It's gonna make some difference, but air resistance goes with square of speed and the change in density due to temperature isn't that large.

It’s about -3% change in drag force per +10°C change in temp.

Which is like the same as 60 mph vs 59 mph.

In drag force, yes, but in this case, you are taking the 3% penalty and aren't getting the partially offsetting 1.7% increase in distance per unit time that 60 gives you over 59.

Note that it's 3% per 10°C delta so, for a 40°C swing (say 30°C/86°F summer to -10°C/14°F winter), that's a 12% difference in aero drag force.

Which is basically nothing.

Opening your window makes far more of a difference.
