Default Re: 14.5 MPG's!!!

Numbers I quoted were based on fuel used and actual mileage. No tricks from the computer, I never believed the readings on my '03. I too can't drive 55. I was just suprised by the results on a portion of my trip. I had never dissected the different impacts before but the road trip provided a great opportunity. If I could figure out how to keep it below 2k rpms while keeping up with the traffic that sure would be nice. Unfortunately 80 is just keeping up on I-10.

anyone ever hear of a gearvendor. i know its something noone might even consider, however, its a cool transfer-case unit that splits your gears.

For example, your traveling 65mph around 2k in 4th/od gear with is about a .63 gear ratio, without the final. This is with te gearvender disengaged.

With the gearvendor engaged, you split the SAME gear and end up aroud and est. 1300-1500rpm, still doing 65mph. Just like a regulr 3rd to 4t/od gear change.

Now, im not sure if they have tried to implement one in an H2 and it is costly, around 2k, but you not only get an improvement in gas mileage, but you theoretically end up with 8 foward gears instead of the usual 4 gears.
