Porsche 911 (991 late model) Sport exhaust & sports mode fuel efficiency comparison 2

Comparison of fuel consumption in various modes with Porsche 911

In the late 991 model of my car Porsche 911 Carrera (I'm Mr. Carrera),I had a sports exhaust retrofittedSo after that"Only when the sports exhaust (hereinafter referred to as" Spoeki ") is turned on"When,"State with Spoeki ON + Sports Mode ON"InComparing fuel efficiencyhad.

There are 4 patterns to enjoy after installing Spoeki on the 911.

Porsche 911 with Spoeki has the following four modes that you can enjoy by controlling the buttons inside the car.

Of these, the last time we compared the fuel efficiency of sports mode ON and OFF in the state of (1) and (2) Spoeki ON.

What I was interested in here was ③ and ④ that I did not do last time. In other words, although the Spoeki was retrofitted, the fuel consumption is in the state where the sports mode is ON when the Spoeki is OFF, and in the completely normal state where both the Spoeki and the sports mode are OFF. (In the first place, I never run with Spoeki off ... (laughs), but I'm just interested!)

Finally, there was a day when I could run comfortably without using the air conditioner, so I immediately compared the fuel efficiency.

Porsche 911 has bad fuel economy when using the air conditioner ~

By the way, the fuel economy was really bad while using the air conditioner. I usually see the fuel consumption figures, but that doesn't mean I'm running with particular concern, but the numbers that show the fuel economy are usually "7-8km" even in the neighborhood. Even though I went there, the period of use of the air conditioner was always "4-5km" (laughs), so somehow I was catching it at the edge of my field of vision, such as "Hmm, I can't go up from 4-5km!".

When I was using the air conditioner comfortably, I couldn't stop idling when I was waiting for a traffic light, so it was interesting to see the fuel consumption figures drop steadily during that time. The numbers are really falling.

Fuel consumption measurement with sports exhaust off + sports mode on

Well, the story is off, but I immediately tried running on the same road as last time in the sports mode at Spoekioff, taking the same amount of time!

The switch in the car is in this state. The switch of Spoeki like the glasses mark is off, and the lights are on "SPORT" on the upper left and "A OFF" on the lower right. When the sport mode is set, the idling stop is automatically turned off, so this "A OFF" is automatically turned on. (It's complicated ... (laughs))

Well, here is the result.

Similar to the previous time, when I ran with "required time: about 28 minutes", "mileage: about 10.9 km", and "average speed: about 24 km" as indicators,Spoeki OFF + Sports mode ONThe fuel consumption in6.7km / L"was.

Oh ~ I think fuel economy is bad ~! I feel that the reason why fuel efficiency is poor is that "because it does not stop idling" is a major factor, rather than "because it is in sports mode" when it is set to sports mode.

By the way, when the sport mode is turned on, a really small "Sport" is displayed in the yellow circle. I hardly notice it (laughs)!

Fuel consumption measurement with sports exhaust off + sports mode off

By the way, at the end, I would run in the normal state of "I will never run in this state" and "All sports and sports modes are OFF". There is no light on the switch system!

Well, the result.

I aimed for about the same running time, distance, and speed, but this time I was addicted to strange traffic jams at the last few minutes of the measurement, so when I took the last photo of the numerical display The result is a little strange.

Actually, the fuel consumption was 11.3km before I got stuck in the traffic jam, so if I could drive normally for 28 minutes without traffic jam, and for another 2-3 minutes, I wondered if the fuel consumption of 11.3km was certain. that's why,Spoeki OFF + Sports mode OFF = All OFFThe result is "11.3kmI would like to say.

911 (991 late model) Sports exhaust Fuel consumption comparison result in 4 patterns running after retrofitting

The results for all patterns are as follows.

Fuel economy on general roads in Tokyo (normal street driving full of traffic lights) with a driving time of "about 28 minutes", a rough mileage of "about 10.9 km", and an average speed of "about 24 km" It is a comparison. * Although there are differences between going and returning, they all follow the same section of the exact same road. * No air conditioner is used.

Hmmm. on second thoughts"All OFFIs the best fuel economy. Absolutely. and"Sport mode ONIf that is the case, the fuel efficiency will be worse. Easy to understand!

However, as I wrote earlier, in sports mode, the idling stop is turned off, so when driving in the city, it stops at a traffic light, but it does not stop idling each time, and the fuel consumption value is steadily increasing while stopped. Can be seen going down, so "Idling stop turns offI think that is the number one factor that makes fuel economy worse.

My favorite mode combination is ...

And and. The state of my favorite mode is definitely "Only Spoeki is ONIt is in the state of "! This is the best for me.

I don't feel the need to switch to sports mode for running around the city normally, and I wonder if it's necessary to make a crunchy bubbling sound (laughs). After all, I like the state where only Spoeki is ON!

On the other hand, the first thing I thought "How about this?" Was not "all off" but "all off".Sport mode ON with Spoeki OFFWas it in the state of?

Perhaps because the Porsche is off, there is almost no bubbling sound even in sports mode, and on the contrary, because the car is working hard in sports mode, the engine sound sounds more cascading ... (← Other modes to the last) Compared to the pattern of, the story does not mean that Porsche's engine sound itself is bad). I felt that it was a sound that I couldn't say "this isn't it". It's completely my personal impression.

This time it was a result of driving in the city with many signal stops, but I think that it will change a lot if this is high speed again, so I will measure it someday ... (laugh)! !!

This time, it was only about 28 minutes each, but it was really hard to run at Spoekioff! !! After all, I don't think I can ride the Taycan (Porsche's electric car), which may be quiet, with the current mindset (laughs).

That's why I'm glad that I was able to compare the fuel efficiency of the four patterns I was interested in. This time, I tried to "run in the same way for all four patterns" as much as possible, and I did not dare to drive too ecologically, and on the contrary, I drove without stepping too much.

But. If you turn on Spoeki when you are running normally without measuring, you may unknowingly (consciously ...) step on it in search of a good sound, so actually Spoeki is turned on. Then, I think the reality is that fuel efficiency is worse (laughs). perhaps!

There were still two patterns to measure ...

* After this, my husband said, "With the BMW 650i, there is not much difference in fuel efficiency depending on whether idling stop or not, so Porsche is not the main cause of idling stop, but because it is in" sports mode ", there is a big difference in fuel efficiency. Isn't it out? Is pointed out.

Then, "Actually, there are two more patterns,

But isn't it? In terms of fuel consumption measurement. " Uuu. That's quite true. If you do this, you will somehow understand how much the idling stop is affecting.

it can not be helped! Next time, if I have a chance, I will measure it (laughs).
