BMW i7 enters final phase of testing in extreme road and weather conditions

In a recent press release, BMW announced that the series development process for the world's only pure-electric powered luxury sedan — the BMW i7 — is entering its final phase. The BMW i7 is being put through its paces through a demanding test program in extreme road and weather conditions.

According to BMW, the prototypes of the BMW i7 are being tested over gravel tracks into deserts, into the mountains, and on a whole series of highly dynamic routes.

BMW also revealed that pre-production models of the i7 are subjected to endurance evaluations in the hot regions of various countries and continents to test and safeguard all components of the electric drive system.

The testing program, which covers tens of thousands of kilometers, includes long-distance and high-speed driving as well as stop-and-go traffic in scorching heat. In addition, test sections with particularly large differences in altitude were selected at the hot-region test sites.

The German automotive brand shares that one of the reasons why the i7 is put through such rigorous testing is to verify the performance and reliability of the electric motors, the all-wheel-drive system, and the high-voltage battery when being exposed to maximum stress from high temperatures, unpaved roads, dust and large differences in altitude.

Earlier this month, BMW announced in a separate press release that the BMW i7 has undergone driving dynamics testing at the BMW Group winter test center in Arjeplog, Sweden. In this testing phase, the suspension components, steering and braking systems as well as driving dynamics and vehicle stability systems developed for the luxury sedan were assessed and examined.

Pretty much like the hot-region tests, the cold-climate trials were designed to simulate the challenges faced by a series-production vehicle during a complete product life cycle and analyze how it performs in diverse and adverse weather and climate conditions.

More details about BMW’s latest luxury sedan are expected to be announced as it nears launch in 2022.
