advantages of porcelain dinnerware fwd vs. rwd. which is better? - free article courtesy of ...
There is an endless debate on the entire Internet car Forum.
Which is better;
Front wheel drive (FWD) or rear wheel drive (RWD )?
Let's look at each one.
Starting at about 1920, the front wheel drive didn't catch up with American consumers until the 1970 gas crisis.
As the American people struggle with high oil prices, automakers are looking for new ways to improve fuel efficiency.
Of course, the best way is to reduce the size of most vehicles (thus reducing the weight ).
Since Detroit's goal is to make cars smaller, they need a more efficient layout to provide more interior space in a smaller package.
The solution is the front wheel drive.
By placing the engine and the Trans-shaft in front, there is no large transmission housing or drive tunnel through the passenger compartment.
In addition, in order to reduce the size of the engine compartment, the engine is placed horizontally.
There is another advantage.
The weight of the Fwd is 60% in the front, 40% in the back, and in smooth conditions, such as ice or snow, the fwd has an advantage because more weight exceeds the drive wheel, thus
But most of the advantages are there.
The balance of the fwd car is not very good due to most of the weight in front, so its handling is not very good either.
In addition, the front wheel drive becomes more and more important as the vehicle becomes more and more powerful.
Torque steering (pulling to one side when the steering wheel is accelerating) is a serious problem for many front wheel drive cars that exceed 250hp.
As a result, we have seen the rear wheel drive re-pop in more powerful vehicles.
The rear wheel drive was King before the 1970 fuel crisis.
From economy to luxury, almost every car has a rear wheel drive.
Turning from rear wheel drive to front wheel takes about ten years.
Starting from the post-80 s, almost every economy sedan, family sedan, minivan, and even many sports cars have front wheel drives.
Luxury signs such as BMW and Mercedes-
Mercedes continued to drive the rear wheels, but Cadillac eventually moved every car to the front wheel.
The Times have changed again.
Over the past few years, we have seen more and more vehicles introduce rear wheel drive. Why?
Well, it's convenient.
As cars become more powerful, it is difficult to have a set of wheels for steering and acceleration.
You will get better by having the front wheel do steering and the rear wheel drive the car --
Balance the vehicle.
This eliminates torque steering and increases acceleration.
The rear wheel drive provides a better weight distribution (closer to 50/50 than the fwd), which in turn provides a more predictable handling.
Finally, with the emergence of the traction control and stability management system, the advantages of the front wheel drive in wet slip conditions are significantly reduced.
More and more rwd vehicles can also choose AWD.
If nothing else, this is a good way for automakers to hedge bets.
Still, some consumers are skeptical about rear-wheel drive.
Maybe they are the victims of clever marketing on Madison Avenue.
Try to get people to accept fwd and forget all the advantages of rear wheel drive.
They did a good job.
Maybe too good.
Cars are more powerful today, but fuel economy is better.
So we can look at fwd and rwd more objectively.
Is one better than the other?
Fwd still has an advantage in packaging efficiency, providing greater interior space in smaller packages.
The rear wheel drive provides better handling and acceleration, coupled with traction control, virtually eliminating the fwd advantage in snow.
Finally, it depends on what you want to get from your car.
If it's a show, you're looking at rwd.
If you're indifferent, maybe looking for a small car with a larger interior size, it's your front wheel drive.
Over the past 20 years, technology has improved both layouts, reducing the fwd advantage to the point where rwd is a viable option for most people.
In the end, you have more choices and we all win when there are more choices.
