The BMW 760Li is the elder brother of 750Li which has the now ubiquitous 4.4-liter twin-turbo V8 good for 407 hp and 443 lb-ft of torque. Even better, is the mighty heart of the 760Li with its soon-to-be shared with Rolls-Royce 6.0-liter twin-turbo V12 that not only makes 537 hp but 553 lb-ft of gravity defying torque. That much grunt lets the big dog hit 60 mph in 6.1 seconds. Both cars are electronically limited to 131 mph.BMW has already designed a suitable suspension component (be it dampers, bushings or strut top mounting points) to account for all the extra weight. Moreover, as the new factory panels are in fact a perfect match to the parts they're replacing, the High Security cars fit together better and are more tightly sealed -- good news in case of gas attacks. And speaking of gas attacks, there's an assault alarm that automatically puts out fires under the car and in the engine bay. The assault alarm can also detect excess gas levels and automatically shut the vents, raise the windows, locks the doors and pump in purified air.
