a little quote about the new c7:

Those weight savings are important, because in order to meet ever-stricter crash regulations, develop a much richer interior and add performance, some weight had to be added back in the form of new equipment. Counterintuitively, Chevy tells Autoblog that if its engineers didn't have to care about fuel economy, the C7 would actually be lighter. How's that? The new small block incorporates features like direct injection, variable-valve timing and cylinder deactivation ("Active Fuel Management") trickery, all of which adds weight. The new engine management hardware alone adds 35 pounds, plus there's a further 5.5 pounds for the AFM exhaust valves (so the engine doesn't sound objectionable when operating in V4 mode), another 15 or so pounds for the steel torque tube to help improve drivability with AFM, etc.), and so on. Surprisingly good fuel consumption figures have become something of a hallmark in recent generations, and it was a top priority to preserve that leadership in the new generation.
