Chery claims a global first with EMB on the Oxid EX7
Chery has announced a major technical breakthrough: the Oxid EX7 will be the world’s first mass-production vehicle to use a pure electromechanical brake (EMB) or brake-by-wire system. Li Shouyong, Chery’s executive vice-president, unveiled the decision, saying the EMB-equipped Oxid EX7 will reach customers in the first quarter. By removing conventional hydraulic brake lines and translating driver inputs into electrical signals that actuate the calipers, Chery says braking response will be faster and stopping distances measurably shorter.
What makes the EMB different?
Unlike traditional hydraulic systems that rely on brake fluid and mechanical linkages, the EMB system uses electronic signals to directly control braking hardware. Chery’s engineering team spent three years on research and development to solve millisecond-level response, precise modulation and stability under demanding conditions. Integrated with Chery’s upgraded Flying Fish 3.0 chassis, the EMB forms part of a smart control network that behaves like an automotive "neural network," improving stability and safety across driving scenarios.
Powertrain and range: two versions for different needs
The Oxid EX7 will be offered in two configurations: a range-extender (series-hybrid) model and a full battery-electric version.
- Range-extender: roughly a 40 kWh battery, offering an all-electric WLTP-style range estimated between 180–200 km for everyday electric driving before the range-extender kicks in.
- Full electric: a large 97.7 kWh battery providing a claimed range of about 682–726 km, positioning the EX7 as a contender in long-range electric SUV segment.
These figures place the EX7 competitively among electric SUVs focused on range and tech, while the range-extender option addresses buyers seeking extended convenience without fast-charging dependency.
Advantages for drivers and the market
EMB or brake-by-wire is widely seen as the next evolutionary step in vehicle electrification and intelligent systems. Key benefits Chery highlights include:
- Faster brake actuation and more consistent pedal feel
- Easier integration with ADAS and automated driving systems
- Reduced mechanical complexity by removing hydraulic plumbing
- Potential for weight savings and better packaging
Quote: "This is a technological leap that redefines braking for production vehicles," said Li Shouyong, framing the EMB as central to Chery’s strategy for smarter, electrified platforms.
Market positioning and rivalry
Chery’s announcement comes amid a close race with Li Auto, which claims the L9 Livis will feature EMB. Chery points to official registration timing with China’s Ministry of Industry and Information Technology to support its claim: the Oxid EX7 reportedly entered the ministry’s approval list about three months earlier than its rival and is ready for production lines. Whether regulators, media and customers accept Chery’s "first" claim will depend on production dates and deliveries.
In short, the Oxid EX7 blends advanced braking tech with strong battery options and a smart chassis. For car enthusiasts and industry watchers, the EX7 is a sign that brake-by-wire is moving from prototypes into mainstream production—and that the competition to be first in new vehicle tech is intensifying.
Highlights:
- First claimed production EMB on Oxid EX7
- Two powertrain options: ~40 kWh REX or 97.7 kWh BEV
- Integrated with Flying Fish 3.0 chassis
- Aims to shorten stopping distance and improve integration with ADAS

Cool tech, but those range numbers feel optimistic. 97.7kWh and 700+ km? testing will show. EMB seems promising, yet reliability and serviceability matter a lot.

If Chery actually ships EMB first that's huge, but is this marketing spin? Regulators and real deliveries will tell... hope it's safe tho, brakes arent something to gamble with
