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.

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.

Vehicle Layout

In fact, all but a handful of SUVs are primarily front-wheel drive vehicles, with additional components that send some power to the rear wheels as the need arises. Front-wheel drive designs are cheaper to manufacture and more space-efficient than rear-drive systems. From a packaging standpoint, front-drive also precludes the need for a space-robbing driveline hump running down the middle of the cabin floor. Rear-wheel drive RWD is commonly found on pickups and old-school truck-based SUVs, along with sports cars and high-performance and luxury sedans. For trucks, RWD allows the use of bulky, heavy-duty components, and it provides better traction with a hefty load.

Vehicle acceleration on a flat road is possible thanks to two systems: powertrain and driveline drivetrain. The powertrain is the system which generates power torque and speed. The driveline is the sum of mechanical components placed between the wheels and the powertrain. All the components after the engine, which transmit the power to the wheels, are part of the driveline. The driveline has multiple roles:. Depending on which axle contains the drive wheels, we can have:. Front-wheel drive FWD vehicles contain both the engine and the drive wheels on the front axle.

The Difference Between Front and Rear-Wheel Drive

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.

Drivetrain Systems Explained: Difference Between FWD, RWD, AWD and 4WD

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.

Simply put, a drivetrain is the series of parts in your car that work together to make your wheels turn.

What is rear-wheel drive (RWD)?

Published on Dec 29, According to the Mantrans professionals, both the automobile technologies grew up on their own path and have distinct advantages. Hence, it is difficult to answer which of the transmission is better.

Но более страшным стало то, что он увидел в следующее мгновение. Скрытые тенью, на него смотрели глаза Грега Хейла, глаза, полные ужаса. Тогда Стратмор понял, что Грег Хейл должен умереть. В ТРАНСТЕКСТЕ послышался треск, и Стратмор приступил к решению стоявшей перед ним задачи - вырубить электричество. Рубильник был расположен за фреоновыми насосами слева от тела Чатрукьяна, и Стратмор сразу же его. Ему нужно было повернуть рубильник, и тогда отключилось бы электропитание, еще остававшееся в шифровалке. Потом, всего через несколько секунд, он должен был включить основные генераторы, и сразу же восстановились бы все функции дверных электронных замков, заработали фреоновые охладители и ТРАНСТЕКСТ оказался бы в полной безопасности.

А перед глазами у нее стоял образ Фила Чатрукьяна, его искалеченного и обгоревшего тела, распростертого на генераторах, а из головы не выходила мысль о Хейле, притаившемся в лабиринтах шифровалки. Правда открылась со всей очевидностью: Хейл столкнул Чатрукьяна. Нетвердой походкой Сьюзан подошла к главному выходу- двери, через которую она вошла сюда несколько часов. Отчаянное нажатие на кнопки неосвещенной панели ничего не дало: массивная дверь не поддалась. Они в ловушке, шифровалка превратилась в узилище. Купол здания, похожий на спутник, находился в ста девяти ярдах от основного здания АНБ, и попасть туда можно было только через главный вход. Поскольку в шифровалке имелось автономное энергоснабжение, на главный распределительный щит, наверное, даже не поступил сигнал, что здесь произошла авария.
