The US and DIN/EU use different ways to measure weight, so on the German website E70 xDrive50i:
Leergewicht EU in kg = 2225
According to this spec new F15 xDrive50i:
EU in kg = 2250
So E70 25 kg (55 lbs)
lighter than F15...
But E70 and F15 are not comparably equipped, so I assume if the equipment is the same for both, F15 should be slightly lighter. Don’t forget that BMW is NOT utilizing light-weight technology for F-series, new 7-series which is G-series will be the first model with such technology.
