I'd be interested in the thoughts and theories from other board members regarding the tested quarter mile times for the E55. In some of the initial automotive press testing (MY'99), 13.4/13.5 seconds at 105-107mph seemed consistent. In later comparison tests (MY'00)with, for example, the XJR, the E55 turned in 13.9 seconds at 103mph. Up to a 1/2 second disparity is generally regarded as significant for the 1/4 mile. Any theories on the difference? Could it be the '99 model year v. the 2000MY? Thanks.
