Electric cars perform less well in cold weather. Lower ambient temperatures affect an EV’s range, but also how quickly the battery charges and how effective its regenerative braking system works.
In a gasoline-powered car, turning on the heater hardly impacts fuel economy at all. That’s because gas engines make lots of heat all the time, in summer and winter.
Electric cars also have impacts arising from the manufacturing of the vehicle. [43] [44] Electric cars can utilize two types of motors: permanent magnet motors (like the one found in the Mercedes EQA), and induction motors (like the one found on the Tesla Model 3). Induction motors do not use magnets, but permanent magnet motors do.
The environmental impact of fuel cell vehicles depends on the primary energy with which the hydrogen was produced. Fuel cell vehicles are only environmentally benign when the hydrogen was produced with renewable energy. [127] If this is the case fuel cell cars may be cleaner and more efficient than fossil fuel cars.

Some vehicles, such as the 1992 and 1993 Fox-body Mustangs, do use such as a system even though they have multi-port fuel injection, presumably to help the air-fuel mixture burn at the proper rate in cold weather, as even though the fuel has finely atomized, it has not properly vaporized, and therefore flame propagation will be otherwise slower.
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, [1] 2016, [2] 2017, [3] and 2023 [4] versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid ...
The following table compares EPA's estimated out-of-pocket fuel costs and fuel economy ratings of serial production plug-in hybrid electric vehicles rated by EPA as of January 2017 expressed in miles per gallon gasoline equivalent (mpg-e), [1] [2] versus the most fuel efficient gasoline-electric hybrid car, the 2016 Toyota Prius Eco (fourth generation), rated 56 mpg ‑US (4.2 L/100 km; 67 mpg ...
