Motor Trend - How the 2018 Buick Regal GS Stacks up Against the Kia Stinger GT

I think these are all good posts here and bring out several important points that are not always given in testing.
1) RWD vs. RWD w/ LSD (Limited Slip Differential), vs. AWD
2) Launch Control used or not (the C&D numbers on their first report were without)
3) 19" vs. 18" tires
4) What tires (make and model - there may be more than one supplier of tires for the car depending on the market)
5) And as others have pointed out, ambient temperature, surface grip and temperature, etc.

As I've mentioned before, I would expect some times to be better than 4.7 sec. 0-60mph because in order to advertise that time, it would have to apply to all versions and combinations or Kia would have to issue a disclaimer for drivetrain and/or tire variations as they did with the top speed. I don't think Kia's lawyers would allow them to advertise a result that all 3.3TT's couldn't reach.

I agree these factors should all make minor differences and we do need more direct comparisons tests using same equipment.
However the 4.7 time from KIA did have a disclaimer that it’s specifically from the GT RWD w/19” wheels like Xot1 said above. They picked that version to show the fastest times from their own model tests. Not all the versions are the same times as we see in the real world tests. For whatever reason the RWD w/19” seems to be the quickest amongst all testing available at the moment. So it’s great to see people running 4.52 from the AWD versions which is 0.1-.06 faster that previous confirmed tests.

Thank you @xot1 I’ve been wondering about OEM wheel weights! Well done!
