At what speed does drag matter?

1 Answer:
  • Travis Bickle
    At speeds over 9 mph, it's the dominant force of resistance. By the time you hit about 30 mph, 90 percent of your power goes into overcoming air resistance, or what scientists call aerodynamic drag.19 oct 2021
  • What's the most aerodynamic shape?

    For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
  • Do lowering springs increase mpg?

    Lowered vehicles are more aerodynamic. There's less air hitting the wheels and tires (that are not streamlined shapes). This makes these cars faster. Some owners of low-stance vehicles also notice improved gas mileage.

  • What body type is a 4X4?

    SUV (Crossover / 4X4 )

    The term 'SUV' stands for 'Sport-Utility Vehicle' which doesn't really help explain what it means and is why it is one of the most confusing car body style terms used today! An SUV was originally used to refer to cars that were rugged, sturdy and that included four-wheel drive for off-road use.

  • Do aero helmets make a difference?

    Clearly an aero helmet does make you faster by a measurable amount, but it's not quite free speed because the reduced ventilation means you pay in heat build-up. Unless you live in a cold climate, we would probably not recommend an aero helmet for use as your sole, everyday lid.
