Trucking Cody
Elio Fan
I know more about trucks then cars, but the idea is the same.
Is elio using a direct drive transmission? Running in direct gear instead of overdrive can significantly reduce the power loose caused by the transmission. The loss in top speed can easily be compensated for by useing a different rear end ratio. (in elios case, front dif ratio) I run my trucks with a lower number rear end in a direct drive set up. I have the same performance as a traditional od truck, but I get much better mpg in the direct gear (top gear on my trans)
So, is the elio using stupid overdrive trans like every other car on the market or have they opted to use a direct drive trans to save fuel at cruise speed? If they are using a od trans, can i swap out the front dif for a lower number and run it in 4th? (im guessing 4th would be direct if it's an od trans?)
Are they using standard diffs or highly custom diffs that i could not easily replace?
Using transmissions with a direct top gear in my trucks saves me about $10,000 each a year in fuel.
I'm really hoping they didnt overlook this mpg saver, but i dont see any info about trans ratios. They also didn't respond to my email asking about it.
In all reality, overdrive is just compensating for a poorly speced differential and is a scam perpetuated by auto manufactures. For those of you that dont understand this concept......
in an od trans vehicle, the output of the trans is faster then the input when in top gear. To compensate for this there is a higher number differential which makes a huge reduction in speed so the axle speed is much lower then the trans output speed.
In a direct drive set up top gear is a 1 to 1 ratio. motor speed on the input of the trans is the same as the output speed. Do the power going strait through the trans and no gears being used, there is less lost power. since the output isnt faster then the input, the reduction in the differential is less. With a properly speced trans and dif, you have the same power in first gear and the same top speed, but, while in top gear you use less power in a direct set up.
