But in any event, it may very well be the case that the newer cars have some ECU programming that cut power on launches. In the real world, they aren't "substantially slower." In fact a lot of people who test drive them feel they are much quicker. But really, the STI has been pretty consistent in performance from 2004 to present day. A few tenths in the 1/4 mile doesn't change that. While you guys are about a few tenths, the Mustang GT went from low 14s to mid 12s between 2004 and 2020. |

You are not going to get close to any of those numbers anyway. The STI has always been about feel grip and handling, not 0-60 numbers which can only be achieved through serious mechanical abuse. When the camry's of the world starting having 300 HP, bragging about STI acceleration should have stopped. |

Look at you, just wanting to argue. Your points are invalid!

I'd argue the STI has been about reliability. Residual value reflects how awesome the reliability really is.

Speculation about why the next gen STI was delayed till 2022 at the earliest.
So after doing a bit of research I wonder if the slower times of the MY18+ cars come down to the wheel/tire combos?
A 2015 STI Limited with the BBS wheels has a combined wheel and tire weight of 47.1 lbs. A 2015 STI base has a combined wheel and tire weight of 49.25 lbs. A 2018+ STI has a combined wheel and tire weight of 54.4 lbs. So the total rotational weight difference of the wheel/tire combo between a 2015 STI Limited and a 2018 STI Limited is 29.2. Comparing base to base the difference is 20.6 lbs. So either way you slice it you’re looking at either a 20 or 30 lb. difference in the rotational weight of the wheel/tire combos. This will definitely affect acceleration and is most likely the cause. Last edited by Lminette; 08-13-2020 at 04:51 PM. |

The DCCD AWD system was also updated to some degree as well. At the end of the day the cars are not appreciably slower and as others have explained, you're not/shouldn't be red lining and clutch dumping your car each time you launch.

Front rotor size went from 325mm to 340mm for 2018. Rear size went from 318mm to 328mm; the rear rotor has now a larger diameter than the front 2004~2017 rotors. But, I seem to remember that these weight differences (wheel+tire+brake) were already brought up in past discussions and the consensus seemed to be that all that extra weight do not completely explain why the 2018 is slower to 60. No doubt, the extra weight doesn't help though; but, IMO, the 2018 STI brake upgrade is most welcome. |

Good call on the brakes! Spaced on that! This is however rotational weight not just weight. It's the worst kind of weight in terms of robbing you of power so my money is still on this being the primary reason.

I also roughly calculated the inertia of the 19" and 18" wheels and it wasn't that big of a percentage change. You can search for my post on here if you're interested - assuming derphawk didn't get the thread caved. |

I read an article today that said the release order of the next gen STI and WRX was leaked and the STI is going to be released first in 2022, and then the WRX later at the end of 2022. Releasing the STI first makes sense since it is the flagship performance car from subaru and it will get people into the dealerships.

You have that backwards, WRX in late 21 and STI in 22

Regarding Acceleration Differences and using CarAndDriver as the benchmark.
2015 STI Limited - 3390 LBS 0-60 - 4.6 5-60 - 6.3 0-100 - 12.0 0-130 - 26.1 2018 STI w/Recaro Pckg - 3451 LBS 0-60 - 5.3 5-60 - 7.0 0 - 100 - 13.0 0 - 130 - 25.7 To separate the impact of the launch from (c-diff change) from tuning (pulling timing in 3rd or 4th gear) I wanted to look at the acceleration differences between 0 to 60 and 0 to 130. 2015 - 25.7 - 4.6 = 21.1 2018 - 26.1 - 5.3 = 20.8 So essentially the same (within 2%) Now this is not an controlled test, and these are the adjusted numbers, not the raw numbers. For what it's worth I don't think the regular 2018 STIs are any slower than the 2015s; other than the launch. The RA model does appear to be moderately slower, which may be attributed to the tuning change (maybe for engine preservation). The differential of its 0 to 60 time and it's 0 to 130 time is 23 seconds, or about 11% slower than the base 2018 STI. These differences slightly are less significant when looking at the 60 to 100 times (~8-9%). There's not enough tests of 2019's or 2020's to confirm they've improved the tuning. FWIW, I cant tell the difference from the 2015 and 2017 models I've driven as compared to my 2019. With respect to my 2019, I do notice more variability in performance dependent on weather conditions than other (non-subaru) cars I've owned in the past. |

no I dont. This was new info that was just leaked. The STI is first in 2022 for SALE and then the wrx for SALE later in 2022. When they actually go on SALE is the key here...not necessarily when they are "released".

Sorry, the leaked image shows WRX first. WRX has more sales. Doesn't make sense to push out the new STI first.

Can you imagine?
Subaru: We are very proud to introduce the BRAND NEW 2022 Subaru WRX STi. We have heard your voices loud and clear, which is why we have brought back the STi in your choice of either sedan or hatchback. Also Subaru: Also, it has an EJ25. Have fun! |

And sure they could do that with a new 2.4 as well, but why bother when the FA is going to knocking on the door 10 years of use in the WRX platform in 2022 , its not going to be a "new" engine if its put in the STI at that point....and electric drive is going to knock the FA's out pretty quick within a few years of being in the new STI...its just going to be aging fast...and relatively faster than even the EJ did as during all of the EJ years, electric drive was nowhere NEAR as prolific as it is now. So why not just keep the EJ for 2-3 more years? They have Ironically never even scratched the surface of its capabilites when modded and could if they wanted to. This is a very interesting time for subaru, hopefully everyone can appreciate it. |
