LPG is great and I totaly agree with the concept. BUT, I would never do it on such car as a BMW 5er....... you simply do not do this.
It is a Toyota, Renault or Skoda type car solution........

otherwise it is like poor's man luxury limousine

get a nice VW and you save that 10000 EUR right there without any mods

 

You could be right, but then i ask you what are your petrol prices in your country?

 

Quote from a previous posting of me "I personaly seldomly switch to gasoline to gain more power, only when I drive at top speed ;-)"

 

Hehe, didn't mean that. Sorry my fault;

i meant when do you decide when to switch after you had your first start and/or when you already drove that day...

 

Strange opinion of you, why does BMW and other brand introduce diesels? Not because they are so powerfull, but because these engines are more fuel efficient, and the diesel is slightly cheaper.
If your opinion is true, then BMW already is a poor man's car, because the top brands like ferrari, porsche, lamborgini don't sell anything else than petrol cars.

I don't know about your country, but in 2020 every country in the EU has to meet the rule that 20% of of the cars has to be alternative fuel, like LPG or hydogen, and not gasoline or diesel. So it wil be more and more, if you like it or not, also on BMW

BMW is also one of the company's that does a lot of research into hydrogen cars

This is a link of a 7-series with hydrogen, is this also a poorman's car?

[edit] The volvo S80 is standard delivered with an Bi-fuel system[edit]

I drove a VW before, but believe me, the gasoline usage is not much better than my E60

I drove a Golf 4 and I used 8 liter on 100 km with my E60 on petrol is 9 liter on 100 km, so I have to help you out of your dream in that you can save 10K eu with a VW.

 

I think he meant on purchase price!

As far as EU regulations, I can see a huge volteface coming. Because there is no way this is going to happen. They are either going to redefine it as "20% of new cars sold", or redefine alternative fuel as including ethanol (for petrol) or biodiesel (for diesel)...

 

If he meant the purchase price, you could save more money, because a E60 in the netherlands cost 50K and a VW golf 20K

 

He didn't say Golf. He said VW:

Passat Estate SEL FSI V6 4Motion: ? 26955 (without any extras)
BMW 520d Touring: ? 27925 (without anything!!!)

(I just happen to have both Estate/Touring catalogues to hand. Guess what I bought?)

Difference: ?970 = ?1400

 

No, I wouldn't to take the chance of messing my car up with an alternative system. And, I wouldn't want to add the weight.

 

I think I don't understand the question completely

A few things (maybe that will explain more)

- The switching of LPG to Gasoline (because the LPG tank is empty) is done automaticly
- The switching of Gasoline to LPG(because the LPG tank is refueled) is done automaticly
- The switching of Gasoline to LPG(after 3 minutes after the car starts) is done automaticly
- I almost never switch from LPG to gasoline or back.
- I drive 95% of the time on LPG

I hope this answers your question.

In my opinion when you drive only 3 years with the car I wouldn't do the LPG installation, because as you notice on this forum(and it happens a lot also in daily life) people are scared for LPG, they think it will destroy there engine, that the LPG tank will explode or you would turn the car into a "pooman's car" (that one was new to me ). But most of the people are scared to use LPG but can't really explain why. If you have to sell your car, these are the questions asked. Dealers are not happy to take such car back, because they don't know how to maintain such system for the next customer.

So It would be harder to sell such car on the market.

In my case its the plan to drive this car until the next 5 series will come out. And that is in 2011 if I'm not mistaken.


There is on big benefit on those scary customers, the less persons that drive LPG, the cheapter the LPG gets.
Because LPG is a waist-product of the gasoline-refinery process LPG is so cheap.
Did you know that the burn the LPG away in the air with a gian torch when producing gasoline because there are to less of LPG drivers?
