That's a tester.....all the preproduction tester X6's have/had two stainless steel wire mesh exhaust vents on the hood.Maybe the Hybrid X6?.....I need to ask some of my contacts why BMW felt the need to vent hot underhood turbo temps in testers,but not production cars???? I've always thought those vents added a nice little sporty look to the hood!! Disappointed they did not make it into production. Nice pic!!! Thanks.PalBay
