RE: Gear Ratios!!!!!

They must've changed it with the 7G-Tronic transmission or something.

The '03 E500 has a differential of 3.07 with the 5-speed according to mbusa.com.

RE: Gear Ratios!!!!!

For some reason I couldn't access their site earlier today. 3.07 differential it is.

The earlier E430/E420 had 2.82 differentials. But again, who the heck can go redlining in top gear in the US anyway? Acceleration is better with shorter gearing.

Gear Ratios!!!!!

ok if that's true then the V8s have a pretty good launch with the 3.07s then the 2.82. But, it has 7 speed auto so which means fuel economy is better and faster than the 5 speed [:)]

Gear Ratio

I don't know why Mercedes change the Final Drive on the E500 from 2:82 to 3:07 for the 2004. Any reasons why?

RE: Gear Ratios!!!!!

with the 3.07 nuturally you are going to use more rpm to get to any given speed, but yes you will achieve it a little quicker, these cars are not stop light to stop light racers, so when out on the road the 2.82 will need less rpm to get to the 155 limiter and probably create a fuel mileage benefit, so it seems like a toss-up between performance and economy, with a chip upgrade removing limiter out on the road a 2.82 car is going to prevail assuming both driver use the gearbox to the full potential

Gear Ratios!!!!!

yeah true, with the 7 speed you will save gas like a gallon and better acceleration. I've seen the gas range 17city and 23highway on the E500 2003s, and now the new ones with the 7 speed are from 18city and 24in the highway. I guess the top speed is higher because of the extra gears. The more gears I guess the better acceleration and fuel econnomy i guess. And yes 3.07 will give you higher rpms, but im assuming top speed will be the same.

RE: Gear Ratios!!!!!

I believe that 7th gear is still a 0.83:1 relationship. Top speed is always limited to 130 mph, so who cares between the difference of a 3.07 vs 2.82?[;)] 2.82 = better fuel economy, 3.07 = more power.
