The KERS, or Kinetic Energy Recovery System, is a type of hybrid system that translates unused momentum into stored energy. But unlike typical regenerative braking systems or traditional hybrids, the KERS system uses that stored energy for an extra punch of power - at the press of a button.
KERS is highly complex and expensive to integrate, however, so this addition may or may not yet see production. Even the BMW F1 team is having some trouble with the technology, so adoption of this particular bleeding-edge item may have to wait a few more years.
Turbocharging, on the other hand, is a well-known tool, and BMW intends to use it to replace the current high-strung 5.0L, 507hp V10 with an even more powerful V8. The upcoming X5M and X6M will both get a 564hp version of the twin-turbo eight-pot, but the M5 is expected to get an even higher-spec variant rated at up to 600hp, reports AutoExpress.
Whatever BMW uses for its next-gen M5 drivetrain, however, expect it to be a tour de force of technology and capability, as the rumored M7 is not likely to make production, leaving the M5 as BMW's executive performance flagship. The next 5-series (preview pictured) is expected to make its debut at the Frankfurt Motor Show in September, but the M5 may wait until early 2010 for its debut.
