But yeah, once they hook up, AWD cars are just carrying extra weight and additional parasitic powertrain losses.
It was pretty cool and dusty so that was probably a big part of it. I think maybe next time it might be worth it to get a street sweeper out there to clean up the first 1/8 or 1/4.
We had it swept a few days before the event, just a dusty area, hard to keep it clean.
