The energy balance with ethanol has been greater than 1:1 for some time now, and can approach 2.5:1 with modern technology.

But I agree with you.

Edit: Looks like corn ethanol is a rather paltry 1.3:1, while Brazil's sugarcane industry is 1.8:1.

That's pretty ballin. Better than 1.

Hopefully they don't go too nuts with this. If the US starts using imported food for alcohol production, that means millions of poor people around the world die because US demand drives up the cost of food and they can no longer afford it :awe:

They're not thinking. They want to push policies and regulations that will make everything more expensive for us. We see what engineering can do now. We have big v8's making 400+ hp and getting 25-30mpg. Smaller engines are getting 2x that. Now the requirements have changed and you're forcing the mfgers to abanded what they are doing and start all over.

This is a push to help someones corn growing buddies out. There are much better alternatives. Sugar beets, sugar cane, switch grass, ect. Corn is the absolutely worst plant to use for bio-fuel.I admit, it's cool tech to make fuel from plants, but unless we can net more enregy from the fuel we create than we put in, it's pointless. We also need to differentiate farms based on food and fuel. Ethenol is the cause of most of the food costs increases.

Me thinks thou dost exaggerate just a bit.

Best I could find was 26mpg out of the Corvette in highway driving only. None of the big V8 powered muscle cars topped that figure and city driving is abysmal at around 16-17mpg.

Mustang GT is 26 also. Charger is 25.

I wonder how well the 5.7L Hemi will do when they add a few more gears? 8 speed should be out by the end of this year. Should get the highway mileage up there when cruising on 4 cylinders.

The 2012 Grand Cherokee should have a new 6 speed auto with the 5.7L V8.
