How could anybody claim HRT have 70bhp over a competitor's engine? It's not the horsepower that gives the car grunt, it's torque and how well that torque is transferred to the ground. The HRT/HSV cars get out of corners very well. As a point of comparison, Lowndes' 888 car seems to have the best mid-corner speed in the field but the trade off is that its slower out of the corners and the terminal speed is therefore compromised.
Anyway, the best indicator will be the drag up mountain straight. All uphill and at the rev limiter in 5th.
