Lexus and its parent company Toyota are pioneers when it comes to hybrid technology. For years, the brand has offered hybridized model variants including the Lexus RX luxury SUV. But according to several sources, the 2023 model will eschew all conventional powertrains for a trio of hybrid models.

This is according to Japanese publication Creative311, the news outlet claiming that the all-new RX will gain a plug-in hybrid derivative. The hybrid models will be offered in three different setups. The report notes a new RX500h will become the new range-topper above the RX450h. This model will be powered by a 2.4-liter, four-cylinder, turbocharged engine with an electric motor.

Positioned lower in the range will be two more hybrid options: the RX450h+ and a base-model RX350h. The 450h+ will reportedly gain motivation from a naturally-aspirated 2.5-liter gasoline engine. Aided by an electric motor and lithium-ion battery, it will serve as the plug-in hybrid derivative. The 350h will use the same engine as the 450h+ and, although it will receive an electric motor, will do without the lithium-ion battery.

Lastly, the naturally-aspirated 3.5-liter V6 will be replaced with a 2.4-liter turbocharged unit, most likely borrowed from the smaller NX. The 275-horsepower four-cylinder engine produces 317-lb-ft of torque, not far off the outgoing 295 hp RX350.

No mention is made of possible power outputs for the hybrid models but, if the rumors are to be believed, expect Lexus to improve horsepower and torque figures for the luxury SUV. The current generation of the BMW X5 rival has been around since 2015 and while it's still a capable car, it has been left lagging behind more competent rivals for some time now, despite several updates.

The new RX will certainly aid the company in strengthening its US sales as it always remained a popular choice among SUV buyers. Expect the all-new derivative to arrive in 2023, refreshed and ready to take on the best Europe's luxury carmakers have to offer.
