NREL study finds gasoline hybrid delivery trucks substantially reduce emissions and beat or maintain fuel economy compared to diesel vehicles

Green Car Congress

NREL’s Fleet Test and Evaluation Team recently completed a year-long technology evaluation of gasoline hybrid electric (gHEV) FedEx Express delivery trucks compared with conventional diesel vehicles. On a drive cycle representing routes with frequent stops and accelerations, the gHEV trucks exhibited a 20% improvement in fuel economy.

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. The 2016 RAV4 also debuts new technologies to bolster convenience, entertainment and information.

Interim NREL Report on In-Use Azure Balance Gasoline Hybrids in FedEx Fleet Finds Substantially Lower Tailpipe Emissions, Similar Fuel Economy to Diesels

Green Car Congress

Fuel economy was similar between the gHEVs and diesel vehicles, except for the highest kinetic intensity drive cycle where the hybrid exhibited ~20% higher fuel economy. NREL collected and analyzed data for in-use fuel economy and fuel costs, maintenance costs, total operating costs, and vehicle uptime. Ah NimH battery pack.

Hyundai Debuts Sonata Hybrid at New York Show

Green Car Congress

Unlike traditional [power-split] hybrids that trade off highway fuel economy for higher city ratings, the Sonata Hybrid delivers best-in-class highway fuel economy, while still delivering about a 40 percent improvement in city fuel economy compared to a Sonata equipped with the Theta II GDI engine. The Sonata Hybrid.

UC Davis Researchers Suggest the Battery Problem Seen to Be Slowing Electric Drive Commercialization Is Perceptual as Well as Technological

Green Car Congress

We contend that potential solutions to the battery problem are not just a matter of technology development and cost reduction, but instead involve a concurrence between battery technology and appropriate PHEV performance goals. They note that other requirements may make NiMH unsuitable for PHEV applications. Source: Axsen et al.
