MT or Tiptro?

When my husband bought his 911 (964C2)"Do I go with the manual transmission or the Tiptronic?"In the end, I chose Tiptronic.

At first, they were considering a manual transmission, but there were very few MTs in good condition, and even if there were, they were either outrageously expensive or had been modified in some way. Her husband wanted to keep the car in completely original condition, so he found a few Tiptronic cars with high quality, nearly complete maintenance records and provenance, and the price was acceptable.

And because the majority of the world's many air-cooled articles and blogs are about MT cars.It would be interesting if I dared to buy a Tiptronic and disseminate information about it."And as for Porsche's MT, he seems to have chosen Tiptronic this time because he can taste it in the Boxster GTS.

So, the other day my husband compiled a report on his impressions of Tiptronic at this point in time, which I would like to share with you today.

Here are my husband's impressions

The most important concerns of people considering buying a 964 or 993 are"Do I go with the manual transmission or the Tiptronic?"I think. I was also very much confused, but I decided to go with Tiptronic for this 964.
According to the information at hand, the car's Tiptronic was jointly developed by three companies: ZF for the gearbox, Bosch for the electronics, and Porsche.It has five modes and automatically switches between modes based on the accelerator pedal position and other factors.It also seems to be designed to take into account information such as lateral G-force. It also seems to have a mechanism that takes into account information such as lateral G-force and prevents unnecessary upshifting on curves.

(1) Gear shift shock

In the city, etc.When riding normally in D range, there is extremely little gearshift shock.The AT starts in 2nd gear when in D range, but there is no shock at all, and it is hard to believe that this is an AT from almost 30 years ago. Speaking of ATs of cars I knew back then(I only know about domestic cars)I had an image of a big gearshift shock, shaking back and forth every time I shifted gears.Tiptronic is extremely goodIt is.

Incidentally, if you dare to start the car in first gear, and if you mean to ease off the accelerator just before going into second gear, you will feel some shock, but otherwise, the car will connect smoothly.
And when I say shock, I don't mean it's that unpleasant.'I wonder if there would be this much of a shock if a human did well in MT.'This is only to the extent that one would think that the engine is not working properly. If you ride carefully, you will notice a slight drop in engine speed when the lock-up is engaged and a small vibration when it is disengaged, but this is only noticeable when the accelerator pedal is opened and closed at the wrong time and you are not aware of it.

The maintenance record of this car shows that the AT fluid has been changed twice in the past, which may be attributed to its relatively good maintenance condition, but even leaving that aside, I think it is a good AT.

(2) Manual shift

I shifted the shift lever to the right and tried manual shifting; the rpm range where the lock-up occurs is a little lower than in D mode, and the connection feels more direct. Accelerating in 2nd gear with a little more energy, the lock-up is connected more directly than in D range at around 1800-2000 rpm, so the engine speed drops for a moment and I feel as if I have shifted gears. The engine speed drops for a moment, and it feels as if it has changed gears. The shifting speed may not be fast, but it is not slow either.

While it certainly cannot match the speed of modern ATs and PDKs, it is never like the old ATs that would shift gears after a two-tempo delay.

For example, when you are driving in 3rd gear at a reasonable speed on an ordinary road and a corner is approaching, you step on the brake just before the corner and manually shift to 2nd gear. With a slow-shifting AT, you may have already entered a curve by the time the gearshift starts, but this is not the case with Tiptronic.

If we could time it accurately, we couldIt's almost the same as the average person operating and shifting gears on a manual transmission."orTiptronic is faster, depending on timing."I think.
I have often heard that "Tiptro is slow shifting" or "MT is the only way to go," but after driving it, my impression is that it is not that much to say. I think that a poor MT operation would be slower in some cases, as well as having shifting shocks.

(3) Acceleration and speed

Next, how about from the viewpoint of acceleration and speed? According to catalog values0 to 100 km/h in 5.7 seconds for a manual transmission vehicle, compared to 6.6 seconds for the Tiptronic.and about 1 second slower. However, theReversed in realistic, frequently used intermediate acceleration of 100 to 120 km/h, etc.The first time the MT was used, it was the first time it was used in a car. According to test data from CG magazine at the time, "The MT is a 3-speed(Fastest gear in this speed range)The Tiptronic takes 1.9 seconds compared to 2.2 seconds for the Tiptronic.

In fact, I do not feel an itch when accelerating in town or at high speeds.This is because the AT's lock-up starts at around 1100 to 1200 rpm and directly connects at around 2000 rpm, so the AT maintains almost direct connection during driving. Thanks to this, the driver can accelerate as expected without feeling any slippage or dry running that is common in the old torque converter ATs.

MT or Tiptronic?

Now, let's look at the finalWhich is more fun, MT or Tiptronic?"If you ask me, the answer is obvious. I think so because I usually drive a Boxster MT.

In the case of Tiptro, second gear covers up to about 130 km/h, and third gear to about 195 km/h. While this is good for enjoying the engine's extended acceleration, the MT's second and third gears are capable of approximately 110 km/h and 160 km/h, respectively, so the MT is more capable of revving the engine under Japanese road conditions.Looking at gear ratios alone, MT will often be 'fun'.

However, this is only in comparative terms.This is not to say that Tiptronic is not fun.This is a painful way to drive on a mountain road or on an open road with manual control, even if you are flowing in D range. And if you want to overtake quickly and at high speed, you can just step on the gas pedal without thinking, or you can downshift yourself.

Personally, I find it especially pleasant to drive along an open country road in 3rd gear. The ratio of the accelerator pedal to the engine is in direct proportion to the engine rpm, and the direct connection between the right foot and the engine is a pleasant sensation.The engine neither turns too much nor too little, and the air-cooled sound of the car's background music makes you want to drive as far as you can along the gentle curves and long, straight stretches.

If anyone is on the fence about whether to go Tiptronic or MT.

If you want to drive hard on circuits or mountain passes, I would recommend the MT, but if your main use is for daily use or long tours, the Tiptronic is perfectly fine.

Tiptronic cars are also cheaper, with a slightly larger number of units, and many of them are in relatively good condition.
