Here is the requested summary of the YouTube video: - The video tests electric car range under real-world driving conditions. - An updated Porsche Taycan with a 97 kWh battery and a claimed range of 421 miles is being reviewed. - A new Tesla Model 3 Long Range with a 75 kWh battery and a claimed range of 413 miles is also reviewed. - Other cars tested include the BMW i5 M Sport Pro with an 81 kWh battery and claimed range of 362 miles. - Also tested is a BYD Seal Design with an 82.5 kWh battery and a claimed range of 354 miles. - A Polestar 2 Long Range Single Motor with a 79 kWh battery and a claimed range of 406 miles is reviewed too. - The Mercedes EQE 300 Sport Edition with an 89 kWh battery and claimed range of 380 miles is included too. - There is a severe weather warning, adding an element of unpredictability to the range test, since rain can impact energy consumption. - The cars are driven in "normal" mode at the speed limit with ventilation on. - Once low battery warnings appear, the speed is reduced, and eco mode is engaged to maximize range. - The BYD Seal is comfortable and quiet, with decent performance (312 hp from a rear drive motor, 0-62 mph in six seconds) and user-friendly Android Auto. The brakes feel "on-off," and the climate settings with Android Auto were not as good. - There is good knee room in the rear seats. However, there is less headroom. - The Tesla has a speedometer in the central screen requiring constant head movement to check the speed. - Overall the Porsche is the best-looking vehicle on test. - Limited power mode activates on the BMW once the car reaches 5% battery. - Real-world results were not as good as claimed for the BMW. - To determine the actual range of each car, they are all driven on a route in Scotland until they run out of electricity. - One car had to be pushed due to the charge point being close. - Cable length issues made charging a Tesla difficult. - The infrastructure of electric car chargers needs improvements. - One of the electric cars had a 4-kW battery due to only having 7 kW available. - 2 big men fit in the BYD's boot. - Air suspension is standard on the new Porsche and improves comfort on the car. - The Tesla wins at 4.8 miles per kWh, while other cars did less per kilowatt hour. - After going to 0%, Tesla did 23 miles, which are not included in its claimed range.
