Land Rovers have used aluminium since day one but TATA have stated their aim to switch to totally aluminium bodies across the range. ...

This after Defenders have been steadily replacing aluminium with steel over the last decade or so!

I fail to see how switching to full aluminium bodies can affect to lower Co2 Emission , perhaps someone would like to enlighten me?:confused:

[WhiteD3]

Maybe due to less weight the vehicles will have a lower energy footprint. But aluminum manufacture chews a lot of electricity....but then steel manufacture burns a lot of coal.....

I find this very surprising considereing TaTa isone of the worlds biggest steel companies !

The only CO2 emissions they are worried about are the vehicle's ones while driving - because in the UK this is taxable. The lighter mass requires less energy to accelerate and hence lower Co2 emissions. The emissions associated with manufacturing aluminium vs steel components are much harder to quantify, as the answer depends very much on the assumptions made. Aluminium refining has a lot more emissions than steel manufacture - but aluminium is much more likely to be recycled than steel, as it is more valuable, and the energy requirement and hence emissions are less for recycling. Depending on assumptions made about recycling, you can get whatever answer you want.
