E-cars move faster than combustion engines - but why? Of course, the torque is immediately available, but there are more reasons.
Even electric cars that are not decidedly sporty vehicles are surprisingly powerful. This has always been a driving fun argument for convinced electromobilists. But why are e-cars actually so good at it? Is it just the immediately available torque? No, there are several reasons for this (see video). A small selection.
The power density
Because electric motors with their high power density take up less space than comparably powerful combustion engines, the engineers have more leeway when designing or selecting a suitable e-machine. There is a tendency for more powerful engines to find space in cars. Incidentally, the advantage in terms of power density for the electric motor is around a factor of 30 compared to the combustion engine. ,
The rotational capacity
Electric motors deliver their power over a wide speed range. Some machines rotate up to 19,000 rpm and the maximum torque often extends over a wide range. With an electric drive, you usually save on the gearbox and clutch. The latter is usually subjected to a great deal of stress when accelerating and costs time in the slipping phase, in which the full force is not acting on the wheels. The same applies to interruptions in traction during shift breaks - all of which can be neglected in electric cars.
Control systems and the driver factor
In addition to the two points mentioned, there are a few more that give the electric car an acceleration advantage. These include faster control systems and the driver factor, which easily becomes a time waster in combustion engines. We give you these and other explanations in detail in our video at the top of the article. ,
Conclusion
Electric cars usually make the combustion engines look old in the sprint. There are several reasons for this. In addition to the well-known advantage of the immediately available torque, the Stromer benefit from their general turning capacity and their power density. In addition, the driver in the e-car has it easier and does not become a time waster when accelerating.
