With the growing focus on global warming, we might see a huge crackdown on emissions within the next ten years that forces most cars to be of a hybrid or maybe even fully electric design.

All of today's cars, including the Mustang and 'vette, pass strict emissions standards and are quite environmentally friendly. The hybrid technology is very, very expensive and is not yet conclusively more fuel efficient than regular gasoline cars. For example, a hybrid Honda Civic is not that much more fuel efficient than the regular gasoline version. But the hybrid version is quite a bit more expensive. Time will tell on these technologies. But I think there will always be a craving and demand for high horsepower cars, especially now since the technology for building them is so much better.

I kept track of my Aveo's mpg over the last 4 or 5 fillups...

I've gotten from 19 - 23.

Yeah, the Aveo's mpg sucks...

Well, it only has the 4.8L in it, which doesn't help. Then on top of that I have a 6" lift with 35" tires and 4.56 axle gears.... not necessarily the best recipe for fuel economy.

Well, it would seem the 4.8 would get better milage because it has less displacement, but with the bigger tires and all it is pretty under powered. Eitherway it is a hog at the pump.

LS3 and other engines/transmissions

Ok, I've been hearing everywhere the probable engine that will be put into the Camaro is the LS3. I don't know how true it is, nor do I care.

But I did find this site through GM.com that lists spec sheets, power plots, and general descriptions of every engine and transmission in the generals stable.

THE LS3 IS SUPPOSED TO BE A CAR VERSION OF THE L92 TRUCK ENGINE

so have fun fun reading up!!!

I took a look through the build sheets on different engines and didn't come across either the LS3 or the L92 engines. It went from the LS4 to the LS2 and then the LS7 at the bottom of the page. Any where I missed?

At the top of the page, there is a subtle link to "Truck-Engines" that has a different list. You can find the L92 on this page:

I figured the 403HP advertised had to be under rated. That sheet has it at 417 hp.

By comparison, the L76 (The Truck version of the LS2) is rated at 366 hp. We all know the LS2 was rated at 400hp: a 44hp difference.

Translate that to the L92/LS3.....

This puppy is going to blow away all expectations! If this thing is released later in April with only 425hp, then they severely restricted it to keep the hp gap close between the LS2.

450hp is very possible here!

I know, isn't that great

Is that enough excitement?! I would never have believed that we would see over 400 HP and ~30mpg.

Now for the car to just begin production!
