Peugeot has showcased a hybrid that stores energy from braking as compressed air instead of in a battery - the HYbrid Air. Per that article it gets 118 mpg US but I assume that is on the EU mpg test cycle. I am assuming though that they do mean US gallons and not Imperial gallons.
Anyone know how that translates into the US mpg cycle? The best I can figue is that would be edging near 100 mpg US cycle but I’d love somebody with a better grasp to tell me if I am close.
can’t really compare w/o actually testing the car to the EPA drive cycles. As a point in comparison, the UK market Prius is listed as achieving 72 mpg vs. 51 for the US market car. The differences in US vs Imperial gallons isn’t enough to account for that much of a difference. as far as I can remember the EU drive cycle is rather “generous” compared to the 2008+ EPA test.
If you convert the 2L/100km figure also given in the link to miles per US gallons, you indeed get 118 mpg. That isn’t what this car gets yet though. Per the article:
If you follow this link in that article, it appears that the compressed air hybrid is rated to acheive 97 mpg.
As for what that translates into in US cycle terms, as jz78817 said, you would probably need to actually run it.
Belated update - it won’t get any mpg.
