The Lexus LF line is a series of concept cars built by Lexus, the luxury vehicle ivision of Toyota Motor Corporation. The "LF" stands for L-finesse, a new design direction by Lexus. The new design language of L-finesse was first introduced on the LF Series concepts and has now extended to all new vehicles in the Lexus lineup. The LF Series vehicles include three coupes/convertibles, the LF-A, the LF-A Roadster, and the LF-C, two sedans, the LF-S and LF-Sh, and one crossover SUV, the LF-X. These vehicles feature new design cues which are emblematic of the L-finesse philosophy of Intriguing Elegance, Incisive Simplicity, and Seamless Anticipation, and are fitted with new vehicle technologies. The first concept vehicle of the LF Series, the LF-X, appeared in 2003. Several of the LF concept vehicles have appeared close to their production counterparts, while the design cues of other LF concepts appeared on more distinctly different production vehicles.
