The 2015 Lincoln Navigator is a luxury full-size SUV that is appreciated for its spaciousness, style and smooth ride. It's powered by a 3.5L twin-turbocharged V6 engine that produces 380 hp and 460 lb-ft of torque, paired with a six-speed automatic transmission. This model is available in both 2WD and 4WD options across two trims: base and Reserve. Key safety features include front and rear parking sensors, a rearview camera, and MyKey which allows parents to limit speed and audio volume for young drivers. The Navigator's infotainment system hosts an 8-inch touchscreen with Sync and MyLincoln Touch, satellite radio, navigation, and a premium 14-speaker surround-sound audio system. For enhanced luxury, the Reserve trim adds upgraded leather, wood trim, and 22-inch wheels. The 2015 Navigator received an exterior facelift, and replaced the previous model's V8 engine with a more powerful and fuel-efficient V6.
