A streamlined object will cut through the air with less resistance, just like a sharp knife cuts through materials better than a dull one. Streamlining means less aerodynamic drag and therefore less fuel is needed to propel a car forward.

What is the most efficient shape for a car?
The most aerodynamically-efficient shape for a vehicle is, in theory, a teardrop. A smooth shape minimises drag and the profile, if correctly configured, keeps airflow attached to the surface rather than breaking free and causing turbulence.
Why should cars be streamlined?
A sports car is long and smooth - streamlined. The air can slide over it quickly. In a more flat-fronted vehicle like a truck there is much more air friction. ... So, with both air and water, a streamlined shape reduces friction and helps the boat or car go quickly.
Why does a streamlined car use less fuel than if it was not streamlined?
The more streamlined or “slippery” the shape of the car, the easier it will be able to push through the airflow. If its easier then it requires less fuel to achieve movement.
Why are modern cars streamlined?
Cars are given streamlined shape to reduce air resistance. A car with streamlined shape move through air easily and hence consumes less petrol. More streamlined the shape of car, less petrol it will consume.
What is the most streamlined car?
2022 Mercedes-Benz EQS Edition One is a flashy, techy electric flagship.
How are cars streamlined?
A streamlined object will cut through the air with less resistance, just like a sharp knife cuts through materials better than a dull one. Streamlining means less aerodynamic drag and therefore less fuel is needed to propel a car forward.
What do you understand by streamlining?
1 : the path of a particle in a fluid relative to a solid body past which the fluid is moving in smooth flow without turbulence. 2a : a contour designed to minimize resistance to motion through a fluid (such as air) b : a smooth or flowing line designed as if for decreasing air resistance. streamline.
How does the parachute at the back of the car help the speeding car to slow down and stop quickly?
After racing down the pavement for 14 mile, a parachute is deployed to help slow down the speeding car. ... When the parachute is deployed the velocity of the car is quickly reduced due to the increased drag force on the car that is provided by the open parachute.
Why does a ship have streamlined shape?
The aeroplanes and ships have streamlined shaped bodies to reduce drag. The streamlined shaped body experiences minimum resistance when travelling through water or air. It helps to reduce friction.
What could be done to a car to make it more efficient?
Keeping a car's oil filled at the proper level, doing on time oil changes and engine tuning, and ensuring properly inflated tires, all significantly improve fuel economy. Driving behaviors also impact fuel economy.
Why a more streamlined car generally will have better fuel economy than a bulkier car that has the same mass?
So the smaller, lighter car should use less energy both accelerating and moving at constant velocity. A streamlined design would help would improve fuel economy, since the engine would have to do less work to move the car if there was a smaller air-resistance force.
What was the first streamlined car?
Production vehicles
Many production automobiles have had streamlined bodies. Among these were, chronologically by first production year: Pontiac Economy Eight Series 601 (1933) Tatra 77 (1934), claimed to be the first truly serial-produced aerodynamic automobile.
Why must one drive slowly on a wet road?
You must drive as slowly as possible during the wet weather. This helps avoid hydroplaning, skids etc. The most dangerous time is when the rain starts as it causes the oils on the roadway to come up to the surface.
What car has the least drag?
You may not think an entry-level luxury sedan could claim the title of the most aerodynamic car. But according to Mercedes, the new A-Class sedan features the lowest drag of any production vehicle in the world, with a coefficient of 0.22. At this level, it defends the world record held by the Mercedes-Benz CLA.
What car has the lowest CD?
Mercedes A-Class Sedan: 0.22 Cd
Mercedes-Benz claims the new A-Class Sedan has the lowest drag of any production vehicle worldwide.
