5 things you need to know about the new BMW M5
It’s got a carbon fibre roof and is lighter than the last model
Despite adding an all-wheel drive system, the new M5 is going to be lighter than the outgoing model, which weighed 1870kg but it’s hard to say how much lighter at this stage. That said, some weight will be saved via the carbon fibre roof – the first ever on an M5 – but the roof will be steel if you opt for a sunroof. Other weight saving comes from its aluminium frame, lithium ion battery and new electric power steering, but then there’s the all-wheel drive system adding weight back in.
