It'll be interesting to see what the next gen Z can do. I've been watching the Solstice coupe and Z rumors very closely and there's a good chance one of those two will be my next car.
Against the current Z, a more powerful Solstice coupe would be a very interesting rival. The extra weight of the Z could allow a more powerful Solstice to beat it.
But the rumors are the next gen Z will be losing some weight and gaining some power.
I'd expect when both new cars are out, they'll still match up similarly to how they do now: The Z will be the more serious performer while the solstice will be a little more 'fun' while still being a decent performer. The Solstice is also likely to remain a better bargain with a loaded version topping out at $30,000 while the Z will likely climb close to $40,000 with some options.
I had been hoping the Solstice would be a true coupe and offer a more rigid body, but I'm starting to like the compromise of the targa top.
I'm very anxious to see the next Z. Rumors are it will be unveiled in fall. At this point, I think the Solsice is in the lead, but that's largely because we don't know anything about the new Z yet.
As for the 'Monza', are you thinking that was just an April fools? Have there been any additional post April 1st comments on the Camaro sites you visit? I was hoping it might be real, and I thought these new engine comments might have backed it up.
