In practice sometimes the power is discharged more on the front, sometimes on the rear that, while on one hand ensures more tightly, it has as a downside a greater unpredictability with behavior of the vehicle sometimes understeering, other times oversteering as shown in Reasonable Suspicion Training.
A further advantage given by all-wheel drive cars is being braked as we will use the engine brake on all four wheels with indisputable advantages in reducing braking distances, especially when driving at the limit.
The advantage over slippery surfaces is undeniable, as mentioned above. Especially on snow we can realize the usefulness of 4-wheel drive; be careful, however, not to get too caught up. Adherence is always a function of many factors, among which the most important is certainly the type of tires fitted and their way of working on the asphalt; on certain occasions it will also be useful on 4×4 to assemble the chains: in this case we can choose the axis on which to install them. However, it is preferable to mount them on the front axle, especially to improve the vehicle’s steering capacity.
Remember also that being able to have a better grip means being able to have a safety reserve to be used in emergency conditions: if we always drive to the limit this reserve could become nothing with unpleasant consequences, and this applies to any security system yet those who manage to go beyond the laws of physics have not been invented.
Batteries made with different technologies, designed for certain types of vehicles and certain conditions of use. You can’t tell which batteries are better and which ones are worse, they all have Reasonable Suspicion Training advantages.
Football batteries have excellent current characteristics, but are demanding on the quality of the car’s electrical equipment. Almost do not boil, self-discharge is reduced to a minimum, but have a greater cost.
Low Aging batteries They do not have such high currents, but are less demanding on the work of the machine’s electrical equipment. These batteries require more attention to themselves, but are distinguished by their high resistance: they are not very sensitive to falls in the onboard voltage and are resistant to deep discharges.
Hybrids occupy an intermediate position, combining the advantages of both technologies: high starting currents and low water consumption of calcium batteries and low anti-aging resistance. Can I install a battery with a capacity greater than that recommended by the car manufacturer? It is possible, for example, that additional electrical equipment is installed or that the car is used in extremely low temperature conditions. The battery should adapt to the size.
Can I install batteries of different brands or a new and old battery on a truck? No, since these batteries have a different internal resistance and behave differently when receiving and receiving electrical charges. This could cause an electric car trouble and improper work.
