We took this 2007 Mercedes-Benz E550 to the test track on July 13. It was a Thursday, and it began like any other day. Just as we always do, we arrived around 8 a.m., set up the ol' radar gun and began to make passes down California Speedway's new drag strip. No big deal, just another day earning the bacon. Then it happened. The Benz reared back and blitzed the quarter-mile in 13.5 seconds. Holy Stephen Hawking Batman, 13 seconds on Thursday the 13th. Kinda makes your skin crawl, doesn't it? OK, so maybe it's not that weird. Alright, it's not weird at all. But a 13.5-second quarter-mile is freaky quick for a car in the luxury midsize segment. Just a few years ago, an E55 AMG accelerated at that rate and was one of the quickest sedans in the world. To use a technical term, the 2007 E550 hauls ass.
