What do these things do for a car?

Question

Rides height and areodynamics anyone knows plz let me know thanks.

Answer 1

Ride height determines the center of gravity, and likelihood to roll in a collision. The higher the more likely, as in an SUV. Aerodynamics is the movement of air around the vehicle as it moves. Is it smooth, leading to good mileage, or turbulent, unsmooth, causing drag and wasting gasoline? This is tested in a windtunnel with smoke, so that the flow can be seen. Little threads can also be attached all over the body. If they flutter, the flow is not smooth in that spot.

Answer 2

Aerodynamics largely = resistance offered by the car body to air passing it. Good aerodynamics mean it can travel easily and efficiently at high speeds, bad ones turn it into a thrown brick that needs a lot of power (and fuel!) to get up to speed.
e.g. Old VW Polo, 45hp - would do about 90mph flat out in standard form (itself a brick, but with some nods to smoothness). With a lightweight but very blocky roof-rack added, carrying some bulky items (less than 50kg!), it felt the same around town, but struggled to reach 75mph - also using about as much fuel as it would at the higher speed! Extreme example but hopefully it illustrates what I mean. The turbulence caused by large objects pushing through air (and the sheer force required to push such volumes of air out of the way!) causes ever increasing drag as your speed rises.

Also as others have said, it can have implications for your roadholding. However, typical measures to increase "downforce" at high speed are actually side effects of what might otherwise be called bad aerodynamic elements; the energy used to "push" the car against the road against the lift caused by the rest of it's bodyshape is sapped from that used to accelerate forwards.

Ride height is more of a handling, cornering, and more often than not, a cosmetic issue. Having the car lower down, besides what has already been mentioned, means the suspension has much less travel, and so rolls less in fast corners and is able to keep all four wheels on the ground more effectively. However, this must be balanced with a harsher ride (apparent to the occupants) and a tendancy for the car to "skitter" and skid even worse than before should you overdo it - some suspension travel is necessary to smooth out the road bumps and keep the rubber in contact!
Also, a dropped car, particularly one that's been "decked" (very little air space between the bodywork and ground, suspension being reduced to the practical minimum - so much so the chassis will often scrape and spark on rough surfaces) looks so much meaner and sportier than one with standard moon-buggy ride height :-)

Answer 3

Well both height and aerodynamics would be a big factor in the handling of the car while driving. A lower car will handle better in cornering, assuming it is factory designed. When you lower a car on your own, the ride will be very bad and you usually lose the handling. Aerodynamics determines how fuel efficient a car will be. The less drag while driving will allow a car to move through the air easier.

Answer 4

hay this is a good one
i had a vw bug that i turned into a baja and lifted it up for ground clearance
than souped it to a hot rod we went to a Long strait road to see how fast it would go the shape of the car is a airplane wing kind of and with the extra lift air was able to get under it and it came air-born at approx 93 miles an hour for about 13 seconds we traveled approx 1500 feet that's further than the write brothers did on there first flight
if we would have lowered the front end this wouldn't of happened
that is why they stream line and do the height thing its to keep you on the road where you belong

Answer 5

The lower the vehicle the less air that can pass beneath. This will help to keep the vehicle from lifting off the ground at higher speeds.

Answer 6

This question has been answered better by others than I am willing to give the time too.
