“Finally, at the end of the vehicle’s life, this big chunk of aluminium is a great asset and something you can bring back again in another loop to reuse that material.”
When can we expect this process to begin?
“Mega-casting will be introduced with our fully electric platform and it will be put into production in the middle of the decade.”
How do these parts affect the performance and drive of a car?
“I don’t think you would see much of a difference – it would reduce the weight a bit. When it comes to stiffness, we’re fulfilling the requirement we have so it would be the same if it was steel.”
How about the efficiency of your electric models?
“In production you would get an increase in efficiency, but more importantly what we have seen is that when you cast a structure you can sculpt tighter around your wheels, suspension, powertrain and the seats compared with steel.
“By going tighter, you can, for instance, lower the seat by around 15mm. You can lower the roofline, and then you reduce the complete cross-section of the car. That has a big influence on the range and that is more significant than what you get from the weight reduction.”
What are the first models we can expect to be manufactured this way?
“The model has not been presented externally yet – the only thing we can say is that it’s coming with this new electric platform around 2025.”
Does the battery plant support the construction of the batteries themselves?
“This mega-casting has an interface with the battery. The rear part of the battery is attached to this floor, but otherwise there is no connection right now.”
Are there any significant monetary savings to be made using mega-casting?
