- The Difference Between Front and Rear-Wheel Drive
Vehicle acceleration on a flat road is possible thanks to two systems: powertrain and driveline drivetrain.
A Drivetrain is a system which connects the transmission of a car to its driven axle. In simpler words, drivetrain involves all the systems and equipment which take power and torque produced by the engine, from the transmission to the driven wheels. A RWD system requires the engine and gearbox to be longitudinally mounted so that the drive can be sent straight to the differential at the rear.
A RWD car will have the slight disadvantage of having lesser space inside the car, as the driveshaft will have to go underneath the body, which is why some cars have the bump in their floor. But RWD cars have always pleased automotive enthusiasts, as according to them, they are more 'fun' to drive. Sliding the rear-end of the car out and having fun is something that began with RWD cars. It took decades to develop FWD because of the complexity it involves.
The front wheels have to both drive and steer the car, which is exactly what makes it complex. Though many engine configurations were tried, it was found that the engine had to be mounted transversely to get the gearbox and differential to fit in the same space. The decades spent on developing FWD seems worth it when looked at from the 21st-century perspective. Most of the cars on the roads today are FWD. All the hatchbacks, and almost all sedans today are driven by their front wheels.
FWD is more efficient than RWD, and it also saves some space inside the car as it does not require a driveshaft under the body. However, most FWD cars have understeer as its natural character in which the front end of the car goes out when a corner is taken too fast. Four-Wheel-Drive 4WD : 4WD vehicles are those vehicles with drive going to both the axles, in turn, transferring torque to four wheel ends.
It is optimized for off-road driving conditions. The roots of 4WD systems can be traced back to when English engineer Bramah Joseph Diplock patented a Four-Wheel-Drive system and built a vehicle that displayed an ability to travel on challenging terrain. Well, the purpose of 4WD systems have stuck to the same roots ever since, as they are until this day, used to travel on tough terrain, sometimes for a purpose, and sometimes for pleasure.
It is so because the first figure in 4x4 represents the total number of wheels and the second represents the number which is powered. While 4WD is designed to take the vehicle off the road, AWD is designed to keep the vehicle on the road. Quite literally. The application of AWD today is mostly in powerful cars, and in some soft-roaders as well if required to traverse on some rough terrain. On powerful cars, an AWD helps put the power down to the road better, and it handles better which in turn makes it faster and quicker.
AWD systems can detect which wheel needs the most power at the particular moment and which wheel needs none at all. On soft-roaders, it can get the car out of a sticky situation. P 4WD. Since then, the world of rallying has never gone back to the RWD configuration. Today, AWD systems are used on a variety of vehicles. AWD systems and 4WD systems are sometimes offered as optional extras, giving the customers a choice.
Individual Wheel Drive IWD : IWD is the drivetrain used in most electric cars, which are gaining more popularity as we are heading towards an electric car-driven world. It works exactly as the name suggests since it is driven by electric motors which are placed at each wheel end, driving that wheel alone.
IWD has many advantages and almost no disadvantages. Being placed at the axle ends, all it requires is the power cables to reach the electric motors. Individual-wheel-drive also allows flexibility in the way power is sent to the wheels, and the car's management systems can detect and send power only to those wheels which have the maximum traction without the involvement of any complex mechanical bits. H-Drive: A H-Drive drivetrain layout is not very well known, as it has seen only military use, and even among military vehicles, it is a rare drivetrain system.
It features individual wheel stations instead of axles. The gearbox is connected directly to a single differential which splits the drive into separate left and right drives. The left and right drives are further split by another set of differentials to the front and rear wheels.
At each wheel station, there is a bevel box which drives the half-shaft out to the wheel. This system is used on some heavy off-road vehicles which use 6x6 or 8x8 configurations.
This system allows every wheel station to have individual suspension, in turn giving the tyres more traction. There is increased ground clearance as well because there is no axle and differential or even the central driveshaft. DriveSpark Thinks! Going by the current happenings in the Automotive Industry, it does seem like Individual Wheel Drive is the way forward.
It is very obvious that electric cars are the future, and having motors on the four wheels of a car will make things very flexible for the driver, irrespective of the type of vehicle. Depending on the terrain, load and also the type of vehicle, the computers aboard the cars can decide to send power to individual wheels, making the vehicle a FWD or RWD or AWD, maybe even 4WD, as and when required, all within a few moments.

Types of four-wheel drive (4WD) and all-wheel drive (AWD) systems
Sep 11, Blog , Colorado Automotive Advice. We come across a lot of questions here at AAMCO Colorado, and one that continues to be raised is what the differences are between front and rear-wheel drive vehicles. Most people have probably driven a rear-wheel drive vehicle before, which is essentially when the power from the engine is transferred to the rear wheels of a vehicle via the drive shaft. Rear-wheel drive is used for vehicles when there is either a sporting purpose or off-road capabilities are needed. RWD offers a few benefits that front-wheel drive cannot, mainly, it provides better acceleration, handling, and weight distribution. Better acceleration can be expected from RWD vehicles because the weight shifting and distribution forces the rear tires to dig more into the ground, thus gaining more traction from the tires.
What about the differences between all-wheel drive and four-wheel drive? The majority of vehicles on the road today are powered by front-wheel drive systems. In this system, the front wheels provide the power. All of the drivetrain components are located in the front of the vehicle which increases traction in the front wheels. Vehicles with front-wheel drive are typically lighter, helping to improve gas mileage. Once the industry standard, a rear-wheel drive system relies on the rear wheels to deliver the power.
A Drivetrain is a system which connects the transmission of a car to its driven axle. In simpler words, drivetrain involves all the systems and equipment which take power and torque produced by the engine, from the transmission to the driven wheels.

The Difference Between Front and Rear-Wheel Drive
There is no such thing as a no-wheel drive car, except for maybe the foot-powered one Fred Flintstone drove. Rear-wheel drive is the opposite; the engine spins the rear wheels. Four- and all-wheel drive cars have power at all four corners. Each layout comes with its own set of pros and cons that affect the way the car drives in a variety of conditions. Rear-wheel drive, often abbreviated as RWD, is the oldest layout.
Show all documents Everywhere on earth, people come into contact with these vehicles, often on a daily basis. Typically, a vehicle is one of the most complex and sophisticated products of the industrial revolution that individuals encounter and which they must interact.

Simply put, a drivetrain is the series of parts in your car that work together to make your wheels turn. A powertrain , on the other hand, is basically a drivetrain plus the engine and some other parts. While some praise the advantages of four-wheel drive and all-wheel drive, most cars are two-wheel drive 2WD , in which power is either transferred to the two front wheels front-wheel drive or the two back wheels rear-wheel drive. In nearly all cases, however, 2WD gets the job done.
Мозг лихорадочно искал какое-то другое объяснение, но не находил. Перед ее глазами было внезапно появившееся доказательство: Танкадо использовал меняющуюся последовательность для создания функции меняющегося открытого текста, а Хейл вступил с ним в сговор с целью свалить Агентство национальной безопасности. - Это н-не… - заикаясь, произнесла она вслух, - невероятно. И, словно возражая ей, в ее мозгу эхом прозвучали слова Хейла, сказанные чуть раньше: Танкадо не раз мне писал… Стратмор сильно рисковал, взяв меня в АНБ… Рано или поздно я отсюда слиняю.
Экран монитора был погашен, но она понимала, что он не заперт: по краям экрана было видно свечение. Криптографы редко запирали свои компьютеры, разве что покидая Третий узел на ночь. Обычно они лишь уменьшали их яркость; кодекс чести гарантировал, что никто в их отсутствие к терминалу не прикоснется.
