GAC Aion has opened reservations for the Ray 7, the first model in its new Ray series and the first production car in the world to use Huawei's EMB electronic brake-by-wire system. Customers who place a deposit of 299 yuan (about $42) can unlock up to 8,999 yuan (about $1,267) in launch benefits, according to Chinese outlet D1EV.
Huawei tech inside
The mid-to-large BEV (battery-electric) sedan is built on Aion's AEP pure-electric platform and is fitted with a HUAWEI DriveONE multi-unit e-drive producing 180 kW (241 hp). It is the first vehicle to use Huawei's chip-level drive-brake fusion architecture, which allows motor and braking control to coordinate at the chip level with inter-core communication latency under 10 microseconds. Huawei's iTRACK dynamic torque distribution system is also included.
The headline feature is Huawei's EMB electronic brake-by-wire, a fully electric braking system with redundancy. GAC Aion claims a 100 km/h to 0 braking distance of 33 metres and says the system can still bring the car to a safe stop even if all four wheel brakes fail.
For driver assistance, the Ray 7 carries 27 vehicle-grade sensors, including one Huawei 192-line LiDAR and three 4D millimetre-wave radars. The ADAS algorithm is derived from WeRide's L4 Robotaxi technology, enabling features such as parking-space finding without a navigation route.
Big sedan, low drag
The Ray 7 measures 4,960 mm long, 1,900 mm wide and 1,455 mm tall, with a 2,920 mm wheelbase. Fourteen aerodynamic optimisations bring the drag coefficient down to 0.22. The body is a fastback coupe silhouette with semi-hidden door handles and a full-width rear light bar. Two paint colours are offered: Lightning Yellow, using a 5C3B premium spray process, and Midsummer Purple with ultra-fine aluminium powder.
Inside, the cabin features a digital instrument cluster, a three-spoke multifunction steering wheel, an electronic column shifter, a floating dashboard screen, a wireless charging pad and integrated front sports seats with extra shoulder support. A triple-layer silver-coated sunroof is standard.
The chassis uses front double wishbone and rear five-link suspension, with front and rear stabiliser bars, FSD variable-damping shock absorbers and HRS hydraulic rebound stoppers. GAC Aion quotes a CLTC energy consumption of 9.7 kWh per 100 km and a CLTC range of 700 km (around 560-595 km WLTP, est.).
The Ray 7 is expected to go on sale later this year. Pricing has not been announced.
