-- other questions remain. For instance, it?s reported that the battery in question is a 98 kilowatt-hour pack. So even if the company?s results hold up, are they that impressive when you take in account that Tesla?s Roadster already gets a 245 mile range from a lower capacity 56 kilowatt-hour battery pack? --

You sound upset that they packed more energy into a lighter battery than Tesla. If you put the 98 kwh pack into the Tesla you will probably see comparable range performance.

Any improvement or drop in range would have to do with the car design.
