Have not driven the new Camaro, but informal questioning on my part indicates that people care less about the engine or ergonomics of that car than "Dude, it's a CAMARO." I was not very impressed with a 2011 3.7L V6 Mustang
that I rented. It was an automatic and the transmission is geared for fuel economy, meaning the engine never has a chance to really wind out. Don't get me wrong - it was quick - but it wasn't slap your head back against the headrest, spin the tires in all five gears, fast.
The Camaro and Mustang both once were optioned with four-cylinder iron lung engines that could make barely over 100 HP, and their V6 versions were not much better. So the only one "worth having" if you were an enthusiast was the V8-powered SS or GT model.
If you're looking at a Mustang or a Camaro simply because you want a sporty car that looks good, then the V6 models of either will have plenty of get-up-and-go for you, especially if you get the manual transmission which gives you more control over the powerband. Otherwise, Mom knows best... if it ain't V8... it ain't s***.
