The full-size, three-row crossover segment is relatively new to the automotive landscape. You need to look back only four or five years to see how quickly the segment has changed from just a handful of models to more than 15 models today.
For folks who find minivans anathema, these large crossovers are the best alternatives. Some — like the Chevrolet Traverse — are roomy enough that there's little tradeoff in terms of passenger room. The unibody architecture of large crossovers makes them generally more maneuverable and fuel efficient compared with three-row, full-size SUVs, like the Chevrolet Suburban and Ford Expedition.
The full-size crossover market will expand soon, with the three vehicles on the horizon: the 2013 Nissan Pathfinder (which switches to a crossover platform), the 2013 Infiniti JX35 and the upcoming Jeep Grand Wagoneer.
