The BMW 6 Series E63 / E64 is the second generation of the BMW 6 Series of luxury coupés, introduced in Autumn 2003 in Frankfurt Motor Show by German car manufacturer BMW. It comes as either a coupé or cabriolet (convertible) and in several engine variants ranging from a 3 litre straight-6 to 5 litre V10 in the M6 model. Production ended on July 8, 2010.
In 1989 the original 6 Series was supplanted by the more expensive and higher performance 8 Series. In late 2003, the 6 Series was reintroduced as a 2004 model as a coupé (E63) and cabriolet (E64) platforms. The E63/64 itself is based on the BMW E60, the latter which forms the fifth iteration of the 5 Series sedan.
