And yes the ZR1 is faster than a Ariel atom in this track
The M3 is pretty impressive! Sick lux car with same time as the Porsche's. And I'm pretty sure the 2010 mustang GT with the 5.0L 415hp will be a lil faster than the camaro, not by much tho! This one is lacking power big time with the 4.6 300hp but still did a respectable time compared with the NISMO!
The fastest car still the Viper ACR from 2008, SICK car!! Read the article, it's pretty cool.
