PM gears conversion

Smart Fourtwo PM gears conversion

In 2008, Höganäs together with KBE+ redesigned the transmission for the Smart Fortwo car. The ambition was to create a powder metallurgy (PM) friendly, reduced weight transmission that could be built into the original transmission housing whilst maintaining reliability. 

This gearbox contains 8 PM gears, the maximum amount of exchangeable gears in that specific design. All gears have been pressed and sintered in order to achieve the highest possible density. The Smart Fortwo test car was available as a free rental to all Höganäs employees and has been used for more than 200,000 kilometres without causing any observed critical wear.
