2026 Arcfox Alpha S5: EREV Joins the Sedan, AWD Hits 100 km/h in 3.7 s

The Arcfox Alpha S5 (Chinese name Jihu Alpha S5) is BAIC's mid-size electrified sedan, 4,886 mm long with a 2,900 mm wheelbase and a sloping fastback roofline. The updated car went on sale in China on 18 March 2026 and, for the first time, comes both as a battery-electric car (BEV) and as an extended-range electric car (EREV) with a petrol engine that only charges the battery. Seven versions cover three EREV and four BEV trims, with manufacturer's suggested prices from CNY 104,800 (~$15,721) to CNY 173,800 (~$26,071) and a launch benefit that takes CNY 5,000 off six of them (Arcfox's own page shows only CNY 2,000 off the BEV 720; CnEVPost reports CNY 5,000 across the lineup), so the cheapest car is advertised at CNY 99,800 (~$14,971). The EREV is rated at up to 1,450 km combined, the single-motor BEV at up to 720 km CLTC, and the dual-motor all-wheel-drive BEV accelerates from 0 to 100 km/h in 3.7 seconds with 390 kW (530 PS / 523 hp). On 23 October 2026 Arcfox opened pre-sale of a 2027 BEV-only Alpha S5 with standard lidar, a 148 L front trunk and rear-wheel drive, from CNY 121,800 (~$18,271); it is not on sale yet and has no launch date, so this article covers the lineup that can be ordered today and reports what is known about the update.

Performance & Specs

The EREV is the cheapest and, on paper, the longest-legged version. A 1.5-litre naturally aspirated petrol engine rated at 77 kW (105 PS / 103 hp) acts purely as a generator, and a single rear-mounted motor delivers 200 kW (272 PS / 268 hp) and 365 Nm to the rear wheels. Launch coverage quotes 0 to 100 km/h in 6.5 seconds with a charged battery (Sina gives 7.5 seconds with a depleted one), and Arcfox rates it at a CLTC electric range of 230 km from a 27.4 kWh lithium iron phosphate (LFP) battery made by CATL, and a combined range of up to 1,450 km. Some data sites still print 175 km for the electric range of these cars; the 230 km figure is the one used in the launch coverage and is used here.

The three single-motor BEV versions are listed as front-drive by Autohome and CarNewsChina; Arcfox does not state the drive layout. The 64.8 kWh car has a 185 kW (252 PS / 248 hp) motor with 320 Nm, accelerates from 0 to 100 km/h in 7.0 seconds and is rated at 630 km CLTC. The 74.4 kWh car uses a 200 kW (272 PS / 268 hp) motor with 360 Nm, reaches 100 km/h in 6.8 seconds and has the 720 km CLTC rating that headlines the range. The flagship is a dual-motor all-wheel-drive BEV with a combined 390 kW (530 PS / 523 hp) and 690 Nm, a 0 to 100 km/h time of 3.7 seconds and the same 74.4 kWh pack, which brings its CLTC range down to 650 km. Top speed is listed at 180 km/h on every version, and the figures sit in a neat order: the 3.7 second time belongs to the 650 km all-wheel-drive car, while the 720 km range belongs to the 6.8 second single-motor car.

Dimensions & Practicality

Length	4,886 mm
Width	1,930 mm
Height	1,480 mm
Wheelbase	2,900 mm
Boot	430 L

The body is 4,886 mm long, which is 66 mm more than the car before the update, 1,930 mm wide and 1,480 mm high, on a 2,900 mm wheelbase, and every version has the same dimensions. That puts it in the same size class as the BYD Seal 06 EV and a little longer than the Qin Max DM-i. Five seats are standard and the boot holds 430 litres, a modest figure for a car this long that reflects the low, sloping rear roofline. The EREV weighs 1,880 kg, the single-motor BEVs 1,885 kg and 1,995 kg, and the dual-motor car 2,120 kg, according to CarNewsChina's data sheet.

Charging & Battery

The BEV range is built on an 800V architecture. The reported peak charging power is 404 kW on the 74.4 kWh cars, which are the 720 km single-motor version and the 650 km all-wheel-drive version; CarNewsChina lists 215 kW for the 64.8 kWh car. For the 30 to 80 percent stop, Arcfox's site quotes 8.9 minutes under its 720 km pure-electric version, and CarNewsChina's data sheet gives about 9 minutes for both 74.4 kWh cars and about 15 minutes for the 64.8 kWh car. No 30 to 80 percent time was verified for the EREV. Arcfox's own site also advertises the car as having 540 km of range added in 15 minutes, a marketing figure that it does not tie to a trim, so the table below keeps to the 30 to 80 percent numbers.

Dividing the battery by the range gives about 10.3 kWh per 100 km for both the 64.8 kWh 630 km car and the 74.4 kWh 720 km car and about 11.4 kWh per 100 km for the heavier all-wheel-drive car, which is a believable CLTC spread. The EREV's 27.4 kWh pack is small, but the 1.5-litre generator and a 230 km electric range mean it can be driven as an electric car on most days. Reports on the March launch also list a lifetime warranty on the battery, motor and controller for first owners and battery replacement if capacity decays beyond a set limit within eight years or 150,000 km; those terms come from launch coverage and should be checked with a dealer.

