If you have a need for speed, this car is made for you! During a recent speed test of the Swedish sports car, Koenigsegg Agera, it reached remarkable speeds of 284 mph. Therefore, beating the previous world record by 17 mph. In a race between this car and an airplane at takeoff, the car would take the gold. However, do not run to the dealership just yet, because at $2.1 million the price tag is almost as high as its horsepower.
