Karma has let Wired take their first plug-in offering out for an early test spin (video above), letting a few additional details out of the bag:

like the fact that the solar roof (rated at 200W) will now power the HV battery (not just the 12V) to give the car additional range when out in the sun,

at least 10 cars have already been built,

and that the infotainment system no longer…erm, sucks
