RPMs (Revolution Per Minute) in very basic terms refers to the "power" of the car. Hence, higher RPMs gives you more power and at lower gears it is easier for the car to hit a higher RPM which gives you more torque (the "oomph" you feel when the car kicks you back into your seat).
Hence, the main difference between comfort and eco is that eco doesn't give you the power kick at lower gears and you might prefer it for cruising cause the RPMs are constant. However, for car enthusiast high RPMs at lower gears (Sports mode/Sports+ mode) give them the initial power kick which they so desire.
Overall, its really up to personal preference. Ohh and of course lower RPMs is more fuel efficient because your engine is not working as hard and less fuel burnt.
Hope my explanation not too chim and technical
Ask u all, whenever i use comfort, gear changes at around 2500-3000, the engine quite loud..
I prefer the gear to change at below 2000, not so noisy...
What is the difference between changing gear at higher RPMs (noisy, comfort) and lower RPMs (less noisy, Eco)?
I dun really feel any difference between comfort and eco but the sound level is noticeable.
I would like to highlight on a recent incident which happened to me and possibly to ALL Merc owners out there who purchased their cars from Cycle and Carriage.
I found that the solar film provided by Cycle Carriage from Huper Optics are of a different specification from what they claimed. The rear windscreen that Cycle gave me was using a Klassisch 33 instead of Ceramic 30 which they promoted. The heat rejection of a Klassisch 33 is 47% whereas Ceramic 30 is 85%. This meant that you would probably feel more heat if you were sitting at the back and although the difference may be minimal, it was still a problem because they did not provide as per promised.
For all Merc owners out there, do a check on your solar films and go to Cycle for a replacement if you realize you have the same issue!
Just saved a lovely damsell from the scrappers. No thanks to Grab Uber etc had to part with $48k for the COE on the W211.
A bit disappointed on the aluminium panels that dent as easy as a Coke can. In some ways miss my W124 whom I dumped for a prettier damsell.
FC still just as crappy at 7.5km/l even after 20 years of tech.
Plus point being it is the smallest displacement E class ever made ie 1.8L.
Initial reports few years back indicated w213 might go 1.6L in line with the other Euro models with large bodies but small engines ala Mondeo S60 etc to cap emmissions. Would have been interesting if they did, but they opted the safer route of a 2.0L, perhaps avoiding the boo boo made with W211's SBC.
Old benzs still remain my favourite.
Anyone has a Ponton?
