Edmunds' Inside Line on 2010 Prius

bengarland · 06-04-2008, 09:45 AM

Actually I read that the "83 mpg" quote for the current Prius (and "94 mpg" for the Gen III) is based on some weird Japanese fuel economy test that doesn't reflect real-world conditions at all. Anyone know about this? They are saying that the 2010 Prius will only get about 10% better fuel economy than the current model (e.g. 48 mpg vs 54 mpg in the real world).

I could maybe see thats true if we were only changing battery types... but if its plugin, that should drastically improve gas mileage for short commuter trips especially.

Even if they didn't go plugin.. I would think a " bigger higher capacity" battery and/or going lithium would also really help mileage.... there is only so much advantage you can get from kinetic storage and payback with a small battery. Going plugin, would solve that problem too as they would have to go bigger on the battery.

83mpg US is 35.5km/L or the official rating for the Japanese 10-15 cycle.

Also seems to touch that "magic 100 MPG" mark, assuming G is Imperial/UK/Old Canadian gallons. About 2.8 L /100KM.

So does Toyota engineer their cars specifically to meet the Japanese "benchmarks" ? Mention of something related to that in this thread: http://priuschat.com/forums/fuel-eco...tml#post635410

Perhaps if we understood the Japanese tests better we might find a co-relation with the "sweet spots".
