For over two decades, the LX has been Lexus' preimum flagship SUV in the lineup. The current generation LX is essentially a more posh and luxurious Toyota Land Cruiser. In fact, that has been the case ever since it was first introduced back in 1995 with the LX450. However, that may soon change. Toyota's upscale brand is set to debut a new range topper SUV concept at the upcoming Detroit Auto Show.

Called the Lexus LF-1 Limitless concept, it was penned in collaboration with CALTY design studio, which also designed the Toyota FT-1 concept. By the looks of the teaser photo revealed, it appears to have strayed from the LX's current design language. In fact, it looks more like a crossover rather than the current flagship SUV.

No other details about the LF-1 Limitless concept has been revealed apart from it being 'the next genre in luxury crossover vehicles.' Looking at the photo however, we do see that it has an illuminated Lexus badge below the one piece LED taillight. The design of rear quarter glass together with the trunk and rear window also appear similarly design to that of the current NX and RX crossovers. It also has a uniquely styled split rear wing. In signature Lexus styling, do expect a large spindle grill in front.

Theroetically, should the LF-1 Limitless make it into production, it could likely replace the LX in the lineup as Lexus' new flagship SUV. Should Lexus make the switch, it could mean that the current generation LC200 Toyota Land Cruiser might get a successor as well.

For now, almost everything is still left in speculation. We will have to wait until the doors of Detroit Auto Show open to know more about the Lexus' up coming flagship crossover.
