Besides the dihedral doors, there's not much to go off of. Dihedral doors aren't new, as McLaren uses the units on its entire range (as do other cars, mainly exotics), but the rear-hinged ones are unique. We've seen suicide doors and falcon doors on four-door vehicles, but no rear-hinged dihedral ones intended for production that we can recall. According to Fisker, the upcoming model uses the fancy doors for better ingress and egress.

Other than the nifty doors, the front fascia has what looks to be LED accent or running lights on the side, while the rear taillights are also LED units. As Fisker claimed earlier this year, the upcoming electric car will be a "spiritual successor" to the Karma and that shows in the profile of the car, although the teased car has shorter front and rear overhangs.
Fisker hasn't released a lot of information on the upcoming vehicle, besides that it would be "sporty and spacious." The outline of the vehicle definitely looks sporty, but there's no way to say if it's spacious from the one image. The new vehicle will be Fisker's first under his new company called Fisker Inc. The battery technology for the vehicle is currently being developed at UCLA, by the company's own battery division known as Fisker Nanotech. The vehicle is expected to be revealed late next year.
