ActiveHybrid X6

The ActiveHybrid X6, due to go on sale in the U.S. later this year, represents one end of the spectrum: higher-power electric motors and a larger battery pack. As the first image shows, the new X6 model has a twin-turbo V8 gas engine with 400 horsepower. Though this is a reasonably efficient engine for its size, it certainly wasn't chosen primarily for its fuel economy.

• High efficient BMW V8 gasoline engine (300kW / 600Nm) with High Precision Injection and TwinPowerTurbo Max. Power (System) 375 KW/ 780 Nm.





• Two-Mode ActiveHybrid transmission (2 electric motors max. 67 KW/280Nm each, planetary gearbox, power split, 7 speeds).




• High Voltage Electronics (max. 425 Volts)




• High performance Ni-MH battery (312 volt / 2.4 KWh).

BMW's ActiveHybrid X6 uses a large NiMH battery pack and a new transmission with two integrated electric motors to augment its 400-horsepower gasoline engine.

• Electric motor A (67kW/260Nm)
  
• Electric motor B (63kW/ 280Nm)
• Electrical oil pump for transmission pressure during E Drive.
  
• Power split transmission with 3 planetary gear sets, 7 speeds.
  

The ActiveHybrid 7's electric motor is tucked away between the gas engine and a conventional 8-speed automatic transmission.
