BMW ActiveHybrid 7.

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 CO

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.
