In the shadowy image of the car's flanks (above) it seems as though Lexus has given its crucial SUV its most radical redesign yet, with an interesting roof design, a new side window interpretation and the heavy use of contrasting surfaces.
The new RX's tail-lights sports L-shaped light bars, similar to those seen on other Lexus models. At the front, it's more than likely that the SUV will sport a variation of the brand's spindle grille design.
Toyota's luxury brand has yet to reveal any concrete details about its new SUV, but it's reasonable to expect that the new car will feature V6 and hybrid drivetrain options at least.
The RX is a critically important car for Lexus in its largest market, the USA. Last year, despite being six years old, the RX recorded its best sales since the mid-noughties. With 107,490 RX SUVs finding new homes in the US in 2014, the RX was responsible for almost 35 percent of the marque's sales.
In Australia, the RX is almost as important for the brand's fortunes. Last year, the RX accounted for 1866 of the brand's 7000 sales — a smidge under 27 percent. In 2013, the 2188 RX SUVs sold by Lexus Australia constituted almost 32 percent of the marque's volume.
The fourth-generation RX will have its public debut on April 2, Australian time, at the New York motor show.
