At first blush, the idea of running a hybrid on a chassis dyno is silly. A dyno is all about power and performance, and a hybrid, well, isn't.
That is, unless the hybrid is the 2010 BMW ActiveHybrid X6, of which its creators reckon is the most powerful in the world. Have a look at its stats as claimed by BMW -- 480 horsepower and a staggering 575 lb-ft of torque.
This prodigious output comes by way of a 4.4-liter twin-turbo V8 and a two-mode hybrid system. The product of the now-defunct collaboration between GM, DaimlerChrysler and BMW, this hybrid system is fundamentally similar to that of the Chevy Silverado Hybrid and Tahoe Hybrid. Pairing these two power generators together is like dashing creatine powder onto a medium-rare strip steak.
This ActiveHybrid X6, then, is a hybrid with a chip on its shoulder, just begging to have its claims put to the test. And test it we did, strapping it down to a chassis dyno and making it sing. Er, whir and hum quietly.
