An enthusiast of Nissan Qashqai petrol for sale should know that all-wheel-drive cars are increasingly common, but all-wheel-drive systems are not all the same. Sometimes, not knowing the difference between one and the other can lead to misuse of the vehicle. In the latter case, your wallet will pay the price. There is no doubt that some European, American and Japanese brands are inextricably linked to the subject. Audi, AMC, Toyota, Subaru, Nissan, GM and Ford certainly know the problem very well.
The Drive Torque
The distribution of the drive torque on four wheels instead of two allows, all the other parameters being equal, to have greater traction. Here, a driver can only pay attention to the tires. The grip that each wheel can guarantee depends on many sizes, but it is clear that, apart from the individual performance values, adding two active wheels to the traction system means, in broad terms, halve the effort that each tire has to withstand. The speech made so far is very crude but serves to give an idea of the philosophy behind the concept of four-wheel drive. But, as anticipated, the integral tractions are not all the same. Two very similar abbreviations that however refer to two very different systems. The 4WD traction is typically used on some commercial vehicles, on some American SUVs and almost all the pickups. This is a system that includes a transfer box with at least a reduction in the ratio for the generation of the famously reduced gears.
A Central Differential
The 4WD system, however, is not equipped with a central differential and for this reason, a part-time system is defined. Using a vehicle with 4WD traction on paved road, in perfect grip conditions and the presence of curved trajectories is a serious mistake. The lack of the central differential would constantly impose the same speed between the front and rear axles, which obviously cannot be less than driving on a perfectly straight trajectory with the road free of any depression. The ideal situation that occurs a few times. The AWD system, on the other hand, always has a central torque divider. This means that an all-wheel-drive can work in any driving condition. Typically, it is a system used on the latest generation cars, crossovers and SUVs. AWD systems have the great advantage of not requiring the intervention of the driver; hence, in used vehicles such as in the case of Nissan Qashqai petrol price, a used car buyer should not only heed the discussion but also the functionality of all installed systems.
Without Slip Control
The operation is fully automatic and, depending on the grip conditions, they independently manage torque transfers to the individual wheels or between one axle and another. They have the disadvantage of being very complicated, and therefore very expensive, and in cases where the two axles are permanently connected to the engine, they also have the great disadvantage of raising the vehicle's fuel consumption due to greater mechanical losses. There are modern ones that are capable of operating just one axle and which, if necessary, require the insertion of the other pair of wheels. It is more than evident that a central differential without slip control does not bring great benefits if not the only possibility to always travel with all driving wheels.
