Another day, another truckbed-full of news in Detroit. Fiat Chrysler made arguably the biggest splash with its announcement that it plans to invest $4.5 billion in five Detroit-area plants and create nearly 6,500 jobs. Central to that is plans to convert the Mack Avenue Engine Complex on Detroit’s east side to an assembly plant to build the next-generation Jeep Grand Cherokee and a yet-to-be-named three-row Jeep SUV. If all goes according to plan, construction could begin by mid-year.
