Are Graphene Micro-Supercapacitors An EV Gamechanger?

Energy density isn’t the only reason why battery-powered cars have never caught on. As was highlighted in Tesla’s somewhat less than successful media road trip, the amount of time it takes to fill batteries with electrons can be as significant a factor in the practicality of EVs as the amount of electrons those batteries can hold.

Paul I don't know how GM can fail to sell sedans. Other manufacturers seem to be able to, as others have noted. The Impala (which I've had as a rental) was a very nice sedan and the Malibu (which I had as a rental more recently) was a pleasant, competent vehicle also. Maybe they are still suffering from the bad rep they got in the malaise era into the 80s.
Kwik_Shift_Pro4X How a Versa that's a $18000 car became a $24000 car says a lot. Or even the jacked price of the current Frontiers. Not worth it.
MaintenanceCosts They should focus on major non-Interstate routes in the flat West. I recently did a central Texas trip with a Model S rental. It was just fine along the interstates but there were significant gaps on the big federal highways, which caused a bit of extra driving to reach charging stations. The one public (non-"customers only") charger in the greater Fredericksburg area was very busy, even at non-peak times.
Tassos Real Cars are RWD.So if you want a Lexus, try either the GS, or the flagship LS460 (before they mutilated it into the current failed model)The ES used to be a rebadged Camry, then became a rebadged Avalon at $10k more. Not a wise buy, unless you are a silly snob and would not be caught dead driving an econobox.
Ajla Sounds like the pinstripes, nitrogen, window tint, TruCoat, and "filing fee" is about to go up. It is pretty fun to see a $18K Versa with $3k in add ons.
