E63S 4th before the M5 5th. Large gap in the lap time (M5 : 1:35.313 ; E63S : 1:33.122), which is really surprising compared to all other tests done to date.
Agreed, over a 2 second lap time difference is certainly outside any test I've seen so far. Furthermore, those acceleration numbers for all the cars tested are without doubt the slowest I've seen anywhere obviously not helped by the 'relatively' high midday temperatures and sufficiently loose tarmac as stated in the article.
