Motorhead Messiah
Johnathan Goodwin can get 100 mpg out of a Lincoln Continental, cut emissions by 80%, and double the horsepower. Does the car business have the guts to follow him?

"Check it out. It's actually a jet engine," says Johnathan Goodwin, with a low whistle. "This thing is gonna be even cooler than I thought." We're hunched on the floor of Goodwin's gleaming workshop in Wichita, Kansas, surrounded by the shards of a wooden packing crate. Inside the wreckage sits his latest toy--a 1985-issue turbine engine originally designed for the military. It can spin at a blistering 60,000 rpm and burn almost any fuel. And Goodwin has some startling plans for this esoteric piece of hardware: He's going to use it to create the most fuel-efficient Hummer in history.
Goodwin ... is a professional car hacker. The spic-and-span shop is filled with eight monstrous trucks and cars--Hummers, Yukon XLs, Jeeps--in various states of undress. His four tattooed, twentysomething grease monkeys crawl all over them with wrenches and welding torches.
Goodwin leads me over to a red 2005 H3 Hummer that's up on jacks, its mechanicals removed. He aims to use the turbine to turn the Hummer into a tricked-out electric hybrid. Like most hybrids, it'll have two engines, including an electric motor. But in this case, the second will be the turbine, Goodwin's secret ingredient. Whenever the truck's juice runs low, the turbine will roar into action for a few seconds, powering a generator with such gusto that it'll recharge a set of "supercapacitor" batteries in seconds. This means the H3's electric motor will be able to perform awesome feats of acceleration and power over and over again, like a Prius on steroids. What's more, the turbine will burn biodiesel, a renewable fuel with much lower emissions than normal diesel; a hydrogen-injection system will then cut those low emissions in half. And when it's time to fill the tank, he'll be able to just pull up to the back of a diner and dump in its excess french-fry grease--as he does with his many other Hummers. Oh, yeah, he adds, the horsepower will double--from 300 to 600.
"Conservatively," Goodwin muses, scratching his chin, "it'll get 60 miles to the gallon. With 2,000 foot-pounds of torque. You'll be able to smoke the tires. And it's going to be superefficient."
He laughs. "Think about it: a 5,000-pound vehicle that gets 60 miles to the gallon and does zero to 60 in five seconds!"
This is the sort of work that's making Goodwin famous in the world of underground car modders.
...
Two years ago ... was driving a converted H2 to the ... nation's biggest annual specialty automotive confab, and stopped en route at a Denver hotel. When he woke up in the morning, there were 20 people standing around his Hummer. Did I run over somebody? he wondered. As it turned out, they were engineers for GM, the Hummer's manufacturer. They noticed that Goodwin's H2 looked modified. "Does it have a diesel engine in it?"
"Yeah," he said.
"No way," they replied.
He opened the hood, "and they're just all in and out and around the valves and checking it out,"
...
'Is it running?'
"Yeah, you can hear the fan going.'"
One engineer turned and said, "GM said this wouldn't work."
"Well," Goodwin replied, "here it is."
It's a long article, with some really interesting material in it. I've barely scratched the surface. But, if you want big powerful vehicles with great gas mileage and are enviro-friendly ... you gotta read this.