BATTERY	27.4 kWh (EREV); 64.8 kWh and 74.4 kWh (BEV), LFP, CATL
DC FAST CHARGING	800V BEV line; up to 404 kW peak reported (74.4 kWh cars)
DC 30-80% TIME	About 9 min (74.4 kWh BEV); about 15 min (64.8 kWh BEV); not verified for the EREV

Design & Interior

Arcfox calls the styling the Wind-Sculpted design, and the exterior combines frameless doors, hidden door handles, an active front air intake, slim headlights, a floating two-tone roof and a through-style tail light bar with the ARCFOX lettering across it. The update brought a redesigned front end with the extra lower lighting elements removed, new bumpers and seven body colours, three of them new: Phantom Green, Varna Blue and Lava Grey. The green car in Arcfox's own images wears green brake calipers and multi-spoke wheels and a retractable rear spoiler sits on the boot lid.

Inside, the dashboard is built around a large central touchscreen and the headliner has 256-colour ambient lighting. The front passenger gets a zero-gravity seat with an integrated leg rest and sport-style velvet upholstery, and the interior is offered in three colour schemes, including a new brown. The launch material also lists a 68-inch augmented-reality head-up display, a 19-speaker audio system, massage and ventilated seats and a heat-pump climate system, though which of these come on which trim was not published in the sources used here.

Technology & Features

Both the cockpit and the driver-assistance functions run on one Qualcomm Snapdragon 8775 chip. The driver-assistance suite is BAIC's Yuanjing system, which Arcfox's site lists with urban navigation assistance (the page advertises it from the CNY 110,000 class) and Zhuoyu binocular stereo-vision hardware. A blue light on the car shows when the system is active. The car uses a chassis tuned together with Magna and an adaptive damper setup, and the dual-motor car has a dedicated boost button.

Safety & ADAS

The 2026 car relies on cameras and radar and has no lidar. That changes on the 2027 version, which opened pre-sale on 23 October 2026 with a 192-line roof-mounted lidar as standard on all three versions (CnEVPost; Arcfox's configuration page also lists lidar as standard), and the same sensor appeared in a Ministry of Industry and Information Technology filing in the September 2026 batch with unchanged dimensions of 4,886 by 1,930 by 1,480 mm. The lidar supplier has not been named by Arcfox, and dealer-sourced reports that name one are unconfirmed. Crash-test results for the updated car were not found in the sources used.

ADAS LEVEL	L2+ (Yuanjing navigation assistance; BAIC does not quote an SAE level for the Alpha S5)
ADAS FEATURES	Urban and highway navigation assistance, automated parking, radar and camera sensor suite (sensor count not published by Arcfox); no lidar on the 2026 car

Pricing & Availability

The manufacturer's suggested prices are CNY 104,800, 111,800 and 124,800 (~$15,721, ~$16,771 and ~$18,721) for the three EREV versions and CNY 116,800, 128,800, 141,800 and 173,800 (~$17,521, ~$19,321, ~$21,271 and ~$26,071) for the four BEV versions, converted at the ECB rate of 1 USD = 6.6664 CNY (28 October 2026). Six of the seven versions carry a launch benefit of CNY 5,000 that Arcfox counts as a purchase-tax subsidy, which gives the advertised range of CNY 99,800 to 168,800 (~$14,971 to ~$25,321); on Arcfox's own price page the BEV 720 drops only CNY 2,000, to CNY 139,800 (~$20,971), while CnEVPost and CarNewsChina report CNY 5,000 off every version. Arcfox's website, read on 30 October 2026, advertises the car from CNY 99,800 as a limited-time offer, with benefits of up to CNY 31,688 (~$4,753) that run until 31 October 2026 inclusive and vary by trim and dealer. Dealer promotions in China have often been deeper than the official list, so the real transaction price can differ by region.

The updated Alpha S5 is sold in China, where Arcfox sells it through BAIC's dealer network and the Arcfox app. Egypt has an older-specification car listed at EGP 1,500,000 and 1,650,000 with a 65 kWh battery and about 560 km, according to local price sites in October 2025, and Arcfox has announced a Malaysian entry under GoAuto Group; its global site lists an S5 sedan among the models, but no Malaysian launch date or version has been given. No export version of the updated EREV and BEV lineup has been confirmed in Europe, North America or Israel as of October 2026. The 2027 model-year car is in pre-sale, not on sale. Arcfox's user-operations vice president Qiao Xinyu previewed it on 14 October 2026, and pre-sale opened on 23 October 2026 with three BEV versions: the 650 Plus LiDAR at CNY 121,800 (~$18,271), the 650 Max LiDAR at CNY 131,800 (~$19,771) and the 750 Max LiDAR Shenxing at CNY 144,800 (~$21,721), according to Arcfox's own site and CnEVPost. All three have rear-wheel drive, a 148 L front trunk and a standard lidar, with pre-sale benefits worth CNY 18,800 (~$2,820). These are pre-sale prices, no official launch date has been announced, and Arcfox has not said whether the 2026 EREV versions and the all-wheel-drive flagship continue next to it.

How It Compares

The Alpha S5 is the only car in this group sold as both a BEV and an EREV, and it also has a 3.7 second all-wheel-drive flagship under the same nameplate. The BYD Seal 06 EV, a 4,870 mm electric sedan, starts at CNY 109,900 and reaches up to 630 km CLTC with up to 322 hp, so the Arcfox BEV 720 at CNY 141,800 offers 90 km more range and a larger battery, while BYD's cheaper trims undercut the Arcfox's single-motor BEVs. The Geely Galaxy TT is a rear-drive 800V sedan with up to 725 km CLTC and up to 570 hp, which is within reach of the Alpha S5 AWD at 523 hp and 650 km and shows how crowded this price range has become. The BYD Qin Max DM-i, a 235 hp plug-in hybrid (PHEV), is the price match for the EREV at CNY 99,900, and it claims up to 2,370 km combined against the Arcfox's 1,450 km, but it is a front-drive hybrid. Rival figures are taken from our own articles on each car, in each car's own exchange rate.
