I don't think it was an error with the Prius.
The Prius was thrashed around the circuit where as the BMW was driven gently.

Driving style makes a lot of difference. My diesel car can return 17mpg(uk) or my best 84mpg(uk) depending on how I drive the same route.

Hig revving the CVT no battery power (or just a drain of battery) vs a midly running V8.

Note as well that the BMW drafted the Prius all the way around the track!

That's not even the lowest MPG a Prius can get.
The Correct Answer
0 MPG - about as low as you can go! But in an emergency, having power can be very important.

Of course, what really bothers me are most bus drivers. They leave their vehicles idling at every stop for no good reason. Especially bad are those at my university since I have to pay for that wasteful idling.

I love the way they are encouraging people to drive smarter in the car they have now Would have been nice if they did another go round at 55mph.

Driving a Prius at 100 mph is like throwing it in a lake and saying it doesn't make a very good boat.

Wouldn't this help them both, though? It's not like drafting was slowing the Prius down, right?

I actually think it works the other way around, that drafting off the back of a vehicle helps that vehicle moreso than it does the person drafting, because it (should) reduce the size of the wake area substantially (since the drafter's nose cone (thus, stagnation point) will be inside the wake during a proper draft technique).

Isn't it the opposite, that that the vehicle doing the drafting gets the better deal, although both do benefit? Take the slingshot from Nascar for instance. If drafting helped the lead vehicle more, the rear wouldn't be able to pass, but AFAIK the slingshot move works well because the car in the rear has a definite advantage that it uses to pass up the lead.
