I test drove a new 2013 300C V8 with only 15 miles on it. It's a very nice car but it seemed sluggish. I didn't want to beat up the brand new car but passing under some lights I did slowly push the gas to the floor. The response was unimpressive. I've driven other 300's and Chargers so I expected more. Is something off with this car? I've read rumors that Chrysler has disabled some performance features prior to the first xx number of miles.
