Modern gear ratios
Why are the intermediate gear ratios in modern cars set so high?
Many cars with 6 speed gear boxes have the same peak speed in 4th, 5th, and 6th. Why not set 3rd, and 4th a little lower to aid overtaking from 30-50 and 50-70 mph.
My Mondeo ST can reach 90mph in 3rd, this impares acceleration between 50-70 mph when you need maximum punch. If 3rd peaked at 75-80mph the car would be much better.

For economy on the EC cycle so they can get a lower CO2 and thus lower tax rating.

I have a 2018 MB E-Class, it’s done 33,000 miles. The dealer tells me it needs an automatic gearbox service this year - £375 + VAT. Is it strictly necessary, and is that a reasonable price?
I am thinking of buying a used Citroen C1 auto but have read the ETG gearbox is best avoided.
Do you agree? Do you know why?
