HP to wheels

[Sailorted53]

Anyone know what is the total horsepower transmitted to the wheels on a 2.5L/ AT ? Published 184 hp (bhp) is likely the engine-only output as it sits on a dynamometer. (?) I see other auto manufacturers with this HP at wheels number quoted, but I've never seen it for Mazda products. Would love to see a comparison of AT vs. MT.

AT with most every car is slower than MT(mainstream cars) the first gen 2.3L 3 AT has a 0-60 time of 8.5 seconds the MT can do the same in just a tick over 7 (i have one and timed it myself, and road and track or car and driver had that listed as their time as well (about 7.2 seconds 0-60 stock) mine with some very light mods can get right under the 7 second tick to 60 which is not bad for a n/a 4 cylinder. id venture to say the engine power of my car being almost 160hp (156) gets about 139-145 to the wheels in MT trim(as it can coast for a long time) so very low resistance drive line and maybe 130-135ish through the heavier and more apathetic AT. (stock) granted mine has about 163hp at engine now so i may get some more at wheels but a negligible amount, however its enough to notice when i wanna get up and go. id venture to say a 2.5 skyactiv AT puts maybe 150-160ish to the ground (never driven the automatic with that engine) and MT puts maybe 160-165ish but i am taking figures that i see from other cars and from previous expereince knowing my protege lost about 17hp through the driveline stock, i have not taken a 3 on a dyno to test it.

Remember that regardless of how much power it puts down, chopping rotational mass can improve acceleration times. I dropped almost 10 lbs per wheel when I got rid of the anchor-like factory wheels.
I wouldn't easily doubt that my auto 2.5 is faster than a manual 2.5 that has the factory 18-inch wheels on it.

concept i bet it would be close. in your case dropping 10 pounds per wheel is drastic and dropping 1 pound in wheel weight in all 4 wheels is equivalent to dropping 100 pounds off the car as a whole. this usually has more to do with cornering and handling ability but any unsprung weight taken off the car will have a good impact overall. losing 10 pounds per wheel probably puts yours right with a manual with same motor if not a just a scoshe ahead of it in speed if the manual were 100% stock. we would need a stock 2014 2.5 manual sedan and a straightaway long enough to get them going to see. or we would need a dyno and a bunch of math. either way option one sounds more fun.

KMS,
It does make a seat-of-the-pants difference when accelerating briskly, that's for certain.
I've had both a manual and auto transmission pair of (various) cars since 1980. The result is that it takes much more time before I get bored with either vehicle.
