Lexus teases new luxury concept for Tokyo

Lexus certainly doesn't want to reveal any secrets about the concept premiering at the 2015 Tokyo Motor Show on October 28. The company's teaser simply shows a squinting LED headlight with a devilish, hooked tail running underneath. Plus, the dearth of descriptive text merely says that the vehicle is a "vision of progressive luxury." While there's not much useful info, some recent rumors might hint at what we're looking at.

One possibility is the concept providing a peek at the next-gen LS because the rounded, current generation no longer matches the rest of the Japanese brand's sharper styling. Reports earlier this year even suggest a fuel-cell version under development as part of a hydrogen push in Japan. This range-topping model could potentially weigh even less than the current hybrid by adapting the powertrain from the Toyota Mirai.

The less likely alternative is a concept pointing the way towards Lexus' second flagship. Reportedly a successor to the SC, the model isn't rumored to debut until the 2016 Detroit Auto Show. Still, the company could shuffle things around, and we look forward to seeing what's worth being so coy about in Tokyo in just a few days.
