most all wheel drive cars are slower off the line than their two wheel drive counterparts.
That's plain wrong. All else being equal, AWD is always faster off the line because you are usually traction limited at launch, and AWD allows you to hook up all your tires when you dump the clutch. They are slower afterwards because of the extra weight and drivetrain losses, but no doubt they can take off like a bat outta hell from a full stop.
