Automatic HP?

How much HP do you lose on the V6 with the automatic transmission?

None. Its only different on the V8 because they used AFM, which required different tuning. I think it involved a drop in CR and a different cam.

V6 is the same regardless of transmission choice, though.

That's the V8. Now, the auto IS a smidge slower than the manual, but that was expected.

Its not hard to learn. Took me a few hours to teach my Sister-in-law. After that its just practice. And you have to have a manual car to really do that anyway.

P.S. - And Mythic, it dyno's at 260 rwhp, and 240 rwtq.

At the crank it will be the same HP/TQ ... the manual and auto will differ at the rear wheels though because of different drivetrain losses.

Learning to drive stick is not that hard after the first few days. I remember kids in a front yard playing and laughing at me when I stalled in front of their house three times in a row my first day. but even after eight years of it I still stall once every few months or so. It's embarrassing, and The new reviews said that the clutch on this new Camaro is a lot quicker than on the mustang or challenger, so the reviewers actually stalled it themselves, even with all of their test-driving experience. If the clutch is really that bad, I might actually consider getting the automatic, if I get v6.

Also, don't get manual if you live in a place with a lot of hills, you will roll back when shifting into first from a stop. If someone stupid pulls in too close behind you, you will have a hard time not hitting them.

Only if you're stupid enough to put your foot on the brake. You can hold the car without moving using on the clutch (and maybe the gas if its a REALLY steep hill) at which point you can launch without rolling. Honestly, if you stall still and roll back at hills, I have a hard time you've been driving stick for eight years. Unless you're talking like, once a year for eight years.

The manual has more aggressive gearing which will make it a bit quicker. And it is also going to have lower losses meaning that it will put a few more ponies to the ground than the auto will.

Sometimes i roll back on hills but no more than maybe an inch. Once you been driving your car for a while you know exactly when your clutch engages allowing you to engage the clutch quicker without rolling back or stalling it? Sometimes i hold my clutch on hills to prevent me from rolling back, it all depends on how steep the hill is.

But honestly, the v6's aren't for performance. Really if you decide to get the manual, you will find that switching the gears is pointless in the v6 considering the auto and manual are almost exact. Especially if it is used for a daily drive. Now the v8 is where it will matter.

I would chose to get the manual in the v6 only to save an extra $1600 for the vehicle. Besides your suppose to drive slow and smooth in the camaro to make jaws drop, heads turn and to make people wonder who's driven that amazing car!!!!

Plus you dont want the women that you will pick up to jerk their heads everytime you switch a gear.

Although the torque at the crank would be the same I wouldnt be surprised if there is a small loss at rear wheel HP. Autos use a torque converter> the TC uses friction from the fluid against the fins to drive the tranny. There is heat loss which equals power loss equals less hp at the wheels.

But automatics produce more torque from the raw engine power via it's hydraulics. (Torque converter).

Ehh..

A6 in the V8: 4.6
M6 in the V8: 4.7

Granted in the quarter, you've got me, but a quick run from the light and we are dead even. And im cruising in a jerk-free, stall-free, higher MPG, traffic friendly vehicle, where i can spend my time focusing on traffic and cops while you're watching RPM's. I win. You lose.

I'm thinking the MAIN REASON the MT is quicker than the AT is the MT comes with a Limited-Slip-Differential and the AT has a plain old open differential ... I.E. you'll experience major "one wheel peel" with traction control off.

Gearing and HP losses can be part of the equation, but in most instances today's automatic equipped performance cars are quicker than the manuals.

Sounds like a boring drive, actually. Your definition of "win" may not be how everybody else feels.

The average power loss through the transmission is about 15%, and about 12% loss through a T6060

Driving about a hundo on the (heavily trafficked I-35) interstate is never boring, good sir. But you have a valid point and I agree.

I don't know how hilly OK is, but if you drive that way around here (Seattle) you're going to be going through clutches pretty fast.

Yeh, but when your in your daily commute with your AT and the car right in front of you needs to go 2 MPH faster so your Auto kicks in O.D. you'll be wishin' you had control of the gears. I guess with the paddles, maybe you can force it in O.D. & dog it down a bit, don't know for sure.

Drove a '02 Cavalier most of last summer and for it to kick into O.D. I had to be going around 42 MPH ... so 7 over being usually safe, I always went 42 in 35 zones when I could. Drove me nuts sometimes I'd get behind someone doing 40 ... come on just speed it up 2 MPH !! When dropping speed, it would shift out of O.D. at around 40, so it's not like you could get it in at 42 then drop your speed and hold O.D. either. Car was rated for 32 MPG hwy and I actually got 32-33 MPG with only 60-70% on interstate w/ cruise set @ 75 MPH.

My normal daily driver is an '04 3.9 V6 Mustang w/ 5-Speed and I dog O.D. down to around 1000 RPM / 33 MPH all the time in traffic. The '10 V6 Camaro w/ MT will be running 1000 RPM in O.D. @ 34 MPH so I should be able to drive very similarly with it. If the EPA testers drove like me, the MT would get better City MPG than the AT.

Just wish they would make 4th 1:1 ratio (instead of 5th) and give us 2 overdrives like they used to with the old 4th Gen Camaro 6 Spd. When your out doing 75 MPH (2229 RPM), it would be nice to drop it below 2000 RPM to possibly save even more fuel. My 1st 3.8L 5-Spd Mustang was a '94 it had highway gears ... O.D. @ 60 MPH = 1617 RPM / 75 = 2022 RPM. This '94 was 145HP@4000RPM / 215ft/lb@2500RPM, I'm sure the much more powerfull Camaro V6 engine could cruise at lower RPM's than this car could.

Sorry to get this so far off topic !!

Doug

Still got the blinker and gas pedal combo, the brakes, or a little love tap on the horn. Itl be fine.
