Yes, BMW the 7-Series put on quite a bit of weight over the years as it added safety and luxury features. When a company is supposedly pushing for fuel efficiency losing weight is among the best ways to improve MPG figures. BMW is aiming to cut roughly 500 pounds off the F01 chassis with the next generation G11.
Now, do not get too excited. BMW continues to disappoint with the real world weight figures of their new cars despite their weight loss claims. That said, the G11 sure looks good moving around the Nurburgring and the cornering balance looks nice as well with it being fairly flat for a sedan of this size. The 7-Series used to be the choice for the person who wanted to drive their luxury sedan, not be driven. So far the G11 7-Series is looking good in that respect.
