BYD Atto 2 (Yuan UP) Versions Compared: 301 km vs 401 km, 70 kW vs 130 kW

The 2025 BYD Atto 2 (sold in China as the Yuan UP) comes in three versions on one body: 301 km with a 32 kWh battery and a 70 kW motor, 401 km with a 45.12 kWh battery and a 70 kW motor, and 401 km with the same battery and a 130 kW motor. The two 401 km versions are the trap. They show the same range figure, but one reaches 100 km/h in 12.9 seconds and the other in 7.9 seconds, and BYD’s sheet lists curtain airbags only on the faster one. Order an Atto 2 by motor output and trim, not by range.

The three versions side by side

Figures are from BYD’s published configuration sheet for the 2025 model-year Yuan UP. The 301 km version was added in July 2025; the two 401 km versions launched in February 2025.

All three share the same body: 4310 × 1830 × 1675 mm on a 2620 mm wheelbase, front-wheel drive, MacPherson front and torsion-beam rear suspension, 215/65 R16 tyres and a 5.25 m turning radius.

“Not listed” means BYD’s 2025 sheet shows the feature as absent on that version. Check the actual unit before you tell a customer either way.

The 401 km trap: same range, two different cars

This is an ordering mistake we have seen with the Atto 2. A buyer asks for “Atto 2, 401 km”, the supplier ships the cheaper 70 kW version, and the customer gets a car that takes five seconds longer to reach 100 km/h.

Five seconds is the difference between a car that merges confidently onto a highway and one that needs planning. With five people on board, or on a long uphill, the 70 kW version feels its limits. The 130 kW version doesn’t.

The equipment gap matters just as much. On BYD’s sheet, the 401 km / 70 kW version doesn’t list curtain airbags; the 130 kW version does. If your market has safety-conscious buyers, fleet customers with insurance requirements or a crash-rating question at registration, that line decides the order.

Check three things on the VIN before you pay a deposit:

1. Motor output: 70 kW or 130 kW.
2. Battery capacity: 32 kWh or 45.12 kWh.
3. Trim: the equipment list, including airbags and driver assistance.

Our inspection and condition report records all three, and our checklist of import traps covers similar mistakes on other models.

The 301 km version: cheapest, lightest, fewest features

The 301 km version is the newest and simplest. Its 32 kWh battery saves 90 kg against the 401 km / 70 kW car, which is why it is actually slightly quicker to 100 km/h (12.0 s against 12.9 s) despite the same motor.

What it gives up:

• 100 km of rated range.
• Fast-charge peak: 45 kW against 65 kW.
• Driver assistance: standard cruise control only, with no lane keeping or automatic emergency braking listed.
• Screen: 10.1 inches against 12.8.
• Curtain airbags and V2L output: neither is listed on the sheet.
• Top speed: 150 km/h against 160 km/h.

For a city-only buyer on a tight budget who charges at home, the 301 km version is a reasonable car. For anyone else, the 401 km versions are the safer recommendation.

Range in real use

All three versions use almost the same energy per kilometre: 12.0 to 12.2 kWh per 100 km. The range gap comes almost entirely from battery size.

CLTC figures are generous, and real-world range will be lower, especially at highway speed. As a planning rule, treat the 301 km version as a city car that needs charging every two or three days at moderate daily mileage, and the 401 km versions as cars that can manage a full working week of city driving for many private owners.

In Ethiopia, public charging is concentrated in Addis Ababa, with roughly 100 stations against an estimated 2,300 or more needed nationwide. For buyers who leave the city regularly, the 401 km versions are the minimum we would recommend. See our Ethiopia EV import guide for the charging picture.

Altitude and hills

Addis Ababa sits at around 2,355 metres. Electric motors don’t lose power with altitude, so each Atto 2 version delivers its full rated output in the highlands. That’s a real advantage over small petrol SUVs.

What altitude doesn’t fix is the gap between 70 kW and 130 kW on a steep climb with a full load. For hilly cities and mountain roads, the 130 kW version is the one to stock.

Atto 2, Yuan UP, and the other names

In China this car is the BYD Yuan UP (元UP). In export markets it is mostly sold as the Atto 2, and in some places as the Yuan Pro or S1 Pro. Chinese paperwork for a car bought from the domestic market will usually say Yuan UP.

The Atto 2 is not a smaller version of the Atto 3. The Atto 3 (Yuan Plus) is one size class up: 4455 mm long against 4310 mm, with a 2720 mm wheelbase and multi-link rear suspension. If your customer is choosing between the two, see Yuan UP vs Yuan Plus (Atto 2 vs Atto 3).

Export-market Atto 2 versions built for Europe or other regions may have different batteries and equipment from the China-market Yuan UP. This page covers the China-market car, which is what most independent exporters ship. Our guide to Chinese model names vs export names explains why this matters.

Which version for which buyer

301 km / 70 kW fits:

• Private city drivers on the lowest budget who charge at home.
• Short-distance delivery or business use inside one city.

401 km / 70 kW fits:

• Buyers who need the range but mostly drive in flat city traffic.
• Price-sensitive customers who accept slower acceleration and fewer airbags. Make sure they know about the airbag difference.

401 km / 130 kW fits:

• Most private buyers. It’s the version we would recommend by default.
• Hilly cities, highway driving and full passenger loads.
• Fleet and corporate customers who need curtain airbags and driver assistance.
• Ride-hailing drivers, subject to local licensing rules.

If your customer wants more space, the Atto 3 430 km or 510 km is the next step up. If they want a five-seat hatchback rather than an SUV, see BYD Dolphin vs Seagull. The Dolphin has the same motor trap: its range figure doesn’t tell you the motor either.

Shipping and paperwork

For Ethiopia, every car moves through the Port of Djibouti and then inland by rail or road. Under current rules, fully assembled EVs pay 15% customs duty with VAT, excise and surtax waived. Confirm the current rate with your clearing agent before you quote a landed cost.

At 4310 mm, the Atto 2 is compact enough to load efficiently in a container. See how many cars fit in a container and shipping routes to African ports.

Warranty is territorial. BYD’s Chinese warranty doesn’t automatically follow a car exported by an independent exporter. Agree after-sales terms with your customer before you sell. For supplier checks, see how to choose a Chinese car exporter.

FAQ

What versions of the BYD Atto 2 are there?

The 2025 China-market Atto 2 (Yuan UP) has three: 301 km with a 32 kWh battery and 70 kW motor, 401 km with a 45.12 kWh battery and 70 kW motor, and 401 km with the same battery and a 130 kW motor.

What is the difference between the 70 kW and 130 kW Atto 2?

Acceleration and equipment. The 130 kW version reaches 100 km/h in 7.9 seconds against 12.9 seconds, has 290 N·m of torque against 180, and BYD’s sheet lists curtain airbags only on the 130 kW version. Range is the same 401 km.

Is the BYD Yuan UP the same as the Atto 2?

Yes. Yuan UP is the China-market name and Atto 2 is the main export name for the same model.

Is the Atto 2 smaller than the Atto 3?

Yes. The Atto 2 is 4310 mm long on a 2620 mm wheelbase; the Atto 3 is 4455 mm on a 2720 mm wheelbase. They are different models in different size classes.

How fast does the Atto 2 charge?

All versions charge from 30% to 80% in about 30 minutes on DC. Peak DC power is 45 kW on the 301 km version and 65 kW on the 401 km versions.

Which Atto 2 should I import?

For most buyers, the 401 km / 130 kW version: same range as the cheaper 401 km car, much stronger acceleration, and curtain airbags. The 301 km version suits city-only buyers on the tightest budget.
