Michigan International Speedway is still a palace of speed.

NASCAR Sprint Cup driver Clint Bowyer said he went 217 mph during the Wednesday morning session during a Goodyear tire test at the 2-mile track.

"That's white-of-your-eyes fast," Bowyer told reporters and staffers at the track.

Dale Earnhardt Jr., Greg Biffle, Ryan Newman and Trevor Bayne also participated in the test.

Earnhardt Jr. said he reached speeds of 212-215 mph on the straightaways and about 180 in turns.

“This is one of our better tracks, and our fans will probably say the same,” Earnhardt said. “Having the success here over the last four or five years has given us a lot of confidence when we come here, and I think that’s why Goodyear brings us to test.

“I enjoy racing here. It’s a fun track. The asphalt is really aging well and it’s just going to keep getting better and better over the next couple of years.”

MIS was repaved in 2012, and drivers have since posted testing, practice and qualifying speeds that rank among the fastest in NASCAR.

The track hosts Sprint Cup races on June 15 and Aug. 17.
