A new powertrain lineup, with a more powerful and fuel-efficient 2.5-liter four-cylinder engine and a new six-speed automatic transmission, leads the list of enhancements for the 2009 Mercury Mariner.

Mercury Mariner boasts better fuel economy, thanks to a combination of the new engine and fuel-saving six-speed transmission. Other fuel-efficiency measures, such as refined aerodynamics and new low-rolling-resistance tires, also enhance fuel economy while contributing to a quieter, more refined cabin environment.

Mariner for 2009 introduces Easy Fuel capless refueling, ambient lighting and standard cruise control.

The 2009 Mercury Mariner offers a new, 171-hp, 2.5-liter four-cylinder engine with intake variable cam timing for enhanced fuel economy and performance. The new engine is expected to gain 1 mpg in both city and highway fuel economy when equipped with the new six-speed transmission.

Responsive with its peak 171 lb.-ft. of torque at 4500 rpm, the engine also is refined, with dual-mode crankshaft damping, electronic throttle control and PowerPC engine electronic control.

The new I-4 engine’s full fuel efficiency potential is enhanced when it is equipped with the optional 6F-mid-range six-speed automatic transmission. A five-speed manual transmission is standard equipment.

Base model estimated mpg: 20/28

Estimated starting price: $22,310
