This new midsize SUV replaces the MKX for 2019, adopting all the modern design elements of Lincoln's next-generation models and a name that captures the spirit of travel like the Navigator and Continental. Two turbocharged engines can find their way under the hood of the Nautilus: a 245-horsepower four cylinder and a 335-horsepower V6. A key upgrade is the Co-Pilot360 system essentially allowing semi-autonomous driving, with available evasive steer assist to help avoid collisions.
