I Honestly have to say people are pretty surprised when they pull up next to you.and they think for a minute.oh that Dart can't beat me. Are they suprised when all they see is your back taillights. And they can't catch you. The 2.4 four cylinder Does it's job. I'm pretty hard on it. Who has topped there Dart At?? I'm just going to say well over 130 mph. I'm not sure what the 1.4 or 2.0 turbos do. Thanks Dart Owners.
