BMW Adds M340i and M440i Black Editions for Summer 2026 From £66,475

BMW is using its summer 2026 model-year update to give the M Performance 3 Series and 4 Series families a darker, more focused look, introduce a fuel-saving ignition system across its M six-cylinder cars, and add nine BMW Individual paint colours plus heated rear seats to the electric iX3. UK pricing for the new M340i xDrive Black Edition starts at £66,475 OTR, with the M440i xDrive Gran Coupé Black Edition opening at £68,610 OTR.

Owners shopping the current 3 Series and 4 Series ranges now have a halo trim short of an outright M3 or M4, with carbon fibre interior details, black exterior badging and 19in M alloy wheels in Jet Black included as standard. Buyers of any M3, M4 or M2 will also benefit from the fuel-saving BMW M Ignite system from July 2026 (August for the M2), and BMW iX3 customers will be able to pick from an expanded palette and a properly winter-friendly heated rear bench. Here is what each change involves and what it means for the cars on UK forecourts this summer.

Black Edition Brings Carbon Trim and Red M Brakes to the M340i and M440i

The new Black Edition trim is offered on the BMW M340i xDrive Saloon, M340i xDrive Touring and M440i xDrive Gran Coupé. It is bundled exclusively with the M Sport package Pro, which means M Sport brakes finished in red, along with motorsport-style cabin details that will be familiar to anyone who has specced a higher M car. Inside, the carbon fibre M interior trim is joined by an M leather steering wheel with carbon decorative trim, while the cabin is finished off with sportier graphics on the digital dials and head-up display.

Outside, the changes are aimed at owners who want their car to look quietly meaner rather than louder. Black model badges replace the chrome lettering on the rear and sides, and 19in M light-alloy wheels are finished in Jet Black with mixed tyres. The M340i xDrive Saloon and Touring use BMW’s 995 M wheel design, while the M440i xDrive Gran Coupé adds an extra black model badge in the kidney grille and rides on the 861 M 19in design. These M light alloy wheels are also being released as an individual option for the rest of the 4 Series M Performance line-up, including the 4 Series Coupé and 4 Series Convertible, optionally with sport tyres.

Pricing makes the Black Edition a relatively small step up from the regular M Sport Pro derivatives but a long way short of the M3 Competition’s six-figure ticket. The M340i xDrive Saloon Black Edition opens at £66,475 OTR, the M340i xDrive Touring at £68,315 OTR, and the M440i xDrive Gran Coupé Black Edition at £68,610 OTR. WLTP combined figures sit at 7.8 l/100 km and 176 g/km CO2 for the M340i, and 7.9 l/100 km and 179 g/km CO2 for the M440i Gran Coupé, so the cost-of-ownership story is unchanged.

For drivers cross-shopping the Audi S4 successor and the Mercedes-AMG C 43, the BMW pitch is a sharper visual identity than either German rival without forcing buyers into a full-fat M car. With the M Sport Pro package included, the Black Edition also pulls forward kit such as red brake calipers, an M Sport differential on the M340i and adaptive M suspension, which are typically expensive ticks on the options sheet.

BMW iX3 Adds Nine Colours, Heated Rear Seats and 21in M Aero Wheels

The Neue Klasse electric iX3 has only been with us a matter of months, but the summer 2026 update is already widening its customisation menu. From this summer, UK iX3 buyers can choose from nine BMW Individual exterior paint finishes: Orinoco, Sepang Bronze, Twilight Purple, Grigio Telesto, Java Green II, Purple Silk Malachite Green, Voodoo Blue and Urban Green sit alongside the existing palette. New 1051 M 21in M Aerodynamic wheels in Jet Black join the wheel list, along with a Contemporary Agave bicolour interior design.

The most useful real-world upgrade for British buyers, though, is heated rear seats. These will be available in conjunction with the optional Innovation package and arrive at a point where family EV buyers are increasingly questioning why a car costing well into five figures should leave back-seat passengers reaching for blankets. Pair that with the iX3’s already-warm cabin tech, and the iX3 50 xDrive looks sharper as a family proposition against the Mercedes-Benz EQE SUV and the Audi Q6 e-tron.

BMW M Ignite: Pre-Chamber Tech From Motorsport Joins the M3, M4 and M2

The headline mechanical change is the introduction of BMW M Ignite, a patented pre-chamber ignition system for petrol engines that BMW has lifted from its motorsport programme. The technology fires combustion through a small antechamber before reaching the main cylinder, which produces a faster, more complete burn. BMW says the result is a significant reduction in fuel consumption under high loads and a much cleaner combustion process, helping the company meet the tighter Euro 7 emissions standard without resorting to downsizing or hybridisation.

All BMW M six-cylinder in-line engines pick up M Ignite from summer 2026, which means every M3 and M4 variant gets it from July 2026, with the M2 following from August 2026. Crucially, displacement and power outputs are not changing. The M2 keeps its 480PS 3.0-litre straight six, the M3 Competition stays at 530PS, and the M4 Competition xDrive carries on with 530PS. For owners, the headline benefit is reduced fuel use on long autobahn-style stints and during track work, where the existing engines are notoriously thirsty. There is no decontenting or character change to balance against the gain.

Tyre Repair Kit Plus, M Stripe Car Keys and New In-Car Routines

The summer update also rolls in a series of smaller equipment changes that will affect a broader slice of BMW buyers. From summer 2026, the BMW 2 Series Coupé, 4 Series Coupé and 4 Series Convertible come fitted with the Tyre Repair Kit Plus, BMW’s seal-and-drive solution, as standard. That is a practical change for buyers who have previously had to rely on a run-flat tyre or hope a breakdown service can reach them on a Sunday afternoon. All BMW X3 models specified with the M Sport package or M Sport Pro Package will also now come with key fobs carrying the famous M tri-colour stripes, a small detail but a welcome one for owners who want the M look extending right down to what is in their pocket.

From July 2026, BMW Operating System X also opens up new options for creating routines inside the BMW Intelligent Personal Assistant. The Assistant analyses how owners use their car day to day and proposes routines: a school-run sequence that auto-loads a destination, warms the seats and queues a podcast, for example. Owners can also build their own routines from scratch, picking the trigger conditions and the actions they want the car to perform automatically. It is a small but useful step in BMW’s effort to make the in-car software feel less like a menu system and more like a personal driving assistant.

When You Can Order and What it Means for UK Buyers

UK order books open across the summer, with M3, M4 and M340i / M440i Black Edition production aligning with the July and August roll-out dates for M Ignite and the new trim. Heated rear seats, the new iX3 colour palette and the 21in M Aerodynamic wheels become available in the same window for iX3 customers, who can specify them through the existing online configurator and through dealers. For anyone already weighing up an M Performance 3 Series or 4 Series, the Black Edition arrives as the natural step up: it delivers the sharper visual identity buyers have been quietly asking for, while M Ignite means the M cars themselves stay relevant under the next round of European emissions rules.
