British media has managed to obtain some juicy details about the next generation BMW 5-Series (G30).

The overhauled 5-Series will ride on BMW's newly developed "35up" platform set to debut in this year's 7-Series. This will enable a substantial weight loss thanks to the use of aluminum, high-strength steel and carbon fiber which will lower the mid-size sedan’s weight by an average of approximately 80 kg (176 lbs) across the range.

However, the M5 will lose much more as CAR is reporting the range-topping model will go on a massive 180 kg (397 lbs) diet. It will continue to use the twin-turbo V8 4.4-liter engine which should deliver somewhere in the region of 600 HP (441 kW), just like in the limited-run M5 "30 Jahre M5" special edition. Rear-wheel drive will be standard but for the first time BMW will offer an optional AWD system.

At the other end of the spectrum, the base version is expected to take the shape of a 518d equipped with a three-cylinder 1.5-liter turbodiesel engine rated at 150 HP (110 kW) and enabling the model to return an impressive 72.7 mpg UK (60.5 mpg US or 3.88 liters / 100 km).

We already know from a recent batch of spy shots there's going to be an even more economical plug-in hybrid version, likely with an uprated version of the hardware found in the 3-Series plug-in hybrid prototype.

BMW is currently putting the finishing touches on its all-new 7-Series flagship model set to arrive in the following months. The overhauled 5-Series will be out in 2016 in three flavors: sedan, estate and the controversial GT.
