Just did a quick check on Mercedes' German website, tried to find some models that are still offered with manuals, and got this: B160d - faster with automatic B180 - faster with automatic B200 - faster with automatic C180 - slower with automatic C200 - faster with automatic C220d - faster with automatic CLA180d - same CLA180 - faster with automatic CLA200 - faster with automatic E200 - faster with automatic I'm sorry, but you are wrong for at least one of the manufacturers you listed. I only found one Mercedes model where they reported a slower 0-100km/h time for the version with the automatic transmission. I'm pretty sure the numbers for the other manufacturers are similar. Automatic transmissions have simply surpassed manuals. Yay, technology!
