The Lincoln Navicross is a concept car that was built by Lincoln. The Lincoln Navicross was first unveiled at the 2003 Detroit Auto Show. The vehicle features styling similar to that of the Zephyr and MK9 concept car. Two chrome accent bars placed on the vehicle's left and right front fenders run the full length of the vehicle as in the MK9 and Mark X concepts. The vehicles features Lincoln's hallmark waterfall grille with the Lincoln emblem at its center. Much like the MKS concept models presented at the 2006 Detroit Auto Show, the Navicross features suicide doors which according to Ford, give "unrestricted ingress and egress to the luxurious interior." Suicide doors also appeared in the Continental concept car and the MKS concept car.
