That's correct. Since the Bathurst update (or probably ealier), for special events the more you upgrade, the weaker the bot gets. If you are an elite player who race without any assist, then you can pass the challenges with PR way under the recommended PR. Most people could pass the challenges at 1 or 2 PR below the recommended PR.

For this update, it's worse. Many people complained that the challenges were very difficult. I think it's because the targets are fixed (reach xxx top speed, or xxx average speed, or finish under xxx seconds). I actually upgraded Furai to 4344333 to finish the event (I just didn't have the time/patience for multiple retries) and even with that it's not easy.

I missed Gauntlet 1-5 and didn't pass 6. For Gauntlet 7-11, the boss gets weaker as you upgrade more, but at later stages both boss and non-boss challenges would get incredibly challenging even if you upgrade. For Gauntlet 12, you just had to upgrade one car and complete it in one run.
