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 of the 50s where motorway speeds were not a consideration. These cars were driven extensively at high speeds on the Autobahns. Rather it was conscious design choice for high revving engines by Mercedes-Benz at the time. Part […]

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. Please indicate in the comments below if that is the case. The SL and SLC of the year had the same mechanical specification (at least during the SLCs production run). The only exception was the 450SLC […] 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 it to 3.07 again. The car still has its original speedometer, which means both the speed and odometer were incorrect. This page lists the different Jaguar E-Type differential ratios. There are generally two ways of accounting for the differential […] The W126 range was in production from 1979-1991. I’ve never seen a comprehensive table of W126 differential ratios, so I have attempted to create my own. 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 comes from the official technical data books. If this table is being referred to for swaps, the first and second generations diffs are not interchangeable. Neither is an ASR diff. LSD was standard on 560s but […] 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 (being delivered in South Carolina). When restored it was changed to 3.07, which was the standard ratio for cars sold in Europe. Later on, the owner before me changed it back to 3.54. This article covers the […] | |||||
