If I am wrong I will have no problem admitting it. But everything that I have seen for the 2006 has said there is a difference of 18hp with the auto and 6spd. If there is a source that says otherwise can someone post it?
Good job on the win!
wikipedia is inaccurate... i checked there a long time ago, and their information is incomplete.... I don't mind going over this with you because I was confused for a long time also... there is a lot of misleading information out there and its hard to put it all together... let's break down the cars by transmission
G35 coupe Automatics: from 2003-2004, they used the VQ35DE engine, this was rated at 280HP... even in infinitihelp, you can see that... in 2005-2006, they used the same VQ35DE in the automatics, they were still rated at 280HP, but they now had a higher rev limit.. the rev limit increased from 6200 to 6600, just like our Vq35DE engines have in the A/C's. Now, in 2007, the SAE (Society for Automotive Engineers International) updated their guidelines which in effect caused automotive companies to be MORE ACCURATE with the release of their HP ratings. Thus, in the 2007 model automatic G35 coupes, they are listed at 275HP, not the 280 hp previously listed. This can also be observed in Infiniti help.
So at first glance, one may think that they HP of the engine went down, but this is NOT accurate. So go to the same Infiniti help link you sent me, click 2006, and then go to SPECS, you'll see 280 and 298 for auto and manual coupes... go to 2007, click specs, and you'll see 275 and 293 for auto and manual coupes...
The same phenomenon can be observed in vehicles like the Lexus SC430, which from 2005 to 2006 apeared to drop from 300HP, to 288... but the horsepower didn't change, it was always REALLY 288, had the same standards been followed in 2006 as the new standards, then they would have listed the correct value of 288.
So in essence, companies were forced to STOP overrating their engines, and be more accurate... of course this information is not plastered everywhere on the internet, because no compay wants to admit that they were fudging their numbers in the past to make their cars appear to be more powerful.
For a description of this in the Edmunds review, follow this link
http://www.edmunds.com/infiniti/g35/review.html
in there, there is this paragraph
edmunds review wrote: "Both sedan and coupe shared the same 3.5-liter V6, but the sedan originally made less power (260 hp with four doors, 280 with two doors). They were made even at 280 hp for 2005, and both models when equipped with the six-speed manual option got a boost to 298 hp. These horsepower numbers dropped to 293 and 275, respectively, for the '07 coupe because of a change in SAE testing procedures -- actual output did not, in fact, change."
hopefully this clears things up a bit
information about the "Rev Up " engine is also not as clear. For on infinitihelp, they have even the 2003 and 2004 engines being 6600 RPM, while this review back at the time that the vehicle came out
http://www.edmunds.com/insidel...00427
clearly shows that the max RPM on that engine was 6200.
Again, if you look at one place, you will not get all the answers, this all confused me just as much as it is confusing you right now... but the accurate numbers are there, if you are willing to dig for it... here's another excercise for you... try finding accurate 0-60 and 1/4 mile numbers for the G35 coupe with automatic transmission!
