Nothing new there.

Except more information about vehicles that in a specific context are more efficient than the Prius... perhaps you should have read it closer.

Prius with 5 seats even at ~50 MPG = ~250 passenger MPG

from your own citation:
Quote:
A diesel bus commuter service in Santa Barbara, California, USA, found average diesel bus efficiency of 6.0 mpg-US (39 L/100 km; 7.2 mpg-imp) (using MCI 102DL3 buses). With all 55 seats filled this equates to 330 passenger-mpg
= more efficient than Prius.

Your own citation lists walking as:
Quote:
roughly 360 MPG
= also more efficient than Prius.

And just to drop the hammer ...
Also from your own citation:
Quote:
Association of American Railroads USA 2007 436 mi/gal (166 km/l)/short ton (907.2 kg)
= more efficient than Prius.... a short ton of people is a lot of people... at even 100kg per person ... that is 9 people * 436 = 3,924 passenger miles per gallon ... for a 5 seat Prius to beat that ... means the Prius with 5 passengers in it needs to achieve better than ~784 MPG ... sorry dude ... I know you are pro Prius ... but that is just ...
not going to happen.
