VonoreTn Report post Posted October 17, 2009 Ok, here is something I tried last night based on logic I had done in my head, the logic being that the more miles you spend with the ICE off, the better your mileage. Since the ICE will go off under light load up to 47 mph, I figured that if I drove from my home to Maryville, Tn. on highway 411, where the speed limit varies from 50-55, at just under 47 mph, I could get optimum mpg. The nice thing about this road is that there are few stop lights, light traffic, small rolling hillls and 4 lanes, so I never blocked traffic. And it worked. Going to and from Maryville, about 60 miles at 45 mph on speed control, I averaged 51.2 mpg, based on the trip FE readout. The ICE was going off going down the minor hills. I know that you can get slightly better mpg if you take the speed control off, but the problem with that is that if you accidently exceed 47 going down a hill the ICE kicks in, plus without speed control it is easy to drop off too much speed going up hills. That takes way too much focus. It was cool enough that I did not need AC, or much blower. It was night, so my lights were on. 50 mpg puts me in the same range as large engine motorcycles. When someone figures out how to get the ICE threshold speed to 65 mph, without a 1000 lbs of more batteries, that might be an mpg break-through. Quote Share this post Link to post Share on other sites
