From the BMW i7 release is getting closer and closer, BMW i7 is expected to be released simultaneously with the new BMW 7 Series, and BMW iX and i4, i7 still shares the CLAR platform architecture with the 7 Series, which is inevitably reminiscent, BMW i7 is not a pure electric version of the 7 Series?
In fact, there are still many people paying attention to the dynamics of the BMW i7, yesterday and Tuesday, the BMW i7 has the latest news.
The current state of the BMW i7 is that the prototype is undergoing NVH testing, and engineers are optimizing the noise and vibration of the vehicle in the laboratory. At the end of last year, BMW conducted the last prototype road test of the i7, and the spy photos have been published on the Internet. After the last round of road tests, engineers re-tuned the i7's suspension system. BMW officials said that the best balance between the overall control and comfort of the i7 has been found.
Not only that, the BMW i7 also conducted weather and environmental tests to observe the operation performance of the battery pack in extreme cold and high temperatures to ensure that the battery life and performance in extreme weather environments will not have a significant impact. In order to maximize the prototype, the engineers also drove up the hill and pulled a trailer full of goods behind it. To test the BMW i7 energy management system, engineers tested the vehicle downhill after it was fully charged. We all know that the energy recovery system will charge the battery pack during the downhill process of the vehicle, and the responsibility of the energy management system is to prevent energy recovery in the event of full power to avoid overloading the battery pack.
The new BMW i7 pure tram is based on the evolution of the current 7 Series CLAR platform, many people say, is this oil to electricity? Not to mention, the CLAR platform itself supports the expansion of pure electric powertrains. At the same time, the BMW i7 will use the same fifth-generation electric powertrain technology as the i4 and iX.
It is expected that the new car will be equipped with a battery pack with a capacity of up to 120 kWh and will have a full electric mileage of more than 640 kilometers. IN ADDITION TO THE NINGDE ERA, BMW BATTERY PACK SUPPLIERS ALSO HAVE SAMSUNG'SDI AND NORTHVOLT. The BMW i7 is equipped with a modular drive unit that integrates the motor, drive and power control systems. For example, on the BMW iX xDrive50, there are two such units, distributed in the front and rear axles, with a maximum power of up to 523 horsepower. At the same time, BMW also introduced a more powerful version of the iX M60, which has a maximum power of more than 600 horsepower. It is believed that this power system will also be used in the i7.
In terms of charging, the new car will support up to 200 kilowatts of charging power, charging 10% to 80% of the power in just over 30 minutes. For some hurried drivers, under the ultra-high charging power, more than 140 kilometers of cruising range can be obtained in 10 minutes.
The BMW i7 will be equipped with a new energy recovery system, and like the iX, the BMW i7 will also support an adjustable energy recovery mode, with the strongest mode achieving a single-pedal mode.
The BMW i7 is expected to debut before the end of this year, and it is expected that the new BMW 7 Series will also be released at the same time.
