Tesla Motor’s blog has a customer post on how he helped sound engineers at Microsoft Games Studios sample squealing roadster.

…engineers from Microsoft Game Studios (some working on Forza, some on Project Gotham Racing) asked if I was willing to take my Roadster to a track so they could record a variety of sounds. Some time ago they had the opportunity to record Tesla motor noises when a prototype was being run on a dyno at Tesla. But the teams were excited about the prospect of recording other sounds, particularly tire skid and squeal noises, without the interference of loud engine and exhaust noise. Of course I said “yes.”

The teams arranged to use a local motorsports park that was formerly a small airport. We met early (7:30 AM!) so they could mic-up the car. Two hours later, they had three large boom mics “suction-cupped” to the side and rear of the car, plus a mic in the trunk, and two up front over the swaybars and near the front tires, plus one in the cabin interior, the latter mostly to record verbal “clapboards” to identify each segment. A sound engineer with the recording deck rode shotgun and I did the driving.

Who knew exotic $100k electric sports cars elicited such exotic requests to borrow the keys.
