Not quite, but it definitely could if the technology could get some funding to advance it. The batteries, chargers, and electric motors still waste a ton of energy that needs to be considered for overall efficiency. But it usually gets overlooked because it’s harder to quantify without access to a lot of proprietary data.

If we’re talking only moving the car and in optimal weather (EVs have a significant disadvantage in the cold), the combustion engine is still significantly more efficient at creating the kinetic energy from raw oil than an EV from any type of power plant’s fuel. You have to consider all the stuff that happens before the gasoline or electricity gets to the car as well as idle waste. Gasoline in a proper tank evaporates much more slowly than idle batteries lose energy.

If we’re looking at air conditioning and other electrical stuff, the engine and alternator system is probably not quite as efficient at charging the battery as the power grid and EV chargers are. It’s at least closer.

But more efficient batteries and chargers (especially the fast chargers) would probably close the gap. But not likely to happen until the oil industry collapses so the tech gets some real funding. One day it will get there. Combustion tech has no real way to improve efficiency without significantly sacrificing safety. But EVs have lots of room to improve.
