Multi Material Lightweight Vehicle (MMLV)
Cosma International, the metalforming group of Magna, in cooperation with Ford Motor Company and the US Department of
Energy, has developed a multi-material lightweight vehicle concept that effectively achieves a 23.3% weight reduction compared to the
current production Ford Fusion.
Cosma International
Summary
The substantial environmental and fuel economy benefits gained by taking this initiative into future
production programs would be impactful on a global scale. Through the strong partnership between
Cosma, Ford, and the DOE, it has been demonstrated and proven that effective lightweight
alternatives exist today.
Engineering
Cosma reengineered the body-in-white, closures and
chassis structure incorporating new joining technologies
and an optimal mix of materials including several grades of
wrought and cast aluminum, magnesium, and high strength
steels. Vehicle performance parameters, durability, and
safety of the production vehicle were maintained.
Test / Validate
Going beyond design and build, Cosma participated in all
aspects of vehicle testing, no different than any production intent
vehicle. All crash, durability, and performance testing results met
or exceeded expectations. Concept and design become reality.
Concept and design
become reality.
Prototype
Once the vehicle design was complete,
Cosma fully prototyped and built eight
complete and drivable vehicles to be
crashed and tested. Production intent
materials and processes were used
to ensure these lightweight concepts
would meet the standards required
for future high volume production.
Innovative processes such as high pressure vacuum die
casting, hot stamping, extruded aluminum, structural adhesive,
and riveting were used in the areas of the vehicle where they
provided the maximum benefit.
