They increased redline and the tq comes on sooner. As long as power holds to redline should be just as fun. Hopefully the 2.4L will sound better

It had more torque of course, but torque like an agricultural vehicle, not a sports car. |

From quickly looking up the 2 on reviews, the 10th gen was about a second slower to 60 than the 9th gen. No wonder it feels slower. The 2.4 has more torque down low but when you're wringing it out that doesn't matter if you still make the same power up top, and weigh 300lbs more. I'm sure it feels quicker around town accelerating in the lower rev range, but that's probably it.

It made power, it made sounds...it was...an engine. The 2ZZ on the otherhand....sounded like a motorbike at high revs and wailed like a banshee when it engaged lift...and Lift gave it a turbo-like kick in the butt. VETAK KICKED IN YO!!!! |

I wasn't making a direct comparison to the 2.4L out of the 10G XRS, just noting that the two BRZ generations have followed a similar engine pattern. The FA20 and the FA20DIT landing in the BRZ and then quickly the WRX means they saw more performance oriented design aspects like the high redline and in Toyota's case the focus on extracting all the NA performance regulations and engineering margin would allow them. Then the next generation we get an NA version of a turbo SUV engine with a more hands-off approach from Toyota. I'm worried it's going to drive like one. With the announcement their model is getting pushed back I'm definitely not buying first year. |

It makes peak power at 7000rpm. That is where it wants to be. And it makes 23hp more than the current gen at that rpm. We get another 100rpm before the rev limiter, so it will stay (slightly) further up in the powerband after upshifting. I don't see any downsides. Here's what relative rear wheel hp and torque should look like:

Another good indicator is that the stroke (86mm) was unchanged, and only the bore enlarged (86mm>92mm). Typically engines with larger bore/stroke ratios like revving more than ones with lower bore/stroke ratios. |

Especially when that extra space is used for larger valves. Most of the time when getting a displacement bump OEMs go with a longer stroke which negatively impacts high revs. Fortunately they didn’t go that route. There’s no reason this new engine should be less rev happy. |

The only issue I can see with this engine is the higher compression ratio (13.5 vs. 12.5), which it could affect performance more with lower quality fuel. Such compression ratios were used in the past mainly in racing applications, where someone had access to racing quality fuel. It looks they went into that direction to extract the best possible performance figures under this displacement level and latest emission regulations. E85 and Flex fuel kits could be a solution for those having access to such type of fuel. And of course the worst option would be to supercharge such a high compression engine ...

I doubt they'd lower the recommended octane, but that doesn't mean the car won't run sorta okay on lower grade fuel. The ECU is smart enough to pull enough timing to make it work.

The current engine runs sorta OK on 87. The new one is a substantial increase and would probably be pushing even the ECU to it's limits as far as correction goes. In other words it would probably run like crap. Even Joe and Jill Generalpublic would notice the difference.

They likely have the same basic requirements regarding how well it runs on 87 for the new model as for the current one. Could be improvements to combustion chamber design, fueling, and spark control make it possible to have the same "driveability" with lower octane fuel with the increased compression ratio.
long/short: I wouldn't worry about it... Especially since we're all gonna use 91 octane minimum anyway! |
