drivetrain efficiency

A 180–hp sports car of frontal area 1:72 m2, with a drag coefficient of 0.31, requires 17 hp to cruise at 100 km=h. At what speed does aerodynamic drag first exceed rolling resistance? The rolling resistance is 1.2 percent of the car weight, and the car mass is 1250 kg. Find the drivetrain efficiency. What is the maximum acceleration at 100 km=h? What is the maximum speed? Which redesign will lead to a higher maximum speed: improving the drive train efficiency by 6 percent from its current value, reducing the drag coefficient to 0.29, or reducing the rolling resistance to 0.91 percent of the car weight?
