Vehicle details The 2016 ES w/ Lexus Safety Sense + earns a 6/6 points (Superior Rating) for its Front Crash Prevention in the IIHS tests. This bodes well for the Gen 4 Prius as it will have TSS P, same as LSS+ but without Lane Keep Assist (Lane Departure Alert is in both packages). Basically, this confirms Lexus' press release.
