https://www.autoblog.com/2021/01/07/2021-jeep-grand-cherokee-l-three-row-reveal/#slide-2287772This is a big year for Jeep SUVs, and we mean that quite literally. Not only is it launching a full-size SUV in the form of the Wagoneer and Grand Wagoneer, the Grand Cherokee midsize SUV is being completely redesigned and expanded, both in model offerings and physical size. That comes courtesy of the 2021 Jeep Grand Cherokee L, a lengthened version of the upcoming SUV that comes with a third row of seats, a first for the model.
This new Grand Cherokee L, and the two-row version that will follow later this year, are built on a completely new platform not used by any current product, nor the upcoming Wagoneer's full-size, truck-based platform. As with every Grand Cherokee before it, it has a unibody chassis. About 60% of it is composed of high-strength steel, and aluminum is used for the hood, hatch, shock towers and front subframe, all of which is to help keep weight down.
