News has been charging out of California on the luxury electric-car front: Tesla Motors, the maker of the $100,000 all-electric sports car, has released the first pictures of the production version of its upcoming Model S, all-electric sedan.

The production car has more and larger air intakes in the front fascia for brake and electronics cooling. The "S" is supposed to have a 300-mile range with its most expensive battery offering, which would cost about $88,000. The Model S will be offered with smaller, less-expensive battery packs good for a 200-mile and 100-mile range, saving $10,000 and $20,000, respectively.

Meanwhile, Tesla announced it has stopped production of its original Roadster sports car, because Lotus, an English supplier, has stopped producing the "glider" chassis for Tesla.

And luxury plug-in hybrid maker Fisker, which showed its first running Karma prototype at the Monaco Grand Prix last month, announced in an earnings call that its first customer cars will be delayed slightly until July.
