Kuaidi Technology reported on November 11 that the prototype of the Mercedes-Benz CLA all-electric model recently reached a new world record: the record for the longest mileage traveled in 24 hours for a pure tram model.
Its score was 2,309.
6 miles in 24 hours, equivalent to 3,716.
9 kilometers, breaking the score of 2128 miles (equivalent to 3427 kilometers) set by Porsche Taycan.
Simple calculations show that CLA ran 181.
6 miles (about 289.
9 kilometers) more than Taycan.
It is reported that both cars were tested on the Nardò test track in Italy.
This is an elliptical track with a total length of 7.
8 miles (about 12.
55 kilometers).
Based on the mileage traveled, the average speed of Mercedes-Benz CLA is about 95mph, equivalent to 154.
9 km/h.
Of course, it is impossible to use only one box of electricity for this test, so this not only tests the energy efficiency of the car, but also tests the charging speed of the test car.
At the same time, an excellent testing strategy is also needed.
The strategy adopted during the Mercedes-Benz test was: not charging much each time, but charging for the most efficient 10 minutes, just charging from below 10% to about 55%.
Finally, a total of 40 charges were charged in the 24-hour challenge, and the charging took 6 hours and 40 minutes.
Based on this calculation, CLA ran a total of about 17 hours and 20 minutes, with a dynamic average speed of 133.
24 mph, equivalent to 214.
44 km/h.
In fact, this seems to be not only an energy efficiency challenge for a 24-hour driving distance, but also an endurance test for high-speed motor driving + high-frequency and high-power battery charging and discharging.
, It is reported that the motor power of the CLA single motor version is about 175 kW, the WLTP battery life is 750km, and the peak charging power is 250kW.
