The redesigned RX 350 features a revised 3.5-liter 2GR-FE V6 engine producing 275 horsepower (205 kW) with a wider power curve, it remains ULEV-II certified and now uses a six-speed automatic transmission with sequential shift. A double wishbone rear suspension setup replaces the previous MacPherson strut design for improved handling and greater cargo space, while an optional Sports Package adds a performance-tuned suspension. Both non-hybrid and hybrid models continue in either front or all-wheel drive configurations, with the all-wheel drive system gaining Active Torque Control for greater efficiency, and all models are built off the new midsize flexible K-platform. American RX 350 sales began in February 2009 as a 2010 model.
