When I did tests on GSF and M4... GSF's gas tank was almost empty and M4's was 80% full.

So, the difference should be 15.8*0.8(M4's gas tank) - 2(GSF's gas tank) = 10.64 gallon.

The different in KG is 10.64 * 2.84 = 30.2176kg. (M4 had about 30kg more gas in the tank)

However, Q60's gas tank size is 20 gallons which is bigger than M4's...

So the difference should be 15.8*0.8 - 20*0.7 = -1.36 gallon. Actually Q60 had a little more gas in the tank...

Even though GSF's long 1st and 2nd gears and smaller rear tires, with about 30kg less gas it still could catch up with M4 at around 40mph and past it around 60mph...

------------ GSF ----------- M4
0-10 ----- 0.85 ------------ 0.78
10-20 --- 0.75 ------------ 0.66
20-30 --- 0.68 ------------ 0.85
30-40 --- 0.77 ------------ 0.97
40-50 --- 0.92 ------------ 0.78
50-60 --- 0.96 ------------ 0.97
Max G -- 0.69 ----------- 0.70

Even with much shorter 1st and 2nd gears and more sticky tires... Not sure why M4 did not perform well for 0-60mph tests...(It's just about as quick as those 300hp Nissans)

But, I do believe M4 should perform well in 100-200km/h or even higher...

Maybe those German cars are designed for Autobahn... But, we don't have Autobahn in Taiwan and USA. So, that kind of design is not very useful except you do illegal speeding on PUBLIC ROADS!!!

I think that's why this old ISF did so well on this short tracks (200m)...

These M cars are good but definitely not that good!!!

Unfortunately, many dumb people believe those nonsense numbers from car testers... Some of them said that M4 competition could do 0-60 in 3.8 seconds (vs 5.5 seconds for my son's G35S) So, those dumb people think they could become invincible when driving them!!!

One time a stupid M4 driver almost collided with my son's G35S on a very narrow mountain road 3 or 4 years ago . Not sure why that driver did such as an idiot thing???(Probably believed those stupid reviews) I had to do an emergency stop to avoid that accident!!! 拇指向下

The 1st and 2nd gears from GSF are much longer than M4's...

In my opinion, this difference is not a bad idea at all... Actually it's very good for at least 95% of the drivers on the roads who don't have racing skills. Both GSF and M4 have around 450 or above HP. So, the tire grip could be a problem at the 1st and 2nd gears. The longer gear ratios could help power delivery more effectively, safely and smoothly at lower speed especially when turning or on wet.

Of course, if you put AWD on these cars like GT-R, the grip would not be a problem any more!!!

It becomes even better... My GSF is also equipped with rear torque-vectoring differential... So, GSF should provide much better power delivery at low speed(high torque) turns even without AWD!!!

In my opinion, AWD will not improve handling or tire grips a lot even with torque-vectoring type AWD...

It just makes power delivery more effectively and smoothly... Based my experiences on torque-vectoring differential from my GSF, torque vectoring only helps the handling a little bit but not much!!!

My experiences are based on some daily spirited drives, not on racetracks... So the results could be different on tracks!!!

This guy bought a used M5(F10) in 2018 and drove it for about 20K kms. Guess what... In 2020 he had to replace the whole engine without any human errors!!! 嚇到吃手手

嚇到吃手手

And, that's also why he sold his M5...

In my opinion, AWDs including those with very advanced torque-vectoring will NOT increase grip-levels on your cars... They just make the power delivery more effectively and smoothly and reduce understeering or oversteering when acceleration.

They may improve the handling but not much...

To increase the grip-levels, you need more sticky tires...

Another accident...

I think this BMW driver tried to approve SOMETHING...

I think he/she didn't need to approve. Your car is already very good and better than the most of the cars on the roads... However, there are still some talented drivers around... They also could put very sticky tires on their cars to have more grips than your fancy BMW...

In my opinion, actually what this dumb driver tried to approve is "Yes. I'm very STUPID!!!" 笑到噴淚
