Horsepower is usually a good indicator, but want to know something just as good? The price. Sometimes it's hard to see where the extra dollars splurged on a supercar go until you pit them against cars from different classes. In no way is this a fair race, but that’s the point.
See a McLaren 675LT, a Porsche 911 Carrera GTS, and a Volkswagen Golf R hit the drag strip and prove that sometimes, money is what talks the loudest.
