This morning's drive to work was great. The cooler air was definitely noticeable - throttle response was better, and the car accelerated more easily.

As the temperatures drop, don't forget to check your tire pressures. I've read that each 10 degree drop in temperature reduces your tire pressure by 1 psi.

Don't have to worry about it if you have nitrogen in your tires! :D

Yep, car is loving the weather. Screwed up my errand running this weekend as I just decided to barnstorm instead... :D

I'd like to get the first frost/freeze on already to kill of the dumb bugs...

But yes, fall is great driving (Motoring!) weather. :buttrock

My Audi S4 felt like it had 50 extra hp when the temps got below 50. Nothing like cold air for a turbocharger.

It still happens with N2 in your tires, the swings just aren't as large as with normal air.

The ideal gas law still holds - PV = nRT

Decrease T, P will decrease as well.

If your a member of COSTCO you get free nitrogen refills in your tires. It doesn't matter if you bought tires from there or not.
