While this thread is getting spicy Id like to join in on the fun and point out that you are a clueless old head and hypocrite.
In the other 6th gen threads you says reliability and a quiet drive are the most important features of a car. The 4.0 is both. Why criticize the 2023 drivetrain?
I test drove the 4.0 three times. I certainly agree that it is reliable. I don't agree that it is quiet. It doesn't have much torque at low RPM. You have to push it to high RPM to get power out of the 4.0 and at high RPM the 4.0 gets noisy and unpleasant, in my opinion. The 5th gen 4Runner gets terrible fuel economy for its size. It's a midsize SUV that gets worse fuel economy than full-size pickups. The transmission desperately needs more gears.
Does the 4.0 get better fuel economy than the 4.7 in my old 4Runner? It sure does. But, in my opinion, it is less pleasant to drive. YMMV.
I haven't driven the new drivetrain. I hope it will have better noise, vibration, and harshness than the 4.0, but I don't know whether that will be the case.
My experience with turbo four cylinders is limited to my wife's 2020 C300. Her previous C300 had a lovely V6 with great NVH and I was skeptical about the turbo four in her new C300. But you know what? That turbo four is a better engine than the V6. It has more low-end torque than the V6. It really scoots, even with low RPMs and moderate throttle. I don't think I've ever needed full throttle and high RPMs. It is quieter at low RPM. And it gets better fuel economy as well.
Will Toyota's 2.4l turbo four have similar NVH to the C300 turbo four? I don't know. The Mercedes four cylinder is a 2.0l, and smaller four cyclinder engines tend to have better NVH than larger ones, so time will tell. The 2.4l turbo four certainly has more horsepower and torque than the 4.0, and these come in at lower RPM.
As for reliability, again, time will tell. I trust Toyota far more than I trust Mercedes to get a turbocharged engine right.
Yes, I drive a 200 Series that gets abysmal fuel economy. I will be replacing it (hopefully soon), not due to its fuel economy, but rather due to frame rust. I'm realistic about its pros (lots of power, good NVH) and cons (horiffically bad fuel economy).
I think we should also be realistic about the pros and cons of the 4.0. The pros? It is reliable. The cons? It has bad NVH, little torque at low RPMs, modest horsepower, and bad fuel economy.
