Glad I finally saw the link. I was going to say what a crappy article as the text said nothing about the suspension and adjustments. Obviously after all the praise I knew I better have another look.
The authors got it completely wrong though about the M3 differential it is not an electronic diff, it is fully mechanical. It is the GKN Viscodrive system.
The praise for the over achieving car also leaves out one very key ingredient - the driver!
