Rear wheel drive or front wheel drive? Advantages and disadvantages. Air suspension for Transit (Ford Transit) front-wheel drive List of accessories for connecting pneumatic lines
In this class of trucks there is a tough competitive war, the struggle is for each buyer. Unlike most rivals that produce vehicles with only one type of drive, Ford offers Transit light trucks with non-wheel drive in both front and rear wheel drive. Previously, they were produced in Belgian Ghent, and now - in Turkey. Both versions are called Transit, and approximately 90% of their components are absolutely identical. And the buyer is faced with the question: which one is most suitable for specific purposes?
First of all, you should focus on the total mass. For front-wheel drive vehicles, it usually does not exceed 3.0 tons; rear-wheel drive - heavier, up to 4.25 tons. Where both concepts converge and the carrying capacity of both versions is approximately 1 ton, the buyer has to rack his brains to make a choice.

In this, familiarization with the proposed engines can help him. For those and others, three four-cylinder diesel engines with turbocharging and intercooling of charge air, with direct fuel injection are intended. The difference between them is only in small details. For the front-wheel drive version, the maximum engine power is 100 hp, for the rear-wheel drive version - 125 hp. The difference in torque is also striking. And this is not surprising, since the displacement of the engine installed on the rear-wheel drive car is 2.4 liters, while the two-liter engine is used on the front-wheel drive. Both engines have a modern four-valve design, but the common rail fuel injection system is not used.
In comparative tests, approximately the same conditions were taken care of. The front-wheel drive Transit van with a 100-horsepower engine opposed its rear-wheel drive "colleague" equipped with a 90-horsepower engine. The maximum torque, on the contrary, in the first case is 190 Nm, in the second - 200 Nm. The gearbox is a five-speed manual. It should be noted that the rear-wheel drive Transit with a 66 kW engine is the only Cologne model offered with an automated Durashift gearbox.

| Front-wheel drive |
During the test run, both Transit had the same load - 600 kg each. Already after the first kilometers of run, it became obvious that the seemingly “twins” of the car are distinguished by their individual character. A front-wheel drive car's engine gives it more agility, and the van responds more accurately to steering wheel turns than a rear-wheel drive one. The noise when starting a cold engine is quite strong, but with increasing operating temperature it becomes more restrained. It is sensitive to load changes. Both models have good dynamic qualities.
When comparing the power expended in movement, the front-wheel drive made its way first to the goal in all disciplines. Both the acceleration dynamics and the elasticity of the rear-wheel drive Transit lag behind. At the final speed, it also turned out to be worse. Well, his average fuel consumption was 1 l / 100 km more than that of the front-wheel drive.

The design of the cabins can be estimated the same. The instrument panel remains unrivaled. There are no shortcomings in the management of switches, levers. Gears in the box shift accurately and easily.
Dissimilar "brothers" share weaknesses. When looking at the cargo area, it becomes obvious that the front-wheel drive model is ahead of the competition. The floor in the cargo area is welded deeper by 100 mm, which has benefited the capacity. This is in addition to the fact that bodies are Ford's forte anyway. The almost sheer sidewalls and large side and rear doors of the Transit are useful for carriers. Traction effort deserves the same rating. The front-wheel drive van, both loaded and unladen, feels more nimble and nimble than its competitor.
The strength of the rear-wheel drive Transit is its high tractive effort. It is logical: the greater the load on the rear axle, the better the traction. And as a result, he can take more weight. The weight of the trailer is 2.8 tons, which is clearly more than that of the front-wheel drive. However, there is a downside to this: an empty rear-wheel drive Transit cannot climb high uphill in winter.
And the last. The base price of the front-wheel drive model is clearly lower than the rear-wheel drive model. Those who do not need a large payload can save money by opting for front-wheel drive. The strengths are the numerous options (three bases, five lengths of the load compartment and three roof heights). In addition, Transit comes in three variants by area of use: Transit Express Line (mail delivery), Transit Service Line (workshops) and Transit Fresh Line (for transporting products), as well as a double cab van. Not only the drive, but also a wide model range can contribute to the choice of buyers.

24.06.2014 When purchasing a new car, every driver asks the question: "Which drive is better?". To make a decision and choose the best option for yourself, you should consider the pros and cons of both elements.
For most Russian car owners, rear-wheel drive is more familiar. Let's consider its main advantages. In cars equipped with rear-wheel drive, the load on the axles is evenly distributed, which allows the car to slip less during a sharp start. In addition, vibrations from a running engine are less felt during a trip, which makes the trip more comfortable for both the driver and passengers. If the car skidded, then the skid can be easily detected and eliminated - for this you need to release the gas and turn the steering wheel in the right direction. In a front-wheel drive car, the opposite is true: you need to press the gas pedal so that the rear wheels take the correct position and direction. All these qualities confirm the fact that rear-wheel drive cars are more comfortable and safer.
The disadvantages of rear-wheel drive vehicles include the following: high cost and production; the use of such a drive makes the car heavier, which leads to higher consumption of gasoline and oils; the capacity of the cabin is reduced due to the tunnel in which the cardan shaft is located - it passes in such a way that it divides the body in half; rear wheel drive design is very heavy and bulky. In addition, such a car overcomes sections of the road with mud and snow much worse, which is fraught with unpleasant consequences.
Now consider the advantages of front-wheel drive cars. First of all, this is a relatively inexpensive production price, as well as a more confident overcoming of slippery road sections with snow and mud. Salon can be enlarged due to the absence of a cardan shaft. The disadvantages of this drive are: strongly felt vibrations when the car is moving; starting abruptly, the car tows heavily, which creates some inconvenience for the driver; during acceleration, the steering wheel may also vibrate due to the reactive forces coming from the motor. It should be borne in mind that cars with a power of 180 horsepower or more receive a huge load on the most important parts of the undercarriage, which can lead to difficulty in controlling the machine.
An ordinary driver will not much feel the difference between a rear-wheel drive car and a front-wheel drive car - this difference is felt only in extreme situations, taking into account weather conditions. It is worth adding that when choosing between these two options, it is necessary to take into account the characteristics of the roads on which the car will be operated, as well as your financial capabilities.
