只有輕60KG,但軸距又拉長,操控肯定是回不去了..
For 2017, the 5 Series gains a redesigned chassis and a new, lighter five-link rear suspension. Overall, it sheds 137 pounds from its predecessor thanks to the use of lightweight materials, including high-strength steel and magnesium. Nine of those pounds come from a new trunklid, which is made entirely from aluminum.

137pounds = 62kg
