The new Corvette C7 ZR1 is attacking the Ring at full speed and with a loud V8. The ZR1 is the most powerful model of the Corvette series and it will be the latest, and perhaps the last, addition to the C7 generation. Rumor has it that the car will output 700 horses, an increase of about 50 HP over the C6 ZR1. Enjoy viewing...and listening!
