“Then there’s where the opportunity is, and there’s about 15-20kg because of more complex systems on the cars and there’s about 30-35kg on car dimensions. So cars being much longer and wider, bigger tyres and so on.
“And we believe in the car dimensions there lies an opportunity. We would want 2026 cars to be quite a lot shorter and probably maybe a bit narrower as well and all of that is going to contain the weight increase."
So he mentions the larger tyres along with the length and the width as part of the dimensions where an opportunity lies for weight loss. Perhaps the first hints of smaller wheels and tyres being considered for 2026?
More weight reduction would be possible with different powertrain choices, but the desire to have a very large electric component to allow a soft landing towards full electric in the future, makes sure the weight reduction is limited to about 35kg as pointed out in the article.
