Lexus is only building 50 copies of the Nürburgring Special Edition, and to make it worth the extra $70K they're adding a whopping ten additional horses to the 4.8-liter V10 for a total of 562 HP. The package also includes a larger spoiler and wings, as well as dive planes up front, all of which are carbon fiber and designed to keep your now $445K Lexus planted to the ground. They've also thrown in the standard "sports tuning," new wheels-and-tires and a reconfigured transmission for slightly quicker shifts.
If the price seems a little unimpressive for you, the final carbon fiber nail in the platinum coffin is the matte black paint job for $20K. If you ever see one of these on the street feel free to point, laugh and loudly exclaim to anyone within audible range that "This moron paid $20,000 for paint!"
Lexus simultaneously sent out a press release announcing they've chopped the prices on their F-sport suspension offerings. When you charge $20K for paint you can afford to be generous.
