Just how fast will they go?

NASCAR Sprint Cup drivers continued to push the limits on speed at Michigan International Speedway on Friday. Tony Stewart topped 201 mph on Thursday, but that speed was eclipsed in the afternoon practice session Friday. 

Roush Fenway Racing's Greg Biffle led the final practice session at the track with a lap of 204.708 mph. Marcos Ambrose followed with a lap of 203.551 mph.

Overall, four drivers topped 202 mph and 14 were over 200 mph in the session.
