GM unveils fourth generation EV platform with production lithium manganese rich battery and simplified drive units
By Eve
General Motors has launched its fourth generation electric vehicle platform featuring the world's first production lithium manganese rich (LMR) battery, developed with LG Energy Solution through the Ultium Cells joint venture. The new platform delivers approximately 20 per cent more range per kilowatt hour, with the LMR chemistry offering 33 per cent more energy density than lithium iron phosphate at comparable cost. GM's redesigned electric motors and power electronics cut drive unit parts by 40 per cent, creating a smaller and lighter system for high volume vehicle segments.
Why it matters
The production ready LMR battery technology and simplified drivetrain architecture signal a major procurement shift for charging infrastructure providers, as higher energy density vehicles with extended range will influence charging speed requirements and site utilisation patterns. GM's focus on high volume segments at LFP comparable pricing could accelerate EV adoption rates, driving demand for expanded charging networks across the United States.

BYD workforce hits 1.02 million, exceeding Toyota, GM, Ford and Tesla combined
BYD now employs more than 1.02 million people, including up to 120,000 R&D engineers, chairman Wang Chuanfu told the China Society of Automotive Engineers' 33rd annual conference on Wednesday. The Chinese automaker added roughly 150,000 staff in 10 months despite falling vehicle sales, bringing its total above the combined headcount of Toyota, GM, Ford and Tesla. Around 960,000 work in China and 60,000 abroad, with R&D focused on battery cells, motors, electronic controls and semiconductors.
Why it matters
BYD's vertical integration strategy, keeping batteries, chips and motors in house, underpins its scale and signals intensifying competition for EV supply chain talent and manufacturing capacity. The workforce expansion, even as sales dip, suggests the company is investing heavily in R&D and production infrastructure that could reshape global EV and charging component markets.
iCaur SUVs reportedly planned for France in early 2027, according to Frandroid
Frandroid reported on 27 October 2026 that iCaur, a brand linked to Chery, is aiming to launch the V25 and V27 SUVs in France in early 2027, with the V23 following later without a firm date. The V23 would need structural modifications before homologation, which Frandroid does not detail. The timetable comes from the press rather than the manufacturer, powertrains for France are unconfirmed, and nothing in the sources shows any of the models can yet be ordered in France.
Why it matters
A new Chery-linked entrant could add electric or range-extender SUVs to the French parc from 2027, but with no confirmed powertrains or manufacturer commitment, planning on charging demand or fleet supply should treat this as an unverified signal. It is worth tracking as a competitive-map item rather than a firm market input.
Tata Motors reportedly developing Kuno mid-size electric SUV for 2027 to 2028 launch to rival MG Windsor
According to people familiar with the programme, Tata Motors is developing a ground-up, roughly 4.3-metre mid-size SUV codenamed Kuno, scheduled for introduction in 2027 to 2028 and likely to be built at Sanand in Gujarat. Planned annual production is around 80,000 to 100,000 units, which the report says is a capacity plan and not a first-year sales forecast. The commercial name, final specifications and pricing have not been disclosed, and Tata is preparing capacity additions at Sanand, which includes the former Ford plant.
Why it matters
A further mid-size EV line from Tata, alongside the new-generation Nexon, Curvv and Sierra, points to a larger family-oriented EV parc in India from 2027 to 2028, which could support longer-term charging demand planning. Planned volumes of 80,000 to 100,000 units a year at Sanand suggest the scale of vehicle supply CPOs and site hosts may need to anticipate, though timing and specifications remain unconfirmed.
