Launched alongside the BMW 2 Series Coupe is the BMW 4 Series Convertible. The 3 Series Convertible replacement is offered here in a single 428i variant, in Luxury Line trim.

Measuring 4,638 mm long, 1,825 mm wide and 1,384 mm tall, with a 2,810 mm wheelbase, the BMW 4 Series Convertible is 26 mm longer, 43 mm wider and has a 50 mm longer wheelbase than its E93 predecessor. Front and rear tracks have also grown by 45 mm (to 1,545 mm) and 81 mm (to 1,594 mm) respectively.

The vehicle gets a three-piece folding hard top that opens in 20 seconds at speeds of up to 18 km/h. The roof’s headlining is claimed to cut noise by up to 2 dB over its predecessor. There are roll-over bars that, in critical situations, spring out from behind the rear seats in under 200 milliseconds.

With the roof up, the drag coefficient is 0.28 and there’s 370 litres of boot space (a 20-litre improvement). The numbers are 0.33 and 220 litres respectively in open-top mode. The folded roof is pivoted upwards in the boot by an electro-hydraulic loading assistance system to allow more storage space and easy access.

The windblock has been redesigned to be smaller, lighter, easier to use and more effective. When it’s not needed, it can now be stored behind the rear seat. There’s also a load-through feature that provides either a wide or small opening between the rear passenger compartment and boot.

Under that long bonnet lurks a 2.0 litre four-cylinder turbo petrol engine that develops 245 hp from 5,000-6,500 rpm and 350 Nm of torque from 1,250-4,800 rpm. With the help of an eight-speed sports auto with shift paddles, the vehicle does the century sprint in 6.4 seconds before hitting a 250 km/h top speed.

In Eco Pro mode, a sailing function decouples the engine and gearbox when you lift off the throttle between 50 and 160 km/h, to save fuel. Additionally, the Navigation System Professional’s Route-Ahead Assistant ‘sees’ upcoming road conditions and prompts drivers to reduce accelerator pressure in advance.

Fuel consumption is a claimed 6.6 litres per 100 km, but BMW claims that along with Eco Pro Route, which calculates the most economical route and displays both the fuel saved in percent and estimated travel time, drivers can save up to an extra five percent of fuel. Stop/start also comes as standard.

Our fully-imported (CBU) 428i Convertible comes with Adaptive M Sport suspension (only available on our 428i M Sport and 435i M Sport Coupes), 225/45 R18 multi-spoke alloys with run-flat tyres, xenon headlamps, fog lamps, front and rear parking sensors and chrome exterior trim. Unique to this Luxury Line car are extra chrome highlights on the front bumper, rear bumper and side gills, as opposed to the Sport Line- or M Sport-kitted Coupe variants.

Inside, you’ll find a touch-sensitive iDrive that controls an 8.8-inch Navigation System Professional, a folding rear bench, cruise control with braking function, auto headlamps and wipers, auto dual-zone air-con, a nine-speaker 205 W sound system, Fineline Anthracite interior trim with chrome accents, Dakota brown leather upholstery and a sports leather steering wheel.

Dual frontal and side airbags, DSC, ASC, CBC, DTC and roll-over protection are standard. Black Sapphire, Midnight Blue, Mineral White and Mineral Grey body colours are available. The price to pay is RM428,800, OTR without insurance. Included is a three-year/60,000 km BS+RI free service package.
