How It Works

  • BMW M5 acceleration

    The 0-60 mph time has been a measure of performance for a long time and cars have continued to reduce their times over decades. BMW decided to explain what goes into shaving seconds off of a 0-60 mph time and it involves a few key areas. The basics show that all of the power a car has needs to work against all of the weight the car carries. That's a very bare look at the topic, but it's a good starting point from Sir Isaac Newton. However, we the arrive at aerodynamics. Aero drag rises with velocity, which means drag increases the faster a car goes. Drag is an important factor when it comes...
