Most effective weight reduction in modern cars?

A general rule of thumb is for every 10 percent reduction in weight has a comparable 10 percent reduction in the force required to accelerate or decelerate an object. The same applies for an automobile. To break it down in quarter-mile drag racing, every 100 lb removed from a vehicle equals [approx.]

How effective is weight reduction in car?

A general rule of thumb is for every 10 percent reduction in weight has a comparable 10 percent reduction in the force required to accelerate or decelerate an object. The same applies for an automobile. To break it down in quarter-mile drag racing, every 100 lb removed from a vehicle equals [approx.]

Why is weight reduction important in modern vehicles?

A lighter car consumes less fuel because it needs to overcome less inertia, reducing the power required to move the vehicle. Losing weight is the easiest way to increase fuel economy; reducing a car’s weight by just 10% can boost its mileage by almost 6 to 8 percent.

What is the best weight distribution for a drag car?

Typical values for front-engine, rear-drive cars are 55-51 percent front/ 45-49 percent rear.

Does weight reduction increase speed?

Increased Performance

If you like to race, car weight reduction can increase your speed. You’ll be able to handle tight corners like a champ. Those who want to take it to the next level can make it ultralight with extra subtractions. You can take out the sound insulating materials and even put on lighter wheels.

How do I make my car weigh less?

  1. Remove or swap heavy electrical components.
  2. Fit lighter body panels.
  3. Replace glass windows with polycarbonate.
  4. Lighter wheels.
  5. Put less fuel in your tank.
  6. Lose bodyweight/friends. Image source: Magnus D on Flickr.

    Why are lighter cars better?

    Lightweighting Automobiles Results in Better Fuel Economy

    Thus, lighter cars have a better fuel economy. In fact, for every 10% in weight reduction, fuel economy can be increased from 6 to 8%. This is especially important to hybrid and electric vehicles, as batteries are particularly heavy.

    What is the lightest material for a car?

    LIGHTWEIGHT MATERIALS PROJECTS

    LIGHTWEIGHT MATERIAL MASS REDUCTION
    Magnesium 30-70%
    Carbon fiber composites 50-70%
    Aluminum and Al matrix composites 30-60%
    Titanium 40-55%

    What is magnesium used for in cars?

    Magnesium usage on the front end of a vehicle provides not just a lower overall mass for the car, but also allows for the shifting of the center of gravity towards the rear of the car improving handling and turning capabilities.

    How much horsepower do you lose per pound?

    Roughly every 100 pounds equals about a . 1 second in the quarter mile. I think about 20 HP or so gets you about . 1 second in the quarter.

    Does weight reduction add horsepower?

    Weight to power is one way to get a general idea of acceleration performance. For example, if I have a 3500 lb car with 215 horsepower, I simply divide 3500 by 215 to get a weight to power ratio of 16.28 lbs per horsepower. The same car with 250 hp would have a weight to power ratio of 14 lbs per horsepower.

    How much does weight affect 0 60?

    In general, for a car that weighs about 3000 pounds, you need 10 HP to lower the 1/4 mile time by 0.1 seconds. To achieve the same effect, you need a weight reduction of about 100 pounds. But, if you reduce unsprung mass (wheels, tires, rotors, calipers etc.), the effect is magnified by a factor of 6 or 7.

    Do lighter wheels give better mpg?

    According to testing by TireRack.com, a combined 3 lb reduction per corner (wheel and tire) improved freeway MPG by 5%. Even bigger savings are generated with city driving as wheel weight is crucial during frequent acceleration and deceleration.

    Do lighter wheels improve ride quality?

    It appears that lower unsprung mass (like lighter wheels) results in a less bumpy ride over poor roads. However, the downside is that it could increase the “fine vibrations” that you feel over some “relatively smooth surfaces” such as concrete roads or an asphalt road with gravels.

    How much slower is a full car?

    There is also really no such thing as a definitive 0-60 MPH time. The results depends on so many variables. A good baseline assumption is that the elevation accounts for a roughly 15% decrease in power across most vehicles. Of course, things like forced induction come into play here, but 15% is a good rule of thumb.

    Do engines get slower over time?

    Almost any car with close to 200K miles on it is going to have lost some performance. Engine deposits, mechanical wear, leaky seals, faulty/failing sensors — all these things accumulate over time. As you say, they can all be fixed, but there will be performance loss.

    Do Motors get slower over time?

    Yes. Brushless, electric motors do lose power over time.
