The LINCOLN MKZ comes in one trim level. It's powered by a strong, 263-hp V6 with a six-speed automatic transmission. Front-wheel drive is standard. All-wheel drive is available. Safety features that come standard: side-impact air bags in front; curtain-style head protection airbags for all outboard positions; traction control and anti-lock brakes with electronic brake-force distribution, which distributes braking force to the tires with the most grip. For 2007, the LINCOLN MKZ replaces the LINCOLN Zephyr.
