In theory, yes. In practice, it doesn't work that way. Compare the
efficiency of a car engine with the efficiency of an electric car

I'd be surprised if it works out that way. IC vehicle engines spend a
lot of time running at very low or zero efficiency in slow-moving or
stationary traffic. I've no idea what the overall real-world efficiency
of IC-engined vehicles actually is, but (guessing) I'd doubt it's more
than 20%.

Electric vehicles should win hands-down, as the standing losses are so
much less, and the power conversion efficiency through the inverter and
motors should be quite high (80%?). A modern combined-cycle gas-fired
power station approaches 50% thermal efficiency. AIUI electricity
distribution losses are 10-15%, so the overall efficiency is over 40%.
Now what's the overall efficiency of the battery charge-discharge cycle?
If it's higher than 60% (as surely it should be) then the electric
vehicle probably wins (YMMV).
