MAX Car 109: Reducing Rolling Resistance

MAX isn't just streamlined - MAX has its rolling resistance down to a minimum too, thanks to low-drag tires and lubricants. Here's a video to show how much it matters.

MAX Update No. 103: The Metro Miata “Cold Rod”

If MAX is a bit too Spartan for your tastes, here's a homebuilt high mileage sports car that's a bit more plush - a Mazda Miata with a Geo Metro engine - and it's coming to the Mother Earth News Fairs.

MAX100 The Shows Must Go On

A big crowd likes MAXine better than MAX, and I’ll see you soon, at the MOTHER EARTH NEWS FAIR in Puyallup, Wash.

MAX Update No. 97: Deer Prudence

MAX finally got a deer deflector, after three years of writing about how much it needs one. It'll give a bit of extra rollover protection, too.

MAX Update No. 96: Jevons' Paradox and Gore's Dilemma

Does 100 mpg fuel economy justify cross-country recreational travel? Maybe so and maybe not, but I need to be careful—increasing fuel efficiency can increase fuel consumption if you increase your driving, too.

MAX Update No. 94: FrankenMAX

MAX gets a temporary mash-up of old and new style body parts (the new nose is at the fiberglassers' having a mold made so we can make more of them) to get road-legal for a trip to Canada.

MAX Update No. 93: Plugging Away

Jack has dismantled MAX's body and is making molds from the body parts, so other MAX-like car builders won't have to duplicate his work.

MAX Update No. 91: The Light Underbelly

The tail end of MAX's bellypan (diffuser) gets tuft tested, and the attached video shows the results. This was the finishing touch that got MAX its 100 miles per gallon on the highway.

MAX Update No. 89: Good Work Car

To improve MAX's versatility, the passenger seat is removable, which converts MAX from a couple carrier to a cargo carrier.

MAX Update No. 80: Cooling Tests and Travels

On a summertime cross country trip from Oregon to Ohio, I restricted MAX's radiator inlet air a little at a time, demonstrating that very little inlet area (28 square inches) provides sufficient air for cooling.

MAX Update No. 69: Two Tired to Test

MAX got a new set of high efficiency Goodyear tires, and a second set of wheels so we can do comparison testing. Will the difference be detectable to our low budget testing technology?

MAX Update No. 68: Idle Speculation

Hybrid cars save fuel by shutting the engine off at idle (among other things). Does MAX burn enough fuel at idle to be worth the effort? Our honey bear can tell us.

MAX Update No. 66: Go With the Flo

Technology marches on. It comes at a price, but a FloScan fuel consumption and mileage meter could give me instant feedback on MAX's fuel efficiency.

MAX Update No. 62: Throttle Management

A treatise on the difference between a gasoline engine throttle and a diesel "throttle," what that means for MAX, and how the difference was overcome.

MAX Update No. 60: An Unplanned Body Modification

So here you have it: MAX with a crumpled rear fender, crumpled trunk section, a turn signal bashed out, a door knocked loose, and a flat tire. It's fully reparable, but not today, and not in time to drive to the MEN Fair.
