A 2011 redesign made the S60 much nicer, with agile handling and a taut, steady ride. The standard T5 is pretty lively, but the top-level T6 is quicker and more refined. Among the advanced safety gear is an innovation Volvo called "City Safety". This helps prevent low-speed crashes by scanning the road ahead, sounding an alarm and applying the brakes if you are likely to collide with the car in front of you. This feature has since spread throughout the industry. Today, it is known as forward collision mitigation. The T5's five-cylinder engine can sound gruff, but provides lively acceleration and respectable fuel economy. The interior is quiet, neatly finished and front-seat comfort is excellent. However, the rear seats are best suited for children and trunk capacity is meager.
