The RX PHEV is the most expensive model in the lineup and features a 2.5-liter inline-four gasoline engine and an estimated electric range of 35 miles.
In 2024, Lexus will offer a third hybrid variant of its RX SUV. In addition to the RX350h and RX500h F Sport Performance hybrids already available, a new plug-in hybrid model, the RX450h+, has been added to the lineup. The plug-in hybrid is mechanically identical to the smaller NX450h+ and reportedly has a range of 35 miles on electric power alone.
The RX450h+ is equipped with the same all-wheel-drive system as the NX450h+ and Toyota RAV4 Prime, which consists of a naturally aspirated 2.5-liter inline-four and three electric motors. The 18.1 kWh battery pack can be recharged using the onboard 6.6 kW charger and a 240 V outlet in about 2.5 hours. Its total output of 304 hp is just a hair higher than that of the other models’ 302 hp. However, Lexus claims a 6.2-second 0-60 mph time for the larger RX, making it slower than those smaller PHEVs.
The RX450h+ has the highest starting price of any RX model, at $70,080. It has a head-up display, leather upholstery, heated and cooled front and rear seats, and a panoramic sunroof as standard equipment, just like the Luxury trim level does for vehicles with less powerful engines.
With hybrid power, it achieves 35 mpg combined (just 1 mpg less than the RX350h) and 83 MPGe (including electric driving) as rated by the EPA. Lexus says dealers can expect to have the RX450h+ in stock by year’s end.
