Tesla Model S Alpha build cars testing on trackEnlarge Photo
Just yesterday we brought you spy shots from what appeared to be a hot-weather testing session, and which has the same setting as this official video released today of three Model S Alpha build cars testing on track.
The track is partially banked, enabling easier high-speed testing, but also has traffic and road markings--with speeds laid out in metric--making us think Tesla has borrowed another automaker's testing grounds for the Alpha's shake-down.
Other than that, there's not a whole lot going on in the video--except the increasingly less-eerie sound of electric cars whipping along at high speeds, with just the thrum of the tires and the occasional whine from the electric motors and controllers.
Between all of the badge-flashing and the complete lack of camouflage, not to mention the official release of the video, it's clear that Tesla's Model S development will be a marketing event rather than the typical clandestine affair of conventional carmakers.
