After witnessing Tesla’s scale and manufacturing capabilities, because of simplified architectures and fewer parts, most automakers are mimicking the method.
The trade has realized that lean manufacturing may also help them cut back losses of their EV companies and put them on the trail to profitability. Normal Motors CEO Mary Barra defined that intimately in yesterday’s second-quarter earnings name. She revealed that the 2025 Cadillac Lyriq featured 24% fewer elements than the 2024 mannequin yr. It seems that the Lyriq isn’t the one GM mannequin on a food regimen.
The race to make EVs worthwhile.
EVs are less complicated than fuel vehicles, packing fewer parts, requiring much less upkeep and saving loads of money in the course of the possession interval. It is nearly counter-intuitive that reaching this simplicity includes painfully advanced engineering and redesign to scale back prices on the manufacturing line and cross on these cost-benefits to clients.
GM instructed InsideEVs at present that every one new Ultium-based Chevrolet and Cadillac fashions would function fewer parts than earlier than to scale back prices and enhance manufacturing effectivity.
“Throughout yesterday’s name, the Lyriq was used for instance of what the workforce was in a position to obtain by means of Profitable with Simplicity, a company-wide initiative that impacts all autos that can launch this yr,” a GM spokesperson mentioned. “Cadillac in addition to Chevrolet clients will discover fewer trim mixtures and extra customary content material on sure fashions.”

On the earnings name, Barra mentioned this was essential to enhance the corporate’s margins. With what she known as “smarter contenting and optimizing selectable choices,” GM was in a position to eradicate greater than 2,400 distinctive elements on ten autos it plans to launch by means of the primary quarter of 2025. It’s unclear if all these are EVs, however now we all know they embrace fashions just like the Chevy Equinox EV, Blazer EV, Silverado EV, and Cadillac Optiq, amongst others.
“The record of elements that we not must design, engineer, supply, set up … is in depth,” Barra mentioned. In response to her, this contains seat assemblies, consoles, and door trims, which require advanced engineering and are comparatively pricey. “An important ingredient is lowering the variety of buildable electrical mixtures, which is delivering {hardware} and software program high quality enhancements in addition to financial savings.”
Rivian took the same method with its second era R1S and R1T. It contains eliminating 1.6 miles of inside wiring and lowering the variety of digital management models (ECUs)—units chargeable for controlling particular capabilities in a automobile—from 17 to simply seven.
GM says this method would assist it save $2 billion {dollars} in what it calls a “fastened price discount program.” The financial savings are anticipated to be even larger within the years to return. It’s too early to decipher the implications of those lean manufacturing targets. Nonetheless, it appears to have labored for Tesla, albeit after present process a “manufacturing hell” part. We’ll regulate the way it works out for GM.
