The 2014 Accord Plug-in has been rated by the EPA with a maximum all-electric EV mode range of 13 miles (21 km) (Honda had earlier projected 10 to 15 miles), and a fuel-economy rating of 47/46/46 mpg city/hwy/combined (5.0/5.1/5.1 Electric driving is supported by a 6.7 l/100km respectively). This corresponds to US EPA Tier 2 Bin 2.).
LDV energy consumption declines in AEO2014 Reference case from 16.0 quadrillion Btu in 2040 in the AEO2013 Reference case. The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case.

The regulation establishes two performance standards that fuel producers and importers must meet each year beginning in 2011. One standard is established for gasoline and the alternative fuels that can replace it.
The Annual Energy Outlook 2011 (AEO2011) Reference case released yesterday by the US Energy Information Administration (EIA) more than doubles the technically recoverable US shale gas resources assumed in AEO2010 and added new shale oil resources. Beyond 2020, CAFE standards for both passenger cars and light-duty trucks are held constant.

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. 35% (PFI baseline).
A CNG vehicle reduces CO 2 emissions by about 25% compared to a gasoline-driven equivalent. Only a pure electric vehicle running on 100% renewable energy would offer a better overall outcome. But even in the event of using the gasoline tank, the switch is so seamless that the driver is unlikely to notice.

In spite of increasing electric mobility in the transport sector, we will continue to need liquid fuels for a long time. When talking about phasing out of combustion engines, it is referred to car engines only. According to these scenarios, gasoline will disappear from the market first, Dahmen points out.
