manicm:Sorry TegTypeR, have to agree with others here, your question is rather superfluous.
It is far from a superfluous question.
How many people have stood there and said, "My A8 isn't quite big enough"? How long before the car out grows the average European parking space? How long before we all run out of road space? Where does it all stop, cars are growing at an alarming rate? All relevant questions.
Yes, you may be right, they may be considering dropping the LWB version - some how though I doubt it. I'm sure the argument will always be, BMW and Mercedes do a LWB version of their executive saloons, so we will too.
The current car stands at 5062mm long. The proposals, according to the article, says the new vehicle will be 5162mm (approximately). Let's get that in perspective. A Hummer H2 comes in at 4826mm long. Even the eight seat Hyundai i800 people carrier comes in at 5125mm, less than the proposal for the A8.
In reality the reason it will need to grow because vehicle packaging is becoming lazy. An extra inch sound deadening here, or a couple of millimetres of foam there, it all starts to add up. If that 100mm or 4 inches meant there was exactly the same amount of extra room for the occupants then fine. But it won't happen like that.
I'm not proposing we should be dictated to by the car police - far from it. What I want to see is companies such as Audi (and I'm not singling them out for one minute), thinking about what they are doing.
Phew.... rant over.
It's all about the twisties....
