After launching the 4 Series Coupe back in June, BMW has now unveiled the all-new BMW 4 Series Convertible. With a blend of driving pleasure and open-air thrills, the new 4 Series Convertible builds on a long-standing tradition in this model class that began 35 years ago with the launch of the first-ever BMW 3 Series Convertible.
The 4 Series Convertible’s elegant yet muscular presence comes from its larger exterior dimensions. In terms of length, the 4 Series Convertible measures at 4,768 mm, 123 mm longer than it’s predecessor, while width has increased by 27 mm to 1,852 mm.
The wheelbase of the 4 Series Convertible has also increased by 47mm to 2,851 mm. Height of the car is 1,384 mm with the roof up, and track width is increased by 28 mm in the front and 18 mm at the rear.
In terms of engines, the 4 Series Convertible is powered by petrol and diesel engine options; the 2.0-litre petrol-powered engine generates 184 hp and 300 Nm in the new BMW 420i Convertible. The same petrol mill found in the BMW 430i Convertible, however, generates 258 hp and 400 Nm.
For the diesel option, there is a four-cylinder diesel engine that’s found on the BMW 420d Convertible putting out 190 hp and 400 Nm whereas, the 430d Convertible gets a six-cylinder diesel engine that puts out a healthy 286 hp and 650 Nm.
The 4 Series Convertible also has a mild hybrid variant that comes in the form of the BMW M440i xDrive Convertible. The engine powering this can be had in either petrol or diesel. The six-cylinder petrol engine will put out 374 hp and 500 Nm while the six-cylinder diesel engine will churn out 340 hp and 700 Nm.
This is the first time that all model variants in the BMW 4 Series Convertible range are fitted with an eight-speed Steptronic transmission as standard.
The 4 Series Convertible comes with a sophisticated and innovative panel bow soft-top. It marries the strengths of a retractable hardtop and the purist appeal of a fabric roof, thereby combining the best of both worlds.
Despite comprising of a large panel bow elements with a flush-fitting glass rear window, several layers of insulation and a fabric cover, the 4 Series Convertible’s soft-top is actually 40% lighter than it’s predecessor’s hard-top. The soft-top is available in black as standard, but customers can opt for the Anthracite Silver as an option.
The roof of the 4 Series Convertible is powered by an electric motor that allows it to open or close within 18 seconds at the push of a button. On the move, the retractable soft-top can operate at speeds of up to 50 km/h.
BMW also very recently unveiled the new BMW M3 and BMW M4, with the BMW M3 makes 480 hp and 550 Nm from a 3.0-litre turbocharged straight-six engine. The BMW M4 on the other hand is powered by the S58 3.0-litre twin-turbocharged inline-six engine with 473 hp and 550 Nm for the standard and 503 hp and 650 Nm for the higher-tuned Competition specification.
