CVT or 5MT?rangeman said:I've noticed a increase in my mileage when I draft (tailgate). What is your input on the subject.... I get an increase of about 15%. In fact my best mileage was behind a semi hauling caskets, I averaged 69 MPG for the whole tank.
Keep in mind (a) trucks are often one car length behind the car in front of them at 65-70mph (very dangerous on their part, but at least they can see over the car and anticipate, which you can't), (b) no doubt you'd stop faster than the semi if the brakes are applied full on at the same instant, but you need to add in your reaction time plus the time it takes you to realize that the truck is braking hard rather than just easing on the brakes, and (c) the draft decreases rapidly the further back you are (look at the closeness of NASCAR drafting, and they are at 150-200mph where the draft pockets are longer).james said:in my case I'm generally no closer to the rear of a truck than the truck is to the car in front, and I dare say I could stop quicker than 40 tons of loaded semi.
I wouldn't count on it. The exhaust stacks feed into the airflow over the top of the trailer which is then sucked down by the vacuum just behind the rear of the trailer.james said:Which you get no more of (maybe less) drafting close behind a truck than out in the general flow of traffic. Look at where the truck's exhausts generally are, and the airflow pattern behind it.
james said:I think that car carriers work the best, or moving vans. Anything that's low to the ground.
Tire treads too. I was on a trip today, and the tires on many of the semis that went by were making "I'm-about-to-separate" sounds. Scary!!Lenictavus said:i would definitely NOT recommend following a car carrier.. I was driving home one day behind a car carrier, and all of a sudden i saw this huge black what looked like piece of plastic or something.. coming straight at me.. so i swerved out of the lane (luckily nobody was next to me) and apparently the sun roof of one of the cars just flew off.. it looked like it weighed nothing at 70 mph but I'd still be careful.
