For better ride, handling and brake cooling the Acadia offers optional 22-inch wheels. The Passport’s largest wheels are only 18-inches.

The Acadia’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Passport does not have an oil pressure gauge.

The Acadia offers an optional heads-up display that projects speed, tachometer, navigation instruction, infotainment and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Passport doesn’t offer a heads-up display.

The power windows standard on both the Acadia and the Passport have locks to prevent small children from operating them. When the lock on the Acadia is engaged the driver can still operate all of the windows, for instance to close one opened by a child.
