Powder Metallurgy could benefit from challenges to increase fuel economy of US cars

August 8, 2011

The Obama Administration unveiled new fuel economy rules in Washington last week which will require car manufacturers to achieve a new ‘corporate average fuel economy’ (CAFE) of 54.5 mpg for all cars in the USA by 2025.

Currently CAFE standards call for 35.5 mpg by 2016.  The new CAFE targets will force car manufacturers in North America and importers to overhaul their approach to vehicle design, and also engine and transmission design, using lighter materials. 

Powder metallurgy could benefit from the challenge by offering the automotive industry lighter weight high strength steel components, and also PM aluminium and PM Al MMCs plus PM titanium and titanium alloys, which have the ability to dramatically reduce weight of engine and transmission parts without loss of performance, and hence improve fuel economy.
