Lexus will unveil a more people-friendly version of its RX later this month.

Lexus has confirmed that it will finally debut its long-rumored RX three-row crossover later this moth at the Los Angeles auto show.

Lexus is keeping the details of the three-row RX a secret until the start of the LA show, but the automaker says it will market the CUV as the RX 350L. Lexus plans to eventually introduce a hybrid version of the three-row known as the RX 450L, but that model won't be making an appearance at the LA show.

It's believed that the RX 350L will share a common wheelbase with the standard RX. In order to accommodate the third row, Lexus will stretch the rear end of the RX by a few inches. Although that solution probably won't result in the roomiest third-row in the segment, it should at least significantly enhance the crossover's cargo carrying abilities.

Powertrains should mirror that of the RX 350. That means the RX 350L will likely come with a 3.5L V6 rated at 295 horsepower. Front-wheel drive will be standard while all-wheel drive will be available as an optional extra.

Although Lexus's lineup includes a pair of three-row SUVs — the GX and LX — the RX 350L represents the brand's first car-based utility vehicle with seating for seven. The RX 350L will finally give Lexus a viable alternative to vehicles like the Audi Q7, and comes at a time when utility sales are booming.

Look for the 2018 Lexus RX 350L to go on sale next year with an estimated price of around $45,000.
