Can someone please tell me what the bluemotion stands for on some VWs

thanks

When the engine is warmed up enough and the vehicle comes to a stop the 'Bluemotion Technology' kicks in and shuts the engine off. When you press the clutch pedal down again to put it in first the engine quickly turns on again.

It saves fuel - avoids having an engine ticking over when you're stopped at lights or in gridlock traffic.

Don't think the Blue Motion tag applies only to the engine cut out mechanism.

It's all the fuel and efficiency savings that are put into the car. I think the engine is tuned differently and the gearing is different than a standard car to get better mpg.

tf2

Low resistance wheels too AFAIK

Special Circumstances

Different gearing for less acceleration but more efficient cruising. Aerodynamic mods in the case of the polo. Depends on the model.

All the above plus the car is lowered by 15 mm .. got around 62 mpg on a mark 6 Golf the mark 7 now has a six speed gearbox also underneath the car is fared in to reduce drag ..

I travelled from Galway to Portmagee in Co. Kerry and back and got 75mpg according to the car trip computer. That's in a 2 door golf Mark 7 with a 90bhp 5 speed gearbox.

For some reason manufacturers use blue to denote their efficiency packages so:
Mercedes-Benz has blue efficiency
Hyundai has blue drive
VW has blue motion
I think other companies have different names too like Toyota's eco drive. What the package consists of will depend on the exact model of car. But it could include things like tyres and gearbox as mentioned above or less sound deadening material to reduce weight, shift light to indicate when to change gear for best economy, removal of spare wheel, cylinder deactivation etc.

That's really impressive, especially given the level of comfort and safety in the mk7. Was that model badged as blue motion?

I presume your query extends to the all important fuel consumption

I've a 13 1.6 Passat. I've the blue motion on. Tank avg is 4.8l/100km.

It's the best 'long' journey i've recorded on it so far. It was a mix of motorway speed and 80-100km roads. Bit slow at some parts on the 'Ring of Kerry' section - Tourists taking photos and what not.

Yeah, badged as a TDI Bluemotion on the back.

Just to confuse thing's more there is a difference between Bluemotion and Bluemotion technology .. Bluemotion cars have all the fuel saving equipment and Bluemotion technology only has stop start ..

All the new VWs seem to come with "Bluemotion technology" but you also have one car in each model that is a "Bluemotion" car. This includes , no spare wheel to reduce weight(puncture kit instead), reduced bhp for engine efficiency, and other things i cant remember.

"When you're trying to save energy while driving it makes sense to recover it where you can. One way we've done this is to raise the alternator voltage when slowing down and braking. This increases battery charging and helps the car slow down. The alternator load is then reduced when accelerating to lighten the burden on the engine and cut fuel consumption. Recuperation is a feature of some of our BlueMotion cars."

Interesting. I know a man who thought his vw passat bluemotion alternator wasnt charging, as the voltage output was only ~ 12V when he was testing it. Seems the alternator will only put out full charging voltage, when it knows the car is braking or slowing down.

tf2

Ever become frustrated by drivers who don't seem to move up like they should in slow moving traffic? Bet its a car with Bluemotion (or any stop/start, Blue Drive, DrivE system).
When the engine cuts off sometimes drivers will let a gap build up before putting it back into gear and moving up. Once this was pointed out to me I seem to see it everywhere!
My latest pet hate.

If he turned on aircon or headlights he would see the voltage come up to normal probably, but in a situation where there is only a small electrical load it probably stays around 12 to reduce the load the alternator puts on the engine. There are various flavours of smart alternators around for many years. Although there are certain posters on here who will tell you "that's a load of rubbish". LOLz

Thanks Everyone for all the replies so it seems to be totally related to fuel efficiency

Volkswagen are bringing out a new petrol Bluemotion with a 1 litre 3 cylinder tsi engine 115 ps 200 nm of torque six speed manual or 7 speed dsg . Supposed to do 65 . 7 mpg .. so 50 mpg is probably a more realistic figure ? Will this car be a proper alternative to a 1.6 Tdi ??

i.e. poor grip tyres!

Is this in relation to the 3 cylinder engine used in the UP!

It's all marketing. They're cutting down on fuel use to meet strict emissions targets from the EU. They're selling it as "Bluemotion". It means nothing. They just don't stick it on the GTi!
I know of brand new VW's with full size spares and regular tyres on them, yet badged "bluemotion", so all fluff to get people thinking that with that badge they can get 80mpg...

Every driver I know with a start/stop car disables it at the first intersection they come to. Most complain that it can't be disables permanently. Most pointless Eco technology I've seen in real life.

NIMAN

Do you think you can trust the trip computer on your car to give am accurate reading of your mpg?

I drive a 1.6 Economic Focus, and mine is currently reading 64.7mpg, which I think is pretty good. Just don't know whether to actually believe it or not!

You can switch it on or off anytime you like on a Golf....

I have it on mine and it works seamlessly so I use it all the time, you barely even notice the engine has switched off and you barely notice it cutting back in when you go to move off.

It's really not. The engine restarts the second you engage the clutch. And it only kicks in when you put the car in neutral so if you're first in line at the lights you just leave the car in gear, seemples.

If you're sitting long enough for the engine to cool or open the door do you not have to start with the key then? I always have it switched off even before I have the belt on.

Unless you have the automatic (DSG) version....

Sounds like a good but realistic figure, I believe those trip computers are more accurate now than they used to be. I would use the tank brim and empty method a few times while comparing it to your dash readout, should give a good idea of what percentage error the computer gives.

I heard an add for the new Honda civic earlier claiming it got over 100mpg!

Surely that just defeats the purpose of having it in the first place?

There are 3 seperate fuel consumption figures displayed on the mfd .. since refuel .. since start .. long term .. i go by the long term figure which is probably the most realistic ..No problem getting over 70 plus mpg on the since start screen ..

The auto is a pain in the nuts with this system. It turns off the engine before you've completely stopped, and because you don't have a clutch to operate, you notice the delay in starting much more.
Also, if you open the door and then move the lever into Park, it gets itself in a knot and the engine management light comes on!

Was about to disagree but... My turbo has been replaced already... car is about 4 months old! Sure its an isolated incident though

Did they say what the failure was? Shocking if it was ok leaving the factory and failed in the field in that space of time. Surely it was some manufacturing issue.

What happened was twice (on the same day) for a very brief moment the turbo didn't kick in. This was at about 13500km. It didn't happen again. The car was due in for a service at 15000km so I mentioned it to the garage and asked them to look into it. They ran a diagnostic on it and saw that there was an 'intermittent fault' showing. It was replaced under warranty and they gave me the use of a vehicle while the had it in (fri - mon).

At 28000km now and no problems.

Lucky enough if that sorted it. I've had my heart broke with enough intermittent faults on turbos over the years, and it more often than not was nothing to do with the turbo itself.
