(these are likely referencing the 250kph/155mph limiter)

The guy who hit "186" got a downhill start to 70mph, then took another 1.25 miles to reach top with no limiter.

Mechanical top speed is 194, not counting for drag http://www.enormouslysideways.net/calc.html

Drag limits the top speed to 181-185 (330hp DC spec/ 350hp MB spec) Horsepower & Aero Drag Calculator

Full Eurochaged power package (407hp) will reach the mechanical limit of 194. (= drag max as well 194.7mph)

Realworld conditions are going to keep you from reaching max theoretical most of the time (open straight road length, driver and cargo weight, wind, traction/ rolling resistance, etc)
