The brief

Analyst view

• Ultium is a flexible platform: different battery packs fit different vehicle shapes with reused motors and electronics.
• Chevy Bolt EV/EUV is the volume leader; 9 Ultium EVs are in production across four brands.
• Shifting from LFP to LMR cells: 33% higher energy density at comparable cost, aiming for 2028.

Technical approach

As reported

Platform

Flexible skateboard for many vehicle shapes

Different battery packs under the floor fit sedans, SUVs and trucks with the same motors and electronics, cutting development cost and tooling.

Battery

LMR cells 33% more energy than LFP

Lithium-manganese-rich cells use manganese in the cathode; 33% higher energy density at comparable cost.

Powertrain

Single-speed drivetrain simplifies cost

Electric motors deliver peak torque from zero, so single-speed transmission suffices; simpler and cheaper than gas cars.
