- The Lincoln MKS and the BMW 5 Series are the "worst performers" among large luxury sedans evaluated by the Insurance Institute for Highway Safety in a new round of crash tests.
- A "Poor" rating applies to 2009-'15 Lincoln MKS sedan; a "Marginal" rating applies to the 2011-'15 BMW 5 Series.
- The 2014-'15 Infiniti Q70 and the 2013 Infiniti M achieved a "Good" rating in the Institute's small overlap front test.
The cars were put through the Institute's small overlap front test, which gauges how well the driver is protected when the front corner of a vehicle collides with another vehicle or a fixed object, such as a tree or utility pole.
A "Poor" rating in the test applies to 2009-'15 Lincoln MKS sedan; a "Marginal" rating applies to the 2011-'15 BMW 5 Series.
"The Lincoln MKS is a safe vehicle, equipped with driver assist and advanced safety features for both occupant protection and crash avoidance, with a structure designed to manage crash energy under a variety of crash conditions," wrote Kelli Felker, a Ford spokeswoman, in response to an Edmunds query on Thursday.
She added: "Safety is one of the highest priorities in the design of our vehicles. Our cars and trucks consistently meet or exceed government safety standards in the countries in which they are sold".
Ford prioritizes tests that focus on occupant protection and provide real world safety benefits.
The Institute said the "driver space was maintained reasonably well" in the test of the Q70. But it noted that "the performance of the Lincoln MKS in the small overlap test couldn't have been more different.
"The driver space was severely limited after the crash, with the structure pushing in as much as 12 inches," it said. "The dummy's head barely contacted the front airbag before sliding off the left side and hitting the instrument panel."
The Institute noted that the BMW 5 Series "performed somewhat better, earning a Marginal rating."
"Like the MKS, the 5 Series also saw as much as 12 inches of intrusion," it said. "However, there was considerably less intrusion in the upper interior. The dummy's movement was well controlled, with both the front and side airbags doing their jobs."
Tests of the Audi A6, Cadillac CTS and Lexus GS are on hold because the manufacturers told the Institute they are making changes to improve small overlap protection. These models will be tested early next year.
Edmunds says: Some critical safety news for car shoppers in the market for a luxury car.
