2026 BMW 420i Convertible Automatic

2026 BMW 420i Convertible 420i.

The 2026 BMW 420i Convertible combines the open-air appeal of a four-seat convertible with the measured performance and technology expected from BMW's 4 Series family. Finished in Gray Dark with a Black interior, it presents as a new vehicle with delivery mileage only and a specification aimed at making everyday driving more comfortable, connected and engaging.

Its 135 kW petrol engine produces 300Nm of torque and is paired with an automatic transmission driving the rear wheels. The setup is suited to relaxed cruising as well as more involved driving, while the listed combined fuel consumption of 6.6L/100km provides useful efficiency context for a performance-oriented convertible. BMW quotes a top speed of 236 km/h and a 0-100km/h time of 8.20 seconds.

The convertible format gives the 420i a distinct lifestyle advantage. With seating for four, it can accommodate more than two occupants, while the retractable roof allows the cabin environment to change with the weather and the occasion. An air collar and wind deflector are specified to help make open-top travel more comfortable, and heated front seats, a heated steering wheel and automatic air conditioning add useful year-round convenience.

The M Sport equipment brings a more purposeful visual and tactile character through an M leather steering wheel, M Aerodynamics package, M interior trim in Fine-Brushed Aluminium and a luxury instrument panel. The listed Black Vernasca leather upholstery with contrasting blue stitching adds a tailored finish to the cabin, while M High-Gloss Shadow Line detailing sharpens the exterior presentation.

Technology is supported by BMW Live Cockpit Professional, Connected Package Professional, a personal eSIM and DAB+ radio. The Harman Kardon Surround Sound System is included within the Enhancement Package, providing a stronger audio focus for longer journeys or open-road touring. Wireless Charging Storage and Comfort Access System further reduce everyday friction, while lumbar support for the driver and front passenger adds additional adjustment for longer periods behind the wheel.

Driver assistance and convenience equipment includes Parking Assistant Plus, Adaptive LED headlights, High-Beam Assistant, an Exterior Mirror Package and an interior rear-view mirror with automatic anti-dazzle function. Active Guard Plus, Active Protection, Active Pedestrian Protection and Intelligent Emergency Calling contribute to the vehicle's broader safety and monitoring specification. The Sports automatic Steptronic transmission, variable sport steering and tyre-pressure monitoring round out a package that balances usability with a more dynamic character.
