Is there really that big of a difference between MT & AT!?
I REMOVED mine and filled the compartments with sharpened railroad spikes to ensure thorough impailment in a crash.
Then to save weight I sanded all the paint off my car and I only allow an eighth of a gallon of gas in my tank at any given time.

I've owned both 5AT and 6MT G35's. One is not better than the other, it just comes down to whether or not you want to row your own gears. Lots of high school kids and douchebags in the US like to stroke their ego about driving stick even though it's a basic skill that 100% of drivers in other countries know how to do and takes about one day to learn. As far as performance goes, I'm sure the macho 6MT crowd here is burning up the strip in their 298hp 3500lb touring cars.
Don't regret your purchase, and most of all don't let somebody else dictate your needs and wants when it comes to purchasing a vehicle.

It's not even that difficult.. I learned in a parking lot in 10 minutes with the first manual car I ever bought (PreludeSH).
I totally support people preferring MT over AT because they find in more enjoyable to drive. But preferring it because it makes you feel superior is another thing.
But then even if I had an AT G35, I'd still love it, cuz it's a G!
Your exactly right but the a/t has about 10 more ftpn of trq. 270 versus 260 for m/t. Torque is what get's you going at 4200 rpms and then the hp kicks in at around 5400 rpms. That's why theses cars are so close in performance. The a/t should have an edge on take off and the m/t cathing up on the top winning by about 2 tenths of a second..
For the 2007 models the 5 A/T is rated at 275 hp @ 6200 rpm / 270 lb-ft @ 4800 rpm with a curb weight of 3,505 pnds and maximun engine speed of 6,600 rpm. The 6 M/T is rated at 293 hp @ 6400 rpms and 260 lb-ft @ 4,800 rpm with a maximum engine speed of 7,000 rpm and curb weight of 3,524 pnds. So that's 18 more hp more for the 6 M/T but 10 lb-ft less than the 5 A/T so these cars are going to be head to head in a race. Driver error will be the desiding factors. But there is another plus for the A/T coupe, it has a larger cabin than the 6 M/T. Head room is 39.2 vs 34.7, shoulder room is 53.7 vs 52.7, hip room is 53.6 vs 48.0, and leg room is 43.8 vs 31.4. To me that means a lot if your car is a daily driver and your driving a long distance to work everyday or go on frequent vacations.
I drove a 5MT BMW 325i before I got my G, which is a 5AT. Driving stick is a lot of fun and while I do miss it, it's nice in it's own way. Theres no doubt both stick and auto G's are quick, the differences are pretty small in shorter races. Like all have said, most can't drive stick worth a damn so many times the autos will actually win.
I like being lazy and saving gas since NJ has horrible traffic, and G's already get crappy enough milage around town. But I still kinda regret not getting a 6MT just for the fun of it...
Tiptronic is decent and you can control the car the same way as a manual car, besides about a half second of lag. I know its not the same but its closer than I imagined. Much more responsive in the G than the tiptronic in my mom's 525i

Ok, to the person that tried to call it "semantics" when outlining and recognizing there is a DIFFERENCE between a dual clutch gearbox (like a DSG or DCT or PDK) and a regular old torque-converter automatic is a complete idiot. I'm sorry, but it's not semantics.
There's a serious difference. Ones called an automated manual for a reason, and this is different from an automatic. The automatic is called an automatic because the torque transfer is automated by the hydraulic torque converter. It's physics.
For a DCT or SMG type gearbox the clutch is what controls torque transfer and while there is a computer system which "automates" it it's not automatic because if that computer system doesn't do it perfectly (which happens more often than you think) you as a driver (and your passengers) all feel the car jerk and buck just as if the driver messed up the clutch work.
There's a reason why they use dual clutches and not automatics in formula one.
The biggest defining differences is that on a torque converter the input side can never spin more than a couple thousand RPM above the output side. For a clutch the speed differences are endless (this is ignoring the fact that you'll fry your clutch doing 5000RPM launches daily, but I need to also mentioning that torque converters do wear when you launch your AT car).
Lastly, and this is the part I REALLY don't understand. A bunch of people always post crap on the forum that "looks cool" and gets a bunch of people to agree with them. Normally I wouldn't give a **** but usually the stuff they post is WRONG.
REALITY CHECK. Just because a bunch of people agreed with you DOESN'T MAKE YOU RIGHT.
Trying to claim it's "all the same" because the G is a heavy car with feeble horsepower ratings compared to $250,000 super cars is RETARDED. In our world of ever-growing-in-size automobiles, 3400-3500lbs is actually half decent...Even the new V8 M3 weighs 3550lbs.
Take it for what it is. Two identical cars, one with a 5AT and one with a 6MT, the 6MT is faster. It's really THAT simple.
There was no 7AT offered on a G35 coupe, so that's a non-issue right now, for all those people that brought it up like it was a huge triumph for the AT crowd.

And before some fool calls me an MT "fanboi" I will tell you I am not a fanboi of any type of transmission at all. If you look at the cars in my signature I have one MT, one SMG (single clutch, automated manual gearbox), one AT (the truck) and one CVT (the Prius). I've driven an M3 with a DCT, so I do know what it drives like and what the differences are vs my SMG M5.
That said, I'm the kind of person that chooses what I feel is the best transmission for the vehicle and the type of driving I will do with it. If I were to go buy an E92 M3 tomorrow, I'd buy a DCT, hands down. If I were to go buy a new G37 sedan, I'd get the 7AT. If I were going to go buy a 335i, I'd get the manual. So on, and so forth.
People who buy MT's just because it's an MT are idiots. My friend in fact did this. He bought a Jetta TDI and I told him to get the DSG but no, he got the manual. I had a chance to drive it, and I was thoroughly disappointed. I then drove a DSG version of his car (which has identical gear ratios as the manual - both are 6 speeds too), and the DSG version absolutely ripped. I won't get into why, but it was significantly better.

Which part of Drive train loss do you not understand. Herrschaft explained it pretty well in his one sentence but you typed a story book. I do not have time to pull up dyno's but the automatic transmission will rob a greater percentage of horsepower than the manual. You are looking at power to the crank and what you NEED to be looking at is POWER TO THE WHEELS. This accounts for loss in HP from transmission, driveshaft, differential, axles, wheels and so on and so forth.
On paper. In reality (where I like to hang out) the faster car in your scenario will be determined by the driver.
The 6MT G is faster than the 5AT enough that you don't need Lewis Hamilton to win...
