I am predicting

USMCASA · 01-04-2011, 05:53 PM

just wondering if anyone has any valid numbers to back up either side. i just always heard an auto wastes hp and a manual delivers more.

Vegitto-kun · 01-04-2011, 06:30 PM

well as far as I can tell it has been dyno proven that the AT loses more HP than the MT but for some reason (shifting speed?) it is abit faster

I'd say auto's faster in the aspect that to launch the car you kick up the RPM anywhere from 1500-1800 and get off the brake and let it rip, i do 13.35 @105 mph constant doing that, with crappy street tires. The manual takes a lot more skill to get a good launch of the line.

The ratios and final drive ratio for auto and manual are entirely different, which may explain some of the difference. The 7AT is geared lower which means you have to shift sooner, so it loses effective torque while accelerating earlier than the 6MT but it puts more torque down which seems to balance it out.

1st gear is short and second gear is extremely short in the 7AT - you stay in it for 19MPH versus 26MPH for the 6MT, then the 7AT gears are longer.
(6MT: 41/26/28/27/39 - 7AT: 36/19/31/39/51)

I don't believe dyno tests show a significant difference between the two - 370z.com Magazine shows 7AT stock at 267hp / 220 ft-lb versus a 6MT stock at 262hp / 210 ft-lb (different days, same dyno), so the 7AT really gives up nothing at the wheels either.

No, what it gives up is the satisfaction of driving the car.

In automatic, car drive you!

********. it is just something those MT freaks say.

a regular slushbox where you just put it in D aaand thats it yet.

but you cant say that about a flappy pedal/stick shift thingy AT.

You're right, feathering the clutch with those paddle-shift...oh wait. There is no clutch. There's an old viscous coupling known as a torque converter. Pass.
