Driver Profile Selection - Coasting Function

[Baz 55]

I'm not sure if all Mk 7 with DSGs have a coasting mode or mine has because it has a DA pack BUT -
I am becoming quite an expert in coasting and am freaked out just how far the Dub will coast for.
Around the area I live I have learnt to take my foot off the accelerator sooner and sooner now realising the potential of coast mode.
I have traveled 3000k and mostly urban and outer urban driving and am currently averaging 5.2l per 100km in economy mode. I reckon this is really good and put a lot of it down to the ability to coast a lot.
Is anyone else using Coast mode ?
How is it going ?

the coasting is amazing... so is the auto hold brake... i'm going to be such a lazy driver hahaha

Loving the coast. Have been getting great fuel consumption between that and the cruise control around Canberra (conditions well suited to use of both). Not sure the standard models (without driver assist) have it...certainly the shifter is only labelled D/S (not D/S/E; the three modes on mine).

Turned off the auto hold brake incidentally...perfer the start/stop to activate the engine when I take my foot off the brake (gives it a little more time to react before I take off). The start/stop was the one thing that annoyed me in the test drive, so I was glad to discover it was able to work this way...

Mine is a manual and assume it doesn't have coast mode but I've really had to adjust my driving technique to account for the way the car just keeps rolling and rolling along after lifting off the accelerator. It feels like there is no wind or road resistance at all. It's such a contrast to the Forester I also drive which feels like the brakes have been applied when coasting.

Yep, even my mk6 AWD, also a manual, coasts a hell of a lot better than my old MY01 WRX. I guess it just has a lot less rolling resistance, even coasting in a low gear like 4th (thinking down Warringah Rd over the Roseville bridge where you can be breaking the speed limit in 4th with zero throttle. Looking at the instantaneous fuel used in the MFD, it is nice to see zero for so long while maintaining a high speed

So what's new? I had a 1950's Rover with selectable freewheel — which also made clutchless changes a doddle.

Plus in the 1940's lived at the top of a long hill.

My 1923 Dodge would roll about a mile and a half with the motor turned off and went faster — and ever so much smoother — than it could under power (alas, rolling in "angel gear" is now banned...)

Idle - by name and by nature - a conservationist well before your time. lol
My first car was a VW Beetle 1962 an absolute piece of crap and it rolled heaps !!!! However I had to push it - a lot

[GeckoZAO]

yeah loving coasting, but isnt it similar to N gear for manuals when rolling (just guessing, be nice!!! XD)
i live in the cbd, 500kms done so far, 8.4L/100km average speed 24km. so sad...

I use to drive my Mk 5 2.0 TDI DSG like it had coast mode (manually selecting N). But from what I've read in the manual, and road rules, it's now illegal to do so. (And apparently bad for the clutch?)

[tonymy01]

The N gear uses fuel though (as in, for the engine to run, it runs at idle in N, you can see the MFD shows litres/HR on the instantaneous view), the coasting I was referring to was in gear,foot off throttle, the engine shuts off fuel entirely (as the engine is being kept rotated by the drivetrain).

That's how my manual works. In neutral it uses .5L/hour with aircon off and .7L/hour with aircon on. When lifting off in gear it shows 0L/100km and feels like it's going to roll on forever.

btw The other day my touchscreen showed 227km travelled in 2.53h at 79km/h with 980km range and average 4.5L/100km. Just typical country driving with other traffic at speed limits. I reckon that's pretty good for a petrol engine. It makes me wonder if it could ever do 1200km on a tank full like the readout predicts.

[tonymy01]

The only way I can imagine this works given the engine has quite high compression is that it somehow opens the exhaust valves early to reduce the compression during the compression stroke.

The way I get the car to roll further is foot off the accelerator and push the gear stick into s mode. It will hold the gear box into higher gear and will not down shift so soon.

wow, impressive!
i hope mine gets low soon after run-in, 500km so far, 28km avg and 8.4L/100km.
keep it up!

[GeckoZAO]

noticed sometimes when im coasting downhill at 70-80km/h, there is no 'eco' icon on MFD, and engine rev is about 3k, consumption was showing 0L/100km. so why it keeps rev up instead of like coasting when rev is under 1k?
