Nobuhiro 'Monster' Tajima driving the Tesla Model S

Pure driving joy, with a big open-mouthed smile. That's what we see on the face of Nobuhiro 'Monster' Tajima as he puts a 2012 Tesla Model S through its paces on a test drive down some curvy California roads.

Best known for winning the Pikes Peak International Hill Climb six times in a row – including in 2011 when he became the first to accomplish the feat in under ten minutes. Tajima-san attempted to top that this year in his custom-built electric Monster Sport E-Runner Pikes Peak Special, but a motor failure less than a mile from the start ended his day. That short circuit, however, hasn't seemed to dampened his enthusiasm for battery-powered cars.

Indeed, the jovial racing giant appears to have quite enjoyed his time behind the Tesla wheel, as the video below shows him piloting the all-electric fastback like one might expect a driver of his stature would. Using the whole road and with little regard for the possibility of a speeding ticket, Tajima has his passengers both bracing and grinning nervously while he guides the Model S roller-coaster-like through the twists and turns.

His assessment of the new electric American hatchback? Well, scroll down for video of a little Monster-on-Tesla action and see for yourself.
