accurate weights are listed on the car data carrier, along with the colour codes.
Also in the CoC docs.

I think Martin Brundle went the same way!Always makes me wonder how the F1 teams spend millions saving every nanogram on a vehicle, then allow the drivers to grow trendy face fur...surely they would be better asking them to be close shaven if not totally hairless like cyclists are!!!!I think the reason I have never been approached by racing team is because I like sausage butties too much...that's my reasoning anyway.
I once gave a talk on the A2 and as a group exercise ask the audience how they would take a diesel A2 with combined 78mpg and make it into a 100mpg (like the 3L model). I then showed how the A2 designers did it through weight reduction, drag reduction, power reduction and behaviour reduction. Here is the weight reduction slide:This thread makes me think - I've read a lot of threads on aero mods, but very few if any on weight saving.
From my experience of other cars, unless you're willing to strip out the interior, removing rear seats etc, it's very expensive to save a few kg with carbon fibre parts or such like.
But nevertheless it would be a fun project to read to see how light someone could get a road legal A2.
Nice picture, thanks you.I once gave a talk on the A2 and as a group exercise ask the audience how they would take a diesel A2 with combined 78mpg and make it into a 100mpg (like the 3L model).

The kg figures are the weight reductions where kown.

Any idea Bret how that was achieved?shell is 15kg lighter, too, that was given at a presentation in Neckarsulm a few years back.
Nice picture, thanks you.
But it could be interpreted as front disc are in aluminium, not sure that is correct. The wheels are often referred to as being magnesium, but actually is mainly aluminium. But still a very impressive engineering result, this car .
I wasn't present. Some thinner parts, some parts excluded, I believe. EDIT says there are some comments somewhere on the German forum, it would be an effort to drag them out. I will have a think about some keywords for it.Any idea Bret how that was achieved?
Well, I shall admit have not analyzed the material in a lab, so I dont have that confidence level. But I have read about it, and I managed to find this now:@Joga
are you absolutely shore those rims are not made of AZ91, which we sold to VAG and Porsche for their prestige rims at that time.
AZ91 is 90% Mg and 9% Al and has a density of 1.81 compared to Al which is 2.7 ish it sounds weird to not use that potensial ....
By using Az91 instead of Al, let 30kg become 20kg.... sounds like a dream to me for a designer lead working to achieve "der 3L auto"
cheers
