Ferdie, I calculated the gear ratios and tyre size and then was able to make such an assumption. The SL55 at Nardo had 617bhp or 626PS. It was carrying the prototype SLR engine in it. The gearing of the SL55 only allows it to do 202mph. Also the E55 has a more smaller frontal area, longer gearing (rear axle ratio of 2.65 vs 2.82 of SL55) and has a better drag coefficient. From this, and due to the powerful engine, which IS rated at 500bhp The E55 can do 206-208mph. I can show you the website I used if you like.

Oh and another thing, RC can completely back up my theory, just ask him


agree too !!
