The 2010 Ford Explorer lineup is largely unchanged for what is likely its final model year in its current design. This midsize SUV uses traditional, truck-type construction. It offers rear-wheel drive, all-wheel drive, or four-wheel drive that can be left engaged on dry pavement and has a low-range gear for off-roading. Trim levels include XLT, Eddie Bauer, and Limited. All have a 210-horsepower 4.0-liter V6 engine. Optional on Eddie Bauer and Limited is a 292-horsepower 4.6-liter V8. V6 models have a 5-speed automatic transmission; V8s have a 6-speed automatic. Maximum towing capacity is 5,375 pounds for the V6 and 7,285 pounds for the V8. Available safety features include ABS, traction control, antiskid system, curtain-side airbags, and front-side airbags. Offered on all is a 3rd-row seat for 7-passenger capacity; it's available with a power-folding feature. Explorer's capless fueling system allows owners to fill their fuel tanks without having to remove a gas cap. Ford's Sync voice-activated cell phone and MP3 player control system is available. The available navigation system includes real-time traffic alerts, weather, gas prices, sports, and movie information. Ford re-trims the Explorer for sale as the Mercury Mountaineer.
