Hello,
You are invited to participate in the FEV Driveability Questionnaire. Approximately 20 people will be asked to complete a survey that asks questions about objective and subjective driveability. It will take approximately 30 minutes to complete.
Your participation in this study is completely voluntary. There are no foreseeable risks associated with this project. However, if you feel uncomfortable answering any of the questions, you can skip the question and continue. It is very important for us to learn your opinions.
Your survey responses will be strictly confidential and data from this research will be reported only in the aggregate. Your information will be coded and will remain confidential. If you have questions at any time about the survey or the procedures, you may contact Thomas Wellmann at 248-724-2860 or by email at [email protected].
The survey results will be aggregated and published without attribution in a report that will become available to the responders when completed in 2017. Responders to this survey could use this report to contrast and compare their vehicle rating techniques to others being used in the industry.
Thank you very much for your time and support. Please start by filling out your contact information below then clicking the Next button. |

About CRC
The Coordinating Research Council (CRC) is a non-profit organization that directs, through committee action, engineering and environmental studies on the interaction between automotive/other mobility equipment and petroleum products. CRC research programs are managed by five technical committees (Advanced/Vehicle/Fuel/Lubricants, Atmospheric Impacts, Emissions, Performance, and Aviation.). CRC is not involved in any way in regulation, nor is CRC involved in the development of hardware or petroleum products. The formal objective of CRC is to encourage and promote the arts and sciences by directing scientific cooperative research to develop the best possible combinations of fuels, lubricants, and the equipment in which they are used, and to afford a means of cooperation with the Government on matters of national or international interest within this field.
