The Lincoln MKS is a replacement for Lincoln's classic Continental sedan. The Lincoln MKZ is another replacement for an old model; its name stands for Mark Zephyr, after the discontinued Lincoln Zephyr.
The Lincoln MKT and MKX model designations refer to form factors, just as the name MKS does. MKX is a crossover SUV, and MKT is a trucklike SUV model. Lincoln's popular Navigator SUV does not share this naming scheme, and remains designated the Lincoln Navigator as of 2015.Learn more about Car Makes & Models
