2018 Porsche Cayenne rides high on air suspension, lighter unibody

Porsche's pioneering Cayenne crossover SUV enters its third generation in 2018 following six-year runs of both the first- and second-generation models. In its latest iteration, new technology permits the Cayenne to get ever closer to reconciling the conflicting priorities of the brand's sports-car heritage and its SUV off-road expectations.

The 2018 Cayenne is helped in its progress toward this by a lighter-yet-stronger unibody structure made with both aluminum and various grades of steel; it is Porsche's interpretation of the Volkswagen Group's MLB Evo platform, which debuted in 100 mm-longer form as the Audi Q7.
