The front-wheel or all-wheel drive Flex is powered by a 262-hp 3.5-liter V6 engine. Available on all-wheel drive models only is a 355-hp 3.5-liter twin-turbo V6 engine featuring EcoBoost. Both engines are mated to a six-speed automatic transmission, with the EcoBoost models providing steering wheel paddle shifters. Seven-passenger seating is standard on all trim levels. Available features include the SYNC communication and entertainment system, a Multi-Panel Vista Roof, interior refrigerator, and capless fueling. Standard safety features include four-wheel disc brakes with anti-lock, electronic stability and roll control, six airbags, and a tire pressure monitoring system. For 2012, the second row bench seat in the Limited and Titanium now includes a flip out armrest with two cupholders. The EcoBoost engine is no longer available on the SEL AWD trim.
