McLaren released a new teaser video for the P1 hyper car, but unlike the previous teasers, this one shows a working prototype in action. We even get to see bits of the interior. It probably means they are going to bring the production version, or at least a production-ready concept complete with powertrain and everything, to the Geneva Motor Show. We’ll keep you posted on any updates. For now go check out the teaser video after the jump.
