A similar drive configuration is also available on the ModelX, which is also equipped with two drive systems in tandem.
The dual-motor-driven model brings a dazzling effect, the most important of which are two points:
1 Acceleration time becomes shorter: Take P85D as an example, the acceleration of 100 km is 3.2s, and the P85 of single motor requires 4s.
2 The cruising range is longer: 85D is 30 miles longer than 85: from 265 miles (EPA) to 295 miles.
In addition, the dual motor also brings better steering feel and small motor weight. But the other two problems that Xiaobian is more curious:
1 Why do dual motor systems have these advantages? What is its technical solution?
There are many configurations for 2 dual motors. Why does Tesla choose this configuration?
Advantage analysis of Tesla double motor
Why do dual motors have a power advantage, and most people subconsciously react: "The addition of a motor is more powerful, and of course the acceleration is stronger, just like the CPU turns from a single core to a dual core." This understanding really makes the problem simple. If it is only the pursuit of greater power, then why not make the original motor bigger? It is simple and convenient. There must be a mystery, Tesla CTO JBStraubel, two concepts in the "Tesla all-wheel drive (dual motor) power and torque specifications", the first is the battery and motor power matching, the second One is the effective distribution of the torque of the two motors. Maybe it is the mystery.
