2019 BMW 8-Series Convertible

BMW is forging ahead with its model offensive in the luxury segment with the presentation of an open-top sports car which explores the highest reaches of dynamic flair, emotionality and exclusivity. The new BMW 8-Series Convertible blends ultra-sporty driving properties with distinctive design elegance and an extremely exclusive taste of driving pleasure in an open-top four-seater. The newly developed soft-top roof enhances the two-door car's low, sporting lines when closed - and its sweeping elegance once open. The powertrain and chassis technology developed for the BMW 8-Series was tuned on the race track as well as the road. It serves up impressive performance attributes and peerless levels of poise and assurance, all of which are experienced with even greater intensity when the sun and wind are invited in. Model-specific equipment features designed to enhance comfort and state-of-the-art innovations when it comes to control & operation, driver assistance and connectivity serve up an open-top experience as modern as it is luxurious.

The growth of the BMW 8-Series range to include an open-top sports car for the luxury segment once again augments the brand's presence in this vehicle class. The expansion of its luxury car portfolio is one of the future-focused areas the BMW Group has identified - as part of its NUMBER ONE > NEXT strategy - to secure the company's long-term growth. The distinctive character profile of the new BMW 8-Series Convertible allows it to put down a particularly attractive marker in this market segment and win over new target groups in the process. The open-top model will be produced alongside the BMW 8-Series Coupe at BMW Plant Dingolfing. The Bavarian facility is the traditional birthplace of the BMW 7-Series Sedan and boasts outstanding expertise in the manufacture of luxury cars. The worldwide market launch of the new BMW 8-Series Convertible will begin in March 2019.

Engines, transmission and BMW xDrive

Two attractive power units will be available for the new BMW 8-Series Convertible from launch, both of which impress in their own individual ways on a platform of supreme power delivery - and, in so doing, reveal the full breadth of the open-top four-seater's character. The new BMW M850i Convertible wears the tag of high-calibre sports car with particular ease. It is powered by a latest-generation V8 engine developing 390 kW/530 hp. The unit's unmistakable eight-cylinder character is highlighted both in the imposing fashion in which it serves up its power and the emotionally lavish engine note that provides the soundtrack. Cue a driving experience of rare allure and awe - especially with the roof down. Torque on tap from low in the engine speed range combined with eye-catching efficiency and an appetite for covering long distances mark out the six-cylinder in-line diesel engine at the heart of the new BMW 840d xDrive Convertible. With maximum output of 235 kW/320 hp and a degree of smoothness head and shoulders beyond what you would expect from a diesel engine, it follows the family lead in offering driving pleasure of satisfying variety; pleasurable cruising, dynamic sprints and a relaxed touring ambience are all on the menu.

Power transfer in the two models is via the latest version of the eight-speed Steptronic Sport transmission, which allows the driver to change gears manually using shift buttons on the steering wheel as standard. The engine's power is fed through to the road surface by the latest generation of the BMW xDrive system. The rear-wheel-biased set-up of the intelligent all-wheel-drive system provides exceptional agility and precision in dynamic driving situations, as does the M Sport differential with active locking function at the rear axle fitted as standard on the BMW M850i xDrive Convertible.

V8 engine: imposing power, characterful soundtrack

A 4.4-litre eight-cylinder engine from the latest crop infuses the new BMW M850i xDrive Convertible with imposing power delivery, backed by a soundtrack that can usefully be described as rich in character. The new V8 seizes the attention with a 50 kW/68 hp hike in output over its predecessor (to 390 kW/530 hp) achieved without any increase in weight, plus a 100 Nm (74 lb-ft) boost in peak torque to 750 Nm (553 lb-ft).

The attendant M Performance TwinPower Turbo technology includes two twin-scroll turbochargers with charge air cooling nestling in the V between the cylinder banks, High Precision Injection, VALVETRONIC fully variable valve control and Double-VANOS variable camshaft timing.

The far-reaching new measures help to produce instantaneous power delivery and sustained thrust - accompanied by a marvellously captivating soundtrack, even greater impact by the standard flap-controlled M sports exhaust system. The new V8 serves up peak torque between 1,800 and 4,600 rpm and generates maximum output between 5,500 and 6,000 rpm. The BMW M850i xDrive Convertible sprints from 0 to 100 km/h (62 mph) in just 3.9 seconds. Combined fuel consumption comes in at 10.0 - 9.9 litres per 100 kilometres (28.3 - 28.5 mpg imp), with combined CO2 emissions stated as 229 - 225 grams per kilometre. Larger catalytic converters mounted close to the engine and a gasoline particulate filter minimise the emissions of the new V8 engine, which meets all the relevant exhaust emission standards worldwide, including the Euro 6d-TEMP norm.

Six-cylinder in-line diesel engine brimming with power and efficiency

The new BMW 840d xDrive Convertible benefits from a type of engine no other car in its segment can offer - a 3.0-litre straight-six diesel. The unit's BMW TwinPower Turbo technology comprises multi-stage turbocharging and common-rail direction injection with piezo injector. These generate maximum pressure of 2,500 bar to supply fuel to the engine in extremely precise quantities and ensure clean combustion. With maximum output of 235 kW/320 hp at 4,400 rpm and peak torque of 680 Nm (501 lb-ft) on tap between 1,750 and 2,250 rpm, the six-cylinder in-line diesel develops majestic pulling power.

With its inimitable performance characteristics, this power unit encourages relaxed cruising at low engine speeds and powerful mid-range sprints in equal measure. Pressing the accelerator hard enables a 0 to 100 km/h (62 mph) dash in 5.2 seconds - as the model-specific sports exhaust system runs through its full-blooded acoustic repertoire. The engine also represents a compelling proposition over long distances, displaying tremendous refinement and exemplary efficiency - the latter reflected in average fuel consumption of 6.3 - 5.9 litres per 100 kilometres (44.8 - 47.9 mpg imp) and CO2 emissions of 165 - 155 grams per kilometre. Thanks to exhaust gas treatment using BMW BluePerformance technology (including an SCR catalyst with AdBlue injection), the new BMW 840d xDrive Convertible fulfils the stipulations of the Euro 6d-TEMP standard.

Eight-speed Steptronic transmission with gearshift paddles on the steering wheel

Both engines deliver their power through the latest version of the eight-speed Steptronic Sport transmission. When driving in higher gears, in particular, the transmission uses its wider gear spacing to keep engine speeds low and, in so doing, reduce fuel consumption. Added to which, the latest generation of the eight-speed Steptronic Sport has reduced torque converter slip and further developed torsion dampers that reduce rotational irregularities within the powertrain and therefore help to optimise both driving comfort and shift smoothness.

The transmission's optimised hydraulic control plays a key role in sharpening the shift dynamics. Manual gear changes can be carried out using the standard shift paddles on the steering wheel. The Launch Control function allows the car to power off the line with optimal traction and unbeatable dynamic flair.
