It could be the end of an era for American pride. Or just business. Reuters says the next-gen Cadillac Optiq might roll onto a platform built right here in China. The name? Xiao Yao. It was co-developed by GM’s joint venture partner, SAIC.
It’s not speculation. A source with direct knowledge dropped this intel. The Optiq. GM’s crown jewel. Getting a Chinese chassis. At least if it sells in China.

What is Xiao Yao anyway
Launched in 2024. Currently supports three Buick models. The Electra L7 sedan (both EV and range-extended versions). The Encasa MPV. The big E7 SUV.
GM promised six Buicks would use this tech within a year of launch. That window closed months ago. So far, only three showed up. Still, the specs look decent. 900V electrical architecture. Lithium-iron-phosphate batteries. Fast charging. Things matter here.
“The Xiao Yao architecture is China-tailored… The reporting about the Optiq is.”
GM didn’t deny it. They called it speculative. Typical corporate waffle. But notice they didn’t say it wasn’t true.
Why change the horse now
Look at the rest of the lineup. GM pushed its global BEV3 Ultium platform into China too. It worked… mostly. 400 voltage. Slower charging than the 800 or 900 volt setups locals demand. The Buick Electra E4? Lasted barely two years. The Cadillac Optiq stopped producing here altogether. Even regular Lyriqs vanished from the site earlier this year.
Only the niche Lyriq-V and Vistiq remained. Sales were limp.
Meanwhile, Kurt Kelty, GM’s battery boss, said in June they are shoving US resources into lithium manganese batteries. They shelved plans for US LFP production. Irony? China goes all-in on LFP. GM China is too. They’re even working with CATL on 640kw charging tech.
So why build one car for two worlds. The Xiao Yao split might just be inevitable.
Is there a loophole?
Maybe the US stays safe. Regulations there block Chinese software. So you won’t see an Xiao Yao Cadillac at a suburban driveway in Ohio anytime soon. But exports? Different story.
The Buick E7 is already headed to South Korea on this platform. What stops it going to Europe. Or Australia. The current Optiq is made in Mexico. Ships everywhere.
If GM uses the Chinese platform for the replacement. Where does that build? Who buys it. We don’t know. Yet.
The trend isn’t new
Look around. Non-Chinese brands are waking up. Or finally paying attention. Changan-Mazda just unleashed electric CX-6e and 6e models. They’re shipping to Australia. Japan. Europe. Dongfeng-Nissan is rolling out PHEVs. Ford-JMC is preparing its New Energy Bronco.
Jeff MacDonald. Cadillac’s chief engineer for Lyriq/Vistiq. He was in Beijing watching. Really watching.
“I’m really close to the pulse of,” he told reporters in June. “Benchmark across all of them… Huawei… Xpeng… Nio.”
He sounds worried. Or at least keen.
GM watches closely.
The divide is stark. The US pulled EV tax credits. Loosened emission rules. Gasoline makes a comeback. China dives headfirst into EVs and range extenders. Traditional combustion is dying out. Two different planets under one logo.
Does it matter? Maybe not. As long as the wheels turn.
