Z-28 release
The Z-28 was slated to be released as a late 2011, but as of now got pushed back even further. More like 2012-2013. But G.M. still has it in the works. It will have the same engine as the Cadillac sts-v (556 h.p. 6.2 liter)supercharged. It most likely will only be offered in 6- speed manual as the automatic can't handle the power. Estimated top speed of 198 m.p.h.
