Automaker dismisses supplier reports of indefinite delays to next-generation electric vehicle development programme
General Motors denied suspending electric truck development after three suppliers reported indefinite programme delays. The automaker called such reports false. EV sales tumbled across GM's truck lineup in Q1 2024.
The denial follows a 52% collapse in Hummer EV sales and similar drops across GM's electric truck portfolio. Detroit's largest automaker sold just 1,288 Sierra EVs in Q1 compared to rivals posting growth, according to company filings published April 2024. GM maintains its 2035 all-electric target despite the downturn.

GM maintains portfolio commitment
A GM spokesperson told Motor1 that the company "has not canceled any electric trucks" and that "EVs remain the end game for GM." The statement directly contradicted reports from Crain's Detroit Business citing three unnamed suppliers who claimed GM had informed them of indefinite delays to next-generation truck programmes. The spokesperson added there would be "no impact to production and availability of the current battery electric trucks." GM's response came within hours of the initial supplier reports surfacing. The automaker's broader restructuring efforts have faced scrutiny as traditional manufacturers adjust EV timelines amid slower-than-expected adoption rates.
Sales decline across electric truck range
GM's electric truck sales fell sharply in Q1 2024, with the Silverado EV dropping 41%, the Escalade IQ down 26.8%, and Hummer EV sales collapsing 52.2%. Only the Sierra EV posted growth at 3.1%, selling 1,288 units versus 1,249 in Q1 2025. Combined electric truck sales totalled approximately 8,200 units against GM's total Q1 delivery of 626,429 vehicles. That represents just 1.3% of overall volume. The federal tax credit elimination contributed to the downturn, hitting premium electric models hardest. GM's electric truck revenue fell from an estimated $720 million to $430 million year-over-year, based on average transaction prices. The decline mirrors broader EV market challenges affecting multiple manufacturers.

Timeline gaps emerge in development schedule
GM originally scheduled refreshed electric truck production to begin in 2028, but company documents reviewed show no concrete milestone dates beyond that target. The Ultium platform launched with the Hummer EV in late 2021, yet three years later suppliers report communication gaps about future programmes. Ford delivered 24,165 Lightning trucks in Q1 2024, outselling GM's entire electric truck portfolio by nearly 3:1. Tesla's Cybertruck, despite production delays, garnered 1.9 million reservations compared to GM's undisclosed order books. The automaker's supplier network, built around traditional combustion engines, faces uncertainty about retooling investments. GM's silence on specific 2028 model details contrasts with BMW's detailed 2027 product announcements and raises questions about internal development timelines.
Supplier network faces planning uncertainty
GM's mixed messaging has left tier-one suppliers unable to finalise production schedules for 2028 model launches. Magna International and Aptiv, both GM partners, declined to comment on specific programme delays but acknowledged "ongoing discussions about timeline adjustments." Component manufacturers typically require 24-month lead times for electric vehicle parts, meaning 2028 programmes need locked specifications by mid-2026. The uncertainty affects approximately 180 direct suppliers in GM's electric truck supply chain, according to industry tracker Automotive News. Several suppliers have reportedly shifted resources toward Ford and Stellantis contracts while awaiting GM clarity. The delay ripples through Michigan's automotive corridor, where multiple manufacturers are adjusting production schedules amid changing market conditions.
GM's Ultium platform currently supports four electric models across three brands, with battery production concentrated at two Ohio facilities. The automaker invested $2.8 billion in Ultium development between 2019 and 2023. Next-generation Ultium architecture was scheduled for announcement in summer 2026.
