Hi:

I have been an manual transmission driver all of my life. With the G35, I am wondering if I should have bought the Auto. The VQ motor is so smooth and fast as it revs that it is very easy to exceed redline before up shifting. (I have "floored" it only once to date and don't make a pratice of fast take offs.) It will take me a lot more pratice to learn up shifting correctly. Having an auto transmission might save me from this.

G35Gnome, I'm surprised your Pilots spin so much. Are you sure they're not overinflated? The dealer delivered my G with RSAs pumped up in the mid 40s. I take the rears down to 27 or so (I think the manual recommends 32 for normal driving). Tire pressure isn't as important with street tires, but it can still screw you up if you have it badly over or under inflated.

If you want the pimped out Brembo calipers ... =P Jk ..
AT vs MT should be a preference of wht you want to drive.
lol @ Trenta .. No stock MT will beat a AT by 3 car lengths...
Remember the "security device" called the 6MT .. Haha. I'm a pretty new driver so I bet stock AT's could beat me.

Do the math people. 3 tenths in a 1/4 mile @ approx. 100mph is about 3 car lengths. I'm no computer genius but I figured that one out.

we are not trying to start another flame wars b/w AT and MT... and yes your are very correct .3sec= about 3carlength at 1/4 speed... but the question is, how many MT will be able to pull 3carlengths everytime when they race AT owners? i think not that many... it's not right to compare best MT vs best AT(i think best AT was 14flat which MT must run 13.7 or better but didn't seen one yet)... i think it should be fair to compare average time MT vs avg AT cuz people can't run best time most of times... if you averaged up, MT won't hold .3sec faster than AT but less...if i did math correctly, AT should runs around 14.4-5... i don't think average MT time will be 14.2 or better(according to MT is faster by .3sec)but around 14.4-5 also(i don't know actual average since driver skill is very important but i assuming you drive better than good level)... no flame war intended... just my thought...

Guys, come on. 0.3 seconds equals 1.9 car lengths only if one car is going 100 mph and the other car has abruptly slammed into a brick wall (i.e. it's going 0 mph). Then, yes, the car going 100 travels 528 inches further in that 0.3 seconds. But the G is 182.2 inches long, so it's not even 1 full car length behind until the other car has moved twice that distance, because they line up nose to nose.

In reality, one car is going around 100 and the other around 97-98. But it's not as simple as just doing the same math with 3 mph instead of 100 mph, because you have to figure that the faster car was going 1 or 2 mph faster during the course of the entire race. Which is where my math expertise ends, so someone else will have to pick this up.

But it's certainly not 3 car lengths.

I'll take my auto over my 14 years of manual skills and be happy as hell - got my #7 wire beaaaatch

 

Ok. Time to break out the math. For the purposes of the comparison, assume the following:

(1) the 5AT has a maximum velocity of 98 mph when it reaches the 1/4 mile mark.

(2) the perfectly-shifted 6MT 1/4 mile time is 0.3 seconds faster than that of the 5AT.

Based on a top speed of 98 mph and a 1/4 mile time that is 0.3 seconds slower than the 6MT, that means we have 0.3 seconds to go at 98mph to reach the finish line.

So, 98mph = 143.73 feet per second, multiplied by 0.3 seconds and you get: 43 feet.

The 5AT is 43 feet behind the 6MT when the 6MT crosses the finish line.

That's basically what I was trying to say.

I wasn't trying to sling mud. When I said you'd be seeing the license plate it was in jest. In daily driving you're not going to see that .3 seconds and in 0-60 you're looking at less than a car length I bet.

I totally agree that you won't be able to perfectly shift on consecutive runs. And you also have to worry about the launch.

The surprising thing is that a 6MT sedan will run pretty dam even with a 6MT coupe. Not so surprising as much as impressive.

Shifting perfect is VERY EASY... The hard part is the launch.. There is a lot of variables that can change the way you launch.. For this car it is very hard to launch with the stock suspension and tires.. Spinning most of first is usual along with when you shift into second breaking loose.. As for a auto simply hold break rev to 1200k and mash the pedal... Plain and simple.. So with the manual its all in the launch..

Bahhh I did 2x 99mph and once 100mph today at etown, check the sig. Time to recalculate the math. But yes it is easier to launch an auto than stick, thats for sure. Ahh yea I did all of my runs today in MM mode shifting a bit past redline. I did one terrible run today(the first) but forgot to turn my vcd off so I dont count that one

here are 3 runs for your guys comparison

1. 14.375@99.38, 2.389 60ft
2. 14.456@99.00, 2.304 60ft (this one I hit redline and got a cut off shifting into 3rd)
3. 14.371@100.29, 2.347 60 ft

Thats with launching between 1200 and 1500rpm, last run was with rear tire pressure at 31psi

Just a clarafication guys, the runs I did were with the mods I have, not stock. I lost some time at the launch because of the tire spin and probably gained some at high rpms because of the crawford and borla. So I think my best run was what you would be getting with a stock AT. But anyway all this talk and calculation aint worth s***. The only true numbers that matter are those on the slip at the track. And the best I have seen any G run is 14 flat(AT).

That is the bottom line.

 

Zimbo,
since you are good at math can you figure how many quarter miles my five speed auto can cover in three minutes at his speed???it's about 145 MPH just to round off the numbers.

Me! Me! Me! (hand in the air, waving franticly) .... I got the answer ............ its 29 quarter miles Do i get a cookie ?!?!
