Abstract
In a group of motor vehicles of one vehicle type, hybrid-drive motor vehicles are derived from the electric-drive motor vehicles. By using the architecture of electric-drive motor vehicles for the hybrid-drive motor vehicles, the architecture has a floor pan subassembly that sits in a higher position in comparison to that in motor vehicles having an internal combustion engine drive. An installation space for housing a battery on the underside of the floor pan subassembly is made available, which, in comparison to the motor vehicle in the prior art, allows significantly larger batteries to be housed.
Claims19
A group of motor vehicles of one vehicle type, comprising:
- motor vehicles with three different drive concepts, wherein
- the three different drive concepts comprise a combustion engine (“combustion drive”) or an electric motor (“electric drive”) or a combination of a combustion engine and an electric motor (“hybrid drive”),
- two different floor panel subassemblies are provided, wherein a first floor panel subassembly, in an installed position in the motor vehicle, is arranged higher than a second floor panel subassembly, wherein
- a bodyshell structure of the motor vehicles with the electric drive and of the motor vehicles with hybrid drive have the first floor panel subassembly and
- a bodyshell structure of the motor vehicles with the combustion drive have the second floor panel subassembly, and
- the motor vehicles with the electric drive and the motor vehicles with the hybrid drive have at least one battery arranged over a large area under the first floor panel subassembly,
- wherein two different front-end subassemblies are provided,
- wherein floor regions of the bodyshell structures of the motor vehicles are formed, in a manner dependent on the drive concept, by a combination of one of the two front-end subassemblies and one of the two floor panel subassemblies,
- wherein the two front-end subassemblies have front longitudinal members, and
- wherein:
- in the case of a first front-end subassembly, the front longitudinal members end in the region of a bulkhead without continuation in a member structure at the underside of the floor panel subassembly, and
- in the case of a second front-end subassembly, the front longitudinal members are adjoined by central longitudinal members which extend into the region underneath the floor panel subassembly.

A method for producing a group of motor vehicles of one vehicle type, wherein
- the group comprises motor vehicles with three different drive concepts,
- the three drive concepts comprise a combustion engine (“combustion drive”) or an electric motor (“electric drive”) or a combination of a combustion engine and an electric motor (“hybrid drive”), and,
- to form floor regions of the bodyshell structures of the motor vehicles, two different floor panel subassemblies are provided, wherein a first floor panel subassembly, in its installed position in the motor vehicle, is arranged higher than a second floor panel subassembly,
- wherein bodyshell structures of the motor vehicles with the electric drive and of the motor vehicles with the hybrid drive are produced using the first floor panel subassembly,
- the bodyshell structure of the motor vehicles with the combustion drive concept are produced using the second floor panel subassembly, and
- in case of the motor vehicles with the electric drive and the motor vehicles with the hybrid drive, at least one battery is arranged over a large area under the first floor panel subassembly,
- wherein two different front-end subassemblies are provided,
- wherein:
- floor regions of the bodyshell structures of the motor vehicles with the electric drive or with the hybrid drive are formed by combination of the first front-end subassembly with the first floor panel subassembly,
- the floor region of the bodyshell structure of the motor vehicles with the combustion drive is formed by combination of the second front-end subassembly with the second floor panel subassembly,
- wherein the two front-end subassemblies have front longitudinal members, and
- wherein:
- in the case of the first front-end subassembly, the front longitudinal members end in the region of a bulkhead without continuation in a member structure at the underside of the floor panel subassembly, and
- in the case of the second front-end subassembly, the front longitudinal members are adjoined by central longitudinal members which extend into the region underneath the floor panel subassembly.
