2026 BMW 4 SERIES
WHAT'S NEW, MODELS, SPECS & FEATURES.
The 2026 BMW 4 Series adds standard wireless charging to every trim, a meaningful upgrade from the prior model year. The 48V mild-hybrid system now pairs with both the 255 hp 430i four-cylinder and the 386 hp M440i six-cylinder. This page covers every trim, body style, and spec, plus current inventory at Grayson BMW in Knoxville.
WHAT'S NEW FOR 2026.
The most notable change for 2026 is the addition of standard wireless charging across the entire BMW 4 Series lineup, a feature that previously required an option package. Every coupe, Gran Coupe, and convertible now leaves the factory with it fitted.
The 48V mild-hybrid system is integrated on both the 430i and M440i powertrains. The belt-mounted starter-generator assists during acceleration, smooths the stop-start function, and recovers energy under braking. It does not enable all-electric driving, but it does improve throttle response and efficiency across the range.
BMW Operating System 8.5 carries forward with the BMW Curved Display as standard equipment. The system includes five USB-C ports front and rear, a BMW Digital Key Plus with Ultra-Wideband spatial awareness, and over-the-air software update capability. The full technology stack is available regardless of which body style or powertrain a buyer chooses.
The 2026 lineup spans 12 total model variants: four powertrain configurations across three body styles (Coupe, Gran Coupe, Convertible), with rear-wheel drive or xDrive AWD available on every one.
Model LINEUP.
The 2026 BMW 4 Series starts at the 430i Coupe. Eight configurations are shown below, with Gran Coupe variants adding a fourth body-style option.
BMW 430i Coupe / 430i xDrive Coupe
The entry point to the lineup. Standard equipment includes the BMW Curved Display with a 14.9-inch touchscreen, heated front sport seats, dual-zone automatic climate control, a flat-bottom M Sport leather steering wheel, multi-color ambient interior lighting, active safety suite, and wireless Apple CarPlay and Android Auto. The 430i xDrive Coupe adds BMW's intelligent AWD.
BMW 430i Convertible / 430i xDrive Convertible
The soft-top convertible adds an insulated multi-layer fabric roof that raises and lowers in approximately 10 seconds at speeds up to 30 mph. A Wind Deflector is standard. The optional Neck Warmer delivers heated airflow at the headrest level for open-air driving in cooler weather.
BMW M440i Coupe / M440i xDrive Coupe
The M440i steps up to the 3.0L M TwinPower Turbo inline six-cylinder producing 386 hp and 398 lb-ft of torque. M Sport suspension is standard, as are M Sport brakes with blue-painted calipers, a torque-vectoring M Sport Differential, 19-inch M Sport alloy wheels, quad exhaust outlets, M Sport seats with M stitching, and illuminated M door sill plates. The M440i xDrive Coupe covers 0-60 mph in 3.6 seconds.
BMW M440i Convertible / M440i xDrive Convertible
All M440i performance equipment carries into the convertible body. The M440i Convertible represents the most open-air performance variant in the lineup.
Option packages available across the lineup include the Premium Package (Harman Kardon 16-speaker audio, remote engine start, heated steering wheel, Live Cockpit Professional navigation), the Driving Assistance Professional Package, the Parking Assistance Package with 360-degree SurroundView, Adaptive M Suspension, Bowers and Wilkins Diamond Surround Sound (1,500W+), and Glass Controls for the center console.
PERFORMANCE & POWERTRAIN.
| Model. | Engine. | Power. | Torque. | 0–60 mph. | EPA Fuel Economy. | Top Speed. |
|---|---|---|---|---|---|---|
| 430i | 2.0L TwinPower Turbo four-cylinder with 48V mild hybrid | 255 hp @ 5,000–6,500 rpm | 295 lb-ft @ 1,550–4,400 rpm | Approx. 5.5 sec RWD; approx. 5.0 sec xDrive | RWD: 28 city / 36 highway / 30 combined mpg; xDrive: 27 city / 35 highway / 29 combined mpg | Not specified |
| M440i | 3.0L M TwinPower Turbo inline six-cylinder with 48V mild hybrid | 386 hp @ 5,800–6,500 rpm | 398 lb-ft @ 1,800–5,000 rpm | 4.2 sec RWD; 3.6 sec xDrive | RWD: 26 city / 32 highway / 28 combined mpg | 130 mph standard; 155 mph with performance tires |
Both engines use an 8-speed sport automatic transmission. Standard top speed is 130 mph on both variants; the 155 mph figure requires performance tire fitment. Premium unleaded fuel (91+ octane) is required. Fuel tank capacity is approximately 15.6 gallons across all configurations.
The xDrive all-wheel-drive system distributes torque variably front to rear, integrating with Dynamic Stability Control and the M Sport Differential. It is available on all models and body styles above the rear-wheel-drive equivalent.
The M Sport Differential on the M440i actively vectors torque between the rear wheels during cornering. It is optional on the 430i.

INTERIOR, COMFORT & CARGO.
All 2026 BMW 4 Series models start with SensaTec premium synthetic upholstery, heated power front sport seats with four-way lumbar and driver memory, dual-zone automatic climate control, an anthracite headliner, auto-dimming rearview mirror, and multi-color adjustable ambient interior lighting.
Vernasca leather is available across multiple seat colors including Canberra Beige, Cognac, and Tacora Red. Ventilated and massage front seats are available as a standalone option.
The three body styles differ in practical terms:
- Coupe:
Two doors, four passengers, 10.6 cu ft of conventional trunk space. The sleek fastback roofline and frameless windows define the sportiest silhouette in the lineup. A panoramic sunroof is standard. - Gran Coupe:
Four doors, five passengers, 16.6 cu ft of cargo space with seats up, and 45.6 cu ft with the 40/20/40 split-folding rear seatbacks lowered. The power liftback replaces a conventional trunk lid. This is the most practical body style in the lineup and the only one with five-seat capacity. A panoramic sunroof is standard. - Convertible:
Two doors, four passengers, 10.6 cu ft of trunk space with the top up and approximately 8.0 cu ft with it down. The insulated multi-layer fabric soft top reduces wind and road noise when closed.
The M440i adds M Sport seats with enhanced lateral support and M stitching, an M leather steering wheel with M-color stitching, aluminum door sills, and illuminated M door sill plates as standard interior content.

WHO IT'S FOR VS. THE PRIOR YEAR.
The 2026 BMW 4 Series is the right choice for drivers who want a two-door (or four-door Gran Coupe) performance vehicle with a full modern technology stack and genuine open-top or sport coupe character. The standard wireless charging, 48V mild-hybrid integration across all powertrains, and BMW OS 8.5 place it ahead of where the prior model year stood on day-to-day usability.
Buyers deciding between the 430i and M440i face a real question. The 430i delivers a 30 mpg combined EPA estimate, the full tech stack, and xDrive availability, making it the stronger everyday vehicle. The M440i adds 131 horsepower, a standard torque-vectoring differential, M Sport suspension, M brakes, and a more aggressive presence inside and out. The M440i xDrive Coupe reaches 60 mph in 3.6 seconds.
For Knoxville-area drivers, Grayson BMW carries both coupe and Gran Coupe body styles in inventory. The Gran Coupe is worth a closer look for anyone who regularly carries rear passengers or needs more cargo room without moving up to an SUV.
