If Tesla’s Model S all-electric seven-seat sedan were in high school, it would be the kind of girl every heterosexual boy would lust after and every teenage girl would want to be.

At least, that’s certainly the line being taken by Tesla in its latest teasing track-test video, in which not one but three of its Model S Alpha-build cars streak around an undisclosed banked test track.

Sexy, fast and highly desirable, the three test cars zipping past with little more than tire noise and a high-pitched whine certainly give the brand a desirability it is very hard to capture in anything but real life.

And yet the video does.

There’s really nothing new in the 43-second video, but seeing three test cars in the same place tells us Tesla is working flat-out with to finalize a production intent vehicle in order to meet the Model S’ proposed 2012 launch date.

Combine it with the lack of camouflage and laid-back attitude to spy photographers at the track where the cars were being tested, and we have to agree with our own Nelson Ireson: Tesla needs us to keep talking about the Model S. After all, with production of its iconic Roadster already ended and unsold stock running out fast, Tesla won’t have another car to sell until the Model S launches.

There is one final thing we notice though.

Thanks to the wide-angle low-slung shots used in the video, and the all-black gloss paintwork, bright lights and high-pitched futuristic whir as it went past we think the Model S is now officially a cross between Dr Emmet Brown’s Time Machine and KITT, the autonomous crime-fighting automotive sidekick of David Hasselhoff in Knight Rider.

Sadly, we don’t think the 2012 Tesla Model S will feature either a flux capacitor or a super-smart --if somewhat annoying-- artificial intelligence.
