What does a Ford Motor Company fuel economy technical expert do for fun at the end of the day?

He heads home to his own shop and custom builds an aerodynamically efficient, two-passenger, 3-wheel motorcycle capable of 125 mpg (US) at 65 mph (1.9 L/100 km @ 105 km/h) and a top speed of over 100 mph (161 km/h).  And then after using it for 3,200 miles (5,150 km), he puts it on eBay to make room in his garage for the next version which will be a plug-in hybrid.

“After working [on] improving conventional production car/truck fuel economy I wanted to try something with fewer constraints,” says EcoModder member John (HyperRocket).  Now there’s an understatement.

(It kind of makes you wonder how many house painters go home at the end of the day, budding Picassos, to toil on masterwork canvases…)

His street legal, 2-seat, tandem vehicle is registered as a motorcycle and was engineered for both high efficiency and fun:

• the drivetrain is from a Kawasaki Ninja: a 250cc liquid cooled, four stroke, DOHC 2 cylinder tuned with an exhaust gas analyzer for best efficiency & driveability

• six speed manual transmission

• weight: 505 lbs

• excellent 0.16 coefficient of drag, calculated through GPS-based coast down tests

• HID projector headlight up front, and LED’s elsewhere (front turn signals are integrated into the side mirrors for aerodynamics)

• safety features include 4 point seat belts, roll bar and front mounted IMPAXX crash foam as now used in NASCAR sides

John claims fuel efficiency of 105 mpg (US) (2.2 L/100 km) cruising on the highway at 65mph when equipped with the bling wheels and sporty gearing, and even better numbers with a couple of additional mods: “When equipped with the pictured motorcycle tires (not included) and a smaller rear sprocket it achieved 125 mpg @ 65mph.”  (1.9 L/100 km @ 105 km/h)

If you think a vehicle like this might draw attention, John confirms that with a good anecdote:  After being stopped by police and explaining the project to the curious officer, ‘back up’ was called in.  “Four squad cars showed up, several houses of neighbors came out and the whole thing turned into a spectacle. No ticket, everyone was genuinely interested in ecomodding!”

The trike’s eBay auction has a starting bid of $15,600 USD. While not questioning the design or workmanship that went into the machine, we wonder if that price will draw efficiency-minded bidders in these days of $2 per gallon gasoline.   Undoubtedly his work would have grabbed a lot of attention last summer, when fuel prices were driving people into a frenzy, paying utterly ridiculous prices for used Geo Metros to save money at the pumps.

Best of luck, John.   We’re looking forward to seeing what rolls out of your shop next!

A few months ago in a post about A/C alternatives I promised you I’d try some of the gadgets and get back to you. Well, summer has finally hit and in between sweaty drives around town I’ve been doing a little research. Here’s what I’ve learned:

1. the A/C shirts, according to some cycling reviews I’ve read, are kind of uncomfortable and don’t last very long. Coupled with the high price, I let this one pass;
2. this was the cheapest option, and therefore first on my list, stay tuned for more info;
3. seems like it would work better than #1, but again, cost is a factor. I might give this a try later;
4. definitely still on the to do list, expect an update on this before I shell out for #3;
5. this is definitely next up with the beaded seats already taken of, when I return from HybridFest this is my next mod.

Before thinking about these tricks for alternative A/C, I’d always thought those beaded seat covers were for weirdos. Luckily, the other founder of EcoModder told me that they did a great job of keeping you cool in the summer. I was a little skeptical, but when he showed me his beaded covers and I realized I could get a pair for just $26 dollars (shipping included), I figured it was worth a try.

The Komfort Beads showed up on my doorstep the day after I ordered them, and I went right ahead and threw them on both my passenger and driver’s seats. It wasn’t very hot outside, so I couldn’t tell how they worked during short trips around town, but today they got their first real trial.

The Date

When I removed my A/C (most of you will think I’m a fool, but it never worked anyway), I decided that the ultimate replacement would be found when I could go to a date and take a date in my car without showing up a puddle of sweat or reducing her to one. Today I got to put this to the test, as it was extremely sunny and blisteringly hot on the way to an engagement with a lady caller.

I won’t get into the date, but the beads were a success. When I showed up I was a little toasty, but my back felt much nicer than usual and wasn’t a pool of sweat. The seat was still slightly uncomfortable, but it was definitely refreshing to have my back feeling good. When she got into the car, she agreed. I’m sure she’s used to A/C, but I didn’t hear any complaints about the heat. The only negative seemed to be that the beads could tug at longer hair.

Success!

Yep, I’m going to call it a success. The beads don’t put you in a 70F paradise, but they greatly improve summer driving and reduce sweat. Especially for just $26 for a pair, this was a great deal. Does anyone have any other beaded seat cover brands they can recommend?
