2010 BMW ActiveHybrid X6 Test Drive 4.4 L TwinPower Turbo V8

In late 2009, BMW introduced an X6 featuring a version of the Global Hybrid Cooperation hybrid power train, popularly known as the two-mode hybrid system. This car was confirmed as being called the BMW ActiveHybrid X6, and it is the world#8217;s most powerful hybrid vehicle, it will not be sold in the UK. The production vehicle was unveiled alongside a 7-series hybrid at the 2009 Frankfurt Auto Show.

The ActiveHybrid X6 went on sale in December 2009 in the US market with a base price of US$89,765.

The drive system featured in the BMW ActiveHybrid X6 consists of a 300 kW (407 hp) V8 power unit with BMW TwinPower Turbo Technology and two electric engines developing 67 kW (91 hp) and, respectively, 63 kW (86 hp.) Maximum system output is 357 kW (485 hp), peak torque is 780 Newton-meters (575 lb-ft.)

BMW ActiveHybrid technology offers the driver three significant options: to drive under electric power alone, to use the power of the combustion engine, or to benefit from the combination of both drive modes for short periods of maximum acceleration, using the 485 maximum. Driving completely free of CO2 in the electric mode is possible up to a speed of 37 mph (60 km/h). The hybrid also employs stop-start technology and other energy saving measures to help improve efficiency.

The core-vehicle is however very heavy and the petrol power unit limits the extent to which fuel consumption can be reduced in absolute terms. The Turbo-Diesel models in the X6 range use less fuel, for example.

Let#8217;s start by congratulating BMW for bringing its first batch of hybrids to market (the 7 Series ActiveHybrid is launching alongside the X6). In everyday traffic, the hybrid system helps keep fuel consumption down – to a still-lame 18 mpg combined (estimated) – and, since the engine can shut down at stops, the ultra-quiet interior made sitting in Miami traffic during our preview drive almost a pleasure.

Nevertheless, there#8217;s still a lot of vehicle here that hampers any attempt at real fuel efficiency gains. The X6 ActiveHybrid weighs 5,688 pounds for crying out loud – 400 pounds more than the non-hybrid. This vehicle simply doesn#8217;t makes a lot of sense for anyone actually interested in fuel efficiency.

Who does it make sense for? Follow us past the break as we try to find out.

The ActiveHybrid powertrain in the X6 is a complex animal, being that it#8217;s made up of a twin-turbo 4.4-liter V8 engine, two electric motors (one that puts out 91 hp and a smaller brother that manages 86 hp), three planetary gearsets and a 2.4 kWh NiMH battery pack. All that machinery manages to produce 357 kW (485 horsepower) and 780 Nm (575 pound-feet) of torque.

This is what BMW has created out of the two-mode hybrid system that the Bavarians co-developed with General Motors and Mercedes (think Chevrolet Tahoe Hybrid and Mercedes-Benz ML450 Hybrid). BMW claims its hybrid SUV can achieve fuel efficiency of up to 9.9 l/100 km (about 24 mpg U.S.) on the European drive cycle, but during our a few hours in the 2010 BMW X6 ActiveHybrid Sports Activity Coupe, we averaged just 14.8 liters (16 mpg U.S.).

Oh, the engine. That#8217;s right, there is a gasoline engine in there too, and it is a good one, though that is easy to overlook when there is some rather impressive electric-drive technology on hand. The 400-hp twin-turbo direct-injection V8 that debuted in the X6 xDrive50i nestles its two turbines in the valley of the engine#8217;s vee for a shorter path to the turbos and improved throttle response.

In this hybrid configuration the engine is stripped of all its conventional accessories, with all ancillary systems converted to electric power rather than using drive belts that depend on the engine spinning.

In the end, we#8217;re not sure who will want the X6 ActiveHybrid. Most likely they#8217;ll be people who own an aging BMW X5 and want something new with more power and no penalty at the pump (at least compared to the rest of the X6 lineup). If past popularity of big BMWs is any indication, there is certainly a market for the X6 ActiveHybrid. Today, about 20 percent of BMW sales are X models.

Introduced in 1999, the X5 was the brand#8217;s first SUV and remains the most popular, with 911,000 sales. The X3 has sold 554,000 and the X6, introduced just last year, has already sold 57,000 units.
