So the M4 just went live on GT6 for free, with a seasonal challenge on the 'ring GP track.
If that's how the car will handle in real life, then it's going to be fun as hell to hoon, but it's gonna suck on the track without suspension mods or better tires. Getting out of the corner in 1,2, or 3rd gear in full throttle pretty much induces some wild massive drifts. They're easy to catch, but reeling control is gonna add seconds especially if you're doing time trial. The worst thing about it is the turning radius, combine that with some understeer off throttle, it feels like you're driving an SUV. And as above, putting some gas on it will cause it to oversteer so it's definitely a handful of a car.
I am driving with a DS3 though so that might explain why I'm having a little trouble driving it.
Oh btw, it's a standard/premium car. Premium looks good like other premium cars from the outside, but the interior is all black like a standard car.
