Lexus' so-called “L-finesse” design language, highlighted with bold, strong edges and capped with the inverted “spindle grille,” has drawn attention ever since its debut on the 2013 GS. The new Lexus LF-NX concept crossover, which debuts at the upcoming 2013 Frankfurt motor show, has more surprises. Lexus claims the LF-NX concept previews both a future compact crossover model, as well as a future evolution of the L-Finesse design theme. Press materials describe the concept's exterior as “distinctive” and “sculpted.” The latter certainly rings true, as the LF-NX's sheetmetal boasts more geometric planes. Lexus' release suggests the LF-NX uses a “strong” interpretation of the spindle grille, which apparently equates to it stretching from hood to front skidplate. Two large, vertical air intakes flank the grille, and give way to the bugling front fenders. A triad of slim, LED headlamp elements are placed beneath thin eyebrows, while Lexus' signature L-shaped LED running lamps are mounted separately from the headlamp assemblies, much like the most recent IS sedan. The LF-NX's tail makes its nose look conservative. An inverted triangular light catcher placed just above the rocker sills bumps into the crossover's flared rear fenders, which end abruptly just before the bumper. Lexus' press materials praise this “sharp, vertical cut line,” which helps form arrow-shaped surfaces that wrap up and into the rear hatch, echoing the long, slender tail lamps. – SG
