BMW M4 Convertible:
The convertible is the bastard child of the M3/M4 family. Convertibles invariably weigh more than the coupes on which they’re based, but they don’t invariably weigh 14 percent more. Yet that’s the gain that this 4041-pound convertible represents over a similarly outfitted M4 coupe. A 485-pound weight gain is more what we’d expect when making a convertible out of a Chevrolet Tahoe. (Why not a Suburban, you ask? Because the proportions would be all wrong.) However, there is one bright spot in the M4 droptop’s weight gain—optimized distribution of the extra pounds. Whereas the coupe carries 52 percent of its weight over the front wheels, the complex mechanism that folds and stows the three-piece metal top shifts the weight bias rearward, to the point that 52 percent of the convertible’s weight is riding on the rear Michelins.
That mechanism is certainly responsible for a lot of the extra pounds, as is the roof itself. And then there’s all that structural bracing. Cut the top off, and you have to stiffen the remaining tub. In the M4’s case, they should have stiffened it even more. With the top down, a wholly un-M level of cowl shake takes over the M4. The sturdy top lessens the quivering when raised, but even then hidden bits emit rattles.
