PRESS RELEASE + Expand

BMW is proud to present the most supreme and luxurious rendition of
hybrid technology ever seen so far in the automobile: BMW ActiveHybrid 7.

Based on the BMW 7 Series, this unique car sets new standards for effi ciency
in the luxury class. BMW ActiveHybrid 7 is the fi rst car in the world to combine
a V8 gasoline engine, eight-speed automatic transmission and an electric motor
as a mild hybrid concept.

This symbiosis of an upgraded eight-cylinder with BMW TwinPower Turbo
Technology and High Precision Injection with a three-phase synchronous electric
motor gives BMW ActiveHybrid 7 overall system output of 342 kW/465 hp
and maximum torque of 700 Newton-metres/516 lb-ft. Power is transmitted
via an eight-speed automatic transmission, with the electric motor positioned
in compact confi guration between the combustion engine and the converter
on the automatic transmission receiving its supply of energy from a lithium-ion
battery developed especially for use in the automobile.

Precisely controlled interaction of both power sources serves to optimise not
only the effi ciency but also the dynamic performance and superior comfort of
BMW ActiveHybrid 7. The result is a truly thrilling driving experience and, at the
same time, a unique demonstration of hybrid technology with its outstanding
potential. BMW ActiveHybrid 7accelerates to 100 km/h in a mere 4.9 seconds,
while keeping average fuel consumption in the EU test cycle to 9.4 litres/
100 kilometres (equivalent to 29.1 mpg imp) and restricting CO2 emissions to
just 219 grams per kilometre.

Hybrid technology also provides new options for the particularly effi cient
use and enjoyment of additional comfort functions. As an example,
BMW ActiveHybrid 7 is the fi rst BMW with automatic transmission to feature
an Auto Start Stop function avoiding idle speed operation of the engine
when at a standstill or in traffi c jams. A further signifi cant advantage is that
the air conditioning and ventilation system remains fully operational also with
the engine switched off, power being supplied directly through the 120-volt
on-board network operating on the lithium-ion battery.

This unique concept of engine management for the first allows truly effective
climate control also at a standstill in a luxury performance car, cooling the interior
of BMW ActiveHybrid 7 to a signifi cantly lower temperature right from the start,
before the driver even fi res the engine.

Special displays in the instrument cluster and the Control Display inform the
occupants of the degree of effi ciency and the current operating status of the
hybrid components. Nineteen-inch light-alloy rims in aerodynamically optimised
ten-spoke turbine wheel design created exclusively for BMW ActiveHybrid 7 as
well as model designations on the luggage compartment lid, the C-pillars
behind the side windows and on the door cutouts clearly set aside the hybrid
models from their “regular” counterparts right from the start. And last but
certainly not least, BMW ActiveHybrid 7 is also available in Bluewater metallic
exterior paintwork exclusive to this very special model.

Like the existing models within the BMW 7 Series, BMW’s fi rst luxury saloon
with hybrid drive is entering the market in two body variants. The extended
version of BMW ActiveHybrid 7 comes with wheelbase increased by 14 centimetres
or 5.5", benefi ting exclusively the rear-seat passengers. And to optimise
the driving experience and grand touring comfort for individual requirements,
both models are available with a wide range of options from the portfolio of
equipment and accessories offered on the BMW 7 Series.

2013 BMW Alpina B7 Review [Car and Driver]

[MCMLXXXIX]

fantastic!
this thing has a lot of power!

[the infamous...]

[YYdoodle]

Man BMW isn't playing around when it comes to getting power from its hybrid technology!

Is this color reserved solely for hybrid cars or will it be available for regular F01 too?

[xDrive50i]

I wonder if BMW will offer an Active Hybrid 7 xDrive version too, that would be cool.

[zibawal]

When does it come out and if there will be eco credit?

[Bimmerboy888]

Thanks for the wallpapers! I wish my car had a climate control like that one! Haha. Great stuff!

Very promising, can't wait to see the curb weight and the distribution to determine if the car is up to snuff of BMW heritage. I am surprised they didn't include LCD instrument panel in this technowizardry car.

What are you talking about? The instrument cluster's lower portion IS a high resolution LCD panel!!!

I'm currious about this photo and maybe someone could shead some light on it.

What I'm wondering about the electric motor (No. 1 in photo) between the engine and the torque converter. Does that thing generate electricity for the batteries and then turn around and convert to power the transmission in hybrid mode?

I was thinking about the process - is this correct:

• When you start off the gas engine powers the car and charges the system via No. 1.
  
• Once the car is rolling and the batteries are charged, then No. 1 become a electric motor to power the transmission using battery power?

Those electrodes (red box on 1st photo) coming off the motor as massive. I figure they must be transferring and/or receiving huge amounts of power at low voltage. In the 2nd photo, notice how big the orange cables are going back to the batteries.

If there is enough power in the batteries, the car should be able to start moving with the electric motor and also kick start the V8. Both the V8 and the electric motor are used during acceleration and when the car is coasting or your braking, the electric motor is used as a generator and charges the battery to replenish the energy used during acceleration. The ActiveHybrid7 does NOT have an electric mode only like most other hybrid cars. This means that the car can not be driven on electricity only. The ActiveHybrid7 uses the electric motor during acceleration to enhance the performance of the car as well as the efficiency since the car will require the most amount of gas during acceleration.

I would assume that the (Lithium Ion) battery pack has a string voltage of 480Vdc or something thereabouts.
