Positioned decrease in the array will be two extra hybrid solutions: the RX450h+ and a foundation-product RX350h. The 450h+ will reportedly gain motivation from a naturally-aspirated 2.5-liter gasoline motor. Aided by an electric powered motor and lithium-ion battery, it will serve as the plug-in hybrid by-product. The 350h will use the exact same engine as the 450h+ and, while it will get an electric motor, will do without having the lithium-ion battery.
Last of all, the naturally-aspirated 3.5-liter V6 will be replaced with a 2.4-liter turbocharged device, most probably borrowed from the smaller sized NX. The 275-horsepower 4-cylinder motor makes 317-lb-ft of torque, not far off the outgoing 295 hp RX350.
