DETROIT (AP) — The North American International Auto Show is opening to the public following a week of previews for the press, industry officials and others.

The latest cars and trucks are displayed at Cobo Center in Detroit along with concept cars that offer a glimpse at what the future of driving might look like.

Fiat Chrysler’s plug-in hybrid version of the Pacifica is a first for the minivan segment. Chevrolet showed the all-electric Bolt. And Ford showed updated versions of its Fusion hybrid and plug-in hybrid cars.
