I just got the Veloster N yesterday and noticed it had a slight hesitation when the gas is pressed. The only way I can describe it, is it is like a carbureted car back in the day, that would put too much gas in initially and slightly flood before leveling out (sorry, I am older). It very well could just be normal but I wanted to see if any one else experienced that. It could be something with the exhaust and the way it sounds too. Just wanted to make sure it wasn't something wrong with the car. It was doing it when I bought it and already had over 60 miles on it at the dealership. Thanks!

Are you in Normal or Sport mode when you notice this? This shouldn't be an issue in "N" mode, but Sport has a somewhat wonky throttle response curve that makes shifting quickly a pain. As this car is "throttle-by-wire" the amount the throttle blade has to be open relative to the gas pedal doesn't have to be the same. Having said that, the N mode (and N Custom, as I use Sport+) feels rather linear to me.

Give it time to break in, you just got the car. The slight delay is with the turbo spooling up. If you don't like it get a power pedal. It will speed up the throttle response lag.

The amount of TB butterfly response is about 80% of what is being applied from the accelerator. The same with a lot of motorcycles. The ECU needs to be adjust with the actual throttle butterfly position but this requires a specific tune. So, the only thing you can really do is; add a power pedal to speed up the response.

He came from a 2020 WRX to this. He's familiar with modern, turbocharged vehicles. And yes, there's a stupid delay thanks to odd throttle input mapping that was horrible in my 2019 R-Spec, and my 2020 N PP can act a lot like it if I use Sport mode. I didn't notice it for the first week because, well, why bother with Sport mode? I only tried it just to see if it behaves similarly, and it did (just not as bad).

Thanks for all the responses. Seems to happen in all modes. It is just right when you give it a little gas, it kind of lags as the clutch is being released at first. Hard to explain. Nearly feels like it wants to go dead, then will rev up just fine. I will keep an eye on it but was just curious. I know the car sat on the dealer lot for a while for sure. Love the car though. Can’t get over how you can change the whole feel of the car with a button! So cool!

When I put in my GFB BOV which is adjustable, the soft spot/lag went away.

Best regards,

I’m noticing the same thing with mine. Slight hesitation upon throttle application. my lasttwo daily drivers have had been V8s. One naturally aspirated 5.6 and another with a roots supercharged 4.6... both had immediate and powerful responses to throttle inputs. This is my first turbo engine and maybe it’s just a different power delivery... but I’m hoping a JB4 or Pedal Commander will help fix it.
