Fisker Automotive used virtual prototyping to design the rear structure and other areas of its Karma plug-in hybrid to ensure the integrity of the fuel tank in a rear end crash as required for Federal Motor Vehicle Safety Standards (FMVSS) 301 certification.[8] Agilent Technologies used virtual prototyping to design cooling systems for the calibration head for a new high-speed oscilloscope.[9] Miele used virtual prototyping to improve the development of its washer-disinfector machines by simulating their operational characteristics early in the design cycle.[10] Several CAE software solutions (for example, Working Model and SimWise) offer the possibility to check the benefits of virtual prototyping even for students and small companies, and collection of case studies are available since 1996.[11]
