2011 Nissan Patrol

[Galaxy]

397km/h? No way.

397km/h? No way.

Yeah it does seem unlikely, though apparently the most powerful Patrols are putting down 2000hp or something.

I think it's just the guesstimation based on how far around the speedo went or something (probably not accurate and highly optimistic)

Like this guy here.

Acceleration wise though, they should be a good match for a veyron.

Here's a patrol playing with some Hayabusas.

Here is a drag prepped one trapping about 160mph in the 1/4 mile.

8.8 seconds.



I wonder if you could drop this engine into say... a 240SX.

^WHy does all this crazy shit only happen in Dubai?

[Submariner]

While the power is there, I'm not sure the aerodynamics would allow for such ridiculous speed...I could be wrong though.

[nickdrinkwater]

The Escudo could top 400km/h on GT3

What? You just need more power to overcome aerodynamic drag

The Veyron just barely manages to break 400km/h. Of course this apparenty has 400 or so more horses under the hood, however the wind resistance of this thing is going to be much worse. Would not surprise me if it is more then three times as high.

Surprisingly, the Veryon isn't as aerodynamic as you might think.  Google tells me it has a "normal" Cd of .41, and when it's in super-awesome-shit-your-pants mode, it drops to .36.  Respectable, but there're plenty of production cars with lower Cd than that.  Such as...a Mazda6, a Genesis, a Mercedes, a G37...

Many super/hyper cars have high Cd's to promote downforce.  Even still, an SUV of the Patrols size is going to have far, far greater levels.

[giant_mtb]

Of course, but drag is drag.  Tahoes and Durangos have Cd's of .39.  Regardless of how the air force is being applied (as down- or up-force), that's how much drag it experiences.  I'd suspect a Patrol's Cd to be of a similar quantity and thus find it believable that one could achieve such speeds with that much power.  400 more HP than a Veyron in a vehicle with a slightly worse Cd...I can see it.

[GoCougs]

Not to nit pick, but Cd is meaningless without frontal area.

The highest performance 4-wheeled vehicles of the land (F1 cars) have atrocious Cd for reasons of down force - easily double that of your average passenger car car - however, it's relative minor in context since frontal area is so small.

Don't forget about Cd * frontal area.

McLaren has solved the Cd problem this season with this:




And the engine cover:





Normally the air gets blown into the cockpit, but on a straight the drivers put his knee over the hole which changes the air pressure and causes the air to get channeled through the car and the engine cover to hit the rear wing in a way that causes it to stall, lowing the air resistance. The McLaren has by far the highest top speed in this years grid. The trick gives them a 10km/h lead.
Of course the other teams complained since active aero on the rear wing is illegal, however the FIA ruled that since it is dependent apon the driver and not the car it is consistant with regulations. The FIA's technical Director Charlie Whiting called it "Simple but brilliant."

What do you mean it's meaningless without frontal area?  Frontal area is in the equation for Cd...?  You can't calculate a drag coefficient without an area...

Citing Cd by itself is meaningless in the context it was being discussed (drag).

[giant_mtb]

So....you're saying that the coefficient of drag is meaningless when talking about, uh, drag?

[giant_mtb]

"In fluid dynamics, the drag coefficient (commonly denoted as Cd, Cx or Cw) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment such as air or water."

[S204STi]

Look at it this way... a city bus might have the same Cd, but that doesn't mean it has the same drag.  At least that's what I'm gathering here.

EXACTLY.

Yeah, that makes sense since the power required to overcome drag force is given by:



...but he's saying that the coefficient of drag is meaningless when talking about drag.  Which makes no sense.

[S204STi]

No, he said that in this context it is meaningless.

[giant_mtb]

K.  I understand what y'all are sayin'.  And thanks for the enlightenment.

Looks like they stuck an Infiniti grille on it and hey presto, the QX 56:







Interior looks nice I guess.

[CALL_911]

Interior's nice, exterior is, um, unique.

I just read that the initially designed the QX and reversed it to the Nissan after. Interesting move

And it kinda reminds me of the Land Cruiser/LX

Actually, that's a very good point, not a nit at all.  Cd is a nice figure to throw around and compare academically, but without frontal area, it's hard to get meaningful real world data out of it.
