I got a manual because I don't really know how to drive an automatic.

While it's certainly easier to drive an auto stop and go with the P5 you will pay for it through the nose in terms of MPG. The P5 Auto gives piss poor mileage in that sort of usage, at least mine does, about 21 mpg. The manuals are reported to do considerably better, like 25-27 mpg. (Search the P5 threads). Probably this is because in stop and go driving the torque converter in the auto is never locked, and most of the time, not even close to locked, so way too much of the gas being used is going into churning fluid and not moving the car down the road. Also when I used to drive a manual in stop in go it was actually in neutral a lot of the time when moving. You know, pump in a little energy, get up to 15 mph, and then coast. In the auto it pretty much stays in gear all the time.

Remember that the auto is only a 4 speed. My P5 (my wife's car) has an auto trans. At highway speed (70-75) the engine is revving pretty high for my taste. IIRC, it's around 3k RPM or higher.Lord_Zath said:interesting. I always figured manuals had worse mpg since most people take their car above 3k rpms, and autos usually shift around there.
BWAHAHAHAHA! Nice! I had to learn to drive an automatic when I came home No manual cars ftlSilverBulletES said:I got a manual because I don't really know how to drive an automatic.
if i didn't have an automagic, how else could i smoke, drink coffee, make my daily stock trades, and shave on the way to work?
