The Geneva Motor Show 2010 is from 4th to 14th March 2010 and most of the Global majors are busy presenting their new concept cars ahead of the expo in order to make the mass aware of what the brand are going to showcase at the show.
Rumors were already in air about the car which fits in a segment in between 5-Series Sedan and 5-Series Touring.
BMW 5 Series Active Hybrid Engine
The hybrid 5-Series Concept will sport a TwinPower Turbo straight-6 cylinder gasoline mpfi engine, coupled with an 8-speed Automatic Transmission by BMW along with an electric drive.
BMW’s concept is unique from the current ActiveHybrids sold by Honda (CR-Z) and Toyota (Prius). But calling it unique means that it has a new drivetrain representing the next generation technology with BMW-exclusive intelligent interaction solution. The electric unit provided features high voltage batteries together producing 54 HP(40KW).
It features an Automatic Clutch which connects the electric motor to the combustion unit providing high torque which can be utilized when needed along with brake energy recovery system which saves fuel when brakes are applied. Climate control function featured on the BMW ActiveHybrid 7 along with the hybrid-based Auto Start Stop function contributes to the saved fuel as well.
The setup of the Automatic clutch is very much similar to what is seen in Porsche S Cayenne Hybrid which uses a SEPARATOR CLUTCH to engage and disengage the electric unit. While the brake energy recovery system is seen in many of the Hybrid cars.
Exclusive Features Of BMW Active Hybrid
Adaptation to current as well as future driving conditions is another feature exclusively provided by BMW where the car reads and interprets data indicating the changes figured in the driver’s wishes and exterior. Question remains how BMW interprets this data to which BMW gave an example by saying “Should the system determine, for example, that the autobahn ahead is about to lead downhill, the charge level of the high-voltage battery is intelligently controlled in advance to regain brake energy upfront with maximum efficiency.”
