After almost a decade, the three-row Traverse has been redesigned for 2018. It's based on the same platform as the new GMC Acadia but is longer and even roomier. The current Traverse has been showing its age, with outdated controls and thirst for fuel, with 16 mpg overall. On the other hand, the new Acadia we tested impressed us with its quiet interior; steady, composed ride; and responsive handling. The 3.6-liter V6 supplies ample power. The infotainment system is comprehensive and intuitive. Like the Acadia, the new Traverse will have a rear-seat minder to ensure that no infants are left behind. Maximum seating capacity is eight, but most versions will be seven-passenger configurations with second-row captain chairs.
