I know those numbers seemed low, but they match AirRaid's.

Anyway, it might not be that well broken in yet. It's at 4500 miles, but many many highway miles in there. Plus it wouldn't let us turn off the stupid traction control on the dyno... probably because it threw a ABS light because the front wheels weren't spinning. So that may have had a lot to do with it.

That partiular shop wasn't the best at doing this anyway. I'm probably going to have to go find a different one. They are really close, but everything I go there they don't know things that they should about the software.

Those numbers you quoted is what I really expected.

 

Okay.... verfied this at another style dyno. Pulled about the same. 248, but the torque as higher... 285 if I recall correctly.

Anyway, we just have a drive train loss of about 25%. I found out that's not that uncommon.

Anyway, on their simulator I ran a 14.3 quarter mile based on a 4125 lbs. No power braking or loading... just stomp on the accelerator and go.

 

That's pretty quick for a car that heavy.

 

I am thinking that the all wheel drive models will actually put more of the power to the ground. Anyone care to second that theory or shoot it down?

 

I would think that the cars with all wheel drive would be slower (less horsepower) due to more frictional losses of power.

You can't have your cake and eat it too.

If you're having a big problem spinning the tires on acceleration, yes. Otherwise, the added weight is just going to hurt. I have to imagine it's going to add 200lb. more. [:@]
Where it will come in handy is if you're doing a brake stand to bring the revs up before launch. I'd be concerned about complete and spontaneous disassembly of the driveline pieces when doing that, though.

 

All wheel drive vehicles tend to have better punch off the line. However, they also have more loss through the drive train. My guess the AWD will have loss in the 28% range and we are already in the 25% range.

AWD is also suppose to weigh about 300 lbs more.

With this car, I don't think it will be of any real advantage becuase I'm willing to bet it will be much more fragile than just a RWD version.
