US car giant General Motors has unveiled an all-new electric car battery, capable of offering up to 400 miles (643km) of range in a single charge, with GM claiming it will eventually cost under US$100 per kilowatt hour (kWh).

Part of the third-generation electric car platform unveiled by GM this week, the Ultium battery cells can be used in up to 19 different configurations due to their stackable, pouch-style format and will be used to underpin several of GM's electric car launches over the next three years.

The Ultium batteries range from 50kWh to 200kWh, with GM estimating a top-end range of "400 miles or more" and a 0-60m/h (roughly 0-100km/h) sprint in 3 seconds.

GM has promised that the new technology, produced as part a joint venture between GM and Korean company LG Chem, will "drive battery cell costs below $100/kWh".

GM says its in-house-designed motors will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications.

The Ultium batteries will be utilised in the upcoming GMC Hummer EV, which will be revealed on May 20 this year, as well as the Cruise Origin, a new self-driving share vehicle, and the Cadillac Lyriq, an incoming luxury SUV.

The new architecture is part of GM's wide-ranging strategy to grow its "electric vehicle (EV) sales quickly, efficiently and profitably".

"GM is building toward an all-electric future because we believe climate change is real," GM CEO Mary Barra said at the platform's launch.

“What we have done is build a multi-brand, multi-segment EV strategy with economies of scale that rival our full-size truck business with much less complexity and even more flexibility.”

Currently, Tesla holds the title for world's longest range on its electric cars.

The Tesla Model S Long Range available in Australia and New Zealand has a range of 610km (WLTP), while the Model S Long Range Plus, which is only available in the US, Canada and Mexico, claims a range of 630km.
