The E 55 was the fastest production sedan available until Mercedes-Benz released the S65 AMG. However, Car and Driver criticized the brakes on the E 55, chastising them for being difficult to modulate, and said that the car as a whole felt 'aloof'. Car and Driver also tested an E 55 AMG Wagon, which weighs more than the sedan. They found that it accelerated from in 4.1 seconds and in 9.7 seconds. The E 55 was a sales success, being the best selling AMG until the release of the C 63 AMG. 2006–2009 (mid-generational refresh) The W211 was updated in 2006 for the 2007 model year. There was new standard and optional equipment, which enabled the W211 to hold its own against its competitors.
