Both hybrids are luxury cars and will hit the U.S. this year

BMW has announced a pair of new hybrid vehicles that will be making their official debut at the Frankfurt Motor Show in September. The vehicles will hit American shores in Q4 2009 and the first one is called the BMW ActiveHybrid X6.

The ActiveHybrid X6 uses a hybrid drivetrain consisting of a 400hp twin-turbocharged V8 engine and two electric synchronous motors developing 91hp and 86hp respectively. The maximum power output of the entire power train is 480hp and 575 lb-ft of torque. The hybrid power train can push the SUV from a standstill to 60 mph in 5.4 seconds while improving fuel economy by 20% compared to the standard X6. The hybrid power train produces 231 grams of CO2 per kilometer.

At speeds of up to 37 mph, the vehicle will run exclusively on battery power and the combustion engine will be activated only when needed. The transmission used in the hybrid is a 7-speed automatic that can be operated manually. Power for the electric motors in the X6 comes from NiMH battery packs placed under the floor of the luggage compartment and the vehicle has the same cargo capacity as the standard X6. The maximum driving range on electric power alone is a mere 1.6 miles.

BMW also announced its new ActiveHybrid 7 based on the BMW 750i. The vehicle shares a power train similar to what the X6 uses with a twin-turbo V8 and 3-phase synchronous electric motors. The total power output for the vehicle is 455 hp with 516 lb-ft of torque. The car uses an 8-speed automatic transmission and power for the electric motors comes from a lithium-ion battery.

BMW claims that the hybrid power system allows the ActiveHybrid 7 to get 15% better fuel economy than the 750i or 750il. The car has automatic start and stop of the combustion engine and the AC system will continue to work when the vehicle isn’t running. The car has two onboard power networks with a 12-volt network operating the AC and some other systems and a 120-volt system powering the electric motors.

The lithium-ion battery is placed inside the floor of the luggage compartment, has 400 watt-hours of power, and uses 35 cells and an integrated control unit. The battery measures 14.6 x 8.7 x 9.1-inches and weighs 59.5 pounds. BMW says that the ActiveHybrid 7 can go from 0 to 60 mph in 4.8 seconds.

BMW says that the luxury hybrid market is one of the fastest growing in the auto sector. Toyota owns the low-end hybrid market with its new 2010 Prius.
