Lexus is said to be testing a series of their LFA supercars and this is the third car spotted at Nurburgring bearing the code AD-X at its fender. This LFA AD-X looks to be aggressive with the front bumper lip and the little fin to increase downforce at the front. Quite similar to the Lexus LFA Nurburgring Edition. And the red stripe with red rims remind many of the classic Porsche 911 Carrera RS.
Although it is said that these ADs are mainly for testing on technical purposes only. So there might be little hope for some special edition LFA.
