The organization awarded ‘advanced’ or higher ratings to 21 of 24 models that were included in the latest round of evaluations, which focused on large cars alongside a few midsize cars and SUVs. The latest test follows earlier rounds that tested
“We are already seeing improvements from automakers since the initial launch of our ratings last September,” said IIHS research chief David Zuby. “BMW and Lexus, for example, have added more braking capability to their systems, which has paid off in higher ratings.”
Ratings are based on whether a model has autobrake capabilities and, if so, how effective the system is at reducing speed or completely stopping a vehicle as it approaches an obstacle at 12 mph and 25 mph. Models that both warn a driver and provide significant speed reduction earn the ‘superior’ rating, while warning-only systems without autobraking receive a ‘basic’ qualification.
Perfect scores were earned by BMW’s 2014 5-Series sedan and X5 SUV, Hyundai’s 2015 Genesis sedan and Mercedes-Benz’ 2014 E-Class sedan. All four either entirely braked to a stop or rolled into the obstacle at just a few mph when approaching from 25 mph.
The organization praises Acura, Mercedes-Benz and Volvo for providing front-crash protection technology as standard equipment on some models. General availability as optional equipment from all major automakers has also doubled since 2012.
“Sorting through the various trade names and features can be confusing, even if you’re looking at models from the same manufacturer,” Zuby concluded. “Before buying, consumers should consult the IIHS ratings to find out if the specific model they are considering comes with a top-rated front crash prevention system.”
