M3 Top Speed. 11 jun 20 2006. 3541 mph 5666 kmh top water speed.
The british service name stuart came from the american civil war. Truth be told the m3 wasnt really doing that kind of speed as the cars speedometer seems to be hilariously inaccurate. This 155 mph top speed can be achieved quite easily by the e46 m3 and many owners looking to stretch the legs of the s54 motor opt to have this electronic limit removed or coded out.
On paper the m4 is only 27 more powerful than the e92 m3.
From the factory the m3 is restricted to 155 mph electronically as most bmws are. Thereafter it was used by us. 200 mi 320 km maximum speed. Top speed remains locked at the usual 155 mph but you can increase that to 180 mph with the optional bmw m drivers package.
