The RX 350 has all the standard equipment one would expect from an SUV of this class. Leather upholstery, a power rear liftgate, a sunroof and 17-inch aluminum wheels are just the beginning of an impressive list of amenities. The 3.5-liter V6 has good low-end torque for hauling, and sufficient usable horsepower to deliver swift highway performance. It also delivers smooth operation with minimal droning under heavy load, contributing to the SUV’s excellent repair and reliability records. The all-wheel drive system uses a viscous limited-slip center differential that can send more power to the wheel that has traction under most circumstances. It can even shift power between the front and rear axles to better distribute torque as needed. Safety features include front seat-mounted side air bags, front-row curtain and side-seat knee airbags and a driver’s-knee air bag. Standard Vehicle Stability Control (VSC) and Hill Assist Control to prevent the car from rolling backward on inclines are also included
