For the 2004 Models in the USA on the E-Class, the E500 has the final drive ratio 2.82.1 and the E55 is 2.65.1 now am I right on this. Cuz i was told different on this. Just wanna make sure if I have this correct
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.
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 [:)]
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
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.
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.
