With both agencies changing their formulas for crash-test scores, the Lincoln MKZ no longer earns a perfect 10 for safety.In the 2010 model year, the MKZ earned five-star front-impact crash scores from the National Highway Traffic Safety Administration (NHTSA). Now, under the new equation, the MKZ drops to four stars overall, with a three-star score for frontal impacts.
Meanwhile, the Insurance Institute for Highway Safety has also updated its rankings to incorporate a roof-crush rating. It still calls the MKZ "good" in its impact and rollover tests, and has once again named it a Top Safety Pick for 2012.
Every MKZ comes with standard airbags, anti-lock brakes and stability control. It also gets a rearview camera, blind-spot monitors, and parking sensors. Ford's MyKey system is wired in as well: it lets drivers configure the car for pre-set speed limits and stereo volume levels, which Ford says lets younger operators drive more safely.
