Today they are doggedly pursuing a 'virtuous cycle' where lightweight body structures, 'right size' powertrain and chassis, downsized power plant with enhanced performance and electrification delivers improved CO2 performance. Critical to making this change is the role of lighter materials. This transition, according by a US study carried out by UC Davis for the California Air Resources Board (CARB) is actually made more difficult by the widespread introduction of hybrid vehicles, which have an average weight increase of 9% over their non-hybrid counterparts, pointing to the enhanced importance of lightweighting measures as vehicle electrification strategies progress.
This second edition report looks at policy initiatives, weight saving methods, competition between OEMs, barriers, drivers and government regulation. Fuel economy & CO2 emissions are detailed for the US, EU, Japan, South Korea & China. Vehicle safety & cost implications are also considered along with weight reduction by sector (body structure, chassis, powertrain and interior).
The report also includes a detailed section on materials technology and examines the use of advanced steel, aluminium, magnesium, titanium, carbon fibre, plastics, bio-materials and textiles. Recycling and joining technology are also considered.
