Active Fuel Management
Active Fuel Management™ shifts from eight cylinders to four and back again. In situations where extra power is not needed, such as cruising down the highway on level roads, Active Fuel Management™ deactivates half of the cylinders with seamless precision. When load demands increase, such as when the vehicle accelerates or travels uphill, cylinders are reactivated to provide full power. Best of all, you don't have to do a thing and it all happens seamlessly. Watch how it works.
