Transmission ratios
Hi everyone! While waiting on my X1 sDrive18d I discovered this great forum with lot of intersting info. It seems that lot of people is following this forum and some with really impressive technical knowledge so I hope that someone can help me with following dilemma.
I was surprised when I discovered that there is significant difference in gearbox transmission ratios on s18d compared to s20d, x18d and x20d (all have same ratios)!? What does this difference means for agility and fuel economy?
Transmission ratios from official catalogue:
Gear - s18d - x18d/s20d/x20d
1(:1) - 4.00 - 5.14
2(:1) - 2.11 - 2.83
3(:1) - 1.38 - 1.80
4(:1) - 1.00 - 1.26
5(:1) - 0.78 - 1.00
6(:1) - 0.65 - 0.83
R(:1) - 3.19 - 4.64
