There are body shell X1 prototypes, testing the whole vehicle, and there are still some special testings going on - eg. under this 3er mule etc.
I guess they've experiences some cooling problems in the original body prototypes & decided to run additional cooling tests on cheaper yet sufficient 3er mules.
As I said: check the X1 spy pics & compare the nose with this one on the 3er: they are identical!
Yes they are identical, I see those massive kidneys in both. I figured costs were the reason, but sometimes the photos are just old....
Still confused about the cooling issues unless this is a new engine. Because there should be a ton of air flow through those grills.
Rumors still floating about the N53 in the 3... so maybe it is or maybe it is a new motor all together?
