The New BMW i3 Goes 900km. Make Sure Its Wi-Fi Keeps Up.
The new BMW i3 pairs 900km of WLTP range with 400kW charging. Add a BMW Personal eSIM from Xtreme+, and you get unlimited 5G in-car Wi-Fi, too, no phone hotspot required.
For a decade, buying an electric car meant doing arithmetic in your head. How far to the next charger? Will it be working? The new BMW i3 quietly deletes that maths, and it does it with numbers that would have sounded like marketing fiction three years ago.
BMW revived the i3 badge in March 2026, but forget the quirky 2013 hatchback. The BMW i3 2026 is a full electric sports sedan, the second BMW Neue Klasse model after the iX3, and the car BMW openly describes as the first member of the next-generation 3 Series family.
This guide breaks down the BMW i3 specifications, range, battery, charging speed, and how it stacks up against a Tesla Model 3. Then we cover the part most owners only discover after delivery: how to get proper unlimited 5G in-car WiFi in a BMW, without draining your phone.
What Is the New BMW i3 and Why Does It Matter?
The BMW i3 electric sedan is built on the Neue Klasse architecture, a platform engineered for EVs from the ground up rather than adapted from a combustion car. That single decision explains almost everything that follows, from the range figure to the charging speed.
At 4,760mm long with a 2,897mm wheelbase, this next-generation BMW EV is slightly larger than the outgoing G20 3 Series. It uses what BMW calls a "2.5-box" profile: sleeker than a traditional saloon, with a shark-nose front end, slim illuminated kidney grilles, and wheels pushed right to the corners for a wider stance.
What Changes Inside the BMW i3?
The dashboard, essentially. BMW Panoramic Vision projects driving information across the base of the windscreen, the same pillar-to-pillar strip this page borrows for its header, paired with a 17.9-inch angled central display running BMW Operating System X and a generative AI voice assistant. It is a genuinely intelligent connected vehicle, and one that treats mobile data as a core ingredient rather than an accessory.
That matters more than it sounds. An always-connected BMW running over-the-air updates, 60+ apps, streaming services, and an LLM assistant needs a data connection that doesn't run out halfway through a road trip. We come back to that below.
BMW isn't experimenting anymore. It's committing. The i3 is a reinterpretation of BMW's core idea a compact, driver-oriented sports sedan, now translated into an electric future.
Industry consensus following the Munich world premiere
BMW i3 Range, Battery and Charging Speed
Three figures define the BMW i3 50 xDrive, the launch variant. Everything else is detail.
900km WLTP
Up to 900km on the WLTP cycle — roughly 440 miles under EPA test procedures, and about 95km more than the iX3.
400kW Peak
BMW 400kW charging adds up to 400km of range in ten minutes on a matching ultra-rapid DC charger.
463hp Dual Motor
463hp and 476 lb-ft from two motors, all-wheel drive, on an 800-volt BMW eDrive technology platform.
BMW i3 900km Range Explained: Is It Realistic?
Where Does the Extra Range Come From?
Three things, mostly, and none of them are magic:
- Aerodynamics. A sedan body slips through the air better than the iX3 crossover, which already manages a 0.24 drag coefficient.
- New cells. BMW moved from prismatic to cylindrical BMW i3 battery cells, lifting energy density by around 20% and charging speed by roughly 30%.
- Efficiency. The Gen6 motors are lighter, more compact, and better thermally managed than the outgoing generation.
WLTP is a laboratory cycle, not a promise. Motorway cruising at 120km/h in February will pull the number down. Even so, a genuine 400-mile long-range electric vehicle in this class is a first, and it's why the i3 is being treated as a milestone rather than a facelift.
BMW i3 400kW Charging Speed: How Long Does It Take?
There is a caveat worth being honest about: you need a charger capable of delivering 400kW, and those remain uncommon outside major corridors. On a more typical 150kW unit, you will still charge quickly, just not headline-quickly.
| Charger type | Power | BMW i3 charging time |
|---|---|---|
| Ultra-rapid DC | 400 kW | ~400km added in 10 minutes |
| Rapid DC | 150 kW | 10–80% in roughly 40–50 minutes |
| Home wallbox | 11 kW AC | Full charge overnight |
| Bidirectional (V2H / V2G) | — | Car powers your home or supports the grid |
Bidirectional charging deserves its own mention. Vehicle-to-Home and Vehicle-to-Grid effectively turn the i3 into a power bank on wheels, useful during an outage, and potentially profitable if your energy tariff rewards grid support. North American cars also ship with a native NACS port, so Tesla Superchargers are on the table from day one.

BMW i3 vs Tesla Model 3: Which Should You Choose?
It is the comparison everyone makes, and fairly so. The Model 3 defined this segment. The i3 is the first premium German answer that doesn't feel like a compromise.
| BMW i3 50 xDrive | Tesla Model 3 Long Range | |
|---|---|---|
| Headline range | Up to 900km WLTP | Around 700km WLTP |
| Peak charging | 400 kW | Around 250 kW |
| Architecture | 800V | 400V |
| Bidirectional | V2H and V2G | Limited |
| Charging network | NACS port, Supercharger access | Native Supercharger |
| Price | Est.$50,000–$55,000 | Lower |
If you cover long distances and care about cabin quality, the i3 makes a compelling case as a premium electric sedan. If value per kilometre is your priority, the Model 3 remains hard to beat. Tesla's software maturity is real, but the i3's native NACS port neutralises the network advantage that used to settle this argument.
Why the BMW i3 Needs More Than Its Built-In Data
Here is what most i3 buyers discover about a week after delivery. The car has a spectacular screen, 60+ apps, streaming services, and even Zoom for calls. All of it runs on data, and BMW's bundled allowance disappears faster than you'd expect once passengers start streaming on a long drive.
This is not unique to the i3. It's the trade-off of every BMW connected car: the more the vehicle can do, the more data it quietly needs. Owners who follow BMW's software releases will already recognise the pattern: each BMW Summer Update adds more connected features, more apps, and more reasons for the car to be online.
The fix is a BMW Personal eSIM. It gives your BMW its own mobile data connection, completely separate from your phone. Xtreme+ appears as a network provider directly inside the My BMW App, which means no third-party hardware, no dongles, and no physical SIM card.
A phone hotspot drains your battery, eats your personal allowance, and disconnects the moment you leave the car. A BMW personal eSIM lives in the vehicle and uses the car's roof antennas, which routinely pull a stronger 5G signal than a phone in your pocket. Passengers connect to the car, not to you.

Is the New BMW i3 Worth Buying?
The new BMW i3 solves the two problems that kept sensible people out of electric cars: range and charging time. 900km and a ten-minute top-up aren't incremental gains; they're the point at which an EV simply stops being a compromise. Add the Heart of Joy control unit, which responds ten times faster than previous systems, and BMW appears to have protected the thing that made a 3 Series a 3 Series.
But a car this connected is only as good as its connection. The Panoramic display, the app ecosystem, the AI assistant, and the passengers in the back, all of it runs on data. Sort that out on day one, and the i3 becomes exactly what BMW intends it to be: a car you never have to think about.
