Ford revealed today that it has hit a critical milestone in the connected car world: the automaker has produced 10 million Sync-equipped vehicles since launching the technology just six years ago. Calling every Sync vehicle connected is a bit of stretch, since in its most basic form it’s essentially a voice command and control system. But Ford has been adding features to Sync over the years, allowing it to integrate with apps on those smartphones. Sync is also becoming standard across most of Ford’s vehicle lines. Since January of 2012, Sync has arrived in 6 million cars.
