The 0-60 times below may not be 100% accurate so correct me if you find something wrong. The V6 time i put below is an estimate based on what we know of the engine in the CTS.. I looked at multiple sources about the mustang times so they are pretty accurate..
Well 0-60 should be below 6 seconds for the V6 Camaro as that is what the CTS can do it in..
The V8 automatic got the 0-60 in 4.6 seconds with some tuning while the manual got 4.9 seconds according to the latest info we all received this last week as you all should know already

.
"The aluminum 4.6L SOHC V8 engine on the Mustang GT sports a 3-valves-per-cylinder head arrangement. The resulting output? 300 horses and 320 lb.-ft. of torque. Or, if you prefer, 0 to 60 in 4.9 seconds.* Blink at your own risk.
*Road & Track, April 2005." according to Road and Track testing.
A 2007 GT350 does 0-60 in 4.7 seconds while a stock 2007 GT does it in 4.9, the same as in 2005..
The V6 mustang in 2007 does it in 6.3 with a skilled driver on a manual at the fastest and that time may not be stock. Most of the 0-60 times for the V6 come around 6.6 for the V6 Mustang which puts the V6 Camaro at 300HP ahead by a wide margin..
Just to get a feel for what to expect with power and what was considered lots of power and speed just a few years ago.. This is a good read below..

"We recorded a best run of 12.8 seconds at 120 mph, and our best 0-60-mph time was 4.7 seconds."
0-60 time of 4.7 seconds for the SVT above..
Now this a 2003 SVT Cobra priced at $47,000 with extra's and being $33,000 stock... Five years later and the stock automatic V8 Camaro will do 0-60 in 4.6 for under $30,000 and be able to beat this amazing Mustang SVT Cobra that is lighter and has more Horsepower to boot in a straight line. And will have IRS as well..

Around a track with curves, the Camaro should be more agile because of a better IRS. This SVT above does have IRS but if I recall, they never fit perfectly on these older SVT's but at least they had them... So the V8 and the V6 will be great buys when competing within their own price range of sports cars..
