Name is Tim, live in Houston, Texas. Many of you won't believe the following but it is true and I can substantiate the claims. Now, don't throw stones, but I drive a 2000 Chevy Corvette. Not considered to be a good MPG car but........ I have done several modifications with INCREASED the horsepower and resulted in tremendous gas mileage increases. Of course, this is with the proper, conservative driving habits to squeeze mileage out of each gallon of gas. I am still trying to see how good it can get while still being SAFE!! I DON'T coast downhills (that can be very dangerous) I DON'T tailgate (dangerous and illegal) I DO use my A/C (old and can't stand the heat) but I DO NOT use heavy acceleration (buses leave the light faster than I do sometimes!) do NOT use high RPMs between shifts (6 speed), do NOT speed (well, no ALL the time anyway - LOL - hard to go slow in a Vette). I recently changed out my engine with a 2003 Z06 engine MODIFIED with an output of approximately 530BHP, dynoed at 461RWHP. I am using full Royal Purple in everything, full performance exhaust, modified intake (large diameter filter which increased the air intake surface area over 500%!) and am currently getting 20MPG in town and 38MPG on the highway with the cruise control set at 70MPH. If I monitor it myself, I have attained as high as 42.7 MPG. Not bad for having the performance available if you want it (0-60 in less than 4 seconds) 1/4 in less than 11 seconds. The EPA rating for this car in 2000 was 18/28 so by increasing engine efficiency / performance and modified driving behaviour, I have a 11% increase in city driving and a 36% increase in highway mileage. Not bad. Now to try some methanol/water injection AFTER the throttle body. Developing a metered plate to work in conjunction with AFR computer control. Hoping to double mileage and also increase performance at the same time.
Now, if I can find someway to afford one, I would love to have one of the new Tesla that is electric and will outperform my Corvette, goes over 200 miles on a charge and only cost about $.01 per mile to operate. Only drawback is the price, $109,000.00
Welcome. The Corvette, while generally not seen as a good car for fuel economy, really can be with the right driver. It's got gobs of torque even down to idle speed, so you never have to rev it up to get where you're going. It's got very little aerodynamic drag. GM V8 engines are very efficient (for a V8). I assume it has a very tall 6th gear.
A couple times people have described that the Vette is actually more efficient at something like 75mph than at 60; I remember an aerodynamics discussion that explained it as being due to a change at that speed in the way that the air flows.
I have been hypermiling for awhile now. 1998 Merc Mystique 2.0 4 cyl w/5 spd manual tranny. Bought the car 10/05. Started out getting high 20s to low 30's. Last tank was 48.899 MPG. No mods unless you consider a SG II and full moon hubcaps as mods.
I drive a 2006 Scion XB 103 miles a day to work. I started with an about 29 to 30 mpg. When I got 60,000 miles on it I changed my spark plugs with the E3 diamond fire plug. With in 4 tank fulls of fuel my mileage was 34 to 37. I use Mobil One oil and change it every 5000 mile. My other car is a 1998 Lincoln Continental with 165,000 miles on it. I get about 23 mpg on it, not bad for a V8.
