The new logo cranks up the texture effect on the wreath, adds texture inside the crest, and plays up the embossing and light effects of the crest edge. It's new, but it's got a shiny bit of retro about it that we don't mind.
Cadillac doesn't appear to have said anything about it, and while it appears on the 60-day Guarantee site we can't tell if it's made it onto Caddy's official plot of the interwebs. The real test, though, will be how it looks when it makes it onto the cars. Thanks for the tip, Scott!
