BMW tested the performance and reliability of its 2023 BMW i7 electric sedan through various tests before it goes on sale. Earlier this month, BMW released spy photos of its electric sedan. And we now have another set of new photos of the upcoming electric and luxury sedan. The new G70/G71’s testing process will take place on steep mountain roads and in hot weather conditions.Â
The performance of the BMW i7 is the key data that the development engineers will test. Data includes the model’s all-wheel drive, high-voltage battery and electric motors. The car will be exposed to heat, dust at various altitudes and unpaved roads. From gravel roads into the desert to narrow and steep roads, the i7 gets through these obstacles for the endurance test.
BMW ensures the best components of the electric drive system by testing the endurance of the car in various hot regions of the world. How the i7 sedan’s massive components respond to driving conditions will provide data for the engineers. This includes measuring the combined cooling system, the high-voltage battery and the electric motors. Naturally, BMW has also checked the charging strength, energy management and brake regeneration.
The test programme also includes mountain driving in trailer mode to further increase the load on the drive system. At the same time, BMW i7’s skill to constantly provide peak power to the e-motors becomes possible, thanks to its high-voltage battery. Some other cars have problems when they can’t absorb restoration energy. Thus, the test will also include driving downhill with a fully-charged battery.
As rumoured, the i7 will feature high-spec electric motors on the front and rear axles. According to WLTP, the i7 will also come with a large 120-kWh battery pack and a 650-hp engine. This means the i7 can last up to 435 miles of driving. Many are looking forward by BMW’s 105-kWh battery on the floor, powered by two motors and an all-wheel-drive system. Car enthusiasts look forward to the upcoming 7 Series’ making in July and its sales to kick off in 2022.
