Also, the 2016 RS 7 has a more powerful engine than the 2014 7 Series, and it gets 1 fewer mile on a gallon of fuel. And finally, there is a difference in the number of passengers; the 7 Series seats one more the RS 7. Among similarities are the body structure, market segment, ground shadow size, and height.
