Boat-type cars are superior to Beetle-type cars in terms of appearance and performance, and also solve the problem of instability of Beetle-type cars to crosswinds. This is because the boat engine is front-facing. The center of gravity of the car is relatively forward, and the luggage compartment is enlarged, so that the center of wind pressure is behind the center of gravity of the car, so it will not shake its head and tail when encountering crosswinds. From the 1950s to the present, both the United States and Eurasia have adopted ship-shaped bodies for large cars, medium and small cars. As a result, the ship shape has become the most numerous vehicle in the world.
The rear of the boat-shaped car is stepped because of the luggage compartment. Although there are some vortices compared to the streamlined body, this is not aerodynamic retreat, but between vehicle performance, interior space and aerodynamics. Found a harmonious balance.
