Torque is rated at 500 lb-ft., nothing crazy by the X6 M's competitor standards, but the innovative turbocharging system BMW has developed should make sure all that thrust is available at a moment's notice with little-to-no turbo lag.A complex intake and exhaust management system BMW is calling Cylinder-bank Comprehensive Manifold (CCM) makes sure that reused exhaust gases are passed through the turbo system and back into the manifold with every cylinder rotation rather than in the waves of power found in conventional turbos. The result is a promised constant stream of boost, and at 21 PSI there's plenty of it.
To prepare for all that boost, BMW has beefed up the new 4.4's internals dramatically. 4.5 super-smooth seconds through 60 mph tell the tale that such a heavy and tall monstrosity has true sporting potential.Price info has not been finalized. The Cayenne Turbo runs a hair under $100,000 to start, so expect something in the $90,000s.
