In the video recorded by AmericaJR, Lentz refers to the turbocharged LF-NX Concept that was on display at the Tokyo Motor Show, but comparing this image to our gallery from Tokyo, there are clear differences between the two vehicles. These include the toned-down shape of the spindle grille, lower fascia crease and door mirrors as well as a headlight design that more closely resembles that of the 2014 IS sedan and the newly introduced RC coupe. From what we can see of the rest of this image, the NX should retain some of the LF-NX's angular side body creases. The vehicle you see above basically looks ready for production.
If this is in fact the NX, then reports of a Geneva debut for the luxury crossover seem even more accurate. The entire video is posted below, but the NX comes on screen around the 10:40 mark.
