The W108 and W109 series were produced from 1965 to 1972. While its replacement, the W116 was the first model called the S-Class, the W108 and W109 models occupied that spot in the model range. When drivers new to this range first experience these cars, they often comment how high the engines are revving at motorway speeds. This is not like the cars...
The R/C107 models had an extremely long production run – 18 years. There were a variety of different models and specification changes. This included the differential ratios that can have a big impact on the performance and economy of the vehicle. In compiling the table below, I have tried to research the various country specific variants. It is possible I have missed a few. ...
I changed the differential ratio of my E-Type about two years ago. My car was first delivered in the USA, so it came standard with 3.54 ratio. Most of the 4.2 cars were standard with 3.07. When the car was restored in the 90’s, it was converted to 3.07. However, the previous owner converted it back to 3.54. My conversion put...

Not only did they vary between models and years, but in some cases countries too. It is possible I have missed a few more country specific ratios. Please indicate in the comments below if I have. The data...
What the best differential ratio is for a straight six engined E-Type (Series 1 and Series 2) is one of those topics that generates plenty of opinions. So much so that my car has had two changes over its life. US delivered E-Type started life with a 3.54 ratio, which my car now has. This is the same ratio it had when new...
