I totally agree it is time that we leave our mindset of V8 for the power because honestly gas prices are high and are not going down, and besides all that power does nothing for you it's not like you can drive extremely fast!!! We don't have an autobahn or autostrada here with a no speed limit left lane. Almost all our highways are speed limited so, what does that extra power do beside suck up gas. Please don't give me the merging into traffic crap..they do it all over the world with small displacement engines we can here!!!
That is kind of the entire point of cars like the Camaro though. Being able to accelerate fast (not necessarily exceeding the speed limit) is enjoyable. There will also probably be a number of Camaro owners who take their car to a track so they can enjoy the extra power in a controlled, safe manner.
Now this isn't to say that I don't agree that a 2.0L DI Turbo engine couldn't be a good option, I was just pointing out that technically by your bolded statement's logic, no one needs to build cars with more than 120-180 hp, b/c you never really
need more than that.
Depending on the state of tune of the 3.6L that we might be getting, the Direct Injection Turbo eccotec might even make more hp and tq (it makes more than the non-DI 3.6L in the Malibu), and if you've ever looked at the dyno charts for the 2.0L engine, it has very good power through the entire rev band, including the low end, thanks to its dual scroll turbo and excellent vvt system.
The Sol/Sky are lighter than the Camaro and don't seem to have terribly better highway mileage than other LS1 powered vehicles when equipped with manual transmissions (It is not uncommon to see even 30mpg with a 6 speed equipped LS1 Corvette or F-Body). This could be due to several things though, I've never driven a Kappa, so I don't know from experience, but I've heard the gearing isn't that great on it, and I know a lot of the parts were shared w/ the 355's (rear end, transmission?), so that could be something that hurts the Kappa's mileage that could be rectified to allow the 2.0L excellent mileage in the Camaro. Another thing to consider that this same engine in the Cobalt SS Turbocharged gets right about 30 highway mpg, and the Cobalt is much lighter than the new Camaro will be. So I think that getting better mileage than the Cobalt without totally neutering the Camaro via gearing might be pretty hard to do. It also has again, a different transmission and final drive ratio, so a lot of this is speculation, but it's fun and its really all we can do at this point.
Either way, having the 2.0L as an option doesn't prevent someone from getting the V8, and the 2.0L Turbo will be making a lot more power than the last 3800 v6 F-body cars. Having a small displacement turbocharged engine might also broaden the appeal of the new Camaro, in addition to providing a higher efficiency alternative to someone who might otherwise not chose a Camaro, there are also lots of enthusiasts that prefer smaller forced induction engines.
