Why does a crossover engine break down faster than a passenger car?

Crossovers and cars are often equipped with the same powertrains. At the same time, their resource on an SUV is often much less than on cars. About why this happens, says the portal "AvtoVzglyad".

The same engines are now put on many cars. For example, the Hyundai Solaris sedan and the Creta crossover are quite different in weight, while they have one 1,6-liter engine with the G4FG index. The unit of the same volume is installed on Renault Duster and Logan. We are sure that they will last longer on light sedans, and here's why.

The crossover has worse aerodynamics, which is further worsened by high ground clearance. And the greater the resistance to movement, the more power you need to expend in order to accelerate to a certain speed. Well, the more power, the greater the load on the engine. Consequently, the wear of the unit also increases.

But that's not all. Crossovers often "dip" in the mud and crawl in a deep rut. Much more often they slip. And this imposes an additional load on both the engine and the gearbox and transmission parts. Accordingly, during an off-road assault, the airflow of the power unit worsens. All this also leads to a reduction in the resource of the engine and transmission.

Let's not forget about the "mud rubber" that tuning apologists love to put on. The difficulty here is that improperly selected tires not only add stress to the motor and gearbox, but because of them, the wheel drives can turn in the mud. If we talk about passenger cars, then such “shoes” simply cannot be found on them. And with road tires there will be no such problems.

Under the off-road "fun", many owners also install emergency protection of the engine compartment, thereby disrupting heat transfer in the engine compartment. From this, the oil in the engine wears out, which also affects the life of the motor.

Finally, the engine that sits on the crossover has to rotate a rather complex transmission. Say, on an all-wheel drive SUV, you need to turn the cardan shaft, bevel gear, rear axle gear, rear wheel coupling and drives with CV joints. Such an additional load also affects the resource and makes itself felt over time.
