Nelivetoisan

Nelivetoisan is a Finnish term that translates to "all-wheel drive" in English. It refers to a drivetrain system in a vehicle that powers all four wheels simultaneously, either permanently or on demand. This contrasts with two-wheel drive systems, where power is sent only to the front or rear wheels.

The primary advantage of nelivetoisan is improved traction. By distributing power to all wheels, the vehicle is better equipped to handle slippery surfaces such as snow, ice, mud, or gravel. This enhanced grip can lead to greater stability and control, particularly in adverse weather conditions or off-road situations.

There are several types of nelivetoisan systems. Permanent all-wheel drive sends power to all four wheels at all times, though the distribution might vary between axles. On-demand systems, also known as selectable or automatic all-wheel drive, typically operate in two-wheel drive mode for normal driving and engage the additional driven wheels only when slippage is detected. Some advanced systems can actively distribute torque between individual wheels to further optimize traction and handling.

While nelivetoisan offers significant benefits in terms of traction and capability, it can also come with drawbacks. Vehicles equipped with all-wheel drive often have slightly higher fuel consumption due to the increased mechanical complexity and weight. Maintenance costs can also be higher, and in some cases, the all-wheel drive system can add to the initial purchase price of the vehicle.
