not really, keep in mind that electric cars are able to recover energy from breaking, while traditional convert that to waste heat, that should tip average efficiency by dozen of percent points. That's also from where mild hybrids have better efficiency.
for heating heat pumps have it's average yearly efficiency about 300-500% (depending on climate) so when we use the same fuel to just make energy at with that 40% you mentioned, we end up with overall efficiency well over 100%
so in both cases it's better to burn the same fuel to create electricity than to use it directly
