Why is my 2016 Mustang so damn slow?!?

It’s an Ecoboost, first and foremost. I put in supreme gas, but, I could not pull away from a 2017-19 Kia Rio! So, I decided that it was just bad gas. Today, I couldn’t pass a 2006-08 Dodge Ram diesel (the kind with the wide ***, not too sure what they’re called). I’m sure if he didn’t brake I would have passed him eventually. But, it was taking seconds for me to catch up. Also, car websites where I can get advice and ask questions like these?

    Have you ever researched the absurd power and torque figures of a modern diesel pickup? Many of them make 400+hp and 800+++ lb-ft of torque, bone stock. (And many of the older ones are only a plug-in tuner and some very cheap mods away from making similarly absurd amounts of power/torque). Yes those trucks are big and heavy, but that's a LOT of torque and power. I wouldn't be surprised to see a dualy leave an ecoboost Mustang in the dust for a short stretch at lower speeds.

    As for the Rio, I don't know what to tell you there. Your car should be significantly faster than a Rio (a couple of seconds faster through a 1/4 mile if you're comparing documented performance figures), but that 2 second difference assumes the Mustang doesn't spin the tires and is being driven at wide open throttle and shifted at/near redline in every gear etc., - if the Mustang driver was short shifting and/or got a craptastic start/spun the tires off the line etc., while the Rio got a perfect launch and just held it to the floor the whole time, it could take the Mustang a while to reel the Rio in.

    Because you were a cheapskate and didn't get the V8.

    You didn't buy a car for speed. It's designed for economy. To improve performance you'd not only have to modify te motor, but the trans & rear end. If you want performance, trade it in.

    "It’s an Ecoboost," There you go.

    The Mustang is a very heavy car. The Ecoboost option simply doesn't cut it.

    You buy a Mustang and go for the "eco" option. Doh!

    You're wasting your money on "supreme" gas. READ the owner's manual that came with the car. It will tell you the proper fuel to use.

    I rather think it's you that's slow. The gas octane has no effect on performance except for some exotic sports cars. A good mechanic will diagnose the power deficit.

    Mustang: That's a Cortina right? You should have got the 2.3i engine.

    Well 600+ foot/pounds of torque on the truck explains a bit of it.
