Vår väg mot en optimeringsdriven kultur
In 1999, the XC90 was modelled with 300 000 finite elements.
In 2014, the XC90 gen II was modelled with 10 000 000 elements.
Detailed deformations including fractures, acceleration pulses, dummy behaviour etc. predicted well enough to lead product development process including sensor calibration.

125 kg lighter than
its predecessor.
CAD driven vs CAE–CAD integrated development
Collaboration around design space and performance analysis, many concepts and performance evaluation
Starts with earlier project and experiences, few concepts studied, time consuming iteration
