BMW has announced a major breakthrough in electric vehicle technology with the introduction of its new Gen6 EV architecture. This new platform promises to bring cheaper electric cars to the market, offering increased range and improved efficiency compared to current models. The Gen6 architecture will debut with the upcoming Neue Klasse models, starting with the BMW iX3, set to be unveiled in September.
The key highlight of the Gen6 platform is the new nickel-manganese-cobalt (NMC) battery, which features cylindrical cells that are 20% denser and easier to package than the square cells found in current lithium-iron packs. These new batteries are said to deliver a 30% increase in range, 20% improvement in efficiency, and 30% faster charging speeds, with bi-directional capabilities. Additionally, production costs are reduced by up to 50% compared to current packs, allowing BMW to offer competitive pricing to customers.
The innovative cylindrical cells are available in two sizes and can be directly attached to the battery pack, eliminating the need for additional modules. This design not only saves costs but also reduces weight and size, allowing for slimmer batteries. By bolting the battery pack directly to the chassis, BMW has been able to enhance structural integrity, optimize car integration, save on parts, reduce weight, and maximize interior space.
In terms of electric motors, BMW has introduced the electrically excited synchronous motor (EESM) with four variants ranging from 270bhp to 400bhp, exclusively attached to the rear axle. A new addition to the Gen6 platform is the small asynchronous motor (ASM) available in 161bhp and 241bhp options, exclusively fitted to the front axle. This allows for tri- and quad-motor configurations alongside the single- and dual-motor setups currently available, catering to a wide range of models from entry-level to high-performance M cars.
Efficiency was a key focus in the development of these motors, with a dual-motor setup reducing inefficiencies by 40% compared to previous models. The motors are also 20% cheaper to produce and 10% lighter, contributing to overall performance improvements. BMW’s in-house production of batteries and motors across five factories on four continents ensures efficiency and robustness against future challenges.
Overall, the Gen6 EV architecture represents a significant leap forward in electric vehicle technology, promising more affordable electric cars with increased range, improved efficiency, and enhanced performance. With the Neue Klasse models leading the way, BMW aims to make electric mobility more accessible and appealing to a wider audience.
