Back in September, we were lucky enough to catch a glimpse of the Concept One -- the first electric supercar from Croatia's Rimac Automobili. Boasting a full 1,088 horsepower and capable of going from 0-62MPH in just 2.8 seconds, the Concept One is still very much a concept, but today, we've got video proof that it actually works. Spotted by an eagle-eyed tipster, the 70-second clip is a bit shaky, and doesn't show the car doing much more than pulling out of the driveway, but at least it's something. No word yet on whether the Concept One is moving any closer to production, though we're certainly keeping our fingers crossed. Cruise past the break to see it in action for yourself.
