That is with the last 5 miles driven on Pennsylvania Ave (heading into DC)!

I must say I am thoroughly pleased with this, especially after trading in my 16mpg truck!

I've played with the tripmeter and got similar results for pure highway trips. It will usually average back down with the few miles you might drive before and after the ramps.

However, still 30+ for highway time is a good thing.

Try going 55-60mph and it goes up even more.

I hate to say it, but it does pay to slow down.
