The traction battery can be charged from the electric power grid or while driving. When they are closed they improve aerodynamics, which reduces air drag and thereby improves fuel economy. This enables driving performance on the level of a sports car: zero to 62 mph in 5.4 seconds and a top speed of 243 km/h (151 mph).

US National Research Council Report Finds Plug-in Hybrid Costs Likely to Remain High; Fleet Fuel Consumption and Carbon Emissions Benefits Will Be Modest for Decades

Green Car Congress

NRC projections of number of PHEVs in the US light-duty fleet. Costs of light-duty plug-in hybrid electric vehicles (PHEVs) are high—largely due to their lithium-ion batteries—and unlikely to drastically decrease in the near future, according to a new report from the National Research Council (NRC).

EV myths busted: Are electric vehicles actually good for the environment?

Drive Electric

ICEVs have been around for a while, and although they’ve had the time to perfect their manufacturing process and we’ve seen increased pressure on the importance of fuel economy and emissions, the thermal efficiency of the average light vehicle engine remains between 20-35%, and we’re not seeing much improvement beyond this.
