the RAV4. Another small overlap test was conducted on a number of vehicles, including a 2015 RAV4, but was conducted on the passenger side instead. The RAV4 fared the worst and would have received a "poor" rating if the IIHS were to provide ratings for passenger-side protection. The crash test's intrusion was further into the vehicle on the passenger's side than on the driver's side and caused the passenger door to open during the crash. Fifth generation (XA50; 2018) The fifth-generation RAV4 was unveiled at the March 2018 New York International Auto Show. The design was previewed by the FT-AC concept shown at the December 2017 Los Angeles Auto Show. It is built on the same TNGA-K (GA-K) platform as the XV70 series Camry. Both 4-cylinder petrol-powered and petrol-electric hybrid (Hybrid Synergy Drive) variants would remain available. Development of the model was led by chief engineer Yoshikazu Saeki. Built on the GA-K platform, the unibody chassis of the fifth-generation RAV4 is 57 percent more rigid than the previous generation. The model incorporates a multi-link rear suspension to which is claimed to provide more ideal damping for handling, lesser interior cabin noise, and enhanced ride comfort. For improved forward visibility around the A-pillar, Toyota positioned the side mirrors lower on the doors. The lowered beltline and the enlarged rear quarter glass also increased the side visibility from inside the car. Forward visibility is also enhanced by the positioning of the lower instrument panel and tucked-in windshield wipers. The fifth-generation RAV4 also introduced a newly developed four-wheel drive system, marketed as "Dynamic Torque Vectoring AWD". Claimed to be a world-first adoption, it is a torque vectoring type, which independently distributes torque to the left and right rear wheels according to driving conditions. A disconnect mechanism, marketed as "Rear Driveline Disconnect", is incorporated to transmit driving force only to the front wheels when 4WD is deemed unnecessary. For hybrid models, all-wheel drive model utilized the "E-Four"/"AWD-i" system. The updated system increases the total torque to the electronically driven rear wheels by 30 percent compared to the AWD system used in the previous generation. A new control system allows torque distribution to the front and rear wheels to be changed from between 100:0 to 20:80. A standard AWD system without torque vectoring is also available for petrol models. Markets North America The RAV4 went on sale in the United States in December 2018, while
