The M5 is a real disappointment. Is was usually to most powerfull in class. Now it is no more, worst thing, it is heaviest in class. Now there is a new most powerful wagon in the world: 585 PS, it beats the previous RS6.
Mercedes E 63 AMG 4-Matic Performance
0-100 km/h in 3.6 sec!!!!!!
That is even faster than new RS6 and Panamera Turbo S. Also, front/rear power distribution is 33/67.
Such a shame M5 is no more KING, it even doesn't sound good.
