The 2010 Lincoln Navigator is a luxurious full-size SUV hailing from Ford's luxury brand, Lincoln. This 3rd-generation model is known for its mighty stance and opulent interiors. Under the hood, a 5.4-liter V8 engine sends a healthy 310 horsepower to its rear wheels, with an optional four-wheel-drive system. A six-speed automatic transmission is standard across the board. Just one trim is offered, but it's exceptionally well-equipped, boasting leather upholstery, heated and ventilated front seats, power-folding third-row seats, a power liftgate, and dual-zone automatic climate control. The infotainment system features a voice-activated navigation system, a THX II-certified 14-speaker audio system, and Sirius satellite radio. Comprehensive safety features include a reverse sensing system, front-seat side airbags, three-row curtain-type airbags, and the much-appreciated Ford's MyKey system which allows parents to limit the vehicle's top speed and stereo volume for their young drivers.
