FEV, Inc. Completes Vehicle Mass Reduction Study for EPA
Project demonstrates company’s competence in overall vehicle dynamics
Auburn Hills, Mich., December 13, 2012 – FEV Inc., (FEV) a leading developer of advanced powertrain and vehicle technologies, announced today that it has completed a Phase 2 Light-Duty Vehicle Mass Reduction and Cost Analysis Study under contract to the United States Environmental Protection Agency (EPA). The Mass Reduction Study follows up on an earlier, independent, phase 1 study by a third party for the International Council on Clean Transportation. The results indicate that, when mass reduction strategies are considered using a full-vehicle approach, significant mass reduction (approaching 20%) can be achieved assuming comparable performance, including crashworthiness.
FEV was selected for the study based on its position as a long-time EPA research partner, and the experience it gained in conducting a cost analysis of the development and operation of fuel efficient powertrain technologies. That program involved determining the incremental direct manufacturing costs for a set of advanced light-duty vehicle technologies. The same costing methodology was applied to the Mass Reduction Study.
“FEV is perhaps best known for our capabilities in powertrain design, development and calibration,” said Gary Rogers, president and CEO of FEV, Inc. “However over the last 15 years, we have significantly expanded our work in vehicle engineering and production cost reduction or value engineering. The combination of this experience in powertrain and vehicle development gives us a rather unique ability to tackle future challenges related to cost effective solutions for meeting fuel economy and greenhouse gas mandates.”
FEV’s Mass Reduction Study builds on the phase 1 analysis in several ways, including (1) incorporating powertrain mass-reduction ideas which were not part of the phase 1 analysis, (2) utilizing advance computer aided engineering tools to develop and validate the mass-reduction modification to the body-in-white structure, where mass-reduction could have significant impact on vehicle safety, and (3) determining the net incremental direct manufacturing cost impact of vehicle mass-reduction.
The project, which used a 2010 model year Toyota Venza as the baseline vehicle, targeted a vehicle mass reduction of 20 percent with direct manufacturing cost impact of 0 percent for a 2017 – 2020 model year program. FEV considered all components and assemblies in the Venza systems and subsystems as available options for mass reduction, but no functional or performance degradation was permitted from the baseline vehicle. The Venza was the same vehicle-type used in the Phase 1 study to ensure optimal continuity between the two studies.
Analyses for the project began with the evaluation of mass reduction opportunities presented in the phase 1 report. Investigation of additional mass reduction opportunities -- including those not covered in the original report -- namely powertrain/vehicle systems, were included in the final analysis by FEV.
All ideas were evaluated in terms mass reduction magnitude, incremental manufacturing costs, incremental tooling cost impact, product function and performance degradation risk, manufacturing feasibility, and 2017+ production year readiness. Design, material, and manufacturing processes likely to be available for the 2017 – 2020- model year timeframe were considered in the mass reduction technology analysis.
For the midsize crossover utility vehicle, a 312kg or 18.3% percent vehicle mass-reduction was achieved. The vehicle systems which provided the largest contribution to vehicle mass-reduction included: body-in-white by 12.9% (4% of vehicle), suspension by 27.7% (3.9% of vehicle), body interior (e.g. seats, instrument panel, interior trim) by 19% (2.5% of vehicle), followed by brakes, engine and transmission systems contributing a combined 4.8% vehicle mass-reduction.
Over the long-run, the cost impact of these new technologies, when combined with secondary mass savings, is also expected to result in an overall reduction in vehicle direct manufacturing costs. To achieve an 18.3% vehicle mass-reduction, the analysis suggested a net incremental direct manufacturing cost savings of $148 per vehicle with an increase in tooling cost increase of $23 million dollars.
