W213 - Driving in E mode
For the last week I have been driving in E mode and I have to admit I'm really liking it. The transmission shifts up and down are noticeably smooth even compared to C mode. Yes, the gas peddle is dampened but for "old man" driving it's become my new favorite driving profile around town.

I like E mode too bc of the gliding feature. I have this freeway I drive on and there is like a mile down downhill where in my other cars, I would place the car in Neutral to glide down hill. However, I can't figure out when the E goes into Glide. Sometimes its really happy to do it, and on that downhill tonight, it didnt.

Unfortunately you cant predict gliding mode. The transmission decides depending on many parameters icluding internal temp, speed, grade and others. You can easily tell when it happens by simply looking at the revs, if the revs drop to idle (around 800) any time you are in motion you're in glide mode. Its a nifty trick to save gas even at highway speeds beyond the overdrive gears. I would guess the "right" conditions don't happen very often or for very long.

There is no point in this. Modern cars are able to coast in drive without using fuel. But if you put it in neutral, it uses fuel to idle the engine.

How can, I put this, simply?....Um.... no. Though many cars use cylinder deactivation, if the engine speed is above idle it uses more gas then all cylinders at idle. 3 cylinders at 2000 rpms use more gas than 6 at 800. Easy math, furthermore, its not only more efficient it allows much smoother engine operation. Its operation is completely transparent. When cylinders are deactivated complex active engine mounts and shaft counter balancing is required

While what I do is becoming less effective with more overdrive gears, I believe that an engine at idle will use less fuel. Plus, its about the coasting feature. I can maintain or even gain speed down the freeway hill without needing to use more gas.

Accident avoidance via quick acceleration out of a situation is a must capability. OTOH I disengage the cruise control in the situation you describe because my car will apply brakes to avoid exceeding the cruise setting.

I don't ever put my car in neutral while underway because it is a safety issue.

^^ Ive been using ECO mode exclusively to try and track down when and when it will not glide. It will only glide above 35-40 mph, and it will only do so on flat roads. It will not do it on downward slope because the tranny likes to keep a gear lower to provide some engine braking.

My E300 has the P3 package with the second 12.3" display in place of the standard instrument cluster. When I select the "Dynamic" display screen (you can choose from three different instrument cluster layouts) and I'm driving in "E" mode, the right side of the screen actually displays "gliding mode" when the car is coasting. I really like this feature.

Closing off fuel supply during throttle off operation is not in any way linked to cylinder deactivation. Nor can you say it's simple maths since rpm is also not proportional to fuel supply. It depends on load and other environmental factors and the injection system receives only the fuel needed and no more. It's not like old carb fueled engines where the more pedal was pushed the more fuel goes in whether it was useful or not. Coming off the throttle at above idle means little to no power is needed from the engine and the wheels keep it turning without the need for fuel (some fuel may be needed to lubricate engine). Get closer to idle and fuel supply is resumed. Different operation for different cars/engines but the principle is use kinetic energy via road wheels to drive engine rather than disconnect engine and force fuel supply to turn on to keep it turning over.

It's not cylinder deactivation. That refers to selective deactivation of SOME cylinders not all of them. Here we're discussing globally cutting fuel which is not cylinder deactivation it's fuel supply deactivation if anything. No fancy balancing required.
so we're not talking about an engine cutting fuel to half its cylinders so 3 versus 6 cylinder operation is a moot point. The fact is, coasting can be less efficient than simply cutting fuel supply and leaving engine connected to road wheels. It's probably why glide mode so rarely kicks in. The computer decides when gradient and kinect energy are less efficient then decoupling engine and fueling it to a no-load idle speed.

i just discovered the E mode and love it. Much smoother ride than C.
(Sport doesn't do it for me as the suspension gets too hard.)
On my commute i get 4.3l/100km, against 5l/100km with my previous w212 CDI220
