The 2026 BMW 4 Series story begins with the traditional Coupe. This is the model that stays true to its roots – a genuine two-door sports car with that classic design that turns heads everywhere you go. The entry point into 4 Series ownership starts with the 430i Coupe. This beauty packs a 2.0-liter BMW TwinPower Turbo inline 4-cylinder engine that pumps out 255 horsepower. You’ll hit 60 mph from a standstill in just 5.4 seconds.
Step up to the M440i with its 3.0-liter BMW M TwinPower Turbo inline 6-cylinder. This model produces 386 horsepower and reduces 0–60 time to just 4.2 seconds. Plus, BMW added 48V mild hybrid technology to boost efficiency and give you extra power right when you need it most. Both models offer BMW’s famous xDrive all-wheel drive system for maximum grip in any weather. Rear-wheel drive is also available for drivers who prefer a more traditional setup. 430i manages 36 mpg with rear-wheel drive and 34 mpg with xDrive. |
|---|---|
| Inside, you’re surrounded by luxury. The latest BMW Operating System 8.5 runs on the stunning BMW Curved Display – a 12.3-inch instrument cluster flows seamlessly into a 14.9-inch central screen. Even base models include features like a BMW Head-Up Display, the BMW Digital Key, and the BMW Intelligent Personal Assistant. | |
 |
Traditionally speaking, the word “Coupe” meant two doors. BMW decided to rewrite the rulebook with this model, proving you can have that coupe roofline and still make life easy for your rear passengers. You enjoy sporty styling with added practicality—no awkward backseat access required.
The 430i Gran Coupe shows off BMW’s recently redesigned kidney grille, which is finished in bold black paint. The gorgeous rear lights use high-precision laser technology for a distinctive look after dark. Rolling on dual-spoke wheels wrapped in BMW’s signature run-flat tires, this model makes a bold impression. |
|---|---|
| Step inside, and you’ll discover why it’s the roomiest gas-powered 4 Series. Five adults can ride in comfort with plenty of space for everyone. Your hands grip the sporty two-spoke steering wheel, and you can use the paddle shifters or switch to Manual mode. There’s even Launch Control for maximum acceleration! The ambient lighting system sets the perfect mood for any drive. Every surface feels premium, from the SensaTec upholstery to those eye-catching honeycomb air vents. Upgrade to Vernasca Leather with Red Highlights for extra sportiness. | |

The 4 Series Convertible allows you to take all that power and luxury and gives you an exciting option. When you want to make a real statement, nothing beats dropping the top and feeling the wind in your hair.
You’ll find the same powerful engine options here – the 430i and M440i convertibles deliver identical performance to their coupe siblings. Sure, they’re a tiny bit slower due to the convertible mechanics, but we’re talking milliseconds. The highlight is the power-retractable soft top, which opens in just 10 seconds – even while driving up to 30 mph! BMW engineered the soft top with integrated sound-dampening panels for less road noise and better insulation. |
|---|---|
| From the outside, the Convertible shares the Coupe and Grand Coupe’s athletic design. The curves look even better under the open sky, especially when rolling on 19-inch wheels. The My BMW App puts control at your fingertips – check your car’s status, plan routes, or even operate the roof remotely. | |
If you’re looking for an electric model in the 2026 BMW 4 Series, you have one fantastic option – the i4. This all-electric powerhouse has become BMW’s best-selling EV, and once you experience it, you’ll understand why.
Unlike traditional models, the i4 uses battery-electric power to deliver instant torque and near-silent acceleration.

i4.The BMW i4 specs show us how it sets itself apart by its pure electric power. The top-tier M50 trim delivers 536 horsepower that launches you from 0 to 60 mph in 3.7 seconds. This rocket uses dual BMW M eDrive motors working with xDrive all-wheel drive. Want something more affordable? The eDrive40 uses a single rear-mounted motor for 335 horsepower and a 5.5-second sprint to 60 mph. For those who miss that legendary engine sound, BMW IconicSounds Electric creates a soundtrack that matches your driving. The i4 takes the Gran Coupe form with four practical doors. Inside, comfort reigns supreme. You can even add glass controls that sparkle like diamonds! Home charging is simple with the BMW Flexible Fast Charger or Wallbox. The My BMW App helps find public charging stations. Expect around 300 miles of range with the eDrive40. |
|---|---|
| Two Energy Recuperation Modes control regenerative braking, sending energy back to the battery. The trunk includes clever storage compartments for charging gear. And the Augmented View display overlays navigation directions on a real-time camera view. | |
Now, we have reached the pinnacle – the M models created by BMW’s Motorsport division. These aren’t just quick—they’re precision-engineered machines built for the track and the road.
The M badge means serious business, and the following models are the quickest, most powerful vehicles in the entire 4 Series family.
