BMW 8 Series Convertible Now Official, Starts at $121,400
The suspension system for the BMW 8 Series Convertible has been tuned down to the finest detail to the powertrain technology. Moreover, all the vehicle dynamics-related systems have been linked up with one another via the high-speed data transfer system called FlexRay to create an overall package geared towards maximum performance.
Constant measurement of the driving situation data by sensors forms the basis for coordinated system responses. Within a split second, the control unit integrated into the braking system and DSC is able to adapt the powertrain and suspension functions to changing situations, such as varying road surface conditions, sudden braking, spontaneous steering maneuvers and extreme acceleration. Here, the steering, four-wheel-drive system, electronically controlled differential lock and active roll stabilization are all employed to assist the stabilizing effect of brake intervention on individual wheels and adjustment of drive torque. A hierarchical control structure guarantees optimal control of the relevant actuators.
For example, to optimize directional stability when braking heavily on road surfaces with varying grip levels under the right and left-hand wheels, a steering impulse can be transmitted to inform the driver of the necessity to adjust their line. With carefully judged steering inputs on the rear axle, it is possible to counteract a tendency to oversteer or understeer. Adjustments by the active roll stabilization system will assist in enhancing stability and agility. Precisely controlled anti-roll bar swivel motors can optimize traction in fast bends. Centrally evaluated data on the driving situation optimizes the efficiency of the BMW xDrive system’s responses.
Optimized Weight
BMW EfficientLightweight includes the use of an intelligent material mix to optimize both weight and body/suspension rigidity. In addition to the supporting structures at the front and rear of the car, other components such as the doors, hood and the front firewall of the first-ever BMW 8 Series Convertible are made of aluminum. The bracing tube for the passenger compartment is made from magnesium and the center tunnel is made of CFRP. The front axle is made almost completely from aluminum. The rear axle features a combination of lightweight steel construction with wheel carriers and forged control arms in aluminum.
A particularly wide variety of standard and optionally available driver assistance systems marks the BMW 8 Series Convertible as an extremely advanced model within its segment. The systems really come into their own when driving longer distances by relieving the strain on the driver in monotonous situations, such as traffic jams or slow-moving traffic.
They enhance comfort and safety both in urban traffic and on longer trips by providing targeted assistance in complex traffic situations. The driver assistance systems process camera images as well as the data gathered by ultrasonic and radar sensors to monitor the vehicle’s surroundings, to warn of potential hazards and to minimise the risk of an accident with corrective braking or steering inputs. These integral features of the BMW Personal Co-Pilot represent the latest advances on the road to automated driving.
The BMW 8 Series Convertible is equipped with standard Collision and Pedestrian Warning with City Braking function, the latest version of which alerts the driver when a cyclist is detected. Depending on the situation, the system can bring the vehicle to a halt to either avoid a collision or minimize its consequences.
The optional Driving Assistant Professional offers comprehensive assistance for comfortable and safe driving. This package includes Active Cruise Control with Stop & Go function. It can be used at speeds up to 130 mph and maintains the desired speed while taking not only the traffic situation into account, but also the selected distance to vehicles in front. If required, the system is able to brake the car to a stop then pull away again automatically after being stationary for up to 30 seconds, meaning greater comfort in stop-start traffic. Camera images and data from a front radar system are used for distance control.
In addition to Active Cruise Control with Stop & Go function, this complete package also includes the Steering and Lane Control assistant. To allow convenient activation of the two systems, the BMW 8 Series Convertible is fitted with a special button on the standard multifunction steering wheel for switching on the Active Cruise Control and Steering and lane control assistant simultaneously. A mode button can be pressed to switch to using Active Cruise Control on its own.
Another component of the Driving Assistant Professional is the Lane Keeping Assistant with Active Side Collision Protection. This is made up of the Lane Departure Warning and Active Blind Spot Detection systems, which are active from 44 to 130 mph and 12 mph up to top speed respectively and help the driver guide the vehicle back onto the correct path with an active turn of the steering.
Besides emitting visual warning signals and causing the steering wheel to vibrate, active side collision protection also uses active steering intervention to help avoid a collision. The Driving Assistant Professional also includes the evasion aid, which now also reacts to pedestrians. The Crossing Traffic Warning, which reduces the danger of a collision when maneuvering forwards towards roads that are obstructed from the driver’s view, now also includes brake intervention.
Easier parking with Backup Assistant
Drivers of the first-ever BMW 8 Series Convertible receive effective assistance when parking and maneuvering. The standard Park Distance Control (PDC) with sensors at the front and rear is standard and provides visual and acoustic warnings to avoid colliding with obstacles at the sides or rear of the vehicle. The standard Parking Assistant is able to automatically select suitable parallel parking spaces and maneuver into them. The spaces are identified by ultrasonic sensors as the vehicle drives past. Once it has been activated by simply pressing and holding a button on the center console, the system takes care of controlling the accelerator, brakes and steering as well as changing gear.
The Parking Assistant’s range of functions also includes the Backup Assistant, which helps the driver when exiting parking spaces and maneuvering within a confined space. The system assumes the task of steering when backing up by tracing the vehicle’s last forward movements in reverse. All the driver has to do is operate the accelerator and brake pedals and monitor the vehicle’s surroundings. A distance of up to 55 yards can be covered in this way at speeds of up to 6 mph. The system is deactivated if either of these values is exceeded.
The included standard camera system is designed to afford drivers a clear all-round view through Rear, Top View, Panorama View and 3D View functions. A 360-degree image of the vehicle and its surroundings is shown on the Control Display from different perspectives. The Remote 3D View function additionally gives drivers the ability to call up a three-dimensional live image of their vehicle and its immediate vicinity on their smartphone.
The BMW 8 Series Convertible comes standard with the BMW Live Cockpit Professional, which combines a new display and control concept and maximum connectivity into a superb all-round package. The latest-generation display and control concept consists of a high-resolution instrument cluster behind the steering wheel with a screen diagonal of 12.3 inches and a 10.25?inch Control Display.
BMW Connected
BMW Connected is the companion app for BMW drivers. Intelligent connectivity helps users to reach their destination easily and with minimal stress – and not only from within their car; BMW Connected is an all-embracing concept designed to seamlessly connect the driver and their smartphone with their vehicle.
At the heart of it all is the Open Mobility Cloud, which allows the app to connect the car with the customer’s digital devices. These could include the iPhone and Apple Watch, smartphones and smartwatches running the Android operating system, Alexa-compatible smart devices and Google Home. For instance, the BMW Connected app can import appointments and addresses from the customer’s calendar entries straight into the navigation system to begin route guidance. The system calculates the optimum departure time based on real-time traffic information and notifies the driver with a message on their smartphone when it is time to leave. As the vehicle is linked up via the Open Mobility Cloud, it is able to access the calculated route directly when the navigation system starts up.
Remote Software Upgrade Capable
The BMW 8 Series Convertible is Remote Software Upgrade capable. This feature keeps the vehicle up to date with the latest software. All updates can be loaded over the air, similar to smartphones. The upgrades can be loaded onto a smartphone via the BMW Connected app when connected to a Wi-Fi network or imported directly via the BMW’s built-in SIM card. The timing and availability of updates will be determined at a future date.
