For this inaugural test group, IIHS evaluated 74 luxury midsized cars and SUVs from the 2013 and 2014 model years. Seven earn the Superior rating, including the Cadillac ATS and SRX, Mercedes-Benz C-Class, Subaru Legacy and Outback wagon, and Volvo S60 and XC60. The Institute found that Subaru’s EyeSight system performed the best and avoided hitting the test target at both speeds. The Cadillacs avoided the target at 12 mph and reduced the speed in the 25 mph test by 15 mph in the ATS and 19 mph in the SRX.
Six additional models earn the Advanced rating: The 2014 Acura MDX, Audi A4 and Q5, 2014 Jeep Grand Cherokee, Lexus ES, and 2014 Mazda6. The Volvo S60 and XC60 drop down to the Advanced rating when they have just City Safety, and not optional Collision Warning with Full Auto Brake and Pedestrian Detection.
Twenty-five other models tested by IIHS earn the Basic rating and include: Acura ZDX, BMW 3 Series and X3, Chevrolet Equinox and Malibu, 2014 Dodge Durango, Ford Edge, Explorer, Flex and Fusion, GMC Terrain, Honda Accord and Crosstour, Infiniti EX, FX, JX, Q50, QX50, QX60, QX70, Jeep Cherokee, Lincoln MKT, MKX, and MKZ, and Mercedes-Benz GLK-Class and M-Class. The Acura MDX, and Cadillac ATS and SRX scores drop down from Superior to Basic when they are equipped with forward collision warning systems only and not higher rated systems that incorporate an automatic brake feature. The Durango, Cherokee, Infiniti, Lexus, and Mercedes-Benz models listed above earn basic ratings because IIHS has not yet tested their systems that include automatic brake.
“Front crash prevention systems can add a thousand dollars or more to the cost of a new car. Our new ratings let consumers know which systems offer the most promise for the extra expense,” David Zuby, IIHS chief research officer, said.
