It is expected to arrive at Lexus dealerships later this year.
The RX 350 is expected to be larger, a strategy that will separate it in terms of size and price from the recently introduced 2015 Lexus NX 200t SUV, which shares a platform with the smaller Toyota RAV4.
Car shoppers should expect the redesigned RX 350 to use an extensive amount of lightweight materials to boost fuel economy. It will continue to share a platform with the Toyota Camry and Toyota Avalon, industry sources said.
The RX 350 may be stretched a bit to accommodate a third-row seat, but Lexus has not confirmed whether seven-passenger seating will be offered. The model has been a five-seater since its inception in 1998.
As for styling, Lexus is not expected to mess with success. The RX 350 has been Lexus? No. 1 selling model for years, accounting for about 35 percent of total Lexus sales last year. The styling will be evolutionary rather than revolutionary.
As with all redesigned Lexus models, a bit more pizzazz may be injected into the styling, particularly in the spindle grille, a predominant styling cue on new Lexus models.
Edmunds says: The Lexus RX 350 has always been a perfect combination of family-style practicality, carlike comfort and a top-notch ownership experience. A third-row seat would only add to its long list of attributes.
