New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The QX55 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The RX’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

The QX55’s corrosion warranty is 1 year longer than the RX’s (7 vs. 6 years).

The QX55’s 2.0 turbo 4-cylinder produces 12 lbs.-ft. more torque (280 vs. 268) than the RX 350’s standard 3.5 DOHC V6.

For better traction, the QX55 has larger tires than the RX (255/45R20 vs. 235/65R18).

The QX55’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the RX’s standard 65 series tires. The QX55’s tires are lower profile than the RX’s optional 55 series tires.
