2.2 Liters/100 km gas consumption is that possible?

i am going to buy a 2nd hand M5 (BMW 530)
the previously owner claim, it has a very low fuel consumption, -
something about 2.2 to 2.3 liters per 100 km...

is that technically possible..?

For normal driving..... no. The 530 is way too big to come anywhere close.

The Smart For Two car is half the size and weight of the 530, with half the engine size, and a diesel to boot...... and it gets 4.2 liters/100 km.

There is no way a 530 can double the mileage of a Smart

you means the 530d (the diesel engine one) may have it,
and the gasoline - not...?
or i got you wrong ?

No 530 (diesel or gasoline) can get 2.2L/100km in normal driving.

If a tiny diesel car like a Smart car can only get 4.2, why do you think a much larger 530 can get twice the mileage?

No 530 (diesel or gasoline) can get 2.2L/100km in normal driving.




Hm, this is very interesting how to get it...
Till now I was try few different technologies of the power saving but only one of them works for me.
I reach some results, but 2,2L/100km was possible with one technology only.
How I can have that power consumption without any technologies, with normal driving only?

1. Always drive downhill with a very strong tailwind.
2. Install a very powerfull electromagnet in the front bumper. Get behind a large truck, etc, and get towed.
