Per gallon, liter, whatever. The problem with E20 is that it's 20% ethanol, and ethanol isn't very energy rich (one liter of ethanol has only about 2/3 the energy of pure gasoline). Bio-diesel, though, has the same energy content as normal diesel.
It also has to be remembered that Audi have run B10 since 2008, while E20 is new to both Porsche and Toyota for this season.
