The new design language introduced with the BMW 4 Series Coupe is even more evident in the drop top while setting new standards in terms of dynamics, elegance and driving pleasure. The new 4 Series Convertible is visibly larger in width, track and wheelbase than its preceding model while striking design features like the double-kidney grille, twin circular headlights and the large air intakes - are keen to display this convertible's family ties with the BMW 3 Series.
The interior roof is fully lined and features lamps that add to the ambience expected of a premium sport coupe while the low and sporty seats ensure more headroom and rear legroom.
Three specially equipped lines - sport, modern and luxury - along with an M Sport package are also available in addition to the base model.
Available from launch are a six-cylinder in-line petrol engine for the 435i, a four-cylinder petrol unit for the 428i Convertible and a four-cylinder diesel for the 420d, featuring the latest BMW TwinPower Turbo technology.
The power unit blend outstanding acceleration and elasticity while intelligently reducing fuel consumption in compliance with the EU6 standard. The power is sent to the rear wheels via a six-speed manual gearbox as standard while an optional eight-speed Sports automatic transmission is available as an option. Drivers can change gears manually via paddle shifter on the steering wheel for the latter.
Both transmissions are equipped with the Auto Start Stop function as standard. A coasting mode decouples the powertrain as soon as the driver backs off the accelerator at speeds between 50 and 160km/h.
In the 435i - the 3.0-litre engine develops a maximum output of 306bhp with peak torque of 400Nm, allowing it to accelerate to 100km/h in 5.6 seconds on the way to an electronically limited 250km/h top speed.
Average fuel consumption is between 8.1 and 8.4L/100km while emitting up to 195g/km of CO2. The 435i is even more economical when fitted with the optional eight-speed Sports automatic gearbox, achieving a combined fuel consumption of up to 7.7L/100km while emitting up to 180 grams of CO2/km.
The 2.0-litre four-cylinder in the 428i, generates 245bhp and 350Nm for a sprint to 100 km/h in 6.4 seconds and has an electronically limited top speed of 250 km/h.

Even with the hard-top lowered, the convertible offers decent amount of space in the boot. Unlike earlier models, the new convertible offers wider access to the luggage compartment as an electro-hydraulic loading assistance system pivots and positions the folded hardtop in the boot as needed to ensure maximum utilisation of the 220 litres of storage space available. When the top is up, the luggage compartment has a volume of 370 litres - 20 litres more than available in the BMW 3 Series Convertible.
