Mariner provides you with the power of choice. To best meet your needs, Mariner lets you take your pick of three engines. Mariner I-4 features a Duratec 2.3L DOHC I-4 engine with 153 horsepower and 152 lb.-ft. of torque. It has an EPA-estimated mpg of 20 city/26 hwy (FWD), 19 city/24 hwy (4WD).

Want more power? Choose the Duratec 3.0L DOHC V-6 engine on the Mariner V-6 and Mariner Premier. This engine delivers 200 horsepower and 193 lb.-ft. of torque. That’s enough power to pull up to 3,500 lbs., when properly equipped. The V-6 engine has an EPA-estimated mpg of 18 city/24 hwy (FWD), 17 city/22 hwy (4WD).

The V-6-like acceleration of the Mariner Hybrid engine is yet another option. The 2.3L 16-valve I-4 gas engine with a permanent-magnet electric motor delivers 155 net horsepower (electric motor and gas engine combined) and 124 lb.-ft. of torque. This gas-electric combination has an EPA-estimated mpg of 34 city/30 hwy (FWD), 29 city/27 hwy (4WD)**.

Mariner is the first full-hybrid premium SUV in the world. As a full-hybrid vehicle, it can run on electric power at lower speeds (up to about 25 mph), while reducing exhaust emissions. The gas engine then seamlessly takes over, providing V-6-like acceleration.

When braking to a stop, the regenerative system captures kinetic energy from braking and uses it to recharge the 330-volt sealed nickel-metal-hydride (NiMH) battery pack. The battery pack, in turn, supplies electricity to start the electric motor, allows it to power the vehicle at low speeds and boosts acceleration.

Mariner Hybrid is produced under a carbon-offset program - a claim no other hybrid manufacturer can make. By funding U.S.-based renewable clean energy projects that reduce emissions elsewhere, Mercury offsets greenhouse gasses at its Kansas City plant by the same amount released during the manufacture of each 2008 Mariner Hybrid.

Get enhanced traction when you need it most. Whether the road is filled with gravel, covered with ice or soaked by rain, the Intelligent Four-Wheel-Drive System (4WD) helps provide more sure-footed traction. Because 4WD is fully automatic, it instantly delivers traction to the wheels needing it the most when wheelslip is detected. Optional on all Mariner models.
