Default New MPG standards

I wonder what the new MPG standards announced today by Congress will do to cars like my Tahoe and My Z06 for the future?

Will we all be driving lightweight under-powered electric Ed Begley Jr cars/bikes in twenty years?

Yeah, they must think we're stupid. They're trying to tell us they just saved the average driver $700 per year in fuel cost. They think we don't realize that the cars will cost more and we will have to pay a "luxary tax" if we want to drive a car with any kind of power.

People who bring these bills to congress do not understand how engines work. Automakers don't just have a gas mileage **** that they can turn.

True, they don't understand cars. Incredibly my Z gets great mileage (28 mpg) on the highway , especially when you set the cruise at 65 mph.

Seriously, this is a reason why I bought my Z now rather than wait. I think 20 years from now the "Golden Age of HP" will be thought of as 2001-2008 not '65-'71.

I wouldn't get too worried, cars that were putting out 400+hp in the sixties and early seventies were getting 8-10mpg. I've also seen some info on AWD electric prototype sports cars that are capable of 0-60 times in under 3 seconds. You'll just have to play V8 sounds through the stereo.

What would happen if you took an Ls6 and seriously detuned it. Would your mpg increase, or would it decrease because the engine is no longer operating at peak efficiency?

they have the cylinder on off software working pretty good now, especially with direct injection. the cars will have more horsepower and get 40 mpg hiway..just watch!

Default live long enough to see history.............

If you live long enough you see history repeat itself in many areas. This latest US government intervention into capitalism is not unlike the mandated smog laws (1966-1971)with help from increased fuel cost and rationing (oil producers conspiracy) along with greedy insurance companies leading to the dramatic performance slump of the muscle car for 25 years.
I know that my muscle cars just increased in value because of this pending legislation. We already knew in 2002 with California/ CARB AB 143 pushing for a 27% decrease in non commerical vehicle emissions that the next government push was under way.
Just as you will never see the 60's muscle cars produced again , shortly you will see a sharp drop in new car performance with the help of high fuel prices, the perpetuationof this global warming myth and this Federal mandated 40% emission reducing from auto makers.
( personal editorial note: science can not provide a acurate 5 day weather forecast with their computer model. But science claims to be able to predict weather 50 years from now based on computer model developed from observastion of Venus. Ya , right).

History always repeats itself. You won't see me driving a modified hydrogen Vette. LOL

I felt things like this were in our future and figured if I was ever going to buy another high performance car the time was now. Mighty glad I did!

But you guys are forgetting one thing. When we bought our cars, what was the first thing we planned on doing....Modding them. This means that the factory cars are not near as efficient as they can be. The cars won't be very fun to work on in the future, but if the manufacturers make the cars as efficient as possible right out of the factory, then I have no doubt they can make a car with 400+ hp and still get 35 mpg. Just my .02 thou.

Show me a 'modded' LS6 that gets 35mpg since GM supposedly turns down the MPG **** before the car was shipped to you.

Trust me, take one thermodynamics class in college and you'll see why it's impossible for a high-performance gas engine to ever reach what the Feds want.

I agree with you, there is no modded ls6 getting 35mpg now. However, I'm sure high end sports automakers and engineers may know a bit more than you and if 35mpg is what is needed to get government approval, then I'm sure they'll make it happen. There maybe a little more science involved, but if thats what it takes to make money, then without a doubt we will see it in the future.

with 350+ HP cars getting 35mpg in the future..

1) Govt MPG standards are an avg for the whole line. They can keep the Vette and add a motorcycle based car.

2) Govt MGP standards are a joke. When MPG increases, so does driving! NO CHANGE in overall fuel usage and emissions. The Gubment needs to EDUCATE the American regarding the importance of a lifestyle change that is more environmentaly friendly.

Move closer to work, ride a bike, invest in "green tech," etc.

We don't need to change the auto industry. Let capitalism handle it. We, as a country, need to change the way we live. We do a lot more to pollute than drive....

You are the one who is disagreeing with the real engineers and auto makers. What makes you qualified to make these assumptions?

Not soon after I bought the Z, I read a story (I think it was Popular Science) about cars of the future, fuel cell technology, etc. It made me realize that our cars will be some of the last breed of high performance gas burners before fossil fuels go bye-bye in favor of greener alternatives. Those of us that were brought up on dino oil will end up paying a hefty premium at the pump someday just to take that weekend cruise. And we will.

Enjoy these cars (and internal combustion) for as long as you can. Their days are truly numbered and I truly believe that I will see in my life time (God willing) that internal combustion based cars/trucks will require a special registration (and the tax to go with it). The traditional "fuel pump" will become more difficult to find by 2025.

I actually took two thermodynamic courses in college, and I never said that you can take a Z right now and mod it to get 35 mpg. what I said was that we add headers, and the x-pipe, and a diffeent cam, and heads, all to N/A a car and free up the horsepower that is confined by backpressure and allow the car to breath as much as possible.

I said that with knowing that, I do not doubt that they will make a car with 400+hp and still get 35mpg in the future. People need to read threads and understand what is being said instead of making assumptions.

Default I love my Vette

I cant wait until I press the pedal to the floor in my 02 z06 sometime in the 2020s and hear that engine roar next to all those flimsy biofuel powered cars....when asked...I'll just say "yeah, its a blast from the past"
