If you want to save on gas get a good fuel economy car. If you want a fast car, get a muscle car. You pretty much have to choose one over the other.
maybe because its light weight!!!
Yes if you want better road holding. No if you want less friction and better fuel economy.
My site has quite a bit of info relating to this http://www.maintainyourcar.com/ It depends on what car gives better fuel economy. Some cars that were designed to run on higher octane will give you better performance when using the correct fuel and your fuel economy. Check with your manufacturer. With a Mercury Cougar You could try 91 octane or 95 octane, at least 91 octane will give you a bit better economy Consider servicing the car too that can help!
Corporate Average Fuel Economy (cafe) has to do with fuel economy numbers for a car maker. The US government mandates certain economy ratings.Corporate Average Fuel Economy (cafe) has to do with fuel economy numbers for a car maker. The US government mandates certain economy ratings.
No Egr (exhaust gas recirculation ) is to help better fuel economy
It depends what you mean by better. Performance wise, certainly not. Fuel economy, slightly so. Price, no.
Both would be good on fuel economy but Honda has a better overall reputation.
Maybe, Some cars require a High octane fuel to protect the inside of the engine from damage. If a car is rated to run on "Regular" there is normally no advantage to Higher cost fuel Some engines can run on Regular but as detailed in the manual will make more power and better economy on better gas. Then yes better fuel will help.
There are websites where you can check the fuel economy of each car. One good website is fueleconomy.gov. You can search about any car to compare the mileage.
diesel will be powerful
the muscle car was built for performance not economy at least not the years 1966-1974.
The car known as Chevrolet Minivan has a fuel economy of 11/17 mpg. The car may be purchased while new or used from various different stores or car showrooms.
