Aside from the taillights, there are a couple other details that have been revealed. The car's retractable rear spoiler is seen in action. There also seem to be faux body panels covering the front and rear fenders. Upon very close inspection, you can see some odd lumpy portions in these areas that don't follow the lines of the car, and nearby are some faint seams. We can infer that the actual height of the front and rear fenders will be a bit lower and more understated than they appear in these photos.
Previous spy photos have shown that there is a convertible version in the works that will likely be released around the same time as, or soon after, the coupe. The car will use the Panamera platform, and it will likely be offered with 8- and 12-cylinder engines, as it is now.
