Does anyone know if it's normal to have some hesitation from a complete stop? For example, if I did a 0-60 run, as soon as I push down on the accelerator pedal there will be a delay of close to 1 second and then it'll take off as normal. It doesn't seem to struggle to take off, it just seems to wait a short moment before it actually goes as if I wasn't pressing down on the gas.

Same here, Sport mode with paddle shifters seems a bit better if you are looking for a quicker start.

It's normal. The ECU also limits torque in 1st gear. In Sport mode, aside from more aggressive shift and throttle mapping, and additional clutch slip, it also raises the idle RPM by around 100-200.


My former '17 Elantra sedan had the same kind of throttle mapping, in Normal mode.

I doubt it's actually a full second but yes it feels like a lifetime. I've found this to be typical of most/all automatics/DCTs. Seems to be worse with turbo cars.

DCT is different. It needs that short moment to engage/slip the clutch, depending on throttle request. Traditional automatic still spins with the unlocked toque converter, when stopped. Turbo cars also have a moment of turbo lag, to spin up, of course.

I only really noticed it after I raced my cousins 2012 Lexus IS250 lol. He got me from a dead stop because of that lag but eventually I caught up. Still, it sucks that my car is technically half a second slower than it normally would be due to that delay.

*shrug* 0-60 is a meaningless single metric in most circumstances. Grip is compromised on a FWD car, and the Hankooks on DCT cars are.... "OK", at best. Unless you're on warm, grippy, near-perfect pavement, a full-throttle start on these cars in 1st gear will ALWAYS result in lighting 'em up, despite on-throttle torque management. Your car isn't a half second slower because of bad programming, it's a half second slower due to inadequate driver skill and knowledge of the vehicle. Just please don't full-throttle through a cloverleaf freeway on-ramp, or you'll wash out the inside tire and merrily understeer into the guardrail.



The IS is RWD, so he's always putting that stonkin' NA 205HP/184ft-lb down on the drive wheels.



You'll always eventually catch up, because you have a nice flat torque turbo curve paired to a shorter-ratio transmission, and are a few hundred pounds lighter.
