Hi Bob Wilson,
Do you have a source for this formula? In context of EPA dyno testing, it looks like the estimated road power at 50 mph. The proper conversion coefficient, considering units of lb and mph, should be 375 and there should be another mph term:
drag HP = v * (A + B*v + C*(v*v)) / 375
using 26.050,-0.01200,0.018200 as A, B, C for the Volt I get
9 at 50 mph
55 at 100 mph
