This new model looks larger than the current RX, like the wheelbase has been stretched, which would likely explain reports that the company was looking at an optional third-row for the mid-sizer. Aesthetically, the Lexus spindle grille is easy to spot, as are its aggressive headlamps. It's unclear based on these images if the RX will adopt the same styling statement seen on the RC, IS and NX, with sharp LED running lamps mounted below the actual headlights, but it certainly seems likely.
Besides the design changes, our spies report that Toyota will be working hard to shed weight, likely through the use of aluminum for the doors, hood and rear hatch. Underhood, expect the typical combo of a gas-powered six-cylinder as well as the V6/hybrid setup found in Lexus' 450h models.
As for when we could expect to see the next-gen RX, your guess is as good as ours. Geneva is, as always, a candidate, as is April's New York Auto Show. Of course, should we confirm a debut at either show, we'll be sure to let you know. Stay tuned.
