric motor for up to 0.6

Lightning Hybrids and National Fleet Hybrids partner on hydraulic hybrid retrofits

Green Car Congress

Hydraulic pumps and a lightweight accumulator store braking energy and upon acceleration the pumps become motors that use the stored energy in the accumulator to provide torque to power the wheels. The Lightning Hybrids applies a hydraulic drive system to the driveline of a vehicle to regenerate braking energy.

DOE issues request for information on medium- and heavy-duty fuel cell electric truck targets

Green Car Congress

FCTO set fuel economy targets for each weight class to reduce the confusion of one normalized target that would span all weight classes. Lifetime targets and maintenance costs suggested are based on fuel cell bus targets. Proposed targets for the fuel cell trucks are: Proposed Fuel Economy Target (miles/kg H 2 ) for 2025.

J.D. Power survey finds China consumers increasingly enthusiastic about new-energy vehicles; ongoing importance of subsidies; battery worries

Green Car Congress

Environmentally friendly (76%) and fuel economy (63%) are the most often cited reasons for purchasing an NEV, while government incentives, such as subsidies (61%) and free license plates (40%), are also important. Seven in 10 (68%) consumers are concerned that the mileage driven on one charge will decrease over time.

Ricardo TorqStor flywheel energy storage technology receives SAE 2014 World Congress Tech Award

Green Car Congress

The TorqStor is an advanced flywheel energy storage system, storing energy that would otherwise be wasted through parasitic losses or braking, and returning that energy to the drivetrain when needed, providing improved fuel economy. Ricardo’s TorqStor. Click to enlarge.
