Charoudin also makes an important point about all of these times: cars like the ZR1X and ZR1 might not be the ultimate when it comes to repeatable results. He calls out Porsche and some of its high-end RM-tuned examples in the same way. Both are so extreme in their engineering that they might not be able to repeat their lap times back to back.

Back in December last year, Ford announced that its new-but-not-a-diesel GTD had set a Nürburgring lap time of 6m 57.6s, making it the fastest American car ever to lap the Green Hell. Then, in May this year Ford went back to Germany and shaved 5.5 seconds off that time for a new record of 6m 52.072s.
