| 2011 BMW 760li |
It has been barely a year since BMW's "2011 BMW 760li " was introduced, but what an eventful year for BMW. No mere evolutionary product, The 2011 BMW 760li was instead a bold statement about who BMW is, what BMW stands for, and where BMW intends to go. Let's take a look now at the most significant new technology in this new engine: direct fuel injection. Indeed, this is the first direct-injected gasoline . V-12 engine ever offered in a production automobile, and the first direct-injected gasoline engine to meet contemporary expectations regarding emission control .Direct fuel injection means injection of the fuel directly into the combustion chamber, rather into the intake port as is the norm; it has been chosen and developed by BMW's power train engineers to boost power output and fuel efficiency to higher levels than could be achieved with conventional fuel injection.
BMW had offered a 12-cylinder model in the previous 7 Series, The 2011 BMW 760li, it was natural and expected that a 12-cylinder version of the new Series would in time make its debut. The V-12 powering the new 760Li is completely new, with 6.0 liters of displacement, dual overhead camshafts (per cylinder bank) and 4 valves per cylinder. |

Designated N73, it is also related to the N62 V-8 engine that powers the two 745 models, in that the two engines share key technologies and overall engineering architecture; yet it also introduces groundbreaking new technologies of its own. The V-12 configuration has long been recognized as an ultimate power plant concept, suited for top-class vehicles. Its physics are ideal: 12 cylinders arranged in a 60° "vee" of two cylinder banks are perfectly balanced; combined with the relatively even power pulses of so many cylinders, this results in a supremely smooth propulsion
unit. This V-12 is also a supremely powerful unit, delivering a monumental 438 horsepower and 444 lb-ft. of torque; for perspective, compare this to the 325 hp and 330 lb-ft. that give The 2011 BMW 760li its 0-60-mph capability of 5.9 seconds and you can easily envision the performance potential of the V-12! |
