That's how it looks under direct light. From the side or in less light, it is more charcoal gray...honestly, though, you need to see it in person to evaluate as monitors often skew colors.

euro plate center grille holder that's for sure

Its not my shot. I copied it from another site. I believe it was from an Audi premier at some autoshow in Stockholm.

It test drove the 4.2 in Houston this weekend. The gray is just a slight darker hue than the Dolphin.
