The Arcfox Beta S3 (Chinese: 极狐贝塔S3) is a battery electric executive sedan manufactured by BAIC under the Arcfox brand.[1][2]
Overview
The Beta S3 was introduced in April 2026 at the Beijing Auto Show.[3]
The Beta S3 is strictly front-wheel drive only and powered by a permanent magnet synchronous motor with a maximum power output of 159 kW (213 hp) and 250 N·m of torque. 0 to 100 km/h acceleration time is 7.1 seconds. There are two versions of the Beta S3 offered. The battery-swapping variant utilizes CATL’s battery swap network, and features a CLTC range of 535 km and supports battery swaps to be done in 99 seconds. The charging model offers a CLTC range of 560 km or 660 km base on battery spec, and fast charging from 30% to 80% takes 28 minutes.[4]
The Beta S3 is equipped with the 8155 chip of Qualcomm Snapdragon as standard, and more upmarket trims feature the “Yuanjing” intelligent driving assistance system, which utilizes a 192-line LiDAR and the Horizon Robotics Journey J6M chip to achieve autonomous and driving assist features.[4]

Interior
Beijing EU8
Launched by Beijing Auto in May, 2026, the Beijing EU8 is essentially a rebadged variant of the Arcfox Beta S3 targeted at the ridehailing market. From the exterior, the EU8 features a restyled front end giving it a more featureless anonymous look. Just like the Beta S3, there are two versions of the EU8 aimed at different taxi vehicle markets, a battery-swap version with a CLTC range of 535km, and a charging version with a CLTC range of 501km.[5]
