Additionally, we offer an overview of the full specifications, an image gallery, detailed information about charging performance, and some online reviews. Our sections include:

Performance

The BMW i3s 120 Ah has a maximum power of 135 kW (184 hp / 181 bhp) and a total torque of 270 Nm (199 lb-ft). It accelerates from 0 to 100 km/h (0 to 62 mph) in 6.9 seconds and reaches a top speed of 160 km/h (99 mph).

Battery, Range, and Charging

The high-capacity battery has a gross capacity of 42.2 kWh and a net usable capacity of 37.9 kWh, providing a 4.3 kWh buffer (10.2%) for battery protection. With a nominal voltage of 352 volts, the system is classified as a 400-volt battery system, aligning with industry standards.

This Lithium-Ion battery utilizes NMC (Nickel Manganese Cobalt) technology.

Under the WLTP (Worldwide Harmonized Light Vehicles Test Procedure) standard, the vehicle's range varies between 285 to 270 km (177-168 miles), depending on the specific configuration and options, such as wheel size. Larger wheels can increase energy consumption and subsequently reduce the overall range.

The vehicle's energy consumption is rated at 13.3 kWh/100 km for the base model and 14.0 kWh/100 km for the top-tier model under the WLTP test cycle.

For more details about the range, see real-world data and range listings on this model’s range and consumption page.

The vehicle supports fast DC charging with a maximum power of 50 kW. Charging from 0% to 100% takes approximately 69 minutes, while a typical 10% to 80% charge takes about 38 minutes with an average charging speed of 42 kW.

Considering an additional 5 minutes for each charging stop due to driving interruptions, the optimal charging range is from 2% to 86%. This results in an effective charging speed, including time lost, of 38 kW, with each charging session taking about 50 minutes and 8 seconds.

In a 1000 km challenge at a constant speed of 120 km/h (75 mph) with an assumed consumption rate of 20 kWh/100 km, the trip would take about 12 hours and 37 minutes, needing five charging stops from 1% to 87%, totaling 257 minutes of charging time.

Onboard Charger

The standard onboard charger supports up to 7.2 kW for Level 1 and Level 2 AC charging, allowing a full 0–100% charge in about 5 hours and 15 minutes with a standard home setup.

An optional 11 kW onboard charger reduces the full charge time to approximately 3 hours and 26 minutes.

Charge Port

The location of the charge port is on the right rear side. This placement makes it easy to use charging stations that require backing up to connect.

Connector types vary by market: this model uses CCS Combo 1 in North America and CCS Combo 2 in Europe. For complete specifications for all markets, refer to the full specifications.
