The car's wide center console rises up towards the instrument panel at the front, separating the driver and front passenger areas. This center space encompasses the audio control unit and its function buttons, the air conditioning control panel and air vents as well as the freestanding and frameless Control Display, all arranged above each other in a clear, horizontally partitioned structure.

The clear arrangement of the controls helps the driver to focus on what's happening ahead. Apart from the gear selector and the iDrive Controller, the center console also accommodates the Driving Experience Control switch and the engine start/stop button, all arranged within a newly designed function cluster with active haptic feedback. The control unit for the light functions is new and now consists of buttons positioned at the bottom of the instrument panel between the steering wheel and the driver's door. A leather M Sport steering wheel with multifunction buttons and shift paddles for manual gear selection is standard.

The newly developed sports seats offer high levels of long-distance comfort and excellent lateral support. The headrests are integrated into the backrests and can be adjusted for both height and fore/aft position. A semi-electric folding function has been included for the front seat backrests, which is activated by using a high-quality leather strap located on each seatback to facilitate convenient entry and exit for the rear passengers.

The sports seats are upholstered in standard premium Merino Individual leather with extended leather appointments. Decorative stitching in a contrasting color accentuates both the sporting contours and the rear seats' styling as individual seats.

There are large door pockets, a roomy glove compartment, two cup-holders under the center console's trim finisher and a large storage compartment under the armrest's longitudinally divided covers for stowing travel accessories, beverages and other items.

The rear backrest in the first-ever BMW 8 Series Convertible has a 50:50 split design. The backrest sections can be folded down either individually or together to further increase cargo capacity. The folding mechanism is released by means of levers inside the cargo compartment. Automatic trunk lid operation is a standard feature on the first-ever BMW 8 Series Convertible, while the Comfort Access option permits hands-free opening and closing of the trunk lid.

The standard specification for the new BMW M850i xDrive Convertible contains exclusive design features and options to enhance the driving experience. In addition to multifunction seats and the M leather steering wheel, there are M pedals, M driver's footrest and special floor mats to imbue the cabin with a distinctly sporty flair. The illuminated door sills and the display in the instrument cluster bear the BMW M Performance Automobile model badge or the M logo respectively.

The luxurious side of the first-ever BMW 8 Series Convertible's character is shown with the help of a wide array of distinctive optional extras. Newly designed climate seats for driver and front passenger are available as an upgrade to the standard heated seats. For the first time, the cooled air is drawn in from the interior then guided along the body to the seats' built-in fans for particularly effective temperature control of the seat cushions and backrests.

The standard ambient light feature emphasizes the forward-pointing lines inside the car to striking effect. Indirect illumination of the contour lines running along the center console and the door shoulders using precisely positioned LED optical fibers creates an exclusive mood. The color of the light can be changed via the iDrive menu. In addition to this, the Dynamic interior light function emits pulsating light signals in specific situations. These signals appear on the inner panelling of an open door when the engine is running and on the instrument panel in response to an incoming phone call.

The standard Harman Kardon audio system comprises twelve speakers and a digital amplifier, while the pinnacle of the audio line-up is without doubt the optional Bowers & Wilkins Diamond Surround Sound System. The unrivalled Diamond loudspeaker technology, fully active 12-channel amplifier with an output of 1,375 watts, dynamic equalizing and 12 partly illuminated speakers combine together to deliver a beautifully precise and multifaceted acoustic experience whose pristine quality can be enjoyed in equal measure from all seats in the new BMW 8 Series Convertible.

The optional glass applications for selected controls add both visual and tactile highlights to the interior design. This exclusive design feature adorns the gear selector, the iDrive Controller, the start/stop button and the volume control for the audio system. An illuminated '8' can be seen through the glass surface of the gear selector.

Remote Start is available as part of the optional Comfort Seating Package, which also includes front ventilated seats and heated front seat armrests and steering wheel.

The BMW M Performance model that will be available from launch provides a particularly impressive demonstration of the first-ever BMW 8 Series Convertible's sporting essence. Under the hood lies a 523 hp BMW TwinPower Turbo V8 engine that has undergone extensive upgrades and refinement. It serves up an intense form of the unmistakable power delivery and acoustics of eight-cylinder units and is every bit as captivating and emotionally thrilling as the car it powers.

