If the new Lincoln MKZ bodes well for the future of the brand, the same cannot be said of the Navigator, the sumptuous Ford Expedition clone with which it shares its major mechanical components. Its big 5.4L V8 develops 310 horsepower and the gigantic cargo space ranges from 1,206 to 3,704 litres. This all-wheel drive mastodon has a towing capacity of 2,684-kg (6,000 lbs.).
