You could hardly accuse the latest Lexus RX SUV of being dated, but that hasn't stopped the premium Japanese brand from giving it some automotive botox.

Though there's no official information available yet, the pictures you see here are taken from a leaked Japanese brochure.

It shows a redesigned front bumper that adopts the company's new 'spindle' grille design, as seen on the latest GS sedan, along with new headlights that incorporate LED daytime running lights.

Other parts of the brochure show that the new SUV also sports redesigned alloy wheel designs and new taillight graphics.

The bottom picture here also shows an F Sport variant that's joining the range for the first time.

This sportier option might not mean any extra ponies beneath the bonnet, but it does bring a unique body kit with a bolder front bumper with honeycomb inserts, body spoilers and bigger rubber.

While the new RX doesn't look markedly different on the inside, they have thrown in a new steering wheel, revised trims and, reportedly, a back seat entertainment system that buyers will albeit have to pay more for.

It's unlikely that Lexus will make any alterations to the engine line-up, which includes the petrol-powered, 204kW RX 350 and petrol-electric RX 450h hybrid with a system output of 220kW.
