Common questions

Does a spoiler increase acceleration?

Does a spoiler increase acceleration?

At high speeds spoilers impeed acceleration and top speed, but at intermediary speeds they help acceleration.

Does a spoiler increase handling?

At low speeds, a fixed spoiler may actually increase drag, but does little to improve the handling of the vehicle due to having little airflow over it. A retractable front spoiler can reduce scraping of the car on curbs or other road imperfections, while still reducing drag at high speeds.

Does the spoiler on a race car cause air pressure to push the car forward?

The spoiler on the back of a racing car is curved on the lower side, so a spoiler is an upside-down wing. The greater pressure pushing downward on a spoiler gives the car better traction from its rear wheels. As a result, the air moving over the top moves faster and exerts less pressure than the air on the bottom.

What’s the difference between a wing and a spoiler?

Wings work by using an airfoil shape that causes lower pressure underneath it. Spoilers work on the same principle but use the entire car as the “airfoil” and create a low pressure zone and a lot of drag at the back of the car.

What is the purpose of a spoiler on a VW Polo?

Main purpose of spoiler is to generate down force or negative lift. More down force is good but at the same time drag produced must be minimum. It is more important to maximize the down force to drag ratio. The VW Polo car was analyzed for two cases namely with and without spoiler.

Why do you need a rear spoiler on a car?

There is no need to increase in vehicle weight for better handling. Spoilers help in maintaining the traction at very high speed and provide the vehicle stability. Installing the rear spoiler on vehicle not only increase the traction but also increases the braking stability because of the down force generated by it.

What does a rear spoiler do for a car?

Some performance models come with more prominent rear spoilers or wings perched above the trunk, but the spoilers alone doesn’t necessarily make the vehicles more aerodynamic or can go faster. Instead, there is much more about the aerodynamics of a vehicle than simply attaching a wing or rear spoiler in car, as you will find out more below.

What’s the difference between a spoiler and a wing?

Whereas spoilers are all about redirecting airflow away from the region where the spoiler sits. The bulk airflow isn’t even supposed to hit them. More CFD, showing the stagnant pocket (dark blue) in front of a spoiler (rear car) vs a wing (front car): Of course, CFD is only moderately reliable. (Fluid dynamics are hard.)

Where are the spoilers on a NASCAR car?

When you look at NASCAR spoilers, you don’t see a wing or a graceful ramp, you see an air-blocking wall at the tail of the car: This air-blocking flap creates a relatively stagnant pocket of air (shown in green) between the rear window and spoiler:

Are there any spoilers that make a car go faster?

Internet companies selling ridiculous body kits generally aren’t doing a lot of that stuff. Just to make it extra clear what I’m saying here: spoilers that stick up above the roof of the car are blisteringly stupid. They make the car’s slipstream significantly larger and add a ton of drag.
