I wished Ford was part of the group.
They are. Kind of. With their new Sync 3 infotainment system. It's slowly rolling out, but available on:
(All 2016's)
-Edge
-Fiesta
-Focus
-Mustang
-C-MAX
-Escape
-Expedition
-F-150
-Transit
Sync 3 uses app support but "Ford is planning to offer Apple's and Android's API in the future, Williams said, but there's no specific release date."
Hyundai also has it on their 2015/16 Sonata and 2016 Tuscon (coming soon with software update). Not sure why they aren't included on this list
