There are a wide range of metals used in the modern race engine. Where regulations are sufficiently liberal, we may find an engine containing everything from aluminium, magnesium and steel to titanium and tungsten. In many ways the materials behave v... read more

Battery KERS

Comments (0)

When (or if) we watch a Formula One race on television this year, the commentators will probably talk about the KERS system, and how (or if) it is being used. The KERS units have yet to attain the same impressive level of reliability of the highly st... read more
