For example, Toyota Prius weighs 1405 kg, and Toyota Corolla, similar in consumer characteristics, weighs 1240 kg. The hybrid engine must not only pull the car, but also a heavy attachment in the form of an electric motor of 50 kilograms and a battery of 100 kilograms. As a result, fuel consumption under real operating conditions on long-distance trips is almost the same for both cars – 7-8 liters.
Overheating and underheating
Despite the specified position of 300,000 km, the hybrid installation is very fickle. The electric motor is usually located in the gearbox, which means the transmission runs at much higher thermal loads, meaning hybrids require special oil and service intervals are cut in half.
The inverter controls the power plant, which also gets very hot and needs additional heat dissipation. Otherwise, electronic circuit boards, which cost several thousand dollars, will burn through. The battery also needs cooling in summer and heating in cold weather. As a result, the Prius and the Lexus RX400h already have two cooling systems, which tend to break down and get dirty.
But the main problem, of course, remains the battery life, which rarely exceeds 8-10 years, after which the entire battery plate gradually turns into ballast. And the new one costs just like the battleship Bismarck.
