Albert Einstein posited that energy is equal to mass times the speed of light squared. The Mercedes Benz CL65 AMG provides a new definition: energy equals horsepower at the speed of light for squares. Relativity speaking, the big Merc's top end is significantly less than the cosmic speed limit of 670,616,629.384 mph. Subjectively, that number feels about right. In fact, the CL 65 is Die Grosse Bang on wheels, an automotive event that warps the time space continuum to the point where I swear I wrote this review tomorrow.
