Cool Videos: '08 Vette Twice As Fast To 100mph As '08 Yukon

[QUIKAG]

Yukon 0 to 100mph in 15.4 seconds:

 

 

Vette 0 to 100mph in 7.7 seconds:

 

 

Twilight zone or not? Both are 6.2L motors, so I guess the Vette can build speed a touch better.

Yeah, it's all about the power to weight ratio. And throw in a sh$tload of wind resistance at higher speeds. I can literally feel the wind resistance build in the 1/4 mile. 0-60 times are excellent but 70-100mph is a different story.

I couldnt view the video...but isnt the new vette with the 6.2 supercharged??

[SLESierra]

wonder what a 5.3L flex fuel vette could do in the woods?

Come on, throw me a bone. Obviously, I'm well aware of how weight, aerodynamics, gearing, and horsepower affect acceleration. Well, I guess it wasn't obvious. Anyway, the twilight zone comment was the fact that my recorded time for the Yukon was exactly twice as long as the Vette. I thought that was kind of coincidental.

 

Z71chev, the new '09 ZR1 Corvette has a supercharged 6.2L motor making 638hp. It's a complete monster. I have the base '08 Corvette with a 6.2L motor rated at 430hp.

With a Few Mods (Bolt on's) you can get 430 up closer to 480+. Any Pic's of your 08???

Haha, I'm not pickin' on ya, just being a smart-ass It is interesting to see what the same engine will do in different vehicles. It would be interesting to know exactly how much of the time difference has to do with drag, and how much with weight.

Here's a really bad picture the day I got it:

 

I do have an intake, long-tube headers, Corsa exhaust, and tune on the Vette, so it is definitely making closer to 480 crank horsepower.

 

I knew it wasn't a close contest between the Yukon and Vette, I just thought it was interesting. I LOVE my Yukon and think it is damn quick for what it is. The Vette is fast, but it was designed to be fast. The Yukon is quick, but it also seats 7, tows 8,000 lbs, and gets pretty good gas mileage (I'm averaging close to 17mpg with my 75% highway commute)

Drag has to play a big role. Notice the speedo and how it just really starts to slow down around 70mph. As Bish said, you can almost feel the huge wind resistance as you are accelerating at higher speeds. The weight obviously doesn't help, but I bet the aero plays a bigger role at higher speeds than the weight.

Hey, if anyone wants that K&N Series 63 intake that is on my Denali (it fits a lot of GM truck/SUV), I have a hookup. Model number is 63-3058. The family of a good buddy of mine owns a large aftermarket truck parts distributor here in Texas. He can sell the 63-3058 (and probably a bunch of other models) for $265 shipped to your door. That's quite a bit cheaper than I've been able to find anywhere else on the net.

 

If interested, shoot me a PM. I don't get a dime off these sales, just trying to hook my GM truck brotherhood up.

That theory of drag v weight "feels right", but data would be nice. Throw a couple thousand pounds of weight in the trunk of your vette and give it a run; from there we can solve for the impact of drag.
