2026 BMW 420i Convertible Automatic

2026 BMW 420i Convertible 420i.

The 2026 BMW 420i Convertible combines the elegant proportions of a grand touring convertible with the focused, driver-oriented character expected of a BMW. With four seats, rear-wheel drive and a petrol engine producing 135 kW and 300Nm, it is configured for open-air motoring without giving up the practicality of occasional rear-seat use.

Its convertible body is the defining attraction. The format brings a more involving connection with the surroundings when conditions allow, while the restrained Mineral White exterior gives the car a clean, contemporary appearance. Black interior trim provides a contrasting cabin treatment, and the specification includes heated front seats, a heated steering wheel and automatic air conditioning to help maintain comfort across changing weather.

Power comes from a petrol drivetrain paired with an automatic transmission. The listed combined fuel consumption is 6.6L/100km, offering useful context for a car designed to cover both relaxed touring and everyday driving. Rear-wheel drive remains an important part of the 420i's traditional layout, while variable sport steering is included to support a more responsive feel through changing corners and urban manoeuvres.

The cabin is equipped for connected travel, with Connected Package Professional, BMW Live Cockpit Professional and a personal eSIM included in the specification. DAB+ radio, TeleServices and intelligent emergency calling add further support for communication and infotainment, while wireless charging storage helps keep compatible devices ready for use. Comfort Access, lumbar support for the driver and front passenger, and an automatic anti-dazzle interior mirror add practical polish to the daily experience.

Open-top touring is supported by equipment specific to the convertible format, including an Air Collar and wind deflector. These features are intended to make roof-down travel more comfortable by helping manage airflow around the occupants. The car also features ambient lighting, galvanic embellishment for the controls and a Fine-Brushed Aluminium interior finish, giving the cabin a more tailored atmosphere.

The listed equipment has a strong sporting emphasis. M Sport elements include an M leather steering wheel, M Aerodynamics package, M interior decor, M seat belts and sports automatic transmission with Steptronic. The M Sport Package Pro specification adds details such as M Lights Shadow Line, extended high-gloss Shadow Line treatment, red high-gloss M Sport brakes and adaptive LED headlights. Black Vernasca leather with contrasting blue stitching is also listed among the equipment, complementing the exterior and the car's performance-oriented presentation.

Driver assistance and parking support are well represented. Parking Assistant Plus, Active Guard Plus, Active Protection, Active Pedestrian Protection, High-Beam Assistant and a tyre pressure monitor are included in the listed specification. Together with the exterior mirror package, rear-view mirror anti-dazzle function and anti-theft security system, these features are aimed at reducing the effort involved in routine driving while adding reassurance on longer journeys.

As a new vehicle with zero kilometres, this 420i Convertible presents the current specification in a distinctive four-seat open-air format. Its appeal lies in the combination of convertible design, rear-wheel-drive dynamics, technology-focused equipment and everyday comfort, making it a clearly differentiated member of the 4 Series range.

Other highlights include Odometer: 0 km; Drive train: Rear Wheel Drive; Engine or motor: 135 kW (184 hp), 300Nm; Exterior colour: Mineral White metalic.
