Exemplifying the shape of things to come from the automaker, the 2013 Lincoln MKZ (www.lincoln.com) displays a smooth, flowing design that yields aesthetic and aerodynamic benefits. The sedan’s sweeping profile and ample greenhouse are enhanced by a retractable panoramic roof that is one of the largest openings on any sedan. The car’s Active Noise Control (ANC) provides a quiet ride by canceling or reducing unwanted frequencies. Power options range from an intriguing 2-liter electric hybrid engine to an estimated 300 hp, 3.7-liter V-6. The front-wheel-drive and hybrid models likely will start at about $36,000 and be available toward the end of this year.