Power is transferred to the wheels via the latest-generation eight-speed Steptronic Sport transmission that boasts a wider gear ratio spread, even sportier gear shifts and can be operated by means of shift paddles on the steering wheel. Completing the all-round package for an engaging driving experience is the BMW xDrive intelligent all-wheel-drive system, which is fitted in a newly improved version that has been tuned for this specific model. The rear-wheel bias of the xDrive system and the rear differential lock fitted as standard on the first-ever BMW M850i xDrive Convertible ensure maximum agility and precision when the car's sporting capabilities are being put to the test.

The launch of the first-ever BMW M850i xDrive Convertible also marks the premiere of a new BMW TwinPower Turbo V8 engine. The latest generation of the 4.4-liter eight-cylinder engine has been radically revised with numerous detailed improvements. Two twin-scroll turbochargers with charge air cooling located within the V-shaped space between the cylinder banks, High Precision Injection, VALVETRONIC fully variable valve control and Double-VANOS variable camshaft timing all form part of the M Performance TwinPower Turbo technology, whose extensive overhaul has given a substantial boost to maximum power, torque and efficiency.

The new V8 engine serves up an enthralling soundtrack, which is enhanced by the standard flap-controlled sports exhaust system. It boasts a wonderfully versatile character that can also adapt itself to effortlessly relaxed cruising. The Driving Experience Control switch can be used to activate both extremely sporty and distinctly comfort-oriented powertrain settings. In the Sport and Sport+ modes, accelerator response as well as the V8 engine's power delivery and acoustics - which take on a particularly distinctive note in the Sport+ setting - are all configured for an exhilarating driving experience.

A new aluminium alloy has been used to increase the strength of the engine block. The wire-arc sprayed iron coating for the cylinder walls serves to reduce frictional losses. Reinforced, Grafal-coated pistons and optimized piston rings are designed to endure the stress on the crank drive that comes with the extra output and torque. To enhance engine smoothness, torsional vibration is minimized with the help of a viscous damper on the crankshaft.

To achieve rapid combustion, the intake ports have been optimized for higher flow. The enlarged twin-scroll turbochargers and the variable valve and camshaft timing enable throttle losses during the gas-exchange cycle to be eliminated as far as possible and allow effective use of exhaust gas recirculation for lowering fuel consumption.

Electrically-controlled wastegate actuators are used to ensure an extremely quick build-up of boost pressure, while electric blow-off valves are integrated into the compressor housing to enhance the turbocharger sound during boost pressure release while at the same time as keeping emissions as low as possible in all operating conditions. The air intake manifold has been redesigned and a connection between the air ducts for both cylinder banks ensures even pulsation during gas exchange, resulting in higher torque at lower engine speeds.

The multi-hole fuel injectors are positioned centrally between the valves and spray fuel at a maximum pressure that has been increased from 2,900 psi to 5,076 psi. This optimizes both the metering of the fuel and the engine's emissions performance. The BMW TwinPower Turbo V8 engine also takes advantage of a new ignition system and engine management.

Thermal shielding and the cooling circulation system have both undergone extensive modification. An upstream coolant radiator helps meet the high demands on the engine's temperature management during extremely spirited driving.

The new BMW TwinPower Turbo V8 engine now generates 523 hp between 5,500 and 6,000 rpm and 553 lb-ft of torque from 1,800 to 4,600 rpm.

The latest improved version of the Sport automatic transmission features a weight-reducing design, a newly developed controller and a wider gear ratio spread. As a result, it is possible to achieve efficiency gains with reduced engine speeds, particularly when driving in higher gears. At the same time, the eight-speed Steptronic Sport transmission now shifts gear more sharply courtesy of optimized hydraulics control. A new generation of torsion dampers that reduce rotational forces within the powertrain help improve both driving comfort and shift smoothness. Integral twin-damper systems for isolating vibrations reduce the degree of slip at the torque converter lock-up clutch.

Shift paddles on the steering wheel are included as standard for manual gear selection, while a Launch Control function allows for accelerating from a standing start with maximum available traction.
