An HPE-upgraded C7 Corvette became the first C7 Corvette to reach the double-century mark this month when it reached 200.6 mph on an unopened section of the Grand Parkway in Texas.

The run took place on a closed section of the newly completed segment E of Texas State Highway 99, which is also known as the Grand Parkway. It is located west of Houston, according to Business Insider.

The milestone was accomplished on Dec. 11 and the Parkway will open Dec. 21.

Hennessey Performance Engineering co-founder John Hennessy was behind the wheel during the milestone-run. The run was verified by the VBox GPS-based data acquisition system and through a radar used by Texas DPS State Troopers.

"The road is perfectly smooth and the Corvette was very stable and easy to drive at 200 mph," said driver and company founder John Hennessey. "I'd put the Texas highway system up against any other highway in the world, including the German Autobahn. Our roads have proven to be smooth and safe at speeds well above 200 mph. Of course, under normal driving situations, drivers should observe speed limits that have been determined to be safe for travel on the road."

State officials were also on hand during the run so they could test out the new EZ tag toll system.

The new toll road section connects Interstate 10 with Highway 290, according to Business Insider.

 Hennessey also achieved 164.3 mph on the Grand Parkway while driving a HPE600 supercharged Chevrolet SS.
