Why do cars with automatic transmissions have tachometers 2604

Now that is an authoritative sounding but truly misleading statement. Since the power or torque curve is just that...a curve that begins at zero, any time the transmission shifts above zero it will be someplace in the power band. Its a question of where on the curve you want to shift. In addition to controlling quickly you can accelerate, the place you select on the curve will also govern how much fuel you burn and how much wear and stress you place on the engine. You appear to have little concern about fuel economy and engine longevity - playing the race driver seems to be your focus.

I have yet to experience that in hundreds of thousands of miles driving four cars equipped with automatic transmissions.

Interesting but rather bizarre statement that is not supported by the real world of driving that I've encountered. I drove numerous stick shifts before switching to an automatic several cars ago. The electronically controlled automatic of today does a far better job of shifting than most drivers I've encountered. Most guys with manual shift transmissions seem to like keeping the engine in a lower gear than needed presumably for the imagined race car thrills from hearing the engine at 4,000 rpm.

Well, my feelings on this subject are mixed. Your Otto Cycle engine in your auto-tranny equipped vehicle will be most fuel-efficient in the powerband...

Whee...look everyone...I'm a race car driver 'cause I got me a car with a five speed, tach, spoiler and noisy exhausts to prove it.

Yes, there are workarounds, but driving a

A lushbox...??? A box full of alchoholics maybe????
