At the GM Forward event held in New York, U.S., on October 21, GM revealed its innovative development direction for a 4th-generation electric vehicle platform that organically integrates batteries, electric drive systems, and centralized computing.

This 4th-generation platform focuses on designing the entire vehicle as one large organic system, going beyond improving the performance of individual components. According to GM's initial development review results, combining a new lithium-manganese-rich prismatic battery, an advanced electric drive unit, and optimized aerodynamic design improved the driving distance per kilowatt-hour of energy by more than 20% compared to current vehicles.

The platform's core technology, the lithium-manganese-rich battery, is set to be applied across key EV segments where driving range and price competitiveness are crucial. It is designed to maintain a cost level similar to that of the popularized low-cost lithium iron phosphate (LFP) battery while increasing energy density by 33%. The company explained that this allows for stable securing of top-tier driving range in its class with smaller, lighter battery packs.

The lithium-manganese-rich prismatic cells are planned to be produced entirely at Ultium Cells' Spring Hill plant in Tennessee, U.S., a global joint venture between General Motors and LG Energy Solution. Meanwhile, the newly developed drive unit aims for simultaneous vehicle weight reduction, securing of wider interior space, and production cost savings by miniaturizing the motor and power electronics devices and significantly reducing the number of internal components by 40% compared to existing models.

The centralized computing architecture strongly supports efficient energy management and software-centric feature improvements. It significantly reduces the complexity of control modules and wiring compared to current EVs, greatly enhances the responsiveness of display and voice control systems, and provides a foundation for continuously advancing advanced features such as Super Cruise and OnStar. General Motors plans to actively expand the application scope of its 4th-generation EV platform, which bundles lithium-manganese-rich batteries, new drive systems, and centralized computing, into major vehicle segments, thereby broadly providing more customers worldwide with opportunities for affordable electric vehicle choices.
