Tesla's not the only luxury electric vehicle maker in town. Porsche is showing off an EV concept at this week's Frankfurt Auto Show that will take you from zero to 60 mph in 3.5 seconds.

The Mission E, currently just a prototype, will include support for eye-tracking, gesture control, and even holograms. Plus, a rear-view-mirror-mounted camera recognizes if the driver is in a good mood, and showcases it as an emoticon that can be shared via social media.

It runs an 800-volt drive system, or double what is found on today's EVs, and has a 310-mile driving range. Porsche tipped a 15-minute charge time to reach 80 percent with the 800-volt port on the front left wing, though drivers can also use 400-volt charging stations if necessary. The Mission E could also be charged via a coil embedded in the floor of the garage.

"Every square inch, every angle, every radius of the Mission E reflects one thing above all else: emotional sportiness in the best tradition of Porsche design," the Volkswagen-owned company said in a news release.
