Mystery Lexus LFA AD-X Prototype Spotted!

A new Lexus LFA prototype has been spotted at the Nürburgring in Germany:

Lexus LFA AD-X Side
Lexus LFA AD-X Rear

An AD-X decal is clearly visible on the side of the LFA, which makes sense — there was an AD-A & AD-B spotted earlier this year, and the similarities between the prototypes are obvious.

Here’s a head-on comparison with the AD-A & AD-X:

Lexus LFA AD-A Prototype
Lexus LFA AD-X Front

It’s been confirmed that AD-A & AD-B were advanced development one-off vehicles, and not an indication that there’s a new special edition LFA planned — it’s likely the same story with this new AD-X.

(Big question: where are prototypes AD-C through AD-W?)
