From an article about the BMW M5......

With 507bhp of power, 520Nm of torque, a top speed limited to 155mph and a 0-62mph time of 4.7 seconds, much of the media talk has been about the option to de-restrict the top speed of the M5. BMW say their top management in Germany has taken the responsible ‘high ground’ and stuck to the general industry agreement that 155mph should be the top speed available. However other manufacturers have broken away from this agreement and BMW say they have no power over any customer wishing to have their car de-restricted to achieve the 204mph of which it is capable. BMW confirmed that by de-restricting the car it would not invalidate the car’s warranty. Lee Connolly said, "In reality having a de-restricted car is all about customer talk, fashion and a ‘mine’s de-restricted’ attitude – it is an emotional thing to have it. If the car is being used for track days or motorsport that is a different issue but outside Germany where can you use a car at that speed?"
