Yes, because there was a car accident in Germany. The classic Mazda 3 model broke the BMW 3 Series at a relative speed of less than 160. Mazda 3 car weight 1.3 tons, BMW 3 Series weight 1.66 tons. A typical car crashed into a big car. As a result, the owner of Mazda 3, a 49-year-old German aunt, was seriously injured, and all four people in BMW 3 Series were hanged. Rolls-Royce Phantom weighs 2.62 tons and BMW 7 Series weighs 2.28 tons, just the opposite. With the increase of collision velocity, according to the kinetic energy formula 1/2MV? The final impact energy is three times that of Mazda 3 and BMW 3 Series. It is really necessary to find the fragments of BMW 7 Series within 300 meters.
