Volvo’s crash avoidance technology, part of its future self-driving technology, contributed to the brands’ four models sold in America to gain the highest safety recognition.

Four Volvo cars made the Insurance Institute of Highway Safety Top Safety Pick+ grade in this year’s honors list: the S60, V60, S80 and XC60. Volvo Cars was the only European brand with more than two models on the list.

The newly revealed XC90 SUV was not launched in time to participate; Volvo did not explain why the XC70 was not tested.

Some of the vehicle tested, like the S60, are powered by the company’s new Drive-E powertrains which have been designed to integrate hybrid components in the near future.

“Volvo Cars’ commitment to real-life safety and our Vision 2020, which states that no one will be killed or seriously injured in or by a new Volvo car, underlines our approach towards continuous improvement in this field. At Volvo Cars we focus on real-life safety – reflecting the many and varied causes and results of car accidents. It is of course a wonderful thing that we receive such honors and recognition for our advanced safety innovations from leading safety institutes,” said Dr. Peter Mertens, Senior Vice President Research & Development at Volvo Cars.

The Tops Safety Pick+ award criteria have grown tougher in the last year, with increased demands around the standard for front crash prevention. Volvo explained to meet the new criteria cars making the Top Safety Pick+ grade must offer the ability to stop or slow down without driver intervention before hitting a target in IIHS tests at 12 mph, 25 mph or both.

Volvo Car’s front crash avoidance technology, City Safety, which is standard in all new Volvos, is said to help detect and brake automatically to mitigate or prevent a car to car rear end collision without driver intervention.

Volvo stated its City Safety technology has been shown to reduce insurance claim frequency by 16 percent.

“Volvo Cars has received much recognition during its long history of safety driving the industry forward. A perfect example of this is the three-point safety belt, invented at Volvo in 1959 and now used globally by all car makers. With the sales start of the All-New XC90 in 2015 Volvo Cars will offer the world’s most advanced crash avoidance technology as standard,” said Thomas Broberg, Senior Safety Advisor at Volvo Cars.
