OK
@Rolf and
@rs271. Here are my LONG overdue thoughts on the Audi A8 L 3.0 TDI.
First of all, the LED Matrix headlights. In a word, superb. Without a doubt I would spec these if I was ordering a new Audi which had them as an option. Compared to some useless options, these are very worthwhile as they give tangiable benefits, and benefits that you can take advantage of every day if you like. The way they lit up the fast but unlit roads at two in the morning on my drive to the North of England was very impressive. They constantly adapted, swivelled, projected, and all without dazzling other road users, both oncoming and whilst I was overtaking. It wasn't an issue when I went from Continental Europe to the UK, and therefore changing from driving on the right to to driving on the left, because the headlights were automatically adjusted via GPS when I exited the Channel Tunnel. A big thumbs up from me.
The infra-red night vision was less useful. Sure it works, but I think the amount of times you would actually make use of it are very rare indeed, which isn't great for an expensive option. Out of three days I was driving the A8, it proved useful just once, when on a dark, unlit country road, it highlighted a pedestrian in red. The truth is, the LED Matrix lights are so good that you don't actually need the night vision. I have a video of the night vision in action, but I'm at work now so I'll post later.
The radar cruise control. This was annoying. I couldn't find ANY way of just using the cruise control without the radar element, which meant it was frustrating when making progress on a motorway, only to pull out slightly too late and have the system hit the brakes without warning. This typically happened when coming up behind a slow moving lorry. On BMWs and Mercs it is possible to choose between the radar (useful when in traffic), and just the basic speed holding function.
The head up display. Not as good as BMW.
Overall I liked the A8, BUT, I still prefer the 7 Series and S-Class. The big reason is that there are just too many minor flaws in the design of several functions, such as:
The seat memory buttons are just below the internal door release handle, so about 50% of the time I would find myself knocking one of the buttons on exiting the car. When returning to the car I would find the seat has moved completely. Who designed this?!! Did they not test it before launch?!
Secondly, the usual Audi thing whereby the radio comes back on when you start the car, even though you've turned it off before switching the ignition off. Again, who decided this was a good idea?! I ended up finding out the result of a football match on the radio when I was trying to avoid the score.
Thirdly, the car had a "break recommendation" function. Bizarrely it activated within 15 minutes of setting off on my journey. Again, stupid.
The fuel economy was good (I'll update the fuel consumption thread later), and I certainly didn't need any more power.
