We drove an all-wheel drive version of the 2007 Lincoln MKX on a 150-mile route that included some city and freeway driving, but was highlighted by a long stretch on the famous Blue Ridge Parkway. The scenery is breathtaking, with seemingly endless forests astride the border between North Carolina and Tennessee in the Great Smoky Mountains. The route also included a portion called The Dragon’s Tail, an 11-mile long tract of single-lane tarmac with 312 turns. The low-light visibility, as well as the narrow and winding shoulderless road gave us a perfect opportunity to experience the MKX’s adaptive headlamps, to power through tight corners at speed, and subject this new model to hard braking.
