Over the years, those against Prius have used the EPA estimates of MPG as if they were actual expectations, rather than the ideal-condition comparison measure they were intended to be. That's just plain wrong, definitely not a sincere effort in any respect. But if they want to play the game that way... what the heck. Vue-Hybrid combined MPG estimate: 29 Vue combined MPG estimate: 24 Vue-Hybrid offers an estimated improvement of: 20.8% Prius combined MPG estimate: 55 Corolla combined MPG estimate: 33 Camry combined MPG estimate: 27 Camry-Hybrid combined MPG estimate: 39 Prius offers an estimated improvement over Corolla of: 66.7% Prius offers an estimated improvement over Camry of: 103.7% Camry-Hybrid offers an estimated improvement over Camry of: 44.4% The estimates clearly show at least twice the efficiency gain from the "full" hybrid technology over that version of "assist" hybrid. In other words, if Saturn/GM supporters are going to continue to push numbers from the EPA rather than what real-world data actually reveals, shouldn't we? Of course, we know quite well that the "full" hybrids thrive in real-world conditions, since that often includes lots of suburb and stop & slow driving. It's where we have a distinct advantage that the competition tries to avoid discussions about. So odds are we'll have to put up with the MPG estimates for a very long time still. * Note that all the non-hybrid combined estimate values listed above were from the smallest size engine available for that vehicle with an automatic transmission.
