Plug-in hybrids only achieve their maximum emissions benefit when they are actually plugged in daily, and that isn't happening as often as regulators who set emissions rules assume, according to a new study from the International Council on Clean Transportation (ICCT).

Using telematics, NYC Fleet, part of New York City’s Department of Citywide Administrative Services (DCAS), recently analyzed actual fuel economy in its hybrid and non-hybrid vehicles and compared it to the EPA ratings for each make and model. hybrids are even more fuel efficient as compared to regular fuel vehicles than expected.

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).

The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. The OSU EcoCAR PHEV powertrain. The effects of the added weight have also been explored, showing very minor penalties on the fuel economy and all-electric range at urban conditions.

GHG emissions in PHEV post-transmission configuration as an example of the optimization study output. Broadly, he found that for the PHEV pre-transmission configuration, there is a trade-off between fuel economy and GHG emissions when the motor/generator and battery size increases. Source: A.A.

l/100 km) in 2016, the The ICCT team assessed increased consumer label fuel economy (as opposed to the regulatory test fuel economy) to 35 mpg (6.71 The resulting trajectory would reduce CO 2 emissions by half and increase fuel economy by more than 60% from 2016 through 2030.

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.
