Lexus has released a single teaser image of a new concept car making its world debut at the 2013 Frankfurt Auto Show next month. No details were released with the teaser, so we can only guess what the Japanese automaker has in store.

The teaser shows the headlight of the concept as well as part of its grille. The design of the light resembles the design used on the 2014 IS sedan as well as the LC-CC concept from 2012, which served as a preview of the latest IS as well as the automaker's upcoming RC coupe.

The new concept may be a preview of another Lexus model still in the works: a compact crossover tipped to be called the NX. However, a concept version of the NX is thought to be on track for a reveal at the 2013 Tokyo Motor Show in late November. This means that the teaser is likely to be for a new coupe concept that will preview the aforementioned RC.

The RC is essentially an IS coupe and is expected to land in showrooms next year as a 2015 model. It will compete against the Audi A5 and BMW 4-Series and will spawn an RC F performance variant. Lexus has major motorsport ambitions for the RC and has already announced that a version of the car will compete in Japan’s Super GT touring car series.

We should find out exactly what Lexus has planned soon as the Frankfurt Auto Show gets underway on September 10. Stay glued to our dedicated show hub for our latest updates.
