So the LF-LC (who picks these names?) is 2+2 sporty coupe. Lexus claims that it's "showcasing the future design direction for Lexus with an emphasis on a driver-focused vehicle" and "displays the new Lexus design language in its bold interpretation of the signature Lexus spindle grille and rear architecture. Sumptuous curves blend smoothly into dynamic angles, creating an inviting display of lines, shadows and corners."
Sadly for us, there are not many details about the hybrid drivetrain or fuel economy. All we know is that it's the "Advanced Lexus Hybrid Drive", which probably means that it's the same technology that can be found in other Lexus hybrids. I'm hoping that if it ever becomes a production model, that it will at least have a plug-in option; no so much because I expect tons of them to sell and that it'll make a big difference to the environment, but because if Toyota/Lexus engineers are working on these technologies, we'll see them appear more quickly in cheaper and more mainstream models where they can really make a difference (don't get me wrong: It's better to walk, bike, or take transit, but as long as there are cars out there, they should be as clean as possible).
There isn't too much else to say about it, so let's look at some pretty pictures!
