Vehicle Overview - Hybrid: Introduction

The first stage of the BMW Group BMW EfficientDynamics was to develop a variety of measures to promote efficiency. These improvements were introduced through the entire model range via the normal series production vehicles.

BMW ActiveHybrid is an important component within the second stage and development strategy of BMW EfficientDynamics. It is based on the concept "Best of Hybrid". This enables the integration of each best component for different vehicle segments.

This poses two seemingly opposing development goals. On the one hand, a considerable increase in efficiency, so a consumption reduction up to 20 percent while still fulfilling the legal emissions standards and with a decreased CO2 emissions from BMW models with conventional propulsion. On the other hand, the BMW Group must offer the most dynamic hybrid vehicles in the competitive environment.

BMW launches its first series vehicle with hybrid technology to the market in December of 2009 as the BMW ActiveHybrid X6 (E72). Unlike all other hybrid vehicles currently on the market, this sets a record as the world's first sports activity Coupe with hybrid drive. This vehicle characterizes itself as having high efficiency, high power output and similar agility while reducing the average fuel consumption of the BMWX6 xDrive50i 20 percent.

The BMW EfficientDynamics results are achieved via the use of a full hybrid drive system which features a combination of V8 gasoline engine (N63) and electric propulsion. The BMW ActiveHybrid Technology enables driving via the following three means:

• purely electrical driving
• powerful internal combustion engine
• combination of both.

Purely electric mode allows CO2-free driving up to 40 mph. The internal combustion engine can then seemlessly start and take over the propulsion requirements.

This Drive system of the BMW ActiveHybrid X6 consists of a 400 hp strong V8 engine with BMW TwinPower Turbo technology and two electrical machines that are capable of creating 91 hp and 86 hp. The maximum possible combined system performance is 480 hp and the torque reaches a maximum of 575 lb-ft of torque.

The BMW ActiveHybrid X6 is characterized as the most powerful hybrid vehicle in the world. Its estimated acceleration time from 0 - 60 mph is under 5.4 seconds.
