Next BMW 5 in addition to 3 Series to benefit by lightweight tech
The next 7 Series is actually set to be some 200kg lighter than the current car
fresh 7 Series’s lightweight materials are likely to be used on the 3 in addition to 5 Series too
The next generation of BMW’s 5 Series in addition to 3 Series will be able to use the advanced carbonfibre in addition to aluminium construction techniques by the forthcoming 7 Series, according to comments by senior company insiders.
The next 7 Series’ chassis mixes carbonfibre, aluminium in addition to high-tensile steel in a manner in which, BMW claims, “no different company could produce right at This specific point”. The techniques wipe 40kg by the bare Centeng in addition to the use of aluminium in different key areas increases the total saving to 200kg, although extra sound deadening in addition to safety kit reduce the net gain to 130kg.
Three types of carbonfibre are used – braided, layered in addition to raw ‘recycled’ fabric – depending on the directional rigidity required.
BMW’s first two carbonfibre-focused production cars, the i3 in addition to i8, were hit by early production snags as the firm struggled to stitch together a complex workflow of which involves two plants in Germany, one in Japan in addition to one from the US.
However, a senior 7 Series project insider told Autocar: “Arguably, the biggest achievement with the 7 Series is actually the industrialisation of these processes. We have learned many lessons by i3 in addition to the carbonfibre components are not the limiting factor from the speed of 7 Series construction.”
Asked if This specific could allow the same processes to be used for smaller types, the source said: “of which’s not a simple question although, from the broad sense, yes.”
Scaling up the use of the lightweight materials for the 7 Series is actually a solid achievement. although using them for volume types like the 3 in addition to 5 Series will be a further challenge.
However, lightening the next versions of these cars is actually key to improving their fuel efficiency, allowing the use of smaller engines in addition to fitting batteries to plug-in hybrids of which allow longer electric-only running.
