Dutch “efficiency enthusiast,” Allert Jacobs has modified a Honda Innova to get 199 miles per gallon:

The Honda Innova is no slouch out of the box, returning 133 mpg from a 125cc engine producing a whopping 9 horsepower. But the Dutch “efficiency enthusiast,” as EcoModder calls him in its write-up, couldn’t leave well enough alone.

He’s put in a lot of miles on recumbent bicycles and knows a thing or two about aerodynamics, so the first thing he did was convert the Inova to a recumbent by moving the seat waaaay down on the bike’s step-through frame and moving the footpegs. That and a simple fairing boosted the bike’s top speed from 56 mph to 69 mph. Together with taller gearing, Jacobs raised his fuel economy to 156 mpg.

But why stop there? Jacobs spent several months designing and building the full fairing, which splits in two vertically just behind the windshield so he can get in. While it looks like you’d blow right over with a sneeze, Jacobs claims the bike is stable even in a 40-mph crosswind.

The bike’s record is 214 mpg, and Jacobs says it averages 199. But he’s not done yet. He’s shooting for 235 mpg — which for those using the metric system is 1 liter per 100 kilometers.

If you travel 10,000 miles per year, going from 133 mpg to 235 mpg saves you 33 gallons of gas, or about $83, per year.
