Super up-close look of the proto's underside, wheel wells, exterior, and interior..
Put closed-caption on and translate to English you can get an idea of what they're talking about.
Some cool stuff we haven't seen anywhere that are showed in this video:
3:00 - close up look at the exhaust and underneath the rear of the car
5:05 - close up look inside the front grille
12:48 - see the low beams and high beams turn on
13:40 - turn signals turned on (would be much cooler if the rear turn signal strip was sequential)
