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.

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.

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.

The Backwards Man

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....
