I clocked 260 with my E90 330d "stock" whether it was "true clock speed" I don't know but went past the 250 normal governer, on the Coast though and not one car in sight on a long stretch!!
As I said before we drive these cars and mod them etc etc ..... for what, Germany a "thinking" country has the Autobahns so as if you spend large money for a high performance car you can actually use it in safety :cartel:
