And I disagree as well (and that's okay). Before I go on, we do know you gave examples of two cars that have their engine size limited by the rules and regulations of the governing racing body? They have to choose engines that small. A comparison like that only works when you are comparing apples to apples. I wouldn't say an open wheel racecar can be compared to a full-size, commuter car with airbags, radio, heated seat and extra features etc.
In addition, let's look at it from an engineering point of view. This motor is going to need 20+ PSI to reach these power numbers. Any car that relies on boost to make power generally feels sluggish when off-boost. To counter this, OEM's will fit an extremely small turbocharger to minimize lag. This means that tuning past OEM specs will provide very little gains. That's not taking into account the extremely high cylinder pressures that are already occurring from that much boost in a stock engine. So this issue is, for people like me who tune their cars past a certain point, is that it will likely prove to be an ineffective stock turbo platform providing minimal gains for the mods that "90%" of people do. Furthermore, the 1.5L 3 cylinder will fail to flow enough air to spool a larger turbo reliably, which limits tuning past OEM turbo stuff. So while it may be appealing to you, for people like me, the news is disappointing.
