A mysterious McLaren prototype has been spied undergoing testing near the Arctic Circle.

A mysterious McLaren prototype has been spied undergoing testing near the Arctic Circle.

While the car wears an MP4 body, we can see "prototype vehicle" stickers and an "MV103" badge at the top of the windscreen. The latter identifier raises a lot of questions but out spies believe the MV part could stand for "mule vehicle." This seems plausible but it is interesting to note the upcoming Sports Series coupe carries the GXP102 moniker so this could be a mule for an all-new model or possibly another Sport Series variant

Regardless of what it is, the prototype was equipped with a new interior that had a revised dashboard and a unique speedometer. The cabin was also filled with testing equipment but there's no word on what was being evaluated.
