Without good transmissions, we only could explore 50% fun of these combustion engines.
That's why I kept pursuing more powerful engines...
(Actually the problem is transmission, not engine)

That's because AT could slips on torque converter. Those slips or power loss could be transferred into HEAT on ATF!!!
However, modern AT will reduce slips by aggressive lockups. So heat or power loss will not be a problem any more...

Actually around 120km/h on highway I only had 2 gears available in my previous Nissan which were 4th and 5th gears.
In GSF I have 5 gears available which are from 4th to 8th gears. With those additional gears, my GSF can be as tame as a sheep and also as brutal as a beast...
(VERY VERY DIFFERENT... And all depend on your GEARING decision!!!)

Nowadays modern turbo cars more focus on low rpm performance... It's very good for average drivers but not so fun for car enthusiasts as modern turbo cars are only OK at high rpm...
Again, NO CAR is perfect...

1. The rear PSS tires are already 5 years old. I have to replace them next year because of their ages. However, they are still at least 40% treads left.(even after 50K kms!!!) So...
2. My GSF is still in CPO warranty (not factory warranty) So, I need to drive more mileages for my GSF to let any potential problems show up like the problematic fuel tank cap.
3. Next year I will buy a brand new 400Z or a used Q60 (or something similar) to replace my wife's old M35X... So, I will have less time in driving my GSF as I will spend some time in driving the new Nissan next year...
4. To keep having fun with my Ohlins DFV (16/12K) suspension...

This is another shortcoming on driving these fast performance cars... (I'm still waiting for ISF with new twin turbo V8 to replace my current GSF 5 or more years later)
5 years is not a short period but I'm really not sure if Lexus can make it as they are VERY SLOW usually...
That's why I always love to buy a fun car from Toyota, Nissan, etc once they make one... (It's not EASY for them!!! And also for us because of the long wait...
)

Guess what... I think I finally know why my GSF is so expensive!!!
The sport seats in my GSF are much firmer but after the 350km trip was finished I did strangely feel more comfortable in my GSF even with very stiff Ohlins DFV suspension.
The other thing is the steering. Actually Sienna's steering was good, accurate and weighted. However, the steering in my GSF is better and also much lighter. So, my arms felt sore with Sienna (and my wife's 2010 M35X) but did NOT with my GSF after a long trip.
Of course, my GSF is much more joyful to drive but 2017 Sienna is not a slow car at all which comes with 300hp 3.5 V6 and 8 speed auto. (0-96km/h in 7 second)
The below is 2016 model which only has 270hp and 6 speed auto.

Believe it or not... I drove it to about 150km/h on highways at maximum. However, when I found the maximum speed on its speed meter was only 175km/h, I suddenly realized that I really should not had driven it that fast!!! So, I kept its speed under 145km/h...
PS: These days California drivers are more aggressive. 130km/h on highways is normal and 145km/h is not unusual...
(Of course, I just followed those aggressive drivers and kept a very good distance from them for better safety)
