We're still a couple weeks away from the Detroit Auto Show, but the Lexus LF-Lc concept has leaked thanks to the crew at Road & Track and their YouTube account.

We still don't know much about Lexus' Detroit-bound concept, but the swoopy coupe combines some of the more emotive elements of the LFA, along with the grille of the LF-Gh concept that eventually formed the basis of the Lexus GS. The massively elongated hood terminates with headlamps that plummet deep into the air intakes and a more extreme grille than that found on the Predator-esque fascia of the Gh.

With an "Lc" designation, this could signal Lexus' intention of building an LS-based coupe to take on the likes of the Mercedes-Benz SL, but until the official curtains are pulled in Detroit, we'll have to wait and see.

In the meantime, check out the video after the jump for the unintentional early reveal. As long as it stays on YouTube...
