0-60 in 3.7? How do they know? Have they tested it yet and got the 3.7? NO! GM is claiming it will achieve this, but GM also claimed the C5 Z06 will achieve a 3.9 0-60 and it never did. So don't be fooled people. There are just claims/educated guessed/estimates. We do NOT have any official numbers for 0-60, 0-100, 1/4 mile, or 0-150!
