We’ve gotten really good at cheating physics. Even though cars are getting much heavier, the technology to hide their weight is getting much better. Adaptive and active suspensions, torque vectoring, electronic differentials, traction and stability controls, and ever-better brakes and tires all make cars seem so much lighter than they are. A new BMW M3 weighs around 4,000 pounds, but you wouldn’t believe it by the way it flits into a corner on track.
