The intention is for the production version is to have a 7.2kWh lithium pack which will have a maximum electric-only range of ~70 miles or about 40 miles in everyday driving. Then the generator starts up and you can keep driving, similar to the Chevy Volt.

The AX Eco Project : 100 mpg target !   The AX Eco Project : 100 mpg target !
In the 90's, the super light CitroŽn AX diesel held a Guinness record as the most efficient production car available, capable of 65 mpg (US) at 56 mph (90 km/h). HypermilerAX's modifications have already improved this to 80 mpg (US) at 56 mph. Now he's aiming for 90 mpg to beat the 1994 "AX Eco" concept car, and is also eyeing a 100 mpg tank (2000 km).

Manual vs. automatic transmission MPG showdown: Nissan Micra 1.6L   Manual vs. automatic transmission MPG showdown: Nissan Micra 1.6L
The Micra's official ratings are almost the same for the automatic and manual transmission. Yet the 5-speed can be much more efficient in the real world using just one simple ecodriving technique. Again we see the EPA handicaps manual transmission cars due to dictated, non-eco shift points during testing.

Front Air Dam ABA test results: 7.49% increase in MPG at 60 mph (2003 Honda Civic DX)   Front Air Dam ABA test results: 7.49% increase in MPG at 60 mph (2003 Honda Civic DX)
The addition of lawn edging air dam to this 2003 Civic DX shows very good results in testing: mileage jumps from 44.7 to 48 mpg in multiple 60 mph comparison runs. The downside: it scrapes a lot in normal driving. (Just like the very deep factory air dam on the Chevrolet Volt.)
