For those who wish to combine looks with a bit more oomph, Hamann Motorsports offers a new ECU unit for the 630i, 650i and the diesel 635d that raises output by 21 hp. Moreover, customers can opt for the abolition of the electronic speed limiter which enables the 650i to boost its top speed from 250 to 270 km/h (168 mph).
And if that isn’t enough, you can also add a sport exhaust system, 20 or 21-inch alloys in various designs along with a series of interior accessories that include a 3-spoke sport steering wheel with an air-bag, a black instrumental dial with a scale up to 300 km/h as well as matching pedals, leg rests and hand brake handles made of aluminium.
