The 2008 Mercury Mariner is available with front-wheel drive or fulltime all-wheel drive, and either a four-cylinder, V6 or hybrid gasoline-electric powertrain. All models come with an automatic transmission.
Mariner ($20,920) and Mariner 4WD ($21,320) come with a 153-horsepower 2.3-liter inline four that generates 152 lb-ft of torque, matched to a four-speed automatic. A 200-hp, dual-overhead cam 3.0-liter V6 ($1,000) is optional. These base models come well equipped, with air conditioning, power windows, mirrors and locks, an AM/FM stereo with CD and auxiliary jack, rear window defroster, cruise control, privacy glass and 16-inch alloy wheels.
The V6 comes standard in the Mariner Premium ($23,820) and Premium 4WD ($25,570). This is the upscale trim level, with leather seating, a six-CD changer, automatic headlights and other features included.
Mariner Hybrid ($27,020) and Hybrid 4WD ($28,870) are equipped similarly to the Premium models, with the hybrid powertrain replacing the V6.
Options include the Cargo Convenience Group ($195), which adds a retractable cargo area cover and a compartmentalized rear storage bin. The Audiophile Package ($695) includes a high-power stereo with seven speakers, subwoofer and the in-dash CD changer. The Leather Trim package adds leather seating and adjustable lumbar support to the base model ($995) or Hybrid ($695).
The Audiophile and Navigation Package ($2,295, base, $1,995 Premium and Hybrid) includes the stereo upgrade and a touch-screen navigation system. In the Hybrid, it also adds a meter that graphically and immediately demonstrates the benefits of hybrid drive, and helps the driver maximize fuel economy. These are only the start of the packages, and there are also a host of stand-alone options for all trim levels, including CD changer ($295), a power moonroof ($795), floor mats ($75), 17-inch wheels ($650), and a Class II towing package ($395).
Safety features have been upgraded substantially for 2008, making equipment that was previously optional standard across the board, and raising the benchmark for small sport-utilities. Passive safety features include front- and side-impact airbags for front occupants, and curtain-type head protection airbags for all outboard seats. The side curtains can remain inflated for several seconds in the event of a rollover, and are designed to slide between the side glass and occupants if the people are oddly seated or resting heads against a window.
Active safety systems include four-channel antilock brakes (ABS), electronic stability control and a Roll Stability Control system. RSC adds a second gyroscopic roll-rate sensor to the typical stability control package, measuring the Mariner's roll angle and roll rate and applying countermeasures (such as braking one of the wheels or reducing power) to increase rollover resistance.
