Sport Utility Vehicle (SUV) as a Climate Killer

By far the most unnecessary car model is now also widely available electric. No matter which engine, hardly anyone needs something like this. From an energetic point of view, it is a disaster. High weight and poor aerodynamics cause energy consumption to skyrocket.

It’s shocking that more than one in three newly bought cars worldwide is already an SUV and this has consequences. Studies show that if this trend does not subside by 2040, the CO2 savings of approximately 150 million electric cars will be nullified. The reason: an SUV consumes on average around a quarter more fuel or energy than a medium-sized normal car.

Electric SUVs
The problem with cars that are already heavy is that they need very large and heavy batteries to achieve the usual driving performance and acceptable range as a pure electric variant. Electric SUVs are locally emission-free, but the high energy consumption does make it unreasonable because it is not only green energy that is being fuelled. Even if it is green energy, it can be better used elsewhere.

The problem with aerodynamics and weight
From a speed of about 60 km/h, aerodynamics is the decisive factor because the air resistance then exceeds the rolling resistance. That is why sports cars have a streamlined shape, because the higher the speed, the greater the influence. Aerodynamics does not have a major impact on city traffic, but the problem there is the high weight of the car, which has to be accelerated and braked constantly and thus consumes an unnecessarily large amount of energy. Physics shows that clearly.

The problem in cities
The growing number of SUVs is also a problem for cities. Due to their size, they take up much more valuable public space than other modes of transport and parking is increasingly becoming a problem.

Accident risk
The risk of being seriously or fatally injured in an accident with an SUV is four times higher for drivers of smaller cars. In the event of a collision with a small car, which often weighs only half the weight, the lighter vehicle absorbs most of the energy of the collision. The risk of injury to pedestrians and cyclists is also higher due to the size and the height of the front. The person hit can barely roll over the hood and the accidents are therefore usually more severe.

Conclusion
Design, comfort, and a high seating position seem to be more important to many car buyers today than the lowest possible consumption, a streamlined body shape, and low weight. Unfortunately, even manufacturers rarely advertise these properties, unless at sports cars. Wide, chunky, and heavy cars are a step backward in vehicle development. Additionally, they also cost you a lot of money.

Would you still buy an SUV now?

  1. […] The problem is even likely to grow: Because of the SUV boom, cars are tending to become heavier, and most electric vehicles weigh more than comparable combustion engines because of their batteries. And the heavier a car, the greater its tire wear. An additional contribution to the SUV problem if there is more detailed interest: Sport Utility Vehicle (SUV).

  2. […] No other body shape has such a high proportion of private customers as SUVs. Especially old people who often want to buy new cars get in comfortably, sit high, and enjoy plenty of arm and headroom. Sedans and station wagons, on the other hand, can only hold their market share as company cars.
