Fiat Chrysler, PSA tie-up: How will it work?

Fiat Chrysler Automobiles and PSA Group plan to merge in the biggest auto tie-up since Daimler's ill-fated purchase of Chrysler in 1998. The merger will help the two automakers to shoulder the costly investments in new technologies transforming the industry, creating the world's fourth-biggest automaker with a market value of about $47 billion.
