Anyways, here is the issue. I have arbitrarily picked 20 degrees since most roads don't slope higher than that. Since this is the torque to hold the car still, the angular acceleration is zero along with drag and the like.

Now, summing the torques will give the general equation (neglecting drag and friction):

Taxle = m*g*r*sin(hillangle) + m*r^2*(alpha)

In this case:

Taxle = 1500*9.8*0.2*sin(20) + 0

Or: Taxle = 1021.63 Nm (753.55 lbft)

Am I to believe that this is really correct?? Given that an average car has less than 200 Nm peak torque (at the wheels) this seems very off. Now what did I miss? This is driving me crazy!
