The RX got a 2016 makeover, with avant-garde exterior styling and advanced safety features. Its 3.5-liter V6 is now linked to a new eight-speed automatic, delivering ample power and a commendable 22 mpg overall. The fuel-thrifty 450h hybrid gets an excellent 29 mpg overall. Inside, the RX is very quiet and well-finished. Ride comfort is plush whether you get the base car on 18-inch tires or more uplevel versions with 20-inch tires. Handling, however, is ponderous and devoid of any sporty feel, but ultimately secure. The mouselike controller and interface require a steep learning curve. Rear passengers get lots of leg and knee room. For 2017, the Lexus Safety System+, which includes forward-collision warning, automatic emergency braking, lane-departure warning, and adaptive cruise control, is standard.
