⚡ The short version
BMW's iX3 40 — the cheapest version of its new Neue Klasse electric SUV — makes its UK driving debut at SMMT Drive Live on 23–24 September, priced from £53,250 on the road. Rear-wheel drive, 320 hp, up to 395 miles of WLTP range and an 800-volt pack that adds up to 186 miles in 10 minutes. It undercuts the Mercedes-Benz GLC Electric and the Volvo EX60 on list price — but sits above the £50,000 Expensive Car Supplement threshold and far above the £37,000 cap on the Electric Car Grant.
Range figures are the easiest way to misjudge a new electric car. The numbers that actually decide whether it is worth buying are the price on the road, the charging curve and what the Treasury takes back afterwards.
What BMW has announced
On 16 September BMW Group UK confirmed that the BMW iX3 40 will make its UK driving debut at SMMT Drive Live on 23–24 September 2026 — the industry ride-and-drive event run by the Society of Motor Manufacturers and Traders.
The 40 is the second drivetrain variant of the fully electric Neue Klasse Sports Activity Vehicle and a new entry point to the iX3 range. It shares its styling and core technological innovations with the BMW iX3 50 xDrive, but combines rear-wheel drive with a single electric motor producing 320 hp and 500 Nm of torque.
The numbers that matter
- Price: from £53,250 on the road.
- Range: up to 395 miles on the WLTP combined cycle.
- Architecture: 800 volts, with DC charging at up to 300 kW.
- Charging: up to 186 miles added in 10 minutes; 10–80% in 21 minutes.
- Battery: an 82.6 kWh usable pack, according to RAC Drive's review.
- Technology: BMW Panoramic iDrive with Operating System X, and Motorway Assistant — hands-off Level 2 assisted driving on UK motorways that also lets the driver initiate a lane change by looking at the relevant exterior mirror.
BMW says standard specification is identical to the iX3 50 xDrive, so the 40 is a powertrain choice rather than a stripped-out fleet special.
Why 800 volts and 395 miles is the real story
The previous-generation iX3 promised up to 285 miles on a charge. The new entry model promises 395 — and, as RAC Drive notes, it does so at a starting price below the car it replaces. That is the Neue Klasse platform doing its job.
The more interesting figure is the 10-minute one. Adding 186 miles in the time it takes to buy a coffee only works because an 800-volt architecture keeps the charging curve high without needing an enormous battery. At 82.6 kWh usable, the iX3 40's pack is not unusually large — the car is simply efficient enough to go a long way on it. Top Gear's long-term test of the iX3 50 xDrive backs that up: on a 260-mile trip it arrived with around 40% still in the battery, and the magazine puts usable range past 400 miles.
The caveat is cost, not capability. A 300 kW charger is the most expensive electricity on the network, so 186 miles in 10 minutes is a convenience purchase. Our charging cost calculator shows what that top-up costs against charging at home overnight — the difference is large enough to change how you plan journeys.
The full iX3 price ladder
| Variant | Price from |
|---|---|
| BMW iX3 40 | £53,250 |
| BMW iX3 40 M Sport | £55,750 |
| BMW iX3 40 M Sport Pro | £57,250 |
| BMW iX3 50 xDrive | £60,655 |
| BMW iX3 50 xDrive M Sport | £61,255 |
The M Sport upgrade adds £2,500 to the 40 and is mostly styling and interior trim. RAC puts the top of the iX3 range at around £64,000 in 50 xDrive M Sport Pro form. Every version uses the same Neue Klasse display and operating concept, so the cheapest car in the range does not feel like a different generation. RAC also notes the iX3's starting price is slightly lower than the Mercedes-Benz GLC Electric and the Volvo EX60, while a Tesla Model Y Long Range All-Wheel Drive undercuts it. You can line up those numbers in our electric car library, or put two models head-to-head on price, range and charging with the car comparison tool.
The two UK tax catches
1. No grant. The £3,750 Electric Car Grant is capped at a £37,000 list price on eligible models, so nothing in the iX3 range qualifies. If the grant is part of your budget, our guide to every UK EV grant and incentive you can actually claim sets out what does.
2. The £50,000 road-tax line. From 1 April 2026 the Expensive Car Supplement threshold for zero-emission cars rose from £40,000 to £50,000. Cars above it pay an extra £440 a year from year two to year six of registration, on top of the standard £200 EV rate — roughly £640 a year in total. At £53,250 the iX3 40 clears that threshold. Our EV road tax guide explains the bands, and the road tax calculator gives the exact figure for any list price and registration date.
Take the car through a company instead of buying it privately and the picture reverses. A zero-emission company car carries a Benefit-in-Kind rate of just 4% in 2026/27. Our guide to electric company car tax and BIK rates works through the numbers.
The rest of the BMW and MINI line-up at SMMT Drive Live
BMW is also bringing the i7 50 xDrive (from £104,230, up to 452 miles), the i7 M70 xDrive (from £164,420), the MINI Cooper Electric Paul Smith Edition (from £32,705) and the MINI Countryman Electric (from £33,005, up to 307 miles after technical updates including a new silicon carbide inverter). The contrast is worth sitting with: BMW's cheapest electric SUV is a £53,250 car that misses the grant and triggers the expensive-car supplement, while the Countryman E at £33,005 collects the full £3,750 and stays under the £50,000 line. In the UK market of 2026, the tax treatment of an electric car depends far more on its list price than on whether it plugs in.
What this means for UK buyers
Range is no longer the constraint. A 395-mile WLTP figure from a sub-£55,000 premium SUV means the practical question has shifted to charging speed and charging cost, especially for anyone without a driveway. And when the iX3 40 reaches customers, 300 kW charging stops being an exclusive feature of six-figure cars — competition keeps working in buyers' favour, as our analysis of why Britain refuses to match EU tariffs on Chinese cars explains.
Tax positioning matters as much as efficiency. Two cars with identical running costs can differ by £640 a year in VED, and by £3,750 in grant, purely because of where the list price falls.
The bottom line
The iX3 40 is the most consequential car BMW has put on a UK price list this year: 395 miles, an 800-volt pack, 10-minute top-ups and a starting price below the model it replaced. The compromises are not in the technology; they are in the tax code. Buy it privately and you pay the £50,000 supplement; buy it through a company and you access the lowest BIK rate on the market.
