I came across the following video on YouTube:

YouTube - 09 Infiniti G37x sedan 0 to 60mph

It seems this X sedan gets to 60 in about 5.5 seconds, which is a little quicker than what I've been able to achieve in my own X. If you watch carefully, you can see that the rpm's creep up to about 2,000 before an audible click and the mph starts to increase. Is this driver holding down the break at the same time he is pressing down on the accelerator get a better "jump" when he floors it?

I suspect this is a rather pedestrian question, and reveals my utter lack of knowledge about racing or performance cars, so I am anticipating a bit of flaming. I just wondered whether I was seeing what I appear to be seeing and whether it's bad for the car to do this kind of thing. If he is giving it some gas while holding down the break, does it actually help off the line?

Thanks for enlightening me.

That's called launch. It does help off the line.
I believe other people will chime in and expalin better.

 

THats brake torquing. Gas + brake to 2k rpms then release brake and floor it.

On a RWD car it will not do anythign for you but on an AWD it kicks you into the seat for a split second so it definately feels a little quicker at launch. Any measurable difference? Doubtful.

Here is another one: YouTube - G37 2009 Infiniti G37XS Sedan 0 - 60

 

lol sorry to threadjack but who's brilliant idea was it to do this race? it's got a freaking V10 people!

some people think our cars are fast but it is all relative to what you compare it to. anyone who tries to race an m5, shame on them

 

Driver of G37 has no business trying to pit against M5.. unless it was modded.
Looks like need more work too.

 

That looks like a g35(wheels) but whatever, some people race anyone just for fun... lol

Also at the track they sometimes line you up randomly, so maybe the guy was like "Oh, great...."

How bout this guy? See 53 seconds in --> http://www.youtube.com/watch?v=RU2IykYEnc8

 

It isn't race... they run for time record. Running with other car doesn't mean he's racing with someone..

 

Mmmmm hmmmm...

 

I want the Veyron and i d never race an M5. It s pointless..

 

I noticed in both of those 0-60 videos, the autos were in DS. Does this really make a difference in performance of a 0-60 run? I would have thought that even in "D" the car will go to redline.

 

Wouldn't the G37X be faster 0-60 than a G37 RWD unless it's that much heavier... motortrend caps the G37 Sedan S in 5 flat. And edmunds/insideline i believe does it in 5.3?? [correct me if i'm wrong about edmunds/insideline]

 

Edmund.com says M5 0-60 4.8sec, and 1/4 mile 12.8sec, G rwd 0-60 5sec, and 1/4 mile 13.4sec, but how come the video seems G is much slower than M5? it doesn't feel like different within one second......

 

First off, most G37s are running high 13's, not 13.4.

Second, 1 second in the quarter mile is huge. At 100 miles per hour, a car travels 145 feet in that one second. Basically, if both cars were traveling at 100 (the M5 will be going faster btw), the M5 would be ahead by 145 feet at the end of the 1/4 mile race.

 

the m5 is like 3 times the msrp tag of the g37 sedan is it?
