A week after spy shots of a mysterious Lexus LF-A were snapped at the Nurburgring, Lexus->ke2181 brought out a second model sporting the same features with a different color scheme which was spotted in the same vicinity.

Let the speculation begin.

Instead of the bright blue finish that we saw last week, this one, courtesy of a video captured by a YouTube user, comes dressed in bright green and appears to be a little more subdued version of the other model. Take for example, the exhaust. The blue version sported a quad exhaust set-up in the rear whereas the green version has the standard three-pipe, triangular exhaust.

Another distinguishable difference are the letters on the flanks of both cars, just above the side sills. This model has "AD-B" written on it whereas the blue model carried "AD-A" on it. If those are code words for a prototype model like we speculated a week ago, then Lexus must be preparing a final swan song - or two - for their mighty super car.

Keep tabs here for updates; we're betting our mortgages that this won't be the last time we're going to here from these two mysterious LF-As.
