Right, the word is proportion. The 6 has a proportionally lower roof line than the 3 series. It is also much sleeker of a line. The difference is actually measured in centimeters and a lot of it is the sleekness.
The 1 series is 10 centimeters shorter, yet has a 4 cm higher roof line. The result? Well you can see the result.
