Days before the unveiling at the Geneva Motor Show, BMW made a grand presentation of the 5-Series ActiveHybrid Concept. Since last August, rumors had been heard about this car, which slots in between the previously released 5-Series Sedan and the still-to-come 5-Series Touring.
Featured on the hybrid 5-Series Concept is a TwinPower Turbo straight-six gasoline engine, combined with an eight-speed automatic transmission and an electric drive. BMW's concept is unlike the current ActiveHybrids that have been presented in the past.
It has a new drivetrain that appears to be a preview of the next-generation technology, with its BMW-exclusive intelligent interaction solution. The electric motor is powered by a high-voltage battery pack and produces up to 40 kW (54 hp).
An automatic clutch connects the electric motor to the gasoline engine, resulting to a high torque that becomes available when required. The hybrid system also serves as an energy recovery system when the brakes are being applied. More fuel is saved due to the hybrid-based Auto Start Stop function and the same climate control function featured on the BMW ActiveHybrid 7.
Another exclusive feature of this concept is its ability to adapt to current as well as future driving conditions. The car prepares for a change in requirements when it reads data that could indicate changes in the exterior and in the driver's own "wishes". The system interprets the data, which refer to engine and chassis management as well as those saved in the navigation system on the route chosen by the drive.
Since these are abstract elements, it's mindboggling how BMW intends to interpret the data, especially those that pertain to the driver's "wishes".
BMW took the market by storm with the Concept 5 Series ActiveHybrid. Boasting of next-generation electronics to manage the vehicle’s functions, customers can enjoy a new brand of “Sheer Driving Pleasure” that has been the hallmark of BMW for decades.
With optimal energy, fuel and power efficiency, this series is a powerhouse. Drivers can easily personalize the manner in which the two powertrains in the BMW Concept 5 Series ActiveHybrid operate to deliver the performance required.
The system is even smart enough to recognize certain driving conditions to further personalize the two engines’ performance as well. All of these are done while managing the ancillary units and functions in the car’s interiors, with an eye for maximum efficiency.
You’ll be amazed at how much information and parameters the BMW Concept 5 Series ActiveHybrid can take in just to manage the car’s performance and functions. The system’s power electronics can smartly manage the vehicle’s energy requirements in order to maximize the energy produced and used in response to whatever driving conditions are encountered.
In fact, adapting power management in response to driving conditions is the highlight of the BMW Concept 5 Series ActiveHybrid’s capabilities. Because driving conditions will mean a change in power and performance requirements, the electronic components inside the Concept 5 Series ActiveHybrid analyze outside conditions and compare it with current driver preferences to come up with a change forecast.
With this forecast, the system can then prepare the powerhouses beneath the car’s hood to respond accurately and speedily to changing requirements. The system uses various sensors to analyze environmental conditions outside the vehicle, including the built-in driver assistance sensors.
The system also saves data derived from the navigation system, which records the driver’s daily driving habits and routes, and adds the information to the equation when calculating possible changes in driving conditions. With the information gathered, the system is able to prepare well in advance and come up with ways to efficiently manage and distribute available energy.
