Model S is equivalent to a 7 series, not a 3 series. P100D is 4960lbs, 750 xDrive is 4623. That’s not 40% heavier.
Finish, comfort handling and in many other ways it’s much lower than the high end series 3/5 yet alone 7.
BMW just like Benz has a big overlap between its series.
The model S is an amazing car but it’s handling is subpar mostly due to its weight and it’s furnishing is a joke compared to even entry level luxury sedans.
I saw a talk from the data guy at Progressive car insurance, he said that the only signal from their "black box" monitoring of drivers (opt-in) which predicted accidents was extreme braking. Not strong acceleration, not anything else.
That said, my driving instructor said "if you use your brakes on the autobahn in normal driving, you are doing it wrong". That is because you can see far and air resistance slows you down quickly enough.
High performance sedans, such as the Model S and F10 M5 don’t just need big brakes because of their speed, but also their weight.
2 piston calipers up front on either of those cars would be dangerous. What happens if the driver has to make a sudden stop? For this reason sedans and SUVs tend to have at least 4 piston calipers up front, 6 for performance models.
Never have I thought for a second, on road or on track, “Gosh.. I wish I had crappier brakes”.
You could compare a P100D to an F10 M5, which is 4,288lb - almost 600lb lighter than the Model S.
I didn’t realize the 7 had grown so much (126” wheelbase is nuts)
I really don’t see that many problems with comparing the Model S to either tbh.
