Honda product automatics historically tend to have a bigger difference in accelleration vs the manual than other mfgs........Preludes, TL's etc tend to accellerate alot better with the manual, where as with other mfgs the difference is not as much.

It's not just the 15 whp difference, but also the 100 lb weight penalty for the 5AT (which makes the static difference more like 25 whp) and the overall better gearing and efficiency of the manual which in the end accounts for the ~5 mph trap speed advantage.

Do the math. The TL has a much better lbs/HP ratio than the G35 FOR THAT YEAR.

Now, throw in the variables: load weight, driver skills, etc. and it makes for an interesting contest.

It would be a lot closer than you guys seem to think. They are both autos so all the talk and times about MTs is just clouding the issue.

True but there are a few key things in the G's favor.....Better/more agressive gearing auto to auto, more torque and it being all wheel drive it can launch more aggresively than fwd TL. TL's advantage is less weight.

Yep, you beat me to it Monte.

Is it even really much of a challenge to launch a 5AT base? I thought they just spun for a few feet, then went.

Weight Shift: Suppose you just want to go in a straight line. What's the best way to get traction? Answer: Have as much weight over the driving wheels as possible. Front-drive cars start with an advantage -- but when any car accelerates, the front end tips up, and the rear end squats down. This transfers weight to the rear wheels -- away from the driving wheels in a FWD car but toward the driving wheels in a rear-drive car, where it adds to available traction. In effect, the laws of physics conspire to give RWD/AWD cars alot more grip where they need it when they need it. This salutary effect is more than canceled out against a RWD auto in slippery, wet conditions, where you aren't going to stomp on the accelerator. Then, FWD cars have the edge, in part, because they start out with so much more of their weight over both the driving and the turning wheels.

LOL, no offense, but I wasn't looking for a tutorial on RWD vs FWD vs AWD physics. I've owned at least one in each configuration, and with the exception of two trucks, every car I've owned in the last twenty years has made at least one pass down the dragstrip. I understand traction or lack thereof.

What I was getting at, was I thought the base 5AT just pretty much hooked and went, with minimal drama, basically eliminating any bias derived from driver skill. I had a loaner 5AT for a few days, and it was noticably slower on the highway, but I never tried any standing launches in it.

No offense guy, hard to offend me especially on such minor meaningless stuff!

Here's my take:

1) The "260hp" 03/04 sedans make the same power to the wheels as the 280hp 03/04 coupe and 05/06 5AT sedans. It was merely a marketing ploy by Nissan. When the new SAE power ratings came out, the 280hp motors were rerated to 275hp.

2) C&D got a high 14.4@96mph out of a 2005 G35X sedan in an AWD sedan test back in 2005.

3) On G35driver, there way more stock X's in the 14s than in the 15s. 14.5 is best I've seen, 14.7-14.8 is more typical.

4) The 03/06 X weighs about 3,580 to 3,650lbs, depending on year.

5) The AWD system is heavily RWD biased and above 20mph or so and no slippage is occuring, the system is a 5/95 split.

6) The X has the axle ratio gearing from the 6MT cars to improve acceleration due to the 185lb weight increase from the AWD system. Overall, gearing is about 10% deeper.

7) The power difference between the X and RWD autos is minimal because most of the power to diverted to the rear. The acceleration difference in the 1/4 mile is about .1 seconds and 1 to 2mph.


IMO, the X should win pretty easily. Right from the start, it should take right off. Most 5AT TLs see 2.4 60 foots. An X typically sees high 2.1s to low 2.2s. The gearing in the X is far deeper therefore the acceleration advantage from 0 to 70mph will strongly favor the X. Only from a 60mph+ roll do I think the 5AT TL may stand a remote chance.

Sure, they hook up, but they're geared too long, have a tight torque converter, and minimal low end torque. This results in minimal spin, but also minimal acceleration from 0 to 50mph.

He said they are gonna race from a roll. That makes AWD a huge disadvantage and as long as they dont race through 4th gear the gearing isn't too much of an issue. I'm not fully bolted and I'm 5at and I beat stock G35s(nonHR, I havent raced any of those)...

AtlM5

From what I've seen, thats a pretty high trap speed for the 1/8mile. Atleast for that ET it is, isn't it?

so i never get to race that g35 but i raced different one it was 08 sedan 6spd awd with some mods, he had 3ppl in it, from a 40 roll till 120 had like 2 cars length all the time but from dig he got me like fender but i was catching up to him and i was recording with one hand ill post the vid later on even know it was crappy phone camera
