CTOnews.com, Nov. 10 (Xinhua) BMW's dedicated platform for Neue Klasse electric vehicles is crucial to the brand's success in the electric era, and the platform is scheduled to be launched in 2025, when the i3 and iX3 successors will be launched. New Neue Klasse cars are expected to account for more than half of BMW's global sales by 2030, and Frank Weber, BMW's chief technology officer, revealed some of the parameters and specifications of the models that will use the platform.

According to Weber, electric vehicles using the Neue Klasse platform will use a new generation of battery and motor technology to achieve a "huge technological leap". The Neue Klasse electric car will adopt a new concept called "pack-to-open-body", which will allow BMW to customize its battery size to suit any model by using a circular battery instead of a prismatic battery.

BMW will add some of these technologies to the lineup of Neue Klasse electric vehicles, from 1-series sedans to X7-class large SUV. Compared with the batteries currently used by BMW, these electric vehicles will benefit from batteries with 20% higher energy density, 30% higher packaging efficiency, 30% better battery life and 30% higher charging speed. In addition, the new battery is said to be 20% lighter, production costs reduced by 50%, and carbon dioxide emissions during production are estimated to be reduced by 60%.

The BMW round battery unit (right) and the prismatic battery unit (left) Weber also revealed: "the combination of the new car's 800V high voltage system and high-performance charger can increase the new car's range by 48km per minute, up to 600km." This means that it takes only about 12 minutes to charge the battery pack from zero to 95% of the battery.

On the power side, the Neue Klasse platform will provide power output from 268 horsepower to 1341 horsepower, and the architecture can accommodate up to four motors. At present, the BMW M brand is already testing the first pure electric model with four motors.

Most future Neue Klasse models will be rear-drive and four-wheel drive, with one or two SSM motors to drive the rear wheels. BMW said the SSM motor has stable peak performance, high energy density, good repeatability, low noise emissions and 97 per cent efficiency.

The platform's battery packs range in capacity from 75kWh to 150kWh and provide a range of up to 621mph (1000 km). But Weber believes that making a fuss about battery power and battery life is not the solution, because the effects of size and weight are counterproductive. Instead, BMW focuses on improving the energy efficiency of its vehicles. According to Thomas Albrecht, the boss of Efficient Dynamics, Neue Klasse will increase aerodynamic efficiency by at least 25 per cent. BMW is also working on A + tires, which are said to reduce rolling resistance by 7 per cent, while improved low-loss hub bearings and friction-optimized braking systems should further improve efficiency by 4 per cent.

CTOnews.com learned that BMW will preview the Neue Klasse platform with a Vision concept car at the 2023 International Consumer Electronics Show in January.
