C7 Corvette Stingray chief engineer Tadge Juechter explains the choice to go with a 6 speed automatic transmission (and not 8 speed) for the 2014 Corvette – see 10:30 into this video.

Essentially, the reason is that the 6 speed is good for high torque engine like the LT1, while fitting an 8 speed just adds weight and mass.
