Does anyone know the gear ratios of the GLA45? Just curious.
If you go to cars.com and put in the 2015 and 2016 versions, you can see that supposedely the ratio for your year is only 2.44, but for '16 it's now a much more aggressive 4.13, yet mileage does not change? Auto 7 spd ratios are not changed.

Something doesn't seem right there. The axle ratio couldn't have changed from 2.44 to 4.13 with same transmission ratio. If that were the case the 2016 engine would have to rev 1.69X higher to attain the same MPH.

One of the changes for the 2016 GLA45 is shorter gear ratios in gears 3,4,5,6,7. This would suggest that the axle ratio was not changed and that gears 1 and 2 did not change. It would be nice to find the actual ratios listed for 2015 and for 2016.
