The 8 Series Convertible is 258 pounds portlier than the coupe, at just over 4,700 pounds. Weight-loss efforts include employing aluminum for the doors, hood and firewall, and carbon-fiber reinforced plastics used for the center tunnel.
The trunk holds 12.4 cubic feet of your belongings, which is less than the coupe's because the soft top folds into the trunk. That cuts down on vertical room, so you'll probably want soft-sided bags for your weekend getaways.
One great feature for extending your roof-down season: a button that turns on a blast of warming air that emerges from the front-seat headrests. The car also has heated seats and a heated steering wheel.
About the only downside to living with the M850i every day is fuel economy. It's rated for 17 miles per gallon city and 26 mpg highway... but driving enthusiastically netted me 16 to 17 mpg even in mixed driving.
