Interesting review on the Toyota Prius.

[MrFebtober]

Amazing what difference 1000 RPM can make. I certainly wasn't bogging the engine down, but I was driving a bit below peak torque, so as you say, the engine wasn't turning at peak efficiency.

My boyfriend's 99 Corvette makes about 37mpg on the freeway travelling at 70mph, and the same at 60. Not only is the car very aerodynamic, but it makes enough torque that gearing it taller was possible, and he only turns about 1400 RPM at 70mph in 6th.

And all this talk of diesels - there was something on TV this morning that in CT diesel is now over $5 a gallon. Are people factoring that in when they are giving diesels the mad props?

Most gas stations near me are around $5.50 for diesel, and the highway service stations are usually a bit higher.

Altho, compared to my Acura Integra's (RIP) 32 mpg I've noticed a HUGE difference in the amount of fuel the CR-V uses.

I hear you on the Integra, I miss mine so friggin' much(rotten car thieves) Even with over 120k miles on it I got over 30mpg.

My current car has a display setting that shows instantaneous MPG and average MPG. It's a V6 turbo and a pretty heavy car. I've found that I get the best MPG on the highway when going 70-75mph. And that's straight from the car's onboard computer, so in my case driving slow equals poor gas mileage.

what does he have done to it?

http://www.cargurus.com/Cars/Overview-c404-1999-Corvette.html <- site has it spec'd out at 25

not saying 37 isn't possible, I'm just curious what he has done to it? Intake? Headers? Exhaust?

those upgrades alone on my Integra increased my gas mileage by a considerable amount.

He bought it with billy boat exhaust, that's about it.

I'm not sure why they rate them so low, his 92 made similar mileage(had different gears though), and was rated at about 25. I make 28 in my automatic 86 on the freeway, and that's with the torque convertor not going into full lockup like it's supposed to.

Vettes get extremely good mileage on the highway. Had a friend get 35+ with a supercharger. Thing was turing something like 1200rpm at 65-70

Getting angry at those people is no different than getting angry at people who don't pull their pants up all the way or people who wear a bluetooth headset on their ear: what the fark difference does it make to your life?

Getting angry at people who make different choices than you do is just silly.

I interviewed a woman the other day who wore her bluetooth headset for the entire interview. At first I gave her a look and she gave me one right back. But the look I gave her was trying to figure out if she had a hearing aide in. Then I saw the blue flash.

What an ass!

Do you know the final drive ratio?? I thought that was a pretty high number to. Corvette's are known for having an incredibly low drag coefficient. If the car is lowered or has good a good aero kit, this will also increase MPG.

Stock body, not lowered. I couldn't tell you the final drive on the 99, but I think on the 92 it was 3.07.

It seems awfully high to me as well. My dad's Corvette (2007, 6L, 6spd auto) gets exactly what the EPA says it should on the highway...25mpg. He sets the cruise control around 70 on his regular drive to/from his second home, and drives like an old man because, well...he's an old man!! (An old man with a very cool car!)

I will say that Vettes do get better mileage than most people would think. In addition to the other reasons mentioned, they are also very light vehicles.

I don't know what to tell you. It makes that type of mileage. Autos are less efficient, and the 2007 has a slightly larger engine, it makes more power, and it has a higher final drive ratio. How many RPM does your dad's turn on the freeway?

 

[c.n.budz]

Wait, is thread about Priui or Corvettes

It just seems kind of incredulous, 11 mpg above the EPA highway rating. In my experience, the EPA numbers are generally high. I'd have to ask my dad about the RPMs at cruising speed.

Sorry if I sound insulting, but I assure it's not my intention...I'm just being candid, and certainly don't intend to offend. Frankly I'm impressed by your knowledge of cars, I don't know many ladies who can speak authoritatively about shaved tires and gear ratios.

 

[Laurel]

I didn't believe it when he told me what type of mileage the car got either. It seemed insane that it did that much better than the EPA rated mileage, especially with that much power. There's not really much I can say to convince you, but here are a couple shots I snapped last June in the 92 while we were on a straight flat stretch of freeway. Sorry for the terrible focus, but you can see the speed and the RPM. The speed has to be adjusted about 10% because of the swapped gears, so 76 is really closer 70.
